The issue is the "extent" of use - the acreage sown.  When BT is used 
strategically, and Roundup is used as one of many approaches to weed 
control, then the chance of resistance developing is very much 
reduced compared to when literally millions of acres are sown to GE 
crops for BT or for resistance to Roundup.  The difference in 
timeline is very great.  So, yes, we are buying time but not just a 
little time.  The BT story is a bit easier to make, because those 
using BT are in transition to more holistic approaches to insect 
control, perhaps involving little or no biocides at all.  The Roundup 
story is less compelling, although I do know farmers in transition to 
organic production systems who are weaning themselves off of 
herbicides via strategic use of Roundup, where needed.

Buying time for what?  To convince people that it is possible to farm 
without dependence on any of these products.  This is not a 
short-term task, but it is certainly do-able.  What will convince 
people, I believe, is not the holism or ecological soundness of 
alternative approaches, but rather, their cost-effectiveness.  Ann
