The Millennium Ecosystem Assessment
Pilot Analysis of Global Ecosystems | EarthTrends

A resource for teachers, students, researchers, and journalists — from those who are simply curious to those who require hard data — EarthTrends is a new and unique online environmental information database developed by the World Resources Institute.

EarthTrends gives you access, free of charge, to current information about ecosystems, people, economies, places, and social issues at national, regional, and global levels. But EarthTrends isn't just a mountain of data. EarthTrends also offers a variety of features to spark or satisfy your curiosity: stories, maps, graphics, and country profiles — as well as searchable databases and data tables.

Looking for statistics?

Did you know that the average US citizen consumes about twice as much grain, twice as much fish, three times as much meat, nine times as much paper, and eleven times as much gasoline as someone living in a developing nation? Compare people's resource use worldwide via the data and graphics in EarthTrends.

Taking a trip?

Find out everything about the ecology and economy of the country you're visiting — whether it's the number of bird species in Costa Rica or the percentage of Indonesia's population that lives in poverty.

Confused about energy?

Has all the talk about the "energy crisis" in the United States got you wondering where our power comes from and whether renewable energy supplies are increasing? Short, well-illustrated analyses presented as feature stories in EarthTrends make complicated topics and trends understandable.

Want a graphic presentation to help you visualize the data?

You've heard how most of the US grasslands have been converted to farms and urban areas, and what's left is being fragmented with roads — but you can't visualize what that looks like?

EarthTrends offers more than 60 full-color maps to help you picture everything from grassland condition in the United States, to soil degradation in Asia, to per capita water availability worldwide. Best of all, EarthTrends explains why you should care.

It's easy to become overwhelmed by news about pressures on the world's resources, especially on a global scale, and stymied by what the solutions might be. EarthTrends puts global environmental trends in terms we can all grasp. Check out EarthTrends at
