Sustainability Basics

Definitions – Three “Rs”
Reduce, Reuse and Recycle - the basis for sustainability ►Reduce - reduction in the use of resources by providing energy efficient systems and water conservation measures ►Reuse - the reuse of resources such as renovating an old building as opposed to tearing them down to build another decreases resource demand ►Recycling – use of recycledmaterials decreases new resource demand and keeps resources out of landfills

Definitions of Sustainability
The capacity to equitably meet the vital human needs of the present without compromising the ability of future generations to meet their own needs by preserving and protecting the ecosystems and natural resources.

Definitions of Sustainability
National Academy of Sciencesees 1979 as the year of the earth’s “tipping point” – that is, the year when the consumption of natural resources exceeded the earth’s ability to replenish them. While there is a multiplicity of collective and individual solutions, a culture of sustainability offers significant hope that humanity can take action to address its overuse of resources
