When we make concrete roads during rainy season the water don't go underground and it gets discharged and our fresh water that we can use is only about 1% on the planet a big source of which is underground water. For daily purpose we use that water for our daily activity & drinking purposes. And rain is the cyclic natural process to recharge the water of underground. But when we make concrete roads everywhere, big part of rain water goes else where and underground water don't get charged up.

And there is a drastic decline in the graph of underground water level. And the water we take out from underground is mostly drained out from our system and it goes in the river, lake and oceans etc.. that increases the level of rivers and lakes at a continuous fraction of rising water level resulting in flood and other such disaster. We all read law of conservative of mass in general living conditions. So how can we expect that the underground water level will remain and still we don't allow it to get recharged during rain. By taking steps today we can save ourselves from all troubles. We need to make changes fundamentally to recharge underground water through concrete roads. I will propose my ideas soon.
