Without a wanting to be termed a scaremonger, the honest answer is, “We just don’t know whether such GM organisms will have any effect on US, fish or the environment.”
What I can say with absolute certainty is that it’s up to those who design, make invent, etc, such products/organisms to prove they are safe, it really isn’t up to us, or the scientist like myself to prove they are not. This is known as the “Precautionary Principle.”
A principle I will defend to my dying breath, because, sadly history is littered with products that at first appeared to be “Safe.” Only to be found 20-30 –50 years later they were not! Some of which, have turned to be very dangerous to man’s health, fish/aquatic life and/or the wider environment.
To those who think they would not let then be used, sold, consumed, etc, I say wake up and smell the coffee - Asbestos, coalmining, DDT, heavy metals, washing up liquid the pill, infected beef, blare! blare! blare!…. all of which are a legacy impacting on man, wildlife and/or the environment.
Again what I can say with absolute certainty is, once the GM genie is out of the bottle it CANNOT be put back in!
Therefore it up to those who design, produce make such organisms, to prove beyond all reasonable doubt, they are SAFE!
Not for use to prove they are not!
I’d ask you to think on one final point - one Co tells us, its crops are pesticide ready and therefore it needs less pesticides using on it. That when turned around, means, it’s organism(s) is/are resistant to that certain pesticide. But does not say at what threshold level that pesticide becomes both a dangerous to man and the environments heath.
In short, anything that is resistant to something means it can, and probably would take far higher levels than is good for things around it.
Now I don’t know about you, but I find this fact somewhat mystifying, given that such claims can and are be made????
