Brit. Facts about GM foods, archive 455

Given that at least some of these facts aren't true, I have wonder
about the truth of the others! 


>INDEPENDENT (London) November 30, 1998





>Seeds genetically engineered to kill bad pests may kill the good

>too, eg: potatoes which were engineered to kill aphids also killed

>beneficial ladybirds.

As I have said often on this server, these plants were experimental and
have little chance of every becoming crops.  


>In the US, . 1 million acres of GM cotton which was supposed to be
resistant to

>bollworm was destroyed - by bollworm in 1996.

This is laughably not true; one million acres would have been most or
all of the crop! 


>In Nebraska, cattle farmers faced a crisis when their cows stopped

>grazing because their corn fields had been growing GM corn and they

>like the taste. 

I'd like to see where this comes from; generally (and certainly in
Nebraska) you don't graze corn with cattle or anything else! 

> In the US a

>disease called EMS was eventually linked to a food supplement derived

Wrong again?  Has anyone bothered to follow-up on the following posting
from some months ago?
