Hi !

Why is water conservation necessary?

B. Water shortages are expected in 40 states before the year 2026.

The correct answer is B) Water shortages are expected in 40 states before the year 2026.

Water conservation is necessary because "water shortages are expected in 40 states before the year 2026."

It is well known than 80% of the planet is water. So what is the problem? The problem is that freshwater for people consumption only represents 3 to 5% of that amount of water on planet earth. So that is why is extremely important to conserve this vital liquid. There are places in developing countries where people have to walk many miles to get to the well and get some water, daily!

In the United States, some states have been facing water problems. That is the case of California, where the government has limited the use of water to the necessary human consumption.
