right, they shouldn't directly be more responsible than consumers, but they should be responsible for the influence that they do have at their job.
obviously consumers are responsible for the pollution they create. just today my son had a fit because a friend tried to use plastic to start a fire. this may not have been the right response, but he knows that burning plastic is bad, and he acted on that.
i have more sympathy with the oil workers because their options most likely are to quit and be out of work. but anyone who studies to work in the oil industry is making a questionable moral choice. (depends on their attitude, maybe they are trying to contribute improvements to make the impact of fossil fuels less damaging. that would be good)
