UMN's Organic Ecology website. The presentation, titled Why Eat Organic, provides a wealth of information about why organic agriculture can feed the world, is necessary to mitigate the effects of climate change, and can undo a lot of the harm that conventional agriculture does to our bodies. Not only do organic foods contain far less pesticide residues than their conventional cousins, but organic foods also have higher levels of healthy nutrients. Children who go organic for just five days "can virtually eliminate exposures to a dangerous class of insecticides known to disrupt neurological development in infants and children." Additionally, many of the nutrients found in much higher levels in organic foods can greatly decrease your risk of heart disease, diabetes, and many cancers. Organic is not only the safe bet but the healthy bet, both for our bodies and for our planet.
This presentation gives a great overview of the organic movement, but if you're looking for a more in-depth compilation of many scientific studies, visit Iowa State University's Leopold Center website.
Have a great afternoon!
