4.	Increased population level	A.Stress on the environment

Chipko movement was a forest conservation movement in India. The movement originated in 1973 at the Himalayan region of Uttarakhand.

With the help of "Photovoltaic cells", the solar energy was converted into electricity.

Mini-hydel plants used the energy of streams to move small turbines, which helped in the generation of electricity.

Rise in the population level resulted in increased environmental stress.
