There's a balancing act between economic health & environmental health, since that also impacts our long-term economic health. But again, that's a different question and the end-result really depends upon priorities. A thousand people can have a thousand different opinions on how much we should really do, if anything.
I prefer to stay focused on the science though, which should inform the policy. There is no doubt whatsoever that human burning of fossil fuels is the primary driver of recent climate change.
