Question

What are the problems of water availability in the world

Answer 1

Answer:

Half a billion people in the world face severe water scarcity all year round. Half of the world's largest cities experience water scarcity. A mere 0.014% of all water on Earth is both fresh and easily accessible. Of the remaining water, 97% is saline and a little less than 3% is difficult to access.

Answer 2

Answer:

Climate change, such as altered weather-patterns (including droughts or floods), deforestation, increased pollution, green house gases, and wasteful use of water can cause insufficient supply.
