Many people buy PC components from Newegg or household goods from Amazon when they might be an entire $5 more at a retail store. The retails store version you can actually see and touch (more important for a bathmat, less important for a video card) and they're shipping in packages of 100 or 500. Stores typically do recycle all their cardboard.
You buy it on-line, and it comes in a box. And those boxes add up, and many of them don't get reused or recycled depending on what part of the world you live in.
Amazon pushes people to buy more through their ecosystem. We're buying more stuff we don't need than ever, and generating more waste than ever. Their dash button felt like the ultimate consumption waste tool. Amazon is pushing us into a world where we are continually buying.
I'd rather we live in a world where we buy more are, fewer goods (with what we do buy being more expensive but durable). What a great world if our cellphones and devices lasted 8 years instead of 2. A world where we could buy independent games and media and know the creators got a full 85%~90% like with Bandcamp instead of the current bullshit 66% they get from Apple/Google/Amazon/Steam/Gog.
A world where we spend less on goods and the goods last longer; a world that lets us spend more on art, could greatly reduce our overall pollution (not just the symbolic and useless measure of carbon) and could help create a more Army of Davids type world where people can legitimately live off their art.
