Even if you believe all creatures are equal - which they are not. Biodiversity has value in and of itself and invasive creatures threaten to reduce biodiversity by wreaking havoc with the ecosystem.

No??? I understand you advocate for creatures, as do i working in vetmed, but please dont spread flat out ignorance. Animals are not equal in any way shape or form to each other, thats a human social thing. There would be no ecosystem, everything would die and starve out with nothing to correct balance (as would you) which is apparently what you're advocating for.
