Anti-Vegan Myths?

Although, by no stretch of the imagination could I profess a commitment to 'veganism', I must admit that I found the recent article debunking 18 anti-vegan myths pretty convincing (https://www.theguardian.com/environment/2020/jun/19/why-you-should-go-animal-free-arguments-in-favour-of-meat-eating-debunked-plant-based). There is no doubt that the planet (and we folk living on it) is paying too high a price for its meat and dairy production.  Negative impacts include methane (a very potent 'greenhouse gas') production from burping cows; utilisation of massive tracts of land to grow monocultures of plants to feed to cattle rather than people; losses of carbon capturing vegetation; environmental destruction et cetera. There are also serious health concerns associated with an over-consumption of (especially red) meats and dairy. I can see no good reason why one wouldn't want to move to a diet that wasn't more plant based. The myths appear to be largely invented (sometimes using creative accountancy) by folk with vested interests.
