I agree the straw thing is silly and arguably even counterproductive. It makes people feel like they are doing something when in reality it makes very little material difference. "I sacrificed with a paper straw. Now excuse me as I go buy some clothes I'll only wear once". But you almost certainly use things from those 100 companies. Which of their services and products should we deem worthy or not? Maybe a carbon tax is the way to go. But then which things should be more expensive (rarer, less available to the poor) and which ones should be cheap (common, available to the poor)? It's all tradeoffs and it's complex.
