I don't completely agree with that

Seeing we have twice the number of cattle as people already, I think we will be OK. Besides, for the most part, cattle replaced the buffalo in the prairie ecosystem.

And even if he could our domestic cattle come from europe

And you can *guarantee* there will be no escapement? Accidentally or on purpose? No eggs transmitted by birds? You can *guarantee* that?

There is no guarantee at anytime whether they introduced bass or not that there will not be a transfer of fish, eggs , accidentally or on purpose. Just as there is no guarantee of no transfer of any animal or plant at anytime. If you think there is a way to guarantee this then you do not live in the real world
