Some of the reasons due to which animals are getting endangered are climate change, poaching and habitat loss. The Elephant population was halved in between 1981 and 1989 due to poaching and 80% of the Orangutans have disappeared in the last 100 years due to habitat loss.
The total amount of water on earth is 1424192640 cubic Km. Out of this 97.5% is salt water and 2.5% is fresh water. Out of the fresh water, 70% is frozen while 30% is found underground. By 2025, about 4 billion people will be facing water scarcity or flooding.
