Sometimes, babies head towards the artificial light (human residential areas near the coast) instead of heading towards the sea. They perhaps consider it as setting sun's light. These babies die soon. Many times, when sea turtles come to the surface of the ocean for breathing, they get hit by boats. They also get tangled in fishing nets and drown. Different types of turtles are killed by human beings during trawling. Fishing nets should have turtle-exclude devices which allow the turtles to escape when caught.
