Great write up. I think in general genetic engineering can result in positive benefits, but we must remember we should do it in a slow and controlled way with the appropriate controls. the last thing we want is a super bacteria that resists all antibiotics because of the lack of controls in the genetic engineering process.

Also this article got me wondering whether we could genetically engineer organisms to efficiently soak up CO2 form the atmosphere, and then store it somehow? Well that's what plants do anyway right? probably there are people working on this already...
