I am not sure if I am the only ignorant person out here. I am well aware, that I am ignoring any statements about that technology being safe, because this isn't about some tech being safe or unsafe (most technologies can be used both ways), its about risk:

The problem I have, is that nobody really knows what happens when you place those products in our ecosystem. We might have some theories and observations but in the end nobody knows enough about the whole system to understand all its processes and sometimes small changes have much larger effects.

And as long as we have only one system and no backup, I don't want to risk changing the ecosystem on this planet in ways we can't predict.

They have been growing GMO papaya in Hawaii for 26 years (20 years commercially) now. Nothing happened.

It's all "unknown unknowns" territory here. There are no known threat scenarios. But if you're into being concerned of unknown unknowns, you have thousands of other things to be concerned of, too.

Well, risks are always about probability of occurrence and impact. So while it is unlikely that some GM plant causes some catastrophic scenario, but when it does it is likely to spread so the impact would be big.

I know that unknown threats are everywhere and there are a lots of other things I am concerned of too, but in the end I am used to live with that and it doesn't change my view on the topic.

More like if ever it spreads to a place that is not some other farmer's field. Even unmodified plants have problems with that and modified ones might be terminator or less viable crops too.

The WHO would probably be a big fan of anything that feeds the hungry masses, so what do they say? America sells GMO, so they could have some bias.
