I still drink coffee regularly so am not going to say people should stop doing what I continue to do but it's worth it for coffee drinkers to be thoughtful about the impact of their consumption.
But also apparently producing one meal worth of chicken takes 700kg of water. Over 3000kg of water for beef. So I think, in comparison, coffee water use if negligible.
The overall issue is that coffee pod waste is de minimus compared to the environmental impact of the coffee industry at large.
"You say reducing plastic is good for the environment, but then you drink coffee which is bad for the environment, so you shouldn't bother even reducing plastic"
"EVs still use energy that's been generated from gas, even if its a lot less, so you might as well just drive a diesel powered pick up truck"
It's like stopping using aspirin because "drugs are bad" while doing meth every day
That feels like a pretty wild claim, but I'll happily admit if I'm wrong.
