Half of ocean life died out in past 45 years

Overfishing and other similar threats have caused the number of fish and animals in the ocean to have halved since 1970 with conservation group WWF calling the situation ‘critical’.

Not only fish are dying out: The World Wide Fund for Nature (WWF) study tracked the populations of some 1,234 species, such as seals, turtles, dolphins and sharks.

Unfortunately all the threats are man-made. The study claims that the global fishing fleet is too big, and between $14bn and $35bn go into supporting it every year.

Other dangers include coral reefs and mangroves damaging, coastal development, pollution and climate change. The latter has a more direct impact on the ocean’s ecosystem than one might imagine, as rising temperatures increase acidity in waters.
