Happy World Sea Turtle Day! Though these beautiful and important creatures deserve everyone’s attention year-round, I like to honor this day, June 16th, to acknowledge and bring awareness to their plight.
I found this video about sea turtles from the Newport Aquarium in Newport, Kentucky, which my family just visited this past April (2022):
The aquarium had a really great display with a cross-section of how a sea turtle nest looks under the sand:
It is extremely important to protect these nests since hatchlings have a very low chance of survival to adulthood. Here’s a TED-Ed video explaining the struggles hatchlings face:
You can also adopt a sea turtle nest! There are many organizations at every level – global down to local communities – that take donations to protect a nest and educate their communities. I adopt one annually on Hilton Head Island through the Coastal Discovery Museum since that area is special to my family. There seems to be a program near most coastal communities in the United States, so just pick one!

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?
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!
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!

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
Beach (and Ocean) Litter
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 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:
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.
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
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).
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.
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!
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.
