World Sea Turtle Day is a day to honor and highlight the importance of sea turtles. It is on June 16th because that was the birthdate of Dr. Archie Carr, the Sea Turtle Conservancy’s founder and the ‘father of sea turtle biology.’
Sea turtles have been around for at least 110 million years, as far back as the Cretaceous period and the dinosaurs. They spend their lives in the sea, except for nesting, and swim in almost all oceans. Sea turtles navigate through their sensitivity to the Earth’s magnetic fields. All species of female sea turtles return to the same exact beach they hatched on to nest.

Endangered
Six out of seven species of sea turtles are threatened with extinction, according to the IUCN Red List. The 7th is listed as ‘data deficient.’1

Importance
“Sea turtles are a fundamental link in marine ecosystems.” -World Wildlife Fund
Sea turtles keep the natural ocean environment and the food chain balanced. Following are specific ways in which they provide this balance.
Balancing the Food Chain
The largest sea turtles, the leatherbacks, consume up to 440 pounds of jellyfish daily. Loggerheads and Green sea turtles also eat them. As sea turtle populations decline, jellyfish populations increase. This not only affects humans, but it affects fish populations. “Declining fish stocks leave jellyfish with less competition for food, resulting in proliferation of jellyfish around the world. The increase in jellyfish is already proving detrimental to the recovery of fish stocks since jellyfish prey on fish eggs and larvae.”3 So the fewer sea turtles, the more jellyfish, and the fewer fish worldwide. This alone could cause devastation.
Certain fish “clean” the barnacles, algae, and epibionts (organisms that survive by living on other organisms) from sea turtles’ bodies and shells, sometimes providing their sole food source. Without turtles, these organisms would have to find another, potentially unsuccessful, food source. “Species associated with a host, such as sea turtles, are important to generating and maintaining diversity throughout the world’s oceans.”4
Sea turtles also provide food to many other species as prey. Many predators eat eggs and hatchlings, and even juvenile sea turtles. Sharks and killer whales sometimes eat adult sea turtles.
Last, but not least, some species, such as loggerheads, consume crustaceans. While eating they break the shells into fragments and create trails in sediment along the ocean floor, practices that both contribute to what is known as ‘nutrient cycling.’

Seagrass control
Sea turtles are one of the few animals that eat seagrass, especially Green sea turtles. It needs to be cut short constantly to stay healthy and to keep growing. Seagrass beds are important because they are the breeding and developmental grounds for many species of fish, shellfish, and crustaceans. Those species are consumed by many other species, so lower levels of seagrass impact the food chain, all the way up to humans.5
Additionally, seagrass control provides balance to the ocean. “Without constant grazing, seagrass beds become overgrown and obstruct currents, shade the bottom, begin to decompose and provide suitable habitat for the growth of slime molds. Older portions of seagrass beds tend to be overgrown with microorganisms, algae, invertebrates and fungi.” The Caribbean has seen a sharp decrease in Green sea turtles and thus a loss of productivity in commercially fished species.6
“All parts of an ecosystem are important, if you lose one, the rest will eventually follow.” -Sea Turtle Conservancy7
Dune Protection and Prevention of Beach Erosion
Beaches and dunes do not get a lot of nutrients because sand doesn’t hold them. However, all of the sea turtle nests, eggs, and hatchlings don’t make it to the sea, leaving valuable nutrients behind, such as nitrogen, phosphorus, and potassium, that allow the dunes to thrive. Even the eggshells from hatched eggs provide some nutrients. This is called nutrient cycling. “Dune vegetation is able to grow and become stronger with the presence of nutrients from turtle eggs. As the dune vegetation grows stronger and healthier, the health of the entire beach/dune ecosystem becomes better. Stronger vegetation and root systems helps to hold the sand in the dunes and helps protect the beach from erosion.”8 But as sea turtles decline, nests decline, and the beaches start eroding.
Additionally, sea turtle eggs, shells, and even hatchlings provide food for other species, which then redistribute the nutrients through their feces. Those nutrients also feed the vegetation that provides stabilization to the dunes.

Coral Reef Development
Hawksbill Sea Turtles, which eat a lot of sea sponges, help protect the coral reefs. “Sponges compete aggressively for space with reef-building corals. By removing sponges from reefs, hawksbills allow other species, such as coral, to colonize and grow.” Without sea turtles, sponges could start to dominate reef communities and limit the growth of corals, and altering the entire coral ecosystem.9
“These amazing creatures are endangered by human interactions, both intentional and unintentional: fishing lines, nets, boat hulls, propellers, and plastic debris, which the turtles mistake for jellyfish and ingest.” -Joel Sartore10

What You Can Do
There are so many things you can do to help protect sea turtles! Here’s a quick list, but you can check out my article “Sea Turtles are Endangered” for detailed information.
Avoid plastic bags. This is a big one because turtles, especially leatherbacks, mistake floating plastic shopping bags for jellyfish, and ingesting bags kills them.
Stop using disposable plastic straws; decline them at restaurants. If you really must have one, carry a metal or glass straw with you.
Keep beaches clean. Litter on beaches prevents hatchlings from reaching the sea.
Turn off the lights.
Use coral reef-friendly sunscreen.
Buy sustainable seafood.
Do your part to slow climate change.
Reduce the chemicals you use in your yard and dispose of others properly through the hazardous waste collection in your area.
Don’t buy products made from real turtle shells.
Make turtle cookies. I know that sounds funny, but if you have children, cookies are a great conversation starter. Even coworkers would give you a few minutes of listening while enjoying them.
Educate others. Try the cookie trick.
Stop releasing helium balloons.
Recycle, or better yet, don’t buy plastic as much as possible.

Adopt-A-Turtle!
There are numerous programs that offer sea turtle nest “adoption” for donation. You can do a quick internet search to find one. I adopt a loggerhead sea turtle nest annually through the Coastal Discovery Museum on Hilton Head Island. For my donation, I receive a certificate, a car sticker, and regular email updates about the general nesting season, and information about the specific nest I’ve sponsored. The funds support their educational programs “which inspire people to care for the Lowcountry and all the plants, animals, and people who call this place home.”11

In my recent post about my trip to Hilton Head Island and its environmental consciousness, I mentioned that the beaches are really clean and well maintained. Even with their efforts, I still picked up about 300 pieces of trash during my week there. Of course, I logged these into my Litterati app (also see my post on Litterati).
I thought I could put the images of my trash to good use, to show people how they can prevent beach and ocean pollution!
I bet you already know a lot of this. But if you share this post, it might enlighten others who will then use preventative measures. And then the world can be a less polluted place!
“Worldwide, 73 percent of beach litter is plastic.” -National Geographic1
Common Types of Beach Trash
I noticed that the same types of trash commonly appear on beaches all over the country. So I’ve divided this post into sections based on the common types of trash I’ve found.
Plastic water bottle almost in the surf.
Plastic drink bottles and caps
These are the most common items I pick up EVERYWHERE, and not just on beaches. Our love affair with drinks in single-use disposable plastic bottles and cups (I’m including styrofoam in this classification because styrofoam is chemically a plastic) is completely out of control. I even picked a red Solo cup that I used to collect cigarette butts and microplastics! Here’s just a few images of the many single-use disposable drink items I picked up:
What can you do?
Buy a reusable drink container (or two) and use that for all your liquid refreshments. I have two: a Kleen Kanteen for water; and a Hydroflask coffee cup. They handle pretty much everything.
If you must buy a beverage, please dispose of it properly.
Food and snack wrappers
I find this type of litter on the beach (and everywhere else) very often. This includes food wrappers, containers, zipper bags, etc. Below is an image of a washed-up cannonball jellyfish next to the plastic lid of a cylindric chip container.
Plastic lid next to a washed-up jellyfish.
Here are some additional examples of food and snack wrappers:

What can you do?
Follow the saying, “Leave it cleaner than you found it.” Or “carry in, carry out.” Don’t lose track of your trash and disposables. Put them inside of your beach bag until you can find a proper trash can. You can also consume less prepackaged food, which will be better for your health as well.
Beach Toys
This is one item that is particular to beaches but so easily preventable. Children scatter and lose their things easily, and almost all beach toys are made of plastic. When these items are left on the beach, they go straight into the ocean during high tide.
You can see how easily small toys are overlooked in the next image. Can you guess what that is?
If you guessed a toy car, you’ve got a good eye!
Here are some other examples of left behind or broken toys:
There were so many abandoned toys on the beach. We weren’t trying to steal toys, I promise! We picked these up as the sun was setting to prevent them from being washed into the ocean at high tide. We donated all but one item to the thrift store.
We found this and my son named it “Mr. Boat.” It’s the only toy we kept – the rest we donated.
In particular, we found multiple plastic bucket straps, as they are not usually permanently affixed. These are easily forgotten about but this cheap plastic will make it into the ocean by the next morning.
There are a few brands, such as Green Toys, that features a rope strap that is not easily removed. The bucket is even made of recycled plastic. It’s the one we own and play with year-round.
What about the packaging for all of those beach toys?
A plastic net bag that the plastic beach toys were sold in, from American Plastic Toys Inc.
Below are images of a discarded boogie board left at a wash station near the beach. I’d seen these little styrofoam balls lining parts of the beach and I couldn’t figure out what they were from. I did not manage to get a good photo of them. Once I found this broken board and looked at it closely, I could see that these are cheap boards are simply nylon or polyester fabric (fabrics made from plastics) over styrofoam. You could not make a worse product for the beach – a product meant to be used in the water that is made of cheap materials and not meant to last more than one vacation – WOW.
Please don’t buy these. This one made it into a proper trash can, but how many end up in the ocean?
What about the dog’s toys? These can be easily lost. And yes, they are made of plastics and other synthetics.
What can you do?
The best thing you can do is to not leave beach toys behind, obviously. The best way to keep track of your children’s toys is simply to own less of them. Perhaps just one bucket and one shovel, for example. In general, kids don’t need many toys when playing outdoors to stay entertained and engaged. Besides the sand and water, the beach offers so many shells, sticks, seaweed and other washed up items that kids are curious about and love to experiment with.
Place broken toys in your beach bag immediately so that it doesn’t get left behind.
As for dog toys, how about throwing a stick for Fido instead of a ball or plastic Frisbee?
Items related to smoking
This is another common item I find everywhere and not just at the beach. Cigarette butts are made of synthetic materials that do not biodegrade. Plastic lighters are found in the stomach of birds and marine animals. Honestly, I used to smoke a long time ago and I sometimes threw cigarette butts on the ground. I had no idea how bad they were for the environment. I pick them up regularly now as part of my Litterati mission, as I feel like I owe the environment for this terrible habit I used to have.
I gathered dozens of cigarette butts and several lighters on the beach, here are a few examples:
I also picked up plastic tips from Swisher Sweets, which if you’re not familiar, are inexpensive flavored tip cigarillos.
What can you do?
Don’t smoke! But if you do, can you please discard your waste properly?
Straws
Aren’t straws like so last year?
No, not really. Not yet. Despite straw bans in different parts of the world.
Everywhere we went in Hilton Head served straws, sometimes automatically in the drink. I’m not criticizing the Island for this, because it happens in my town too. But I hope all eateries eventually end this practice. The exception was the Watusi Cafe on Pope Avenue, which served paper straws – thank you!!!
Straws are everywhere!
What can you do?
Ask the server to not give you a straw before he or she brings your drink. I used to decline the straws when the server would set them down on the table, but since so many places automatically put them in the drink I try to cut them off at the pass. Once that straw is opened and in a drink, it doesn’t matter whether or not I use it – it will now be trashed.
I don’t use a straw very often anymore, but if I need one, I have my Final Straw.
Plastic Bags
I still found a couple of plastic bags on the beach despite the town’s ban on plastic bags!
What can you do?
Decline plastic bags no matter where you live! Bring your own cloth bag.
If you don’t have a bag, can you carry your items without one? I can’t tell you how many times I’ve stopped at a store and purchased one item that the cashier bagged. I don’t need a bag for one item! Give them the bag back right away and say thanks but no thanks!
Many stores do have a paper bag option if you ask for one. If not, they likely have an empty box readily available that you can put your purchases in.
Beach tent/umbrella parts
Many people bring their own beach tents and umbrellas to the beach, but there is sometimes waste associated with those items. Below you can see where I found a plastic tent stake accidentally left behind and a zip tie of which I found several. The last image is of a full plastic water bottle tied to a nylon string. I found this buried in the sand but the string was sticking out. Once I pulled it out, it was obvious that this was most likely used as a weight to hold something down. Clever – but forgotten, an immediate pollutant – this would’ve been in the ocean after high tide.
What can you do?
Collect all of the parts to your tents and umbrellas, even if it’s trash. Double check before you leave that you haven’t forgotten anything.
Everyday Non-Beach items
I find many items on the beach that are not necessarily beach items but items that people use daily. These items include wet wipes or baby wipes (most often not made of anything biodegradable even if the packaging makes that claim); dryer sheets; plastic dental picks; cellophane; condom wrappers; and even a bullet casing (pictured below).
Wet wipe or baby wipeWet wipe or baby wipeDryer sheetBullet Casing
The most surprising things I’ve found on a beach were plastic tampon applicators in the Gulf of Mexico. At first, I thought, there’s no way someone changed their tampon on the beach! But I found not just one, but multiple of these and I’ve also since found them along the Tennessee River. It dawned on me that these items were not left behind by careless beach-goers, but more likely washed up from trash and from sewage disposal that made it into the ocean. It turns out they are colloquially known as “beach whistles” among litter collectors.
“Beach whistle,” or tampon applicator
What can you do?
In general, the best thing you can do is cut down on disposable items and especially single-use disposable plastic items. Even if you’re not leaving these items on the beach, they’re making it onto the beaches and the items are only a portion of what’s washed up from the ocean. Meaning, there’s way more in the ocean.
The answer is to not use disposable items. It sounds difficult, but it can be done. Just work on solving one problem at a time – that’s what I’m doing and sharing with you on this blog!
Thanks for reading, please subscribe in the box above. Love your beaches and ocean. And keep being the change!

There is a coalition of aquariums across the United States that are striving to reduce the use of plastic straws. The coalition is called the Aquarium Conservation Partnership (ACP) and is a collaboration of 22 public aquariums in 17 states, including the Tennessee Aquarium. They are “committed to advancing conservation of the world’s ocean, lakes, and rivers through consumer engagement, business leadership and policy changes.”1
Aquariums are awesome and full of wonder and thousands of children go through them daily. So they are poised to be leaders in positive change, and this is a great example of that! One of the things they’re doing is asking restaurants and others in the hospitality industry to reduce the use of straws by only giving them out upon request, instead of automatically. They’re also asking individuals to sign a pledge to stop using plastic straws.

What’s wrong with plastic straws?
First, the sheer amount of them! Just like with all single-use disposable plastic products, it’s the over-consumption of them. Think 500 million plastic straws per day. That’s more than one straw per person per day in the United States. Our consumption has gone way overboard and has created a waste stream that is too large for us to keep up with! Second, they are not recyclable at all.
Don’t feel guilty about having used plastic straws. Just please refuse plastic straws – START TODAY. Politely refuse those plastic straws – if everyone refuses just one straw per day, we’ll more than cut our usage in half!

I threw my disposables into the trash/recycling receptacle like I’m supposed to, how are they ending up in the rivers and ocean?
One of the critical issues with all the media about single-use disposable plastics is that the biggest question is often not answered: How does the plastic end up in the ocean in the first place?
Most people assume that once they’ve placed their disposables into a receptacle, those disposables go to the proper facility. What people don’t know is that many items don’t make it to the recycling facility or landfill. Since that’s out of our control, it seems impossible to do anything about it. But it’s not impossible by any means. The best way to guarantee that your single-use disposable plastics don’t end up in the ocean is…
To just not use them! Refuse them. Find an alternative. Then you do have control. We have the power to be the change.
So back to the question – how are plastics ending up in the rivers and ocean?
There are so many causes! Spillage from recycling that has been transported across the ocean for years to Asia; plastic products shipped across the ocean to the U.S. have spilled from ships; the fishing industry regularly dumps their trash into the ocean; trash and litter get blown or washed into storm drains and rivers that then feed into the ocean; illegal dumping; beach trash; river pollution; microbeads washing down drains; and debris from natural disasters and floods. Plastic bags are picked up by the wind and blown into waterways that flow into the ocean.

Ok, so what steps can I take?
First, let’s support the Aquarium Conservation Partnership. You can do this by signing the pledge (linked under Additional Resources below).
Second, refuse. Just say no thank you. To all single-use disposable plastics. Because recycling is not the answer. Only about 9% of our plastics get recycled. That means 91% is not recycled!
Third, if you must have something commonly produced as a single-use disposable plastic, like a straw, please buy a reusable one. Paper disposables and supposedly biodegradable straws are a better option, but it’s still going to be thrown away after one use. Try a stainless steel straw, glass straw, or bamboo straw.
Fourth, tell others! Tell your friends, your co-workers, your favorite restaurant, the local coffee shop, and your local school. So many to tell!
Fifth, participate in trash clean-up efforts. Join the Litterati. Maybe you’ll keep some of the trash you pick up from entering the ocean.

Last, stop supporting businesses that just won’t get on board. If consumers are asking businesses they patronize to stop using certain items, such as single-use disposable plastics, the consumer also has the power to not patronize that business. If consumers refuse to spend money at a business because that business does not do or provide what consumers want, then that business will be forced to change if they want to maintain profitability.
Final Thoughts
Collectively, have the power to create change just by modeling the best behavior. Refuse that straw. Be polite, of course. But just say no. You might influence someone else to refuse straws too. If everyone starts refusing straws, businesses won’t have the need to order as many. Then the plastic straw manufacturers will have to produce less. And then less will end up in landfills, in nature, and in the oceans. Carry a reusable stainless steel straw with you. Be the change! And as always, thanks for reading.
Sea turtles are endangered, which is probably not news to you, but you may not know the reasons they are endangered. They are keystone species, meaning they play a crucial role in the way an ecosystem functions. According to Oceana.org,sea turtles “play an important role in ocean ecosystems by maintaining healthy seagrass beds and coral reefs, providing key habitat for other marine life, helping to balance marine food webs and facilitating nutrient cycling from water to land.”1 I want to help people understand what we can do right NOW to help.
Sea turtles have been on the Earth for at least 110 million years, and now human activities are to blame for their decline and endangerment. All 7 sea turtle species are vulnerable, threatened, or endangered due to human behaviors and activities.2 Following are the biggest threats:
Entanglement and Bycatch
Coastal development
Artificial Light
Coastal Armoring
Plastics
Beach (and Ocean) Litter
Ocean pollution
Global warming
Poaching and illegal trade of eggs, meat, and shells
Turtle Shell Trade
Let’s examine each of those further.

Entanglement and Bycatch
Entanglement is exactly what it sounds like, that is, entanglement in fishing nets and gear. Up to 40% of all animals caught in fisheries are discarded as waste. Bycatch refers to animals that were not the target catch – for example, dolphins getting caught in tuna nets. “Despite ‘Dolphin Safe Tuna’ labeling, approximately 1000 dolphins die as bycatch in the Eastern Tropical Pacific tuna fishery each year,” according to seeturtles.org. The World Wildlife Fund explains that “modern fishing gear, often undetectable by sight and extremely strong, is very efficient at catching the desired fish species—as well as anything else in its path.”3 Most often the animals die.
There are some protections for certain species, such as the dolphins mentioned above, but it is not a perfect system and the whole industry needs to find more solutions. “Each year hundreds of thousands of adult and immature sea turtles are accidentally captured in fisheries ranging from highly mechanized operations to small-scale fishermen around the world.”4 Companies that use devices called Turtle Excluder Devices (TEDs) are following regulations and best practices.
What can you do? Try to only buy responsibly caught seafood. Inform and encourage your family and friends to purchase seafood only from responsible fisheries.

Coastal Development
Coastal development is exactly what it sounds like. “Half of the world’s population lives on or within 100 miles of a coastline and this number will likely increase dramatically in the next decade.”5 Human presence deters turtles from nesting where they would normally. Additionally, humans create pollution and waste – whether it’s litter or waste-water runoff, light pollution, or danger from vehicles driving on beaches.
What can you do? Whether you’re just vacationing at a beach or residing there, educate yourself about habitats in that area. First, follow the scout rule of “leave it cleaner than you found it.” That means leaving no trace! And pick up after other people too, because it’s the right thing to do.
Second, always limit light on beaches (this will allow you to see the stars, too!). Are there conservation efforts ongoing? Are there laws prohibiting certain practices to protect turtles? If so, make sure you follow the laws or best practices. You’ll be making a difference. If you’re going to live coastal, this is even more important – search the internet for where you live so that you can do the right thing, and be the change.
No laws or conservation efforts where you live? How about starting those efforts? You can partner with a local aquarium; lobby city or town council to get signs posted near the beach access points; even host a local seminar at the library and invite residents!
Turn Off The Lights
As mentioned above, artificial light from human presence is a big problem for turtle nests. Sea turtles depend on a dark and quiet beach for nesting. If there is too much light, turtles will choose a less optimal nest site, which reduces the chances of the baby sea turtles surviving. Also, hatchlings have an instinct that leads them in the brightest direction which is normally moonlight reflecting off of the ocean. Excess lighting from the nearby buildings and streets draws hatchlings toward land instead, where they will likely die from predators, humans, or even swimming pools.
What can you do? Eliminate light whether you’re a property or homeowner, tourist, or beach walker. Make your property low light and encourage others to do the same – especially during nesting season!
If you’re walking on the beach at night, don’t use flashlights and phone lights during nesting season. Download a red flashlight app if you must have some light. If you live in a beach-front residence, turn your lights off. I’ve listed an article about turtle-friendly lighting under Additional Resources.
Here is a video from the Sea Turtle Conservancy about how to eliminate artificial beach lighting:
Coastal Armoring
Beaches are beautiful and the place many people want to be, myself included, someday. Coastal areas are prime real estate and many beaches in the world have been heavily developed. Coastal armoring refers to sea walls and similar structures that protect real estate property, but they are harmful to sea turtles. The Sea Turtle Conservancy explains: “Sea walls directly threaten sea turtles by reducing or degrading suitable nesting habitat. They block turtles from reaching the upper portion of the beach, causing turtles to nest in less-than-optimal nesting areas lower on the beach where their nests are more susceptible to wave action and more likely to be covered with water.”6
What can you do?If you’re a developer or building a home for yourself, please always first check with local legislation. Many coastal places in the United States already have existing legislation sometimes called Coastal Zone Protection, Dune Protection, or Dune Management. You can search the internet for the area you are residing in or visiting for information. If your area of interest has no protections or current legislation, how about proposing it to the local council or government? Please don’t build anything without first doing careful research – there are a ton of organizations out there that can advise or point you in the right direction. Do your homework, and the turtles (as well as other wildlife, humans, and the environment) will reap the benefits. Be the change.
Plastics
Well, this topic is what my blog is all about: plastics and other human-made waste. Hundreds of thousands of marine animals and fish, as well as over 1 million seabirds, die each year from ocean pollution and ingestion or entanglement in marine debris. This includes turtles. Most plastic waste reaches the ocean via rivers, and up to 80% of this waste comes from landfill-bound trash. How does that happen!?!? I’ll get into that in another post.
Plastic bags are a huge factor when it comes to sea turtles. Why? Because turtles eat plastic bags. They mistake them for jellyfish. Many species of turtles do not have taste buds, in case you’re wondering why they can’t tell by taste. See the videos below. The first one shows you the difference between a jellyfish and a plastic bag floating in the water.
The next video shows you turtles eating a jellyfish, to give you visual context.
What can you do? My number one recommendation for the first thing you should change to make a difference: use reusable bags only, and don’t accept plastic bags from anywhere! Getting rid of plastic bags does and will keep making a big difference on so many fronts, so I can’t stress this enough!
After plastic bags, start eliminating all plastics from your life, especially single-use disposable plastics. Recycle, or better yet, don’t buy plastic as much as possible. “Over 1 million marine animals (including mammals, fish, sharks, turtles, and birds) are killed each year due to plastic debris in the ocean. More than 80% of this plastic comes from land. It washes out from our beaches and streets. Plastic travels through storm drains into streams and rivers. It flies away from landfills into our seas. As a result, thousands of sea turtles accidentally swallow these plastics, mistaking them for food.”7
Plastic bag from Walmart lying on the beach. I photographed this bag myself and disposed of it. At high tide that afternoon, it would’ve washed into the ocean and potentially harmed a sea turtle.
Stop using disposable plastic straws and decline them at restaurants. Besides plastic breaking down into smaller pieces and polluting beaches and the ocean, these get stuck in turtles’ nostrils and airways. You don’t need a straw to drink most beverages. If you really must have one, carry a metal or glass straw with you.
Don’t release helium balloons! They burst and fall to the Earth or the sea, and sea turtles mistakenly eat the balloons and die. Or stop using balloons altogether.

Beach (and Ocean) Litter
Besides trash flowing into the ocean, litter on beaches prevents hatchlings from reaching the sea.
What can you do? Keep beaches clean. Don’t leave behind litter or beach toys when visiting the beach. I try to leave the beach a little cleaner than I found it, picking up trash that is about to wash into the sea with the changing tides. Participate in beach clean-up events or clean up with your friends or family.
Use coral reef-friendly sunscreen. Many of your average sunscreens have chemicals in them that are not only harmful to the ocean, but also to the human body. Look at the Environmental Working Group’s (EWG) Sunscreen Guide (see Additional Resources for the link).
Ocean Pollution
Although trash and plastics are one component, there are many, many other ways in which human activities pollute the ocean. Waste and by-products, like toxic metals, PCBs, petroleum products, agricultural and industrial runoff of contaminants such as fertilizers, chemicals, nutrients, and untreated waste; are all major problems for ocean and land dwellers. These are also causing major human health problems (many major diseases can be tied to these chemicals – again, another topic for another day). Oil companies are a big contributor to pollution, above and beyond oil spills.
What can you do? Buy less and consume less overall. Reduce how much meat you eat and how many animal products you use, because agriculture creates a lot of waste, methane, and chemicals. These chemicals make it into waterways and then the ocean, which poisons wildlife throughout the food chain. Buying from a farmer’s market locally or even growing your own food can reduce the amount of fertilizer and pesticide chemicals that make it into our water (because smaller farms don’t always use such harsh chemicals, and I doubt you do in your own garden). Reduce the chemicals you use in your yard and dispose of others properly through the hazardous waste collection in your area.
Global Warming
This is a sensitive topic because it is so tied to politics these days. But global warming is real and happening, at an accelerated rate, which means many species will not be able to adapt quickly enough. This means the possible extinction of plants and animals and fish that are necessary to Earth’s balance.
What can you do?Reduce how much you drive. Perhaps try carpooling or using mass transportation. Ride a bike. Buy an electric car. Tell the oil companies to go to hell. Reduce the amount of energy you use. Avoid using fossil fuel energy whenever possible. Eat less meat and reduce your water use. Those are the first steps – start there!

Poaching and Illegal Trade
In some countries, turtle meat and turtle eggs are a food source; in others, turtle eggs are collected by people for income in order to feed their families. Sometimes during nesting season, hunters will watch for nesting females. Once located, they will wait until the female turtle has finished laying her eggs, then kill her for the meat and take the eggs as well.
What can you do? If you travel, don’t buy food or products that use turtle, as that supports the practice. Organizations and governments are educating tourists and local inhabitants about the endangered turtles around the world. You can help by supporting the causes that protect and monitor sea turtle nests. You can help by spreading the information and helping to educate others about the problems. Participate in eco-tourism!
Turtle Shell Trade
This relates to poaching and illegal trade but is specific in regards to products made from turtle shells, aka tortoiseshell; and is usually specific to the Hawksbill sea turtles. The Sea Turtle Conservancy indicates that “scientists estimate that hawksbill populations have declined by 90 percent during the past 100 years.”8 This has been outlawed by CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) which is an international agreement signed by 173 governments. However, the black market demand for turtle shells is still high.
What can you do? Don’t buy items that might be made from turtle shells or other turtle parts (including skin). Of course, those products likely won’t be labeled “turtle shell” or “hawksbill shell” but if you suspect, just say no and walk away. Unfortunately, the alternative is plastic, which I am trying to eliminate from my life. So be more minimalist and don’t buy either! You’ll remember your trip or vacation without a bunch of souvenirs anyway. Here’s a handy infographic put out by Travel For Wildlife to help you avoid turtle shell products:
They also made this very informative video, so please share it on social media with your friends and family!
You can join me in signing the pledge to avoid turtle shells with the See Turtles Organization9. They, too, have wonderful resources about how to identify real turtle shell vs. fake.10 Again, maybe just don’t buy either – it’s not worth the risk!
Adopt-A-Sea Turtle!
You can symbolically adopt a sea turtle or a sea turtle nest. There are many of these, you’ll find many just by searching online but look for a reliable organization. Most of the programs fund education about sea turtle nests, protect nests, and/or track sea turtles.
