Beeswax is perfectly acceptable but it costs more and I don't have the numbers but there is probably not enough bees in the world for all those starbucks cups.
The unpleasant truth that nobody wants to hear is that the only way to solve this is to ban all these disposables and use ceramic cups in the cafe or bring your own flask.
Everybody is an environmentalist until the environmental policy bothers their sense of convenience.
I think the fundamental problem is plastic is cheap and companies have zero need to factor in the environmental costs. It's pointless to blame the consumer for buying something that they can afford, these products that do terrible damage to the environment need to be made unaffordable through taxes on the companies producing them.
Consumer sentiment alone will never make a significant impact.
We really need to stop blaming individual people for not doing their part and start blaming the system for having the wrong incentives.
Why not both?
Yes, we definitely should fix the incentives wherever possible, because many people are just going to blindly follow the incentives. Those who don't will often get outcompeted by those who do.
On the other hand, if ethics does not mean "do not always blindly follow your incentives", I wonder what else it might possibly mean.
It used to be that conspicuous consumption was frowned upon, I think that was probably a good thing.
I tried it once! You start to see pools of wax float to the surface of your coffee.
