An atlas of environmental change compiled by the United Nations reveals some of the dramatic transformations that are occurring to our planet. It compares and contrasts satellite images taken over the past few decades with contemporary ones.
These highlight in vivid detail the striking make-over wrought in some corners of the Earth by deforestation, urbanisation and climate change.
The atlas has been released to mark World Environment Day.
The United Nations Environment Programme (Unep) produced One Planet Many People: Atlas of Our Changing Environment in collaboration with other agencies such as the US Geological Survey and the US space agency (Nasa).
