By allowing the full extinction of sharks, we are in fact bringing undesired consequences to our primary food and air source. It is important to keep the ecosystem healthy in order to ensure our own survival. Seas play an important role in the whole ecosystem as they provide us with food and oxygen, remove greenhouse gas as well as maintain the temperature and weather of the planet. Being on the extreme top of the food chain, sharks have been playing an extremely important role in ensuring the health of the sea ecosystem for the past 450 million years.
