For years, British environmental activist Mark Lynas destroyed genetically modified food (GMO) crops in what he calls a successful campaign to force the business of agriculture to be more holistic and ecological in its practices.

Earlier this month he went in front of the world to reverse his position on GMOs.

"Contact with nature is not some magical elixir but the natural world is the substrate on which we must build our existence," writes Stephen Kellert in his new book Birthright: People and Nature in the Modern World.

In it, he tells stories of the environment's effect on us, and ours on it. His writing builds on the traditions of Thoreau, John Muir and Rachel Carson. Modern society, he argues, has become adversarial in its relationship to nature, having greatly undervalued the natural world beyond its narrow utility.

Astronomers have discovered a clump of 73 quasars that spans four billion light years at its widest point--that's like 40,000 Milky Way galaxies lined end-to-end. The only problem? Theory says the quasar cluster is too big to exist. Astronomer Gerard Williger and reporter Ron Cowen discuss this cosmological oddity, and other news about the cosmos.
