Well you shouldn't say "These bad bad companies are solely responsible for the climate change, I don't need to do anything because in relation it doesn't matter anyway." But that's about it. Companies and rich/powerful people are the main reason for the climate change. Just take the "carbon footprint idea" created by oil companies in the 60s to shift their responsibility to others. Big companies know what they're doing. Additionally, don't underestimate marketing and advertising. They have the power to create more "needs". You may be proud of your goals in restricting yourself and you should be! But the world can't be saved when every consumer is doing their best while companies doing what they're always doing. I don't wanna say capitalism is completely bad, we just need an advanced long term focused version of it.
