Environment & jobs

The standard response to proposed environmental improvement such as CO-2 limits, is that it raises cost and reduces jobs. Cost of any action is always there, and new laws don't create them, they just change who bears them. As for jobs, markets are designed to allocate resources to their best use. We have been substituting natural resources for labor for a long time. If we increase the cost of natural resources, it should result in more demand for labor over time.
