I'm sure the environmental folks would love it if even a small percentage of the human population started doing that on a regular basis instead of relying on agriculture and industry.
So they can have a couple tomatoes and bunches of arugula to last maybe a month or two after their harvest time? Meanwhile 99% of the food they eat still comes from agriculture.
There really is no real alternative to agriculture and food markets, besides the things that are more of a hobby than a serious option.
You're not wrong, but this is how I learned about in-season vegetables. I can keep my garden going year-round, but it took time and learning, so I'm not suggesting it's possible for everyone (especially once you take geography into account). It's hard work!
But even as a relatively staunch environmentalist, I didn't really "get" in-season produce until I tried keeping a garden 365 days a year. Now it sticks, and I have a much better idea when I walk into a grocery store of what veggies are in season. I should know, because they reflect what I'm currently trying (or know I can) grow in my garden for the given month.
Basically, the benefit isn't just that I'm buying less stuff from the grocery store.
If I tallied up all we spend on our garden and divide the amount of produce we get from it by that figure, it would make Whole Foods' prices look ridiculously cheap...
How long could they survive off their garden and own produced food alone? It’s nice people have their own food production in these small ways. But it isn’t enough.
