Students for clean air – While students for clean air hold rallies to push for cleaner air, they are contributing to the carbon issue with every breath they take. But, they make a good point. We must all be concerned for clean air for our kids. When they hold a rally outside the capital building, they can purchase a carbon credit to offset the footprint the group of 500 make. Any rally of any kind should consider purchasing carbon credits to reduce the footprint they make getting to and from the rally, and the air they breathe out at the rally. Purchase your carbon credits today.
