World Food Prize

The World Food Prize, an award set up by Norman Borlaug to honor others who fought against hunger, was held in Des Moines this week.* The prize went to Gebisa Ejeta, an Ethopian-American plant breeder and geneticist, who developed new breeds of sorghum that increase yields as much as fourfold.

His sorghum breeds deal better with drought, a trait that will become only more important around the world as competition for fresh water increases. Perhaps even more importantly though, they are resistant to striga**, a parasitic weed that attaches to the roots of crops, drawing off nutrients and severely decreasing yield (20-80% less than uninfected fields). Each plant produces tens of thousands of tiny seeds than can lie dormant in the soil for up to twenty years waiting for the best moment to strike, so once a field is infected with striga, it isn’t going away. The common name for striga is witchweed which fits the species perfectly. Striga resistant sorghum is a very good thing.

My appreciation and congratulations go out to Gebisa Ejeta.

*This is the first time the prize has been awarded since Dr. Borlaug passed away.

**On the more basic research side, the study of striga lead to the discovery of a new class of plant signaling molecules strigolactones.

Could someone check my math?

Deliciousness

Deliciousness

Per capita meat consumption in America is 124.8 kilos per year. Which is ~275 pounds per year, 5.3 pounds per week, and almost exactly 3/4 of a pound per day.

That seems like a lot to me. I mean that’s three quarter-pound hamburgers each and every day. On occasion I’ve hit twice that, maybe thrice in a single meal. But when I say on occasion, I mean every once in a long while. I can’t believe the occasional, delicious, burger binge would bring my average up to three quarters of a pound on a per-day basis.

Have I made an obvious math error? Am I eating less like the average American than I realize? Anyone have more insight into this statistic?
