Join Big C, the Cowboy Carbon Atom, as he shows children the wonderful world he is part of. He will show all the material things that he can turn into. Big C will also explain the cycle of carbon in nature, which allows animals and plants to live on earth, and how important this balance is. Children are the future, and sometimes they take nature for granted, so Big C will show them that without Big C in the world, life would not exist. Big C will also show how carbon is turned into things we eat and turned into material used to run our cars and build our houses.
