As nature falters, it will drag down economic growth across the globe. Climate change alone is expected to cut 4 per cent off global gross domestic product annually by 2050. As temperatures rise and the crisis deepens, that number will rise to a staggering 20 per cent by 2100, the report says. That would be just a little less than the contraction the United States of America suffered during the Great Depression of the 1920s and 1930s. 

Those losses will be magnified by the effects of pollution and the disappearance of nature. The poor will suffer the most from this economic upheaval, and the gap between them and the rich will continue to widen.
