Saving Sharks, Saving Us

What sharkhunters, and people in general, don't understand is that we NEED sharks. The risk we are taking by removing a large number of predators from the ocean is high and dangerous. 66% of Earth is covered in water 80% of life is found in the oceans. The ocean is the most important ecosystem as it regulates climate and feeds much of the planet. Sharks have been one of the most abundant predators on the planet as they are a necessary presence in the oceans, and they help to maintain a framework for the populations below them that include phytoplankton (tiny aquatic plants that consume more carbon dioxide, the global warming gas, than anything else on earth). The plankton convert the carbon dioxide to oxygen which provides 70% of the oxygen we breath on land. If there are no sharks to prey, the plankton feeders could grow out of control and consume more plankton than necessary, taking away what we depend on for survival.
If we kill continue to kill sharks then we continue to destroy all food chains of marine ecosystems. Oceans are the life-support system for the planet. In the past, when oceans have changed, the world has changed.

The killing of sharks has been called "the biggest ecological time bomb we are going to face soon."

Shark species are declining, there are fewer and fewer everyday; this is no natural phenomenon, it is overfishing.
SHARKS SURVIVE, OCEANS SURVIVE, HUMANS SURVIVE
