Make shark culling illegal

Shark culling has significantly decreased the population of shark numbers in our oceans. Since the beginning on 1970, shark populations have decreased by a dyer 82%.
Sharks are the top of the food chain, once they die, large fish become the top of the food chain.
The large fish feed on small fish so once the small fish get eaten by the big fish the big fish will starve and die.
Resulting in no fish in the ocean:
No fish in the ocean results in algae growing out of control, smothering sea plants and causing them to be unable to survive.

Extinct.

Once everything else dies, crabs and other decomposers will run out of decomposing matter causing them to starve and die. Meaning that everything in the ocean will become extinct and no life will live in it other than algae and bacteria.
This process would take hundreds of years to complete but facts are that it WILL happen if all sharks become extinct.

THE FACTS ARE THIS:
Humans CAN NOT act against sharks.
It's simple.
When we go into the ocean, it is SHARK TERRITORY! That is their home and we enter at our own risk!
RESPECT THE OCEAN!
There is no such thing as a 'rouge shark' as the media likes to call them after they attack, sharks are designed to see prey, hunt it, eat it, and survive another day.

This may seem far fetched, however it isn't, if people don't act now to stop the unnecessary killing of sharks, generations to come will only suffer.
