the meth addiction.

I was recently with a farmer who was talking about a new kind of farming, healthier for the land, more efficient, more cost-effective even, and it involves no chemicals. 

His mentor, however, told him this: Be careful weening your ground off of the chemicals too fast. The soil is like a meth addict. It's addicted to everything you've been putting on it and it's going to need some time to get off that. 

Our land is addicted to drugs.
