few ideas: Organic farming and the back to basics way of farming without the use of chemicals and pesticides and sometimes even without machinery for the sake of our earth and our own health. or Look at the genetic altering of different foods. This technology is ruining the goodness of the original heirloom varieties of so many fruits and veggies. Or the use of hormones and antibiotics in the animals we eat and the conditions and unhealthy circumstances they are being raised in. We consume these things when we don't eat organic meat. These things are terrible for us! Hope you can use something here!
