write a paragraph on water scarcity?

Simply put, water scarcity is either the lack of enough water (quantity) or lack of access to safe water (quality).

It's hard for most of us to imagine that clean, safe water is not something that can be taken for granted. But, in the developing world, finding a reliable source of safe water is often time consuming and expensive. This is known aseconomic scarcity. Water can be found...it simply requires more resources to do it.

In other areas, the lack of water is a more profound problem. There simply isn't enough. That is known asphysical scarcity.

The problem of water scarity is a growing one. As more people put ever increasing demands on limited supplies, the cost and effort to build or even maintain access to water will increase. And water's importance to political and social stability will only grow with the crisis.
