What are three things you are going to try or change about yourself so that you can have a larger impact on helping the envronment?

The first thing I would like to do is us paper bags instead of packets. This will keep me from burning the packet and make me recycle the paper bags which would cause lesser pollution. This method will also keep the environment clean. The next I will try to do is switch off all the lights that are not needed.
Even if I am going out of the room for a short while I will switch off the tubelights and bulbs. If light is really needed I shall use CFL lights. The last thing I will do is to carpool when ever possible. If someone is going to the same place as me I will go with them.
