Big blue marble, blue planet, Gaia, terra firma, terrestrial sphere, world- these are some of the words we use to describe Earth.
On April 22 we will be celebrating the 40th anniversary of Earth Day, which was first initiated on April 22, 1970 by Wisconsin Senator Gaylord Nelson.
Back in 1990, in celebration of 20 years of Earth Day, the Library’s science reference staff compiled an Earth Decade Reading List . This guide and similar material, was distributed at the 20th anniversary celebration on the National Mall (see picture). Our reference staff also planted a tree that day!
The Earth Decade Reading List contains titles by and about precursors and founders of the environmental movement, as well as classic publications on environmental issues.
20 years later, science reference staff is still creating publications related to environmental issues such as Alternative Fuel Vehicles and Combustion Processes , Green Roofs , Solar Ovens and Cooking and Sustainable Agriculture . For teachers and students we have a guide for Environmental Science Fair Projects.
To make it easier for the reader, we have organized and selected some of the Library’s environmentally themed guides, events, and the like into an Earth Day Guide .
