Give reason: our surrounding area should be free of stagnant water.

Stagnant water:

1. Water that has been lying for a long time is referred to as stagnant water.
2. Stagnant water becomes an ideal environment for the growth of biofilms, which are collections of bacteria or fungi when there is no movement or aeration.
3. It is to be noted that the longer it sits, the more dangerous the water becomes.
4. Because stagnant water can lead to numerous waterborne illnesses in both humans and other organisms, our surrounding environment should be free of it.
