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.

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!

If you read my post about my family’s weekend trip to Hilton Head Island last fall, then you already know how much we love the island. We recently returned from a week-long trip there, and inspiration was all around! Besides the natural beauty of the island and the gorgeous beaches, there are many environmentally conscious things I appreciate about Hilton Head Island.

Plastic bag ban in Beaufort County, South Carolina
They implemented a plastic bag ban last fall, and I am here to tell you that from a tourist’s perspective, businesses have not been hurt by this. People were shopping in all the shops and supermarkets and the plastic bag ban did not seem to deter anyone from spending money. I have not found any studies on the result of this ban in the last 8 months, but I imagine the impact has been huge!
Unfortunately, I did find one article indicating that Target and Walmart are using supposedly “reusable” plastic bags. But since they are made of the same material as regular plastic bags, they defeat the whole purpose. I did not happen to shop at either store while there so I did not witness this first hand. As the article noted, that is disappointing.
At the other shops and stores I visited, I personally received only paper bags when I didn’t have my cloth bags with me. I love it! Can’t we do this everywhere?
Gorgeous dunes on HHI.
Wildlife
There’s a lot of cherished and protected wildlife on the island. We saw all types of birds, including pelicans – my favorite! We saw dolphins, tons of fish, and several types of crabs. There are also bald eagles, alligators, and turtles living on the island but we didn’t personally get to see those this time. The local government’s website educates on sustainable living, the types of local wildlife, native plants, biodiversity, ecosystems, and how everyone can help protect those things.

Sea Turtle Conservation Efforts
Although we did not see sea turtles this trip, we saw at least 7 cordoned loggerhead sea turtle nest areas. They were marked with orange signs provided by the South Carolina Department of Natural Resources, which alerts the public about the protection of this endangered species through federal and state laws.

Many Atlantic coast towns have laws, regulations, and organizations to protect sea turtle nests. On Hilton Head Island, lights on buildings and hotels cannot shine in the direction of the beach. People are only permitted to use red or “turtle-safe” flashlights on the beach between 10 p.m. and 6 a.m. between May and October. They have a volunteer organization that patrols, monitors, and reports on sea turtle nests. They also clean up beach litter and plastics.
I read this article about a Kemp’s Ridley turtle making a nest on Hilton Head Island, a first-time event for the most endangered of all the sea turtle species! Wow!
The Coastal Discovery Museum has an “Adopt-a-Nest” Program, which not only sponsors the protection of a sea turtle nest but also supports the museum’s educational programs. Of course, this idea excited me so I absolutely adopted a nest while writing this post! They emailed me to let me know that my nest will be the 277th one this year and that they’ll keep me informed on the progress of my adopted nest.
Can I inspire you to adopt a nest as well? Just use the link above!

Coastal Discovery Museum
The Coastal Discovery Museum on the island is a great non-profit and Smithsonian Affiliate, dedicated to educating and protecting the natural resources, history, and ecosystems of the region. Their mission “inspires people to care for the Lowcountry,” through their many programs, exhibits, talks, and tours. What a great organization.
We’ve visited several times in past years but this year we did a Dolphin and Nature Cruise with the museum and really enjoyed it. And yes, we did see dolphins! The museum docent provided a dolphin skull replica and spoke about the anatomy, diet, and lifestyle of the local dolphins. The captain provided a rich tour about the history and nature of the island. Both the captain and museum docent were very knowledgeable and kept the passengers engaged for the entirety of the cruise. They even let each of the kids drive the boat for a few minutes!

Beach Trash
Hilton Head Island’s beaches are very clean and well maintained. And there are both trash and recycling cans up and down the beach. Even so, I still picked up about 300 pieces of trash during my week there. Of course, I logged these through Litterati (see also my post on Litterati). My next post will be about the types of trash I found and what you can do to prevent beach trash and ocean pollution!
Thanks for reading, and please subscribe!
All photographs in this post were taken by me except where otherwise indicated.
Our family loves Hilton Head Island (HHI) for a variety of reasons. First, my husband and I got married there. What drew us there before marriage was the island’s dog-friendliness. But then we discovered some other things about the island, besides its natural beauty, cleanliness, and great restaurants.
There are no billboards or neon signs littering the landscape because ordinances keep signs low and unobtrusive. No building can be taller than the trees. Hilton Head also has a sea turtle protection project. The town requires light structures visible from the beach to be covered or turned off between the hours of 10 pm and 6 am during nesting and hatching season, which spans from May through October.

We’ve taken many trips to HHI, including this past weekend, and we had a wonderful and relaxing time. Of course, we saw beautiful sunsets and sunrises. We witnessed a full rainbow, which was my first time seeing one (see my pitiful attempt at a panoramic image above). We saw a stingray trapped in a tidal pool, which was cool to see up close. We alerted someone who was able to move it back to the ocean. And we saw a ghost crab up close – so cool!

A Clean Beach
I mentioned that Hilton Head Island is very clean, especially compared to other beaches we’ve visited. Since we are a family that cleans up litter and trash, we pay attention. So for a clean beach, here’s some of the trash we picked up and posted on the Litterati app:
Seems like a lot, doesn’t it? It wasn’t compared to other litter pick-ups I’ve seen or been involved with. We found straws which I’ve determined to be the evilest single-use disposable plastic thing in use! We found cigarette butts, pieces of Styrofoam, and microplastics. The image of the bag of trash was from a garbage can that blew over during high winds and the trash scattered. We collected all we could but it was far too windy to try and photograph each piece. The contents of it were mainly single-use disposable drink bottles. We found some beach toys, as we usually do. I promise we didn’t take these from someone! They sat abandoned for a long time, and I didn’t want them to wash out to sea during high tide!
Plastic Bag Ban!
On our last evening, we stopped at the ice cream shop. As I was paying, I saw a sign posted by the register, and I think I startled the clerk with my excited reaction!
Plastic bag ban ordinance! Photo by Marie Cullis.
The Town of Hilton Head Island passed this ordinance in January 2018. It does not ban all plastic bags, such as produce and meat bags; however, it is a huge, progressive step in the right direction. Eating my ice cream, I felt inspired – could I get that ordinance passed in my city? What a huge task that would be…but maybe I could do it.
