Children who played outside every day, regrdless of weather, had better motor coordination and more ability to concentrate.

When you're sitting in front of a screen, you're not using all of your senses at the same time. Nowhere than in nature do kids use their senses in such a stimulated way.

A natural environment is far more complex than any playing field.

Increasingly the evidence suggests that people benefit so much from contact with nature that land conservation can now be viewed as a public health strategy.

A lot of people think they need to give up nature to become adults but that's not true. However, you have to be careful how you describe and define 'nature.

When we raise our children, we relive our childhood. Forgotten memories, painful and pleasurable, rise to the surface.... So each of us thinks, almost daily, of how our own childhood compares with our children's, and of what our children's future will hold.

Each of us-adult or child-must earn nature's gift by knowing nature directly, however difficult it may be to glean that knowledge in an urban environment.
