1. If you leave your office, turn off the lights, air conditioner and computer. This goes for lunch time as well.
2. Bring a water bottle to work instead of using plastic cups to drink from and to avoid buying bottled water.
3. Stop using paper/plastic for grocery. Get yourself a bag and make that a cloth bag/reusable bag. It's the rage now.
4. If it can't fit you anymore, find someone that can. :D
