Public transit is an afterthought in the US because the American automotive and oil industries lobby to keep it that way so people will buy more cars and gasoline.

Reduce demand, reduce supply, first law of economics.

The one thing that scares companies and governments is a well-organised boycott - it’s the one thing they can’t deal with, as has been long-demonstrated.

You just don’t want to give up your lifestyle, and have excuses that have been astroturfed for you to use.

Climate scientists disagree with you, and say that the only way to deal with climate change is for a significant reduction in peoples consumption. You’re just playing the game where you say that companies have to do it, so that they can say that consumers have to prompt them to do it, and you all carry on as though you’ve addressed the question, as the planet burns harder each year.

You’re the idiots people look back on in history and say, why didn’t they just stop doing the unnecessary social things that caused the disaster?

We are how the world is built and what is produced.

Look - I'll offer an olive branch here: You're right that POU is a tiny fraction of our total environmental footprint as a species (10-15% gets mentioned often). You'd be absolutely correct in saying that taking shorter showers is a drop in the bucket vs almond farming in the frickin' desert.

But all that overhead, from mining to manufacturing to shipping to that god-awful clamshell packaging (also made of oil)... Is still only because we demanded that iPhone, those almonds, that Hummer.

Not a single gigaton of supply-side emissions are because the evil manufacturing industry "wants" to make iPhones. They want to make money, and for our part, we can't throw it at them fast enough regardless of how awful their products are for the environment.
