The fact that two massive companies like Google and Wal-Mart actually acknowledge that there is a problem and are attempting to find new items that decrease our footprints on the earth just shows how serious Global Warming really is. When these companies take on projects such as they did, they spread awareness, education and ideas. We have to hope that others will follow suit. For our world truly is dying and humans are the only ones who can stop it from completely becoming destroyed.
Remember its not just the companies and governments responsibility, ITS EVERYONES.
