Carbon Neutral - Be Greener
I am quite surprised on how ignorant many people (like I was) are about understanding how the day-to-day activities contribute to Global Warming and the issues we face on this planet. As much as we wishes, unfortunately there is no backup or Undo feature 
. To understand how our daily lives contribute towards global warming check out the Carbon Calculator and then read up on how you can offset those emissions and be Carbon Neutral.
However, personally I am not a believer of offsetting, while it is a step in the right direction it is not the solution.
