Keystone Species  3"The Dictionary of Sustainable Management." Presidio School of Management. Retrieved 4/18/08
A species so critical to an ecosystem that its removal could potentially destroy the entire system. A good example of this are Blue Jays, which plant acorns that give rise to oak forests. Without Blue Jays, oak forests are not naturally replenished and without the forests, all other species in the ecosystem cannot survive. It is important to consider keystone species when making any decisions that could affect the natural environment. A small impact on keystone species could cause major disruption for the whole ecosystem.

Kyoto Protocol  3"The Dictionary of Sustainable Management." Presidio School of Management. Retrieved 4/18/08
An agreement developed by and for industrial nations in 1997 at the United Nations Framework Convention on Climate Change (UNFCC) in Kyoto, Japan, to reduce their emissions of greenhouse gases by at least 5% below 1990 levels by 2012. The Kyoto Protocol was adopted in 2005 without the US ratifying it. Currently, the EU expects to achieve the goals two years early, in 2010. Over 200 US cities have decided to meet the Kyoto Protocols on their own.
