In order to live on this Planet without boycotting future human generations, we need to be conscious of what is the story of our stuff. Yes, this could be a first step. Afterwards, we can look for alternatives and to acquire the things that exert the least negative effect on the resources that we require to live (like water, air, climate regulation, oceans, forests, etc.,) and other humans beings around the Planet. Eventually we can even evolve our own lifestyle to whichever fits us, and is in tune with keeping our species on this Planet.
Whatever our story ends up being, if you care enough, like I said a first step could be to learn the story of our stuff. Internet so wonderfully makes this easier, and Annie Leonard and co. make it even easier, simpler and fun.
