butterfly releases

[Michael Gochfeld]

The issue of Butterfly Releases seems to get revisited annually with
about the same result. 

But in response to some recent posts one could turn the questions
around. Why should one have to prove that they are harmful instead of
putting the onus on those who profit from the releases and should have
to prove that they are not harmful. 

After all, this is the approach most people would like to see used with
biologically engineered organisms.  Why not with butterflies.
