Here is a description of Gaylord Nelson's 5 characteristics. But 1st I want to let you know who Gaylord Nelson is. He was a Senator from Wisconsin, who founded Earth Day, and was a huge advocate for environmentalism in the in the 1970's and 80's and he preached sustainability. A sustainable lifestyle, is one that doesn't hurt its surronding community and environment while using resources. Gaylord Nelson passed away in 2005, but his influence still lives, here are his 5 characteristics of Sustainability. (*)

1. Renewability- Community must use renewable sources such as water, topsoil, and energy sources no faster than they can replace themselves. It cannot exceed the rate of generation.
2. Substitution- A community should use renewable instead of nonrenewable resources. To be sustainable, a community has to make the transition before the nonrenewable resources become little.
3. Interdependence- A sustainable community recognizes that it's a larger system and that it cannot be sustainable unless the larger system is also sustainable. Does now import goods so that it's richer than other communities nor does it pollute other communities.
4. Adaptability- A sustainable community can absorb shocks and adapt to take advantage of new opportunities. It requires a diversified economy, educated citizens, and a spirit of solidarity.
5. Institutional Commitment- A sustainable community adopts laws and political processes that mandate sustainability. It supports sustainable production and consumption. Teaches people how to value and practice sustainable behavior.
