Oh, we have lots of reasons, but this has to be our TOP reason for why we're doing this.
We are completely and utterly diallusioned with our current food system. The governmental agencies that are supposed to regulate it are practically owned - or at least ran - by big ag and corporations.
Case in point, Obama just appointed Catherine Woteki to be the USDA's undersecretary for research, education, and economics. What's the big deal? Well Woteki also happens to be the global director of scientific affairs at one of the biggest junk-food producers - Mars, Inc - and a staunch supporter of GMOs. In her new role, she'll be supervising the head of the National Institute of Food and Agriculture (which oversees grant programs), Roger Beachy. Beachy is openly hostile to organic farming and has strong ties to, you guessed it, Monsanto.
Good grief, could it get worse? Oh it is. More on that later.
