>roach at u.washington.eduIf you are worried about the ecosystem, its plenty easy to find more pressing concerns (forest clearing, pesticide/fertiliser overuse, etc etc etc) than genetic engineering. Bear in mind that from the conception of recombinant DNA technology to now, there have been no reports of injury or death, or even demonstrable harm to humans or environment, which can be traced to this technology. Compare that to the harm caused by other technologies as diverse as motorcars, hamburgers, and breast implants, and things start to fall into perspective.
You could actually argue that the precision of DNA technology improves the safety of, for example, plant breeding. There have been several instances of conventional plant breeding giving lines which have elevated levels of chemicals demonstrably toxic to humans, often by design (for example, pest resistant potatoes which were so toxic the leaves of the plants caused skin disease if handled). The weird thing is that these varieties may be more acceptable to consumers because they were produced by 'natural' means, instead of using 'unnatural' techniques.
In any case, just because some technique is new, doesnt mean it's bad. Its important for scientists to communicate this I think.
