Due to climate change, the concern of experts is increasing. This change is not only increasing the temperature, but the number of fauna is also falling rapidly. A similar study has been expressed in a study published on Wednesday in Journal Nature. It has been told that the number of sea sharks is decreasing rapidly at the global level.
The study says that between 1970 and 2018, the number of sharks has fallen by more than 70 percent. With this, the risk of extinction of 24 out of 31 species of shark and rage has increased. Scalloped Hammerhead Sharks and Great Hammerhead Sharks are becoming critically endangered. “The last 50 years have been devastating for shark populations globally,” said Nathan Paikoru, a biologist at Canada’s Siman Fraser University and co-author of the study.
Shark is also being hunted
Sometimes sharks are also hunted deliberately while catching fish and other sea creatures. The number of vehicles known to capture these creatures in the open seas has also increased. Climate change and increasing pollution of organisms like sharks have made life more difficult than before.
Necessary to balance ecosystem
Stuart Pym, an ecologist at Duke University, says, “When you remove large animals from the sea, it affects the entire food chain of the sea.” Sharks are like lions, cheetahs and bears in the sea world. They are necessary to maintain balance in the entire ecosystem. However PIM was not included in this study.
