1- If you see garbage, plastic bags or helium balloons on the beach pick them up and throw them away. Sea Turtles, and other marine life will eat these and die. They do gently encourage people to not even use these products, but they realize this is not an easy task.
2- If you are lucky enough to see sea turtles making their nests on the beach don't bother them. They can actually get spooked and leave the nest without finishing. Don't flash a camera right in their face. Don't be loud. They do offer a turtle walk in Melbourne, FL where you can watch the sea turtles in the nesting process. There are only a few spots left for this year. We will definitely be signing up to do this next year. What a wonderful experience.
3- Use LED lights if you own a hotel or business on one of the beaches that the sea turtles nest on.
