How Much is Too Much?

Lesson Description:

Overfishing has become a major environmental issue. According to National Geographic, about 90% of large fish in the world’s oceans are gone, compared to the populations in 1950. Put another way, only 10% of large fish remain. And as fish stocks become depleted, fish becomes more valuable, and prices go up, giving fishermen even more incentive to take what little is left. So how can scientists and government officials solve this problem? The answer lies in simple Algebra.
