“Physical activity is undeniably ‘green.’  The environmental benefits that result from changes like biking instead of driving to work are significant, and the health gains from incorporating exercise into a daily lifestyle are an added bonus to personal health and wellness.”

– ACSM President Mindy Millard-Stafford, Ph.D., FACSM [ here ].

Well, there ya go.  Get exercise, save the planet, be healthier and happier.  If you don’t care about the earth then get exercise for your own sake.
