Use only what you need.
Buy only what you need.
recycle old newspapers/magazines
--use them as gift wrappers.
recycle bond papers
--use the back side for printing your handouts and papers
(if it's okay for your teachers).
Conserve energy, water, tissue papers.

remember, you encourage production by buying stuff you don't really need
-- especially those made of plastic.
and by doing so, you contribute to the pollution in our country.

(No more NBS for me..less NBS for me.)

This is a start.
And the reward is not a good grade, not recognition.
