Travel through the Rocky Mountains, the Arctic, the Gulf of Mexico, and the Great Lakes and see how these regions have influenced how people have settled and changed the land. Look at strategies people are using to protect these fragile environments. National Geographic Learning�s mission is to bring the world to the classroom and the classroom to life. With our English language programs, students learn about their world by experiencing it. Through our partnerships with National Geographic and TED, they develop the language and skills they need to be successful global citizens and leaders.
