Organic vs. conventional agriculture

The new Scientific American blog Science Sushi dispels some myths about large-scale organic agriculture. Here's one example:

Some people believe that by not using manufactured chemicals or genetically modified organisms, organic farming produces more nutritious food. However, science simply cannot find any evidence that organic foods are in any way healthier than non-organic ones – and scientists have been comparing the two for over 50 years.

Better for the environment does not necessarily mean better for you (or for the climate). Not that the environmental benefits are clear either:

Yes, organic farming practices use less synthetic pesticides which have been found to be ecologically damaging. But factory organic farms use their own barrage of chemicals that are still ecologically damaging, and refuse to endorse technologies that might reduce or eliminate the use of these all together.

It's worth a read.
