Why We Need Sharks

As the apex predators of the oceans, the role of sharks is to keep other marine life in healthy balance and to regulate the oceans.
The prospect of a food chain minus its apex predators may mean the end of the line for many more species.
Sharks have widespread global distribution, are highly migratory and play a vital role in maintaining the health of ocean ecosystems.
Sharks are a critical component in an ecosystem that provides 1/3 of our world with food, produces more oxygen than all the rainforests combined, removes half of the atmosphere’s manmade carbon dioxide (greenhouse gas), and controls our planet’s temperature and weather.
The oceans are the most important ecosystem on the planet, and our best defense against global warming, containing life that absorbs most of the carbon dioxide (global warming gas) that we put into the atmosphere, converting it into a large percentage of the oxygen we breathe.
Sharks play a vital role at the top of the food chain by maintaining balance in the oceans. Destroying shark populations could destroy our oceans and our life support system.
We have already witnessed localized collapses of fisheries and ecosystems due to the removal of sharks, including the scallop fisheries in Chesapeake Bay, the coral reefs in Belize and the cod in New England.
