I just off-set 350 lbs. of carbon just by filling out a short form. It’s all part of Brighter Planet’s 350 Challenge, which is a very minor (but important) way to show support for the fight against climate change. Brighter Planet creates web-based tools that help businesses and individuals “integrate carbon emissions modeling and tap the power of social media,” according to its website. The 350 Challenge helps draw attention to off-setting carbon emissions and demonstrates how small changes by individuals can add up to big results. Signing up for the challenge, Brighter Planet notes, is like turning off 100 light bulbs for a day. Now that’s a bright idea. (Sorry, I couldn’t resist.)
