Great Barrier Reef is severely bleaching

Due largely to the record-breaking high temperatures we’ve had lately, large sections of the northern Great Barrier Reef have begun bleaching (i.e., expelling the symbiotic algae that live within coral tissue and serve as a life-support system for corals). This is very bad news. In past bleaching events like this, some coral reefs never recover and become seaweed-dominated reefs lacking coral. Most experts agree that the root causes of the high temperatures (and the resulting coral bleaching events) include the burning of fossil fuels and release of other greenhouse gases into the atmosphere (e.g., through beef production)…which are both ultimately driven by human overpopulation and overconsumption.

Below are some recent photos taken by coral reef scientists Wen-Sung Chung and Justin Marshall (University of Queensland) from Lizard Island on Australia’s northern Great Barrier Reef. They tell a sad, rapidly-unfolding story of desperate corals.
