Really good article by Ronald Bailey over at reason about transgenic technology. I respect Bailey, I have even read some of his books on the subjects of environmentalism and transgenics, but he usually produces light-weight work for reason rehashing his old arguments; eg "genetic manipulation has been going on for centuries" etc. This work is well-thought out and well-researched answer to the anti-scientific left (and yes, they are the big threat to using technology to improve crop yields and fight diseases) which brings up specific examples. Enjoy!
