Can be used as an introduction to the discussion about the huge significance of genetic diversity for life on our planet. A comparison can be made with the species diversity of other crops, such as corn or soy. How can historical famines, such as the Irish potato famine in the 19th century, be explained in terms of the genetic poverty of crops?
