Figure-4 shows that rate at which the demand for fish has been met has slowed over the last 30 years due to the increase in the worlds population. The amount of fish per person has gone up, but the amount of that provide for by wild catch has remained constant over the years. The amount of fish per person has been allowed to increase due to the increased supply of fish provided by aquaculture. Because the population is still increasing, the world's demand for fish is increasing. If the amount of fish pulled from the ocean remains constant, as it has over the last 20 or so years, the amount of fish per person will begin to drop if which will cause people to starve, economies to collapse, and our fish stocks to be depleted.
