If you don’t know anything about oil companies, you may be missing big parts of the climate change conversation. Individual actions, even from rich people, do not invalidate the points they make. Attacking them on those grounds is part of a campaign by the oil companies to make you and I fight people who are not the root cause of the problem. Don’t be taken in by it. A small number of large companies are responsible for the vast majority of omissions, and even many rich individuals changing their behavior have no impact on that.
