What is overexploitation of fish?
Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish, resulting in those species becoming underpopulated in that area.
What does overexploitation the oceans threaten?
Overfishing is closely tied to bycatch—the capture of unwanted sea life while fishing for a different species. This, too, is a serious marine threat that causes the needless loss of billions of fish, along with hundreds of thousands of sea turtles and cetaceans.
How is exploited oceans caused?
The impact of human behavior on the ocean is vast. We dump everything in our oceans, including plastic bags and other plastic debris, garbage, military munitions and toxic chemicals, crude oil, sewage and nuclear waste. Carbon dioxide pollution causes ocean acidification and this is of tremendous concern to scientists.
What can be done about overexploitation of the oceans?

What is an example of overexploitation?
Often overexploitation occurs when natural populations are harvested for food. A classic example was the persecution of the passenger pigeon, which once was the most abundant bird in North America. One flock was estimated to contain two billion birds.
Why is fishing bad?
Fishing can cause several negative physiological and psychological effects for fish populations including: increased stress levels and bodily injuries resulting from lodged fish hooks. It may also cause the increase of prey species when the target fishes are predator species, such as salmon and tuna.

Is it too late to save our oceans?
It’s not too late to save the oceans: Scientists claim marine life at risk of being wiped out by climate change can recover by 2050 with less fishing, habitat restoration and pollution cuts.
Why is overexploitation bad?
Overexploitation means harvesting species from the wild at rates faster than natural populations can recover. Overfishing and overhunting are both types of overexploitation. Overhunting still poses a big threat to animals in developing regions, particularly primates in Africa.
