Bring your learning to life with compelling images, media and text from National Geographic. GREEN will help you develop a clearer understanding of the world around you through engaging content. This reader's themes are inspired by our changing relationship with the earth, based on an understanding that the planet's resources are finite and that our future depends on preserving them. While the term "green" signifies a level of awareness about environmental concerns, it is used here in the broadest sense, to draw your attention to the state of the planet and to promote discourse on how to address the needs of the human population as well as the ecosystems that sustain life in our world. To what extent we see ourselves as members of a global community and to rethink how we will meet the growing needs of our population in the future are the two central questions this collection asks you to consider critically.
