passage 1
P1
Because most agricultural practices in North America produce row after row of only a few, genetically identical, varieties of crops, the continent's food system rests precariously on a rapidly eroding genetic base, increasingly susceptible to pests and disease. ███
Problem ·
Crop system precarious
Because crops are genetically homogeneous
Potential Solution ·
Conserve genetic info of heirloom varieties
Challenges ·
Farming methods unsuited to conservation
