Will there be fish in 2050?
An estimated 70 percent of fish populations are fully used, overused, or in crisis as a result of overfishing and warmer waters. If the world continues at its current rate of fishing, there will be no fish left by 2050, according to a study cited in a short video produced by IRIN for the special report.

Why are fish so important?

Will fish go extinct by 2048?
According to study seafood could be extinct in the next 30 years. A study from an international team of ecologists and economists have predicted that by 2048 we could see completely fishless oceans. The cause: disappearance of species due to overfishing, pollution, habitat loss and climate change.
Will humans go extinct?
Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott’s formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.

How many fish are left?
The best estimates by scientists place the number of fish in the ocean at 3,500,000,000,000. Counting the number of fish is a daunting and near-impossible task. The number is also constantly changing due to factors such as predation, fishing, reproduction, and environmental state.
Are we killing the oceans?
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. Factories and industrial plants discharge sewage and other runoff into the oceans.
