I disagree that these things have a negative impact on the world when you or I do them. I think that if billions of people do them, we have issues, sure. But

I disagree that these things have a negative impact on the world when you or I do them. I think that if billions of people do them, we have issues, sure. But there is a finite carrying capacity regardless of what we do. We could live plugged in like the Matrix and there would still be an upper bound somewhere. It is patently nonsensical to take the behaviour of one person or even a million people, scale it to 8 billion, and then claim that it's unsustainable as a result. We have plenty of mechanisms to prevent that from happening. One obvious one is that, as a Brit, I'm legally not permitted to move to the US and live in the same way that someone in Arizona does, which puts a cap on my lifestyle. Most people are in situations like that - ever heard of the "golden billion"?
