Water from various sources were directly taken and used for all sort of home and agricultural work.
The never wanted to see today's unhealthy world which is getting difficult to live in.Thats the sad truth they say.Now the world is turning hell.Air pollution and water pollution is a daily issue.Now for example Delhi govt. has made stern rules regarding the use of vehicles to minimise the air pollution.
NOw to protect the environment so dear to us

Air pollution needs to be checked and water pollution should be reduced as it is the basis of life.

Factories should be inspected and warned to check the released chemicals and treat them before releasing them into water and air.
