What if there were no Sharks? | #aumsum #kids #science #education #children

Firstly, the makers of Shark movies will have to search for a new villain.
Secondly, sharks have been around for more than 400 million years, with no sharks, the natural food chain in the oceans might just completely collapse.
Thirdly, with no sharks around to eat those fishes which eat algae-eating fishes, there will be a drastic decrease in algae-eating fishes. This will lead to an exponential increase in the amount of algae. This algae will cover the coral reefs, not allowing it to photosynthesize. This loss of habitat will lead to mass extinction.
Fourthly, sea creatures which depend on shark's nitrogen rich poo for nourishment will suffer.
On the flip side, surfers as well as people with galeophobia i.e. fear of sharks will be one happy lot.
