The ocean covers more than 70 per cent of our planet’s surface. Thanks to its ability to absorb the excess carbon and heat generated by climate change, its potential to generate clean energy and the bountiful source of food it provides to both humans and animals, there’s little doubt the ocean is vital for the continued survival of the human race and of the planet itself. But all is not well. Ocean temperatures are climbing, coasta...
