A six minute video posted on Vox shows how important a good diet is. This will be useful in my stats class, but it's also relevant for Resources: note that while Borlaug's work didn't have a direct effect on infant mortality rates, the changes he contributed to made a big difference for a lot of people. While genetics are important, diet can also determine as much as 20% of a person's height, which is why South Korea saw such impressive gains in height in the late 20th century. I always appreciate a little good news!
