This is a great story from Science Friday about corn. The author of “Omnivores Dilemma”. Corn is in almost everything we eat, and our carbon is from corn.
A bushel of corn is 56 pounds of 20% of oil consumption is for food growing, more than for transportation! Corn is over produced. And the government subsidizes corn production to the tune of 50 cents a bushel.
There is a dead zone size of NJ in the Gulf of Mexico caused by nitrate fertilizer runoff from Iowa!
Listen the audio. I might try to read the book.
Basically the message is: we make choices that support the cultivation of corn to the exclusion of other healthier choices.
