Answer: The given statement is false.
Step-by-step explanation:
In industries water is used for many purposes like washing, cooling, fabricating, diluting etc.
Therefore, huge amount of water is used by industries and also waste water or non-consumptive water is thrown by industries into rivers, sea, lakes etc.
An industry can avoid the unnecessary usage of water in various process so that water can be conserved as water is a precious resource of nature.
Therefore, the statement since 40 percent of industrial water use is non-consumptive, there is little that industry can do to conserve even more water, is false.
