GMO's

A WebMD doctor's review of the literature shows that the safety of GMO's is unknown and there are reasons to be apprehensive.

For the record: on this issue, as in many others, proof is unnecessary for action. The point of the article is that it is reasonable to doubt the safety of all GM food. I happen to know that WebMD is extremely careful to only make medically defensible claims in their articles, because this is crucial to the market value of the WebMD brand. So until I learn more and otherwise, I'd rather play it safe, within a margin of practicality (affordability), especially with the developing bodies of my children.

A little context

There's at least 100 billion stars in our galaxy, and at least 100 billion galaxies in the universe. You can't picture that, but you can picture 10,000 galaxies -- or rather, the Hubble Telescope can and did. In 2003/2004, it took 11 days worth of pictures of a tiny, "starless" chunk of the "sky", a visual field equivalent to one-tenth of the moon as seen from Earth. The picture spans more space and time than any other picture ever taken: the most distant red blips may be 12 billion years old, and thus 12 billion light-years away. There are a handful of our Milky Way stars, with tell-tale light crosses, getting in the way, but almost everything else here is a galaxy. Each little whorl, blob, and dot: an entire galaxy -- many, like the Milky Way, containing billions of suns and planets.
