Me, I can’t help thinking about all the unused bits of land I see when I drive around.
I see a park, and think “why don’t they plant some fruit and nut trees there?”.
I look at the long strip of grass between the dual carriageway, and wonder how much corn or grain could be grown in there.
I see the long grass growing alongside roads, and wish I could come along and scythe it and take it home for composting.
I see an empty lot with a boat parked on it, and wonder who owns it and why they haven’t done anything with it for the past 30 years. Surely they could have just thrown some useful trees on it and be basking in a productive food forest by now? Or even planted a stand of fine cabinet timber and be harvesting tens of thousands of dollars worth of wood?
When people tell me we need genetic engineering and factory farming because we don’t have enough arable land to feed ourselves otherwise, I wonder if they can even see all the wasted land around our towns and cities. Surely they can’t be that ignorant?
