Scarrier to me than Bt in Corn

[Barb Beck]

They have introduced the gene from Bt into aspen up here in the
great white north.  Turn that loose in our boreal forest and it will
really cause havoc.  It would be an "exotic" able to outcompete our native
trees because of the ability to ward off attach by catepillars.  

At least if people desire the problem with corn can quickely be stopped
but eradicating exotic aspen in the boreal forest would be another matter.
