I don't get why people keep pretending plastic being widely used today is due to some conspiracy instead of it's just better at its main function, even without factoring in cost.
Compared to glass container, plastic ones are much lighter, harder to break, flexible, malleable, .. the list goes on.
In the 1980s, the use of glass containers was more out of necessity than preference. People didn't opt for heavy glass containers to be environmentally friendly; they simply lacked alternatives.
The appeal of single-use (plastic) containers lies in their convenience. Although they are undoubtedly more wasteful, their ease of use cannot be denied. People favor them for this convenience, with their wasteful nature being an unfortunate byproduct. If we refuse to acknowledge this fundamental truth, progress in environmentalism will never be done.
