Living outside the US - shocked at our waste

I spent a good deal of time living outside the US this year and I am now shell shocked at how wasteful this country is. When I got home, I cleaned out my entire closet and donated about 50% of my stuff. I am going to try to get rid of more stuff this summer. Basic things like making products easily recyclable or reusable is just not a thing here in the US. The sad thing is it can be done, our companies and citizens just choose not to push for it or do it. While I am not sure I'll move out of the US (I know this is a major privilege), I definitely plan to change my consumer behavior. I am also trying to walk more and use my car less.
