And who bought the gas? Who bought the oil? Who bought the plastic made from the oil? Who bought the food grown from the fertilizer made from the oil?
If you don't live on North Sentinel Island your entire life relies on the products of the corporations that have destroyed the environment. You are complicit. Your parents were complicit. Your children, if any, will be complicit.
Blaming corporations or capitalism or "big oil" is just a way of dodging personal responsibility. It's an excuse for not making inconvenient personal changes in your own lifestyle. It lets you tell yourself that when big corporations consume so much there is no point in you lowering your standard of living to consume less.
The fact that corporations are worse than you does not absolve you of your responsibility for your own decisions and your own environmental sins. We all have to do better.
