Forget About an Antarctic Reserve?

The proposal to get International agreement to designate a large reserve in Antarctica with benefits to the organisms in that area (and outside it) has apparently been rejected after opposition primarily from China, Norway and Russia (https://www.theguardian.com/world/2018/nov/02/plan-create-worlds-biggest-nature-reserve-antarctic-rejected). It really does appear to be very difficult even to stop people exploiting some of the last semi-pristine areas of the planet that are not even within their borders. The prognosis for protected areas within their own (and other countries) land masses appears even worse.
