Climate change is a threat unlike any other that civilized man has ever faced. Most scientists agree that by curbing our carbon emissions through reduced reliance on fossil fuels and by promoting new forest growth, we can help stave off the worst of the dangers. So what can you as a Dartmouth student do? Offset your personal carbon emissions by donating to nonprofits like www.CarbonFund.org. These groups take your donations and channel them into renewable energy development, the protection of woodlands, and energy efficiency initiatives. Short on cash? Let your parents know that for only pennies more a day on their electric bill they can choose to purchase clean energy from their local suppliers.  They can use sites like www.RenewUs.org to get information specific to their region about purchasing renewable energy generated from sources like wind, solar, and small-scale hydro.
