How dead is the Great Barrier Reef?

submitted by Mordhaus

7 years 6 months 1 week ago

Australia's Great Barrier Reef is the largest coral reef system in the world and the only living structure visible from space. Although ecosystem managers in Australia have worked hard to preserve the reefs, the past couple of decades have brought a new threat that can't be solved by any one country alone: human-induced global warming. Rising ocean temperatures have caused mass coral bleaching in coral reefs around the world, in every tropical ocean from the Caribbean to the South Pacific. This is now considered to be the biggest threat that coral reefs face, and they face many, including overfishing, pollution, storm damage, and invasive species.

So...by 2050 corals will bleach yearly, but they cannot recover with a bleaching event happening once every 10 years (a level we've already long ago passed in many areas). This means those bleached now have almost zero chance of survival/recovery.

As a main base food source for the oceans from gametes to polyps, as well as a habitat for over 25% of species (and probably a higher percentage of bio mass), the loss of reefs will be the death of the already struggling oceanic food web.

Skip the beef, and save the reef :-)
Choose the bean pattie instead.
