Should I offset my carbon?

Why not just plant a few trees yourself, and take some plegdes to reduce your carbon output? Like washing clothes in only cold water, hang drying them when you are able instead of the clothes dryer, using energy efficient bulbs, and remembering to turn off all your lights... upping your temprature in your home by 2 degrees in the summer and lowering it by 2 degrees in the winter? Erasing your carbon footprint is great, but if you don't make changes to reduce your output now, its not really changing anything. Good for you for taking a stand!
