Impact is equal to population times affluence times technology.
Decreasing human population can help to decrease impact, as long as the smaller population doesn't disproportionately increase its resource use (affluence x technology)
Tech is culture dependent though. You could theoretically go below 1 if it's used wisely. For example vertical farms are less wasteful. But if course that doesn't help if you're buying a new phone every year.
Wouldn't I=PA/T be more suitable then? As tech increases it should decrease the impact of population and affluence.
Anyway, sorry for being such a smartass. Of course it could be reciprocal. I guess what I am trying to get at is that it sounds like people think tech is bad for the environment, whereas actually it's just our culture that's doing it in.
