So I’m writing an essay about drivers of coral reef bleaching, and reading about acidification and its effects on marine mammals that secrete calcium carbonate, and this new research pops up. Interesting immediate adaptation to cope with lower pH levels in marine environments; although I’m not sure how long-term (and effective) an adaptation it might be. Similarly, some coral species and their symbionts are more tolerant of some drivers of bleaching than others. Again, in the short-term that helps those species, but it’s not clear how far beyond their normal thresholds for CO2, irradiance, thermal stress and acidification they can survive. And then there’s coral diseases… We are pushing the limits, changing environments and testing tolerance thresholds for so much of the world’s wildlife, and not in a good way.
“In a new report, published by the University of Queensland, researchers say the rat is officially history — the first documented mammal extinction due to climate change.”
Very sad news.
Sea Shepherd are making a film! Fantastic. This combines my two favourite things – and my two degree subjects – in one amazing project, hence my delight at reading this news. This is why I’m studying what I study. Art and science combined to educate and motivate us all to make the vital changes we need to make to halt this destructive path that our species is on.

China, a country responsible for mind-boggling and heart breaking levels of environmental destruction and decimation of the world’s animal and plant species.
Continuing on a theme regarding over-fishing, this article discusses the massive fishing subsidies we hand over every year which fuel the violent emptying of our seas and destruction of marine ecosystems.
With just 4% of the world’s oceans classified as protected, it seems there is a lot of conservation work to do. Not just conservation work out in the field, but amongst governments and in changing laws and creating acts and bills to protect precious marine habitats.
Oxybenzone, an ingredient in sunscreen, has been shown to damage coral DNA, damage juvenile coral and cause bleaching, which can kill off swathes of coral reef.
However, let’s not forget the far bigger cause of coral reef die off – climate change and rising sea levels.
