permaculture

[Marimike6@cs.com]

Birds already illegally transport themselves from one continent to another. 
It's called "flight". That's the way a strain of flu native to south China 
and 
Vietnam has suddenly turned up in Romania, Turkey and Russia. Unless we put 
the country under a dome, in time wild birds will carry this strain to 
domestic 
flocks. 

The practise of confining huge numbers of poultry into overcrowded factories 
might actually retard the spread of avian flu, as no self-respecting wild 
bird 
would be caught dead associating with such flocks. But free range poultry 
would be at some degree of risk.
