Answer:
FALSE
Explanation:
The freshwater refers to all the naturally occurring water on the earth's surface such as rivers, streams, lakes, and glaciers. It does not include the sea and ocean water bodies.
This freshwater plays an important role in supporting the various life forms on earth as well as the ecosystem. Only about 3% of the total water present on the earth is freshwater.
This freshwater is affected by human activities very significantly. The rivers, streams, and lakes are constantly being polluted due to the following reasons such as the toxic chemicals released from the factories and industries mixes with the river, addition of fecal waste and solid waste materials to the water, thereby making the water unsuitable for drinking and other purposes.
Thus, the freshwater present in the world is constantly being degraded and decreasing.
Hence, the above-given statement is False.
