Well, there are so many reasons that are hampering marine life. Among them, overfishing is holding the top position. Due to overfishing, the shark population is being hampered. Overfishing is actually increasing the potential risks of various species. If we talk more specifically, it is actually creating a problem for the predators that are large in size. Shark populations on the decline and overfishing are inextricably related to each other. According to a survey, the shark population has already been declined by almost 70% since 1970. On the other side, there is an almost 19 fold increase in the fishing pressure.
People have been studying fossils for a long period of time and you might be surprised to know that sharks are older than dinosaurs. Yes, there are more than 1000 species of rays and sharks and some of them are older than dinosaurs. Moreover, every year, new species have been discovered. Sharks have been considered as one of the most dangerous predators. Actually, they are playing a very important role in the marine ecosystem. Go through the below-mentioned points to know more about them:
Making Ocean More Elastic To The Overall Climate Change
Well, you will be surprised to know that sharks are playing an important role in the processing of making the oceans more elastic to the overall climate change. Yes, you have got it right. Tiger sharks play the role of crowd controllers. It does not allow the dugongs and turtles to overgraze. If they do not graze at the same spot for a long period of time, you will see abundance in the seagrass. Seagrass has the potentiality to capture carbon 35 times faster than the rainforests from the atmosphere.
Helps To Grow Phytoplankton
Well, talking about the oxygen supply on our planet, phytoplankton plays a very important role. Deep-diving and large sharks play a very important role in the process of growing phytoplankton. They dive down and when they come to the water surface, they actually bring various important nutrients. Those elements help the phytoplankton to grow.
As of now, you have understood that sharks play a very essential role in the marine ecosystem. Now, overfishing is actually decreasing the number of sharks over the course of time. They are irreplaceable and therefore, it has become a major concern in the 21st century. In order to improve resilience, we must work on the process of restoring sharks and rays. Otherwise, we will have to face deadly outcomes in the future.
