How much of the ocean is dying?
Some 252 million years ago, an unparalleled mass extinction event transformed Earth into a desolate wasteland.

Is sea life in danger?
There are not just one or two marine animals in danger of extinction. Instead, a huge percentage of marine life is dying off at alarming and unsustainable rates. Many sea creatures die a painful death after getting caught in plastic bags, containers and fishing nets, as well as ingesting plastic, metal and even glass.
What happens if ocean life dies?

Will there be fish in 2050?
The world will be able to catch an additional 10 million metric tons of fish in 2050 if management stays as effective as it is today, says the report. … If such a management system is enforced, an additional 35 million metric tons of fish could be caught sustainably in 2050.

Is there hope for the ocean?
Yet even in the grim view of environmental protection, there is hope. Scientists say that restoring the oceans by 2050 is a grand challenge, but with a global redoubling of conservation efforts, it can be achieved.
Will the oceans ever dry up?
The natural increase in solar luminosity — a very slow process unrelated to current climate warming — will cause the Earth’s temperatures to rise over the next few hundred million years. This will result in the complete evaporation of the oceans.

Why are the fish dying?
Of known causes, fish kills are most frequently caused by pollution from agricultural runoff or biotoxins. Ecological hypoxia (oxygen depletion) is one of the most common natural causes of fish kills. The hypoxic event may be brought on by factors such as algae blooms, droughts, high temperatures and thermal pollution.
What is the deadliest ocean?
REUTERS/Bobby Yip The South China Sea and East Indies, eastern Mediterranean, Black Sea, North Sea, and British Isles are the most dangerous seas in the world, with the greatest number of shipping accidents in the last 15 years, according to a report released by the World Wildlife Fund (WWF).

What do humans do to affect the ocean?
Human activities affect marine ecosystems as a result of pollution, overfishing, the introduction of invasive species,and acidification, which all impact on the marine food web and may lead to largely unknown consequences for the biodiversity and survival of marine life forms.
