That is a very niche topic in terms of the Mexican pupfish and I wasn't suggesting that their maintenance ex-situ is meaningless given that there is no natural habitat left to return to. As you know I am very much in favour of these species persisting ex-situ but unquestionably it would be better if there was habitat still left to conserve them in-situ and we have to desperately try to avoid this happening with other species.
Well it is a view that is problematic and my advice would be to try to tackle this bias that you have because it is almost certainly erroneous and misplaced. If we are honest it is largely the Global North that is the bigger problem in terms of climate change and overconsumption of natural resources.
This is true. Many of the early Western conservation figures like John Muir and Aldo Leopold were racist and had a fear of Malthusian overpopulation in the Global South and the accompanying resource depletion, and only in the past few years have I read articles challenging this mentality.
