        The Botany of Desire | Control: Far Afield - PDF

        Biological diversity helps an ecosystem adapt to changes, including threats, from the environment. Michael Pollan explores risks inherent in one of the most widespread practices in modern agriculture. It's called monoculture, and it refers to cultivation of single or very similar varieties of a food crop on large acreages. This lesson encourages students to investigate the human role in developing a cultivar of their choice. Students will explore the relationship between cultivars and wild varieties, discuss the need for cultivars, and discuss risks from modern agricultural practices.
