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.
“There is a massive, massive decrease in species which are critical,” said Marco Lambertini, director general of WWF International.
When it comes to dinner staples such as tuna or mackerel, populations have fallen by a shocking 75 percent since the seventies, according to a study by the WWF and the Zoological Society of London (ZSL).
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.
