Did you know that humans presently rely upon just 20 varieties of plants for 90 percent of their food? Experts throughout the world think that this lack of biodiversity could lead to an agricultural calamity. The Irish potato famine, which led to the death or displacement of two and a half million people in the 1840s, is an example of what can happen when farmers rely on only a few plant species as the cornerstone of their crops.

In just the last 15 years, more than half of the varieties once available have disappeared from seed catalogs. But you can help to reverse this alarming trend. Learn more about seeds, and find out the simple steps to saving your own garden seeds, to help protect the health and biodiversity of the plants we grow.
