Yup we should normalize gardening and canning. It's a thing my grandparents knew. Their families survived times of world wars, dust bowls and the great depression. They probably didn't have much choice in the moment but even when times got better they kept up a wonderful little garden. Kid me didn't get why they didn't just buy the things they needed.

I love the conveniences of modern farming and I use it every day. But like all big industialized systems they can be fragile. Covid was a huge problem for a lot of indistries and thankfully farming wasn't really one of them. But if it was countless people would have struggled.

I'm not really a prepper or anything crazy but I don't want to forget the lessons learned just a few decades ago- gardening is great and worth the effort.

It makes sense for it to be the same as solar power: just because most of energy generation is done in big facilities and even some kinds of solar generation (such as solar concentrators) can only be done in large facilities, doesn't make having some solar panels providing part of one's needs (or even all of one's needs for some of the time) less cost effective in Economic terms or a good thing in Ecologic terms.

So it makes sense to grow some of one's food, but maybe not go as far as raise one's own beef or even aim for food self sufficiency, both for personal financial reasons and health reasons. That it's also good in Ecological terms (can lower the use of things like pesticides and definitelly reduces transportation needs) is just icing on the cake.

Imagine instead of putting leaves into plastic bags to get shipped to a landfill, or burning, houses normalized having compost piles.

I appreciate your argument but there's no need to throw in a strawman. Leaves in plastic bags have been illegal in most US states for decades. Yard waste must be in paper bags.
