Savers

Getting past the screen savers and Life Savers, I found the Seed Savers Exchange. This is one initiative of seven focused on environmental issues that affect life on this Earth. The fund considers "deteriorating quantities of genetic seed stock, a greatly depleted farmable soil base, insufficient regional food stocks for world populations, a greatly lessened per capita water supply, and a greatly lessened forestry base."
The Seed Savers Exchange specifically works to promote diversity in seeds and plants. They have more than 20,000 cultivars (varieties of plants that have been cultivated). They have also saved thousands of endangered species around the world.
