China alone is home to 1. Overpopulated areas face many challenges, most of which stem from the impact of climate change or human overexploitation of natural resources, but a recent study published by Nature Communications points to rising sea levels as one of the greatest dangers.
According to this study, coastal areas currently inhabited by million people are set to experience annual flooding by , unless measures are taken to hold back the water — a figure three times higher than previous estimates. Asia is the area at greatest risk of flooding due to climate change , due to its very low-lying land and overpopulation.
