How does illegal fishing affect the environment?

Overfishing can effect a human because .... the fishermen or fisher lady ... have to stay awake all night and day to ... prepare to catch a fish .... this can mean they can get cranky and can smell for days ... because they are too tired to do anything ... they just care about going fishing again.......... THIS IS ALL TRUE BTW. xx

Over fishing affects us by using up all the fish that some need to survive or that we humans just use for different reasons
