What will be an ideal response?
Intensive farming and ranching lead to the production of a few highly
profitable varieties that can be grown on a large scale for less money
compared to what it would cost to grow a diverse crop population. One of
the problems with this practice is a huge crop loss is a possibility if a pest
or blight strikes one or several of these crops, such as in the Irish potato
famine.
