Amaranth offers Mexicans promising corn alternative
Corn is a dietary staple in much of the world that's threatened by climate change. This problem is particularly acute in Mexico, where corn tortillas and tamales are an important part of food culture. A different traditional grain could offer a solution to the difficulties of growing corn in an unstable climate.
This is a great example of how heirloom crops can offer valuable alternatives in a dangerously homogenized food system.
