Sharks are apex predators. They help to regulate and maintain the health of the ocean by picking off the dead, dying, sick and weak to prevent disease in the ocean. Their presence in ecosystems alone helps to maintain balance. For example, they help maintain balance of phytoplankton and scare off predators. Phytoplankton that is balanced in the ocean absorbs carbon from the atmosphere and helps to clean the air we breathe. That also goes for coral reefs acting as huge carbon sinks and sharks regulate all of that. The overfishing of such a vital species is catastrophic to the health of the ocean and unfortunately, the fear of sharks has caused many to turn a blind eye. It's important to note that there is SO much learning to do, resources to explore, etc. but these are some ways to help and gain knowledge through my eyes in an easily digestible way. 

Sharks are being killed in the millions each year & they are vital to the health of the ocean.
