most people can't swim
it causes floods and can destroy buildings and can make people drown.
A major reason is that people will cut off their fins for food. That causes the shark to stop swimming. Sharks have to swim or they will drown. The sharks drown and die.
Well it causes a lot of destruction to homes, shelters, buildings and floods drown a lot of living things including people. It also destroys and rips out trees from their roots, and could drown plants.
No oxygen.
People have to be taught to swim. Animals for the most part have the ability to swim instinctively. I believe people have lost some of their instincts as they gained intelligence.
They drown
It causes you to get carried away but I'm not sure if it could drown you...probably especially if you're a poor swimmer
many people drown in america from flooda and storms. we cannot really count how many people have drowned though. sorry
They drown
Thier dorsal fin, I'm not sure why but I do know they will drown and die without it, people catch sharks and cut off their dorsal fin to sell and throw the shark back where they drown.
build a wall around a pool as close as you can so there arent any gaps then they will drown to death :(
umm NO people live on hawaii.
