Sharks populations are declining worldwide. This is (somewhat) common knowledge. What i think escapes most people is how important sharks are to the marine ecosystem.

In all marine food chains where there are sharks, they are at the top. Now, you remove the shark, you’re cutting of the head. There would be nothing to regulate (except human overfishing, but that’s another matter for another post) fish which feed on phytoplankton down at the bottom off the food chain. This phytoplankton creates something like 70% of atmospheric oxygen through photosynthesis. 

It’s amazing how sharks, who managed to survive all 5 major extinction events in this planets history are now finally disappearing. Who needs asteroids and massive volcanic eruptions when we have ourselves?
