1.The sloppy tourists throw their garbage in the water instead of trash cans so the sea turtles try to eat it thinking that the plastic bags are jellyfish. The thing is that the garbage is suffocating them so they can't breathe.
2.Volunteering groups can help clean the environment or try to take the plastic bags and garbage from the water.
3.There should be some laws that forbid the throwing of garbage elsewhere than in the trash cans.
