This week marks the 35th anniversary of "Earth Day." On this program, Marcia Franklin and guests look at what humans can learn from animals and plants about living more sustainably on the land.
Author Janine Benyus describes how scientists and product developers are trying to manufacture products that mimic the strategies of certain animals and plants, so that fewer toxic chemicals can be used. For example, scientists are developing paint that will mimic the self-cleaning properties of leaves. Developers are also trying to learn how spiders spin silk stronger than Kevlar, using just water.
Larry Selzer talks about the actions to preserve land conducted by the Conservation Fund, a private, non-profit, non-advocacy organization. The Fund, started in 1985, helps purchase and set aside tracts of land, including portions of the Lewis and Clark Trail.
