We have all chosen lifestyles that impact the environment, no matter what lifestyle you live. And that is our choice to make.
Whatever lifestyle you choose to live, just be as conservation-minded as you personally can be and are comfortable doing, while living your lifestyle. I think that is all anyone can ask. Just don't be wasteful. There will always be those people who completely disregard any conservation measures at all as well as those who live such a spartan lifestyle that almost all of us on this forum would not do. I don't think anyone that's posted here is at either of those extremes.
Pointing fingers at other people's lifestyles is not productive as we don't actually walk in anyone else's shoes or know their situation. We only have control over what we personally choose to do.
