It's sad and hilarious that people hear "zero waste" and think "I need to take aaaaall my cans to the recycling center and compost my scraps", when the waste that is actually destroying the biosphere is the exhaust from your car. If we're talking about "doing lower waste", the first priority is to stop driving a car. Recycling bottles and composting scraps is the thing we can afford to do imperfectly. But not cars, ditching cars is the big important thing and the first step to sustainability.
That one is a bit more about the how rather than the why. HTBUaP gets into the nitty about ruling out less violent action since out industrialist-owned officials haven't responded sufficiently concerns and grievances.
