What are two main problems with overfishing?

Another example of overfishing is the Atlantic Cod stock between the 1970s and the 1990s. As technology increased in these years, cod stocks became more accessible to fishermen. Although these populations were once believed to be unlimited, the fish population soon plummeted to unsustainable levels.

What is the main problem with fishing?

Problems such as overfishing, plastic pollution (as explored in the documentary Seaspiracy), habitat degradation and bycatch (capturing unwanted marine life when fishing for a certain species) are imposing drastic consequences that have a ripple effect across the entire planet.

Where is overfishing most common?

The Mediterranean is the world’s most overfished sea, with the highest percentage of unsustainably harvested fish populations, according to a recent report from the United Nations Food and Agriculture Organization.

How can overfishing be prevented?

By monitoring catch levels annually, NOAA Fisheries and the councils can prevent chronic overfishing and the depletion of fish populations.

Global warming is causing sea levels to rise, threatening coastal population centers. Many pesticides and nutrients used in agriculture end up in the coastal waters, resulting in oxygen depletion that kills marine plants and shellfish.
