Global warming affects every living thing on Earth--people, plants, and animals. While scientists are working to better understand how the Earth's climate will change over time, some effects are already evident: rising sea levels, shrinking glaciers and polar ice caps, changes in the distribution of plants and animals, increases in intense weather, and thawing of permafrost. As global warming is caused by an overabundance of greenhouses gases in the atmosphere, scientists suggest that it can be slowed by reducing greenhouse gas emissions and recapturing carbon dioxide (CO[subscript 2]) from the atmosphere. For average citizens, this means reducing the amount of energy they use in their daily lives. Kids--and teachers--can be instrumental in making a difference and changing the planet's future. This article presents some activities and resources that can help protect the planet. (Contains 9 online resources.)
