It’s like George Monbiot wants to reintroduce elephants to England. I just don’t see how it would be possible, there’s not enough space for these megafauna. Though it would be cool to see elephants randomly strolling through our woodland. I think it’s more important first to focus on the species we have lost recently. E.g for the UK Lynx, wolves, beaver, boar. And then if those are all successful perhaps something like this.
