 I've pledged to pick up our pet waste and put the bag in a trash can because waste left on our ground and on our yard trash piles pollutes our local streams and waterways. I pledged to dispose of unused pharmaceuticals safely at a police station or pharmacy rather than flush them down the toilet because those drugs find their way back into our drinking water. We pledged to walk, bike or ride the bus because less cars on the road means less air and water pollution. You ready? I pledged to recycle batteries and electronics and not throw them in the trash because they can pollute our drinking water. I pledged to recycle clean paper and cardboard as well as containers made from plastic, metal and glass because I want to leave the cleaner earth for future generations by keeping pollution out of our rivers and oceans.

Let's show our friends across the country that in Columbia, South Carolina we stand together in our commitment to clean water.
