I am glad this on the table here.
There is another sort of action possible, though it might wind up involving civil disobedience as well. And the actions are not much mutually exclusive.
It is possible to largely withdraw oneself from the global economic juggernaut that causes all this. It is not necessary nor usually advisable to attempt it overnight, and it is usually most effective to engage in various sorts of compromises, but a lot can actually be done.
Malls are full of stores selling things none of us need. Normally we need food, water, a modest bit of clothing, less transport than we generally use, and information. For these and lots of status items, we tend to trade most of our autonomy. It’s not a particularly good bargain, really.
For many people, though not everyone, it is not too difficult to have backyard chickens, fruit and nut trees, and a garden instead of a lawn. A lot of people in cities have swimming pools that could convert quickly to rain-catch storage and fish ponds with floating gardens.
These and lots of other things have been done. It’s a lot easier and more fun to do them gradually and to take some time in learning than it is to be forced to do them almost overnight, as Cuba was with the fall of the Soviet and the heightened American blockade in '89.
There’s a bit of an individual learning curve, but these things have been worked out quite well, and quite a lot of information and classes and help is available under titles of permaculture, restorative agriculture, syntropic agriculture, and the like.
It sequesters loads of carbon, reduces use of hydrocarbon fuels as well as cooling and heating fees, provides healthy non-toxic eats and reliable clean water, something corporations and government are both failing to do more and more often. And hanging out in the garden is enjoyable, and way less work than some seem to think.
