My family used to have a patch with maybe 30 plants in like 4 sqm of our small out-of-town garden plot. We had so many strawberries! We'd bring home buckets at a time and make jams for winter. It was great.

Now I buy maybe 1kg / year because they are so expensive. After the experience of growing our own food some 25 years ago, I can't justify the current prices at all. Unfortunately, I currently suck at gardening on my balcony, but it's a learning process.

I guess what I'm saying is... We humans don't actually need all that much.
