That's the easiest thing to do. Even I can do that. This is my list.

- Cook your food at home instead of buying from takeaways. Its good for your health too.
- Cover the bowls with a saucer instead of palstic wrap when putting it in the fridge. Or use reusable conatiners with lids.
- Carry your own water, so that you don't have to buy a bottle. If you do buy a bottle, don't throw it, reuse it by filling it with tap water.
- Buy second hand stuff whereever posiible.

Does anyone has any other ideas?
