There may be some evolutionary aspects, but mostly it's a consequence of our culture. When disposable one-use items and containers did not exist, society was fine (for the most part). We would be fine if they largely disappeared as well. What ultimately allowed the shift to occur was that the externalities of disposables were never correctly priced into their production and usage. We can certainly fix that.
