Mankind's Report Card

 20 ways the world has changed since 1st Earth Summit - Politics - CBC News


Sustainability in all Things We Undertake.

The United Nations says humans are more concerned about damage done to the environment than we were 20 years ago — but we're still destroying it faster than we can fix it.

That's part of a snapshot prepared by the United Nations Environment Program in a report called Keeping Track that looks at a wide range of changes that have occurred since the first Earth Summit in Rio in 1992.

The report is designed to be used by legislators at the 2012 Earth Summit in Rio next May.

And far from being a thick report that will just gather dust, Keeping Track is actually a bit of a page-turner, filled with surprising and often encouraging news about our stewardship of the Earth.

The report uses a minimum of text and relies on colourful graphics, charts and satellite pictures to show the major environmental and social changes that have occurred on Earth since the early 1990s, from growing cities in China to the rapidly spreading footprint of Alberta's oil sands.


Changes in the world over the last 20 years.
