From Scientific American: Does Consumerism Make Us Crazy?

The term ecopsychology, first coined by writer and theorist Theodore Roszak in his 1992 book, Voice of the Earth, is loosely defined as the connection between ecology and human psychology. Roszak argues that humans can heal what he calls their “psychological alienation” from nature and build a more sustainable
society if they recognize that we all have an innate emotional bond with the natural world.

Last Child in the Woods: Saving Our Children from Nature Deficit Disorder, by Richard Louv, argues that kids are so plugged into television and video games that they’ve lost their connection to the natural world.
