7 ton seems pretty big and I think they were warm-blooded, I recon they'll start starving before I run out of food. They may not be dead by day 30 but on those final nights of starving unconciousness you could probably stick it with the knife. Large birds of prey may only eat once per day but they still starve within a couple of days, and the bigger they are, the hungrier they get.

I mean the brief is of you kill it you get a big payout but you otherwise get to live rent free in a hut for month fully catered. As consolation prizes go there are worse gambles and this one at least means you do not die.
