The ocean: Time to turn the tide
The whale shark, the world’s largest fish, is an endangered species.
Less than twenty per cent of the world’s ocean has been explored so far. That is not a lot. But it is enough for us to know that the ocean is threatened by global warming, acidification, and pollution. Coral bleaching is just one illustration of the decline of marine ecosystems. The consequences of these changes are not just environmental. Nearly three billion people depend directly on marine and coastal biodiversity for their survival. By 2050, coastal areas that are home to 300 million people could be threatened by rising sea levels due to climate change.
