I still don't get how bottled water became a thing. It wasn't a thing when I was a kid, and somehow the industry convinced us to buy huge quantities of an inferior product for more money, and it pollutes the environment to boot. Insane. The least you can do is use a refillable container. 10+ years ago Google switched from bottle water to giving everyone a container. And that was a great move. Yet people complained, a…
Soda, juice, etc. were sold in bottles which normalized it.
Then people wanted to be healthier and so putting water in a bottle at events/meetings felt like providing a healthy choice to people, directly next to the unhealthy choices. Plus the water in small bottles could be kept cold in ice more easily. Also sparkling water already needed to be in bottles, so it seems even more natural to have still water next to it in the same way too.
People in some parts of the country also realized the bottled water tasted better than their local highly chlorinated tap water. (Other parts of the country there's no difference.)
The industry didn't even have to convince anyone. It's genuinely consumer-led.
And refillable containers have their own disadvantages. It's not always easy to lug one around the office as you juggle your laptop and documents and phone, or you forget it in another conference room, etc. It's easy to keep in a backpack, but people aren't usually lugging their backpack to every meeting or to the cafeteria.
I'm not defending single-use water bottles... but sometimes I do wonder if all the materials+energy spent on refillable bottles has actually turned into a huge net loss, as so many of them go unused, lost or thrown out long before they'd achieve a net positive.
