Answer 2

The effects are simple. Mass produced non-organic foods contain more toxins (herbicides, pesticides, fungicides and heavy metals). Hybrids between various plants have produced more allergies in people. Control of most of the food chain is now in the hands of multinational companies with more power than our current governments.
