The world may never know precisely how many sharks are in the ocean, or exactly how many are killed each year by fishermen. What is known, from many of different types of experiments, is that the population of many different types of sharks are decreasing at very alarming rates. Perhaps more importantly, the people of the world know that what they are doing to the sharks is wrong and that they should stop the killing so that the sharks can repopulate to help the ecosystem. Sharks are endangered because of people of the world not because of things they cannot
