Some of the threats posed by climate change can appear rather esoteric or abstract. One of these is ocean acidification – it is not immediately obvious why we should care. A recent paper by Sara Cooley and colleagues give a good example of why the threat of changing ocean chemistry matters.
It might surprise you to learn that fish are more similar to fruit and vegetables than they are to poultry, cattle, or any of the other animals we eat. At least, they are if you think about the variety of shapes and sizes that fish and fruits and vegetables come in.
