Water is the most important substance on Earth; it is also the most threatened - by climate change, trash, and pollution (such as the recent oil spill in the Gulf of Mexico). Young people across the globe are responding to the world water crisis by transforming their ideas and energy into action and participating in service learning. The call to service is being sounded by world leaders such as President Barack Obama, Jane Goodall, and Philippe Cousteau - grandson of Jacques Cousteau and a champion of the new generation of environmental activists. Teens are answering the call to help our environment by being green, and to rescue our oceans and waterways by going blue. "Going Blue" vividly presents facts and statistics about Earth's oceans and waterways and information about the issues surrounding our current water crisis. Readers will find a wealth of strategies and examples that help them see themselves as change agents and move forward to complete an effective service project.
