No. Hunters will pay for the opportunity to hunt, just as they do now. The venison aspect is a red herring - there is no way that you could create a market-supply system linked to conservation, as both have competing agendas. Hunters and markets want lots of deer and a regular supply. Conservationists want much reduced deer populations. Even now, when deer-shooting syndicates are invited to cull deer for conservation, they eventually reduce the population to a level where it's not interesting/worthwhile/enjoyable for them after a few years. So voluntary effort declines, and deer numbers can build up again. And then you have the problem of food safety/quality guarantees. Very large, and ongoing - the guesstimate is 750,000 animals per year to keep the population stable, so that means closer to 1 million for a reduction. It is not going to happen on that scale. Exactly. What is totally missing is evidence of what the optimum number of deer actually is, and quantification of what damage a given density of a given species creates in a given environment. So far, it is all assumptions.
