Bottled water is the fucking problem. Don't whinge about anything climate based if you recommend plastic. The disconnect on solving contaminated water with plastic water bottles s mind boggling.
If you don't have a water source very close plastic beats glass very fast.
Glass is so much heavier that the additional fuel to transport it over 100km offsets whatever emissions plastic creates.
This is the classic "no good option" dilemma depending where you live.
In many parts of Europe you can buy the locally sourced water from glass bottles - but it doesn't make much sense buying glass bottles for climate change reasons otherwise
What are you even talking about? The moral "dilemma" here isn't between water bottled in plastic vs. water bottled in glass; it's between water bottled in plastic and water piped through the damn tap. Tap water is unambiguously superior and it's not even close.
