Theory:

Sea turtles are among the many wonderful creatures we share this planet with. They have survived natural dangers for millions of years. But, sadly, human activities during the last few decades have put them in grave danger. There are many factors that threaten their survival. People hunt them for their meat or collect their eggs. Sometimes they are accidentally trapped in the nests of motorboats. Problems like pollution, dumping of plastics into the ocean and construction activities on nesting beaches also hurt their survival. Only by systematically tackling these problems, and removing these threats, can we ensure that sea turtles will continue to exist in the years to come.
