This is another perfect example where these organic and green zealots think the local ma and pa store down the road beats Wal-Mart in terms of efficiency, emissions, and health.
I know you leftists hate large and successful companies. I know you hate lower costs and genetically modified food that has resilience to disease and plague. I know you all want to live in teepees and get back to one with nature.
But in the end economies to scale, efficiency, technological advancement and (GASP!) CAPITALISM beats, hands down, an irrational zealotry to pursue "green" or "organic."
Besides, just admit it. You don't really care that it's green or organic. That's just marketing.
