Four changes that can be incorporated in my life style as a move towards sustainable use of available resources are:

1. I shall reduce wastage of electricity by switching off unnecessary lights and fans. I will use solar lamps instead of electric bulbs and will use CFL instead of traditional bulbs.

2. I shall reduce the use of petrol by pooling my car or by using public transport where it is necessary.

3. I shall segregate non-biodegradable waste consisting of plastic, glass, and metal from other waste and send it for recycling.

4. Whenever I will go shopping I will carry my own jute bag.

5. I shall pass on my books and notes to my junior instead of disposing of as waste paper
