h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I've just posted to two SEx threads: "Cloned meat" and "Wind genarators & Infrasound", with an apology for upsetting some people:
-----------
"On re-reading, it seems that I was prone to Telling rather than Asking, where I have only weak foundations.
I apologise for being over-enthusiastic.
I shall also post to my journal."
----------
In "Cloned meat" I expressed my concerns about cloned plants (post 50) and later (post 54) extended it to side effects of GM foods.
---
Based on what I believe to be true:
-
Cloned plants: My concern here is that, given the large-scale propagation of plants by 'growing from cells', there's a possibility of repeating what happened with Elm trees in UK. That is, reducing diversity by 'swamping' areas with clones.
-
GM: Here, it's introducing alien genes into organisms that have established themselves in their environments over long time periods.
It's Not the resultant food, as I can be fairly sure that it's been thoroughly tested.
It Is the possibility of (even minute) side effects that may not be noticed for some time.

Whole ecosystems are dependant on the relative stability of their constituent members and can be affected by tiny changes.
In the 'natural scheme' of things these tiny changes are coped with and become absorbed into a 'new order'.

GM, however, seems different. This is Not a slow process of one, or perhaps a few, mutations at a time, with generations of adaptation to follow.
It Is a wholesale implantation of a fully developed trait from one organism into another (completely different?) organism, in a single generation, with no settling-in time.

It may be (probably is) that it's all been carefully thought out beforehand - but that still leaves room for unforseen consequences.

Tiny causes can grow into large effects - the butterfly effect?

I'm not asking for GM to be stopped - the benefits are likely to keep increasing.
I was hoping to be told that the expressed concerns are recognised within the science and that these aspects have been taken into account.

Wind generators & Infrasound

Infrasound can cause actual physical problems, if it's very loud (that doesn't cause me conern as design should have removed that danger).
At moderate levels it can cause various discomforting effects.
At low levels - if it continues for long periods - it may do.
Apart from any physical effects on us, it could cause hearing problems in animals, some of whom have hearing ranges extending beyond ours (elephants are one example).
Sea creatures, too may be affected (whales, for instance).

Wind generators are of such a size that, despite careful design, they are likely to 'leak' some low frequency sound waves into the environment.
It may be that the extent and loudness of those leaks are not predictable.

Again, as we don't yet know the effects (& may not for some time), some caution is, surely, in order - ?
