Bill McKibben's Project 350 introduces us to the most important number in the world today.

350 is the red line for human beings, as science now tells us that unless we can reduce the amount of carbon dioxide in the atmosphere to 350 parts per million (ppm), we will cause huge and irreversible damage to the earth. We are currently at 385 ppm and still rising.

To help spread the meme, Ian and I both spent some time making videos this weekend.
