Thanks, growstuff, for your informed contributions to the thread.
I'd like to be more informed
.
A friend of mine is a commercial market gardener (the one who provides me with veg for most of the year).
He really knows his stuff and writes for gardening magazines and academic papers, so I assume he is some kind of expert. All his growing is organic, he's passionate about the environment and is more or less a veggie himself.
He's the organiser of a community allotment and has his own business setting up allotments for wealthy people who want to live "The Good Life". None of his projects make money - the community allotment relies on a grant from the council and the wealthy customers pay for their own gardens.
He doesn't grow many "normal" crops - most of it consists of unusual cultivars, loved by foodies. He reckons it's just not worth growing mainstream veggies. Consequently, the veg I get from him is always organic and I sometimes have some weird stuff, which I'd pay a fortune for in a restaurant. (I also get veg from my Friday free hand out).
I've had many discussions with him about the sustainability of food and he would agree that the way he gardens couldn't be upscaled for commercial purposes, especially in different areas of the world with different climate and soil conditions.
We can all do our bit, eg, eliminate waste, eat locally and seasonally (which means avoiding soy and quinoa), eat less beef (although that also means less milk/yoghurt, which is a staple for many people), treat our animals better, have fewer children, etc. but we're omnivores and that's how we've evolved.
PS. My friend is the "informed" one - I'm just repeating what he's told me over the years.
