Plants for Food and Fiber

Unit Overview:

Humans have always depended on plants as a source of food and fibre, and to meet a variety of other needs. To better meet these needs, technologies have been developed for selecting and breeding productive plant varieties and for maximizing their growth by modifying growing environments.  Long-term sustainability requires an awareness of the practices humans use and an examination of the impacts of these practices on the larger environment.


  1. How do we produce useful plants?
  2. What techniques do we use, what knowledge are these techniques based on, and how do we apply these techniques in a sustainable way?
