At this point any ban is no more than a feel good measure. Those particular genies are out of the bottle and getiing them back in is a practical impossibility, unless mother nature gives a helping hand. But of course that would mean catastrophe from an agricultural standpoint so I wouldn't wish too hard for it. Our situation on this is pretty grim as outlined by Martin Niemoeller:
"When the Nazis came for the communists,
I remained silent;
I was not a communist.
When they locked up the social democrats,
I remained silent;
I was not a social democrat.
When they came for the trade unionists,
I did not speak out;
I was not a trade unionist.
When they came for the Jews,
I remained silent;
I wasn't a Jew.
When they came for me,
there was no one left to speak out.
This describes the average American to a "T". Most people don't want reptiles as pets and it takes little encouragement to make them think that nobody should have them. If the concept of "While I do not agree with what you do, I will defend your right to do it" is not reincorporated into the American pysche then it's just a matter of time until they come for the last of us.
