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.
NBSE Class 10 Environmental Education Chapter 2: Conservation and management of forests and ocean resources
