Grasses

In terms of the economic and nutritional values of foods provided for humans and domestic livestock, no other plant family is as important as the grasses. All of the important cereals and grains are members of the grass family, and some of these agronomic species have been cultivated for thousands of years. There are useful cereal species available for all of the climatic zones in which humans commonly live, and this has been one of the most important reasons why our species has been able to develop such large and prosperous populations during the past several thousand years.
