We are living in a time when our food is cheaper than it's ever been in the history of humankind.
The reason it's so cheap is because we have too much of it, and don't know what to do with the monntains of surplus.
Burning is better than plowing it under.
See tagline.
That would be true if it were only the excess that was burned. Unfortunately, we're burning the stuff we could really use. And overproduction is not just the bane of farmers -- every businessman worries about it. I think it's called risk.
