I’m gonna start going ‘less-meat’ in a couple of months once the wife is done breast feeding, I.e. don’t just go for it with every meal but have it as a treat instead.

Meant to reply to your comment before, Topbin. In principle, I agree. A couple of observations on all of the meat vs vegan mullarkey.
There's an oft-quoted statistic somewhere to the effect that the human race would need three planets if everyone consumed resources at the rate of the 'developed' world - ie our continued lifestyle is contingent on an awful lot of people consuming significantly less.
But I read a blog recently (can't find it now. typically) suggesting that a lot of stuff written about veganism wildly overestimates the availability of land for crops. There are various (typically arid) parts of the globe where the human diet is pretty much meat dependent: we need animals to convert scrub plants we could not digest into meat we can. So I s'pose the point is that the world could never be vegan - at least not without a massive population drop - but we need to figure out how that meat is best produced and who gets to eat it.
I think the most efficient farming nation on the planet is the Netherlands, and that's because they've committed huge acreages to greenhouses. Crops grow under glass all year round, use less water and less volume of pesticides. I think we need to head the same way. Maybe serious consideration should be given to red meat rationing.
