Although 70.8% of the earth inhabited by humans is covered by the ocean, the global water storage is about 1.37 billion cubic kilometers, and freshwater accounts for only 2.53%. In all of this freshwater, 68.7% are stored in glaciers in the Antarctic and Arctic and In the permanent "snow cover", it still takes time for humans to use these freshwater resources. Due to excessive blind exploitation of water resources, wanton waste and pollution, humans can use less freshwater resources that are already scarce. What is incorrect about the above paragraph? ['Since freshwater resources have not been fully developed, the potential for humans to use freshwater resources is huge.', 'The freshwater resources available on the earth are mainly concentrated in the Antarctic and Arctic.', 'Without effective measures, humanity will face a crisis of lack of freshwater resources.', 'Blind mining, wanton waste and pollution, make human freshwater less.']
