OVERFISHING: Bottom trawling is when people drag big nets from the bottom of the ocean and collect schools of fish. Bottom trawling leads to overfishing because they're killing too many fish. Bottom trawling is like taking a bulldozer and trying to chase a couple of squirrels out of a hunting area. Banning bottom trawling helps the fish recover.
POLLUTION: Pollution poisons the water. One hundred thousand fish die from pollution every year. The fish's environment is destroyed due to pollution. If pollution is bad for humans, it's bad for the fish.
REPRODUCTION: Overfishing and pollution affects the ability to reproduce the next generation of fish. The reason why is the female fish population is decreased. The male fish that guard the eggs can't do their jobs. The eggs spawned in the polluted water will be very unhealthy.
