have resulted in the emission of carbon dioxide and other greenhouse gases in
the atmosphere. This has increased the global temperature. This increase of
global temperature increase ocean temperatures causing coral bleaching.
Another example is depletion of water sources

vegetation growth due to scarcity of water in the soil (due to lowering of the
water table) for plant growth.
