The recent debate over cap and trade in Oregon was intensely emotional, causing some senators to actually go into hiding to avoid voting on it. I suspect the emotion driving both sides was fear.
Those promoting cap and trade fear the long-term consequences of a warming planet. Those opposing cap and trade fear the more immediate losses of their constituents’ jobs, income, and way of life. Their fear is not surprising, given that people tend to worry more about losing something they already have than what they might not have in the future.
The irony is that none of us will live to see the long-term consequences of our actions, so we don’t really know for sure how they will impact the future. We are the ancestors of the people who will have to live in the world we leave them.
