mrgrackle, there are several published research papers about BSF and not one of them suggests that BSF represent a risk to the environment. I don't take anyone's statements or lack of statements as proof, but I have a hard time believing that all of these scientists are ignoring or denying a noteworthy risk.
I've personally looked for the problem you warn about and have found no evidence to support those fears concerning BSF. If you can find any indication of a possible problem that BSF might cause in any part of the world please share that information with me.
