Well, it's not the space rockets etc. that do this. It's the single-family homes with large yards with no apartment buildings nearby, and the ability to not look at wind turbines, and the community that we have managed to cultivate by living in our own detached homes. The things you have to trade to get the reef back are not usually the things you want to trade. Otherwise, we could happily trade those things. It's not like there are that many people making space rockets, after all. The hard part is giving up the things you want, like personal delivery food or a large car with a big road that has no traffic, or a large yard that you water, or living in the forest with two day delivery.
