A dynamic aerial exploration of our changing planet， published on the 50th anniversary of Earth Day
 
The Human Planet is a sweeping visual chronicle of the Earth today from a photographer who has circled the globe to report on such urgent issues as climate change， sustainable agriculture， and the ever-expanding human footprint。 George Steinmetz is at home on every continent， documenting both untrammeled nature and the human project that relentlessly redesigns the planet in its quest to build shelter， grow food， generate energy， and create beauty through art and architecture。 In his images， accompanied by authoritative text by renowned science writer Andrew Revkin， we are encountering the dramatic and perplexing new face of our ancient home。
