Earth, Sustainability, Eco-Friendly

I just opened up an ecard sent to me for my birthday.  In the card a picture with a palm holding a small miniature tree pops up, and it made me think..what if we (you, me and anyone) were to hold the earth in our palm.. how would you take care of it? how would you feel? Are there changes that you would make to your current lifestyle to protect the earth?

I know that I would feel responsible for the survival of the planet.  I would do anything to protect it and keep it from harm.  What would you do?
