If sharks became extinct, there would be ecological repercussions, such as small animal extinction, algae overgrowth and coral reef death. Sharks are a crucial part of the marine ecosystem and are necessary for the world's oceans to operate.
The ocean is considered by many to be the "most important ecosystem," as the Sea Shepherd Conservation Society explains, and it is up to humans to take the necessary steps to halt shark extinction. Sharks are becoming extinct due to overfishing and the degradation of the ocean waters that they live in. Sharks are not threats to the human population and kill approximately one human per year, though humans kill approximately 100 million sharks each year, states CNN.
