NBSE Class 10 Environmental Education Chapter 1: Protection of landscape and conservation of water
A good landscape gives pleasure to the eyes. It also ensures pure air to breathe and pure water to drink. Of course, it is the duty of municipal authorities to provide a clean landscape in the area you are residing in. But, we have also a role to play. We assist the authorities in maintaining a clean landscape. This can be in the form of not littering the streets, not spoiling the beauty of picnic spots and not leaving the rubbish on the hills and mountains.
