We need to protect the world we live in -- for ourselves and future generations. What is going to happen to Planet Earth? This challenging new series draws attention to the most urgent environmental concerns-and suggests positive ways to prevent more damage. Earth Watch explains the issues-from the perils of pollution and global warming to ozone depletion and habitat destruction-and then suggests ways to help. Hands-on experiments show readers how to explore the science behind the facts, while action globes suggest ways to make a difference on a daily basis. To highlight what is already being done, eyewitness reports from professionals-including a glaciologist in Antarctica and a garbologist in New York City-describe how their work is improving the management of the planet.
