How do humans affect overfishing?
Many people rely on fishing as their means of income. With the fish population decreasing, fishing jobs will become scarcer causing people to lose jobs and having to find other work. Those who frequently eat fish from non-sustainable resources are also contributing to the overfishing effects we see today.
Where is overfishing the biggest problem?
Our major finding was that overfishing is the most important factor affecting Mediterranean underwater ecosystems, more than pollution, invasive species, or climate change. Taking fish out of the sea in massive quantities is what changes the underwater landscape the most. More than anything else. Period.19
