The fourth Global Environment Outlook launched on 25 October provides a comprehensive and authoritative overview of the state of the environment.

45,000 square miles of forest are lost across the world each year
60% of the world’s major rivers have been dammed or diverted
34%: the amount by which the world’s population has grown in the last 20 years
75 thousand people a year are killed by natural disasters
50%: The percentage by which populations of fresh fish have declined in 20 years
