How can people protect their environments?

There are various ways people can protect their environments. There are several parts of environment, including water, air, land, etc., that can be protected by modifying our day to day habits. We can protect the air by using less fossil fuels. This can be achieved by using more efficient vehicles or electric vehicles. Carpooling or cycling or walking are some other options. Use of more efficient electrical devices can also help us save electricity, most of which is produced by use of fossil fuels. We can save our water bodies by ensuring that no one disposes off their waste directly into the surface water bodies, such as rivers, streams, lakes, etc. We can protect our land by safe disposal of our solid wastes. We can help the environment by recycling and reusing as much of our waste as possible.

Hope this helps.
