Finger pointing at corporations while doing nothing may not be as bad as corps finger pointing at us while doing nothing. But it's still bad.
Everyone needs to make an effort on this.
Hoping corporations will somehow grow a conscience isn't accomplishing anything.
Imagine if nearly everyone was using public transit instead of voting out politicians because gas prices got a little too high. That might make the corps think there was more money in green energy than drilling up more oil.
Corporations are not going to fix the problem out of the goodness of their hearts no matter how much people whine about it. It's only going to happen when voters (and consumers) demand it.
To add to this, corporations are made of people and selling to people, and most of us are either working for them, buying from them, or both. Everyone needs to change and put social pressure on everyone else to change, this is how groups of people will change, including companies and the governments that will only change as the result of the voters' pressure.
That's the idea yes, anyone who lives with modern comfort is guilty, of course some are more guilty, especially the ones who have the money and the education to reduce their footprints but don't.
