Our unsustainable habits are propelling climate change, and as a result, the Great Barrier Reef is under immense environmental stress. Coral bleaching has reached record levels and no one knows if or when the coral will ever recover. This is concerning not just from an environmental perspective, but, as a new report by Deloitte Access Economics shows, that loss of the reef would represent an “economic catastrophe” as it is estimated to be worth $56 billion (AUS), or $42 billion (USD). As water temperatures rise, the coral expels algae living within, causing it to turn ghostly white (a phenomenon known as coral bleaching).
