MCQs on Overfishing. Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish in time, resulting in those species either becoming depleted or very underpopulated in that given area
Why overfishing is a problem?
It can change the size of fish remaining, as well as how they reproduce and the speed at which they mature. When too many fish are taken out of the ocean it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals.
What will happen if overfishing continues?
If overfishing continues, more species will be driven to extinction and aquatic ecosystems will collapse.
Why is overfishing such a complex environmental issue?
Worldwide about 90% of the stocks of large predatory fish stocks are already gone. In the real world all this comes down to two serious problems. We are losing species as well as entire ecosystems. As a result the overall ecological unity of our oceans are under stress and at risk of collapse.
