1) Is society better off with modern environmental laws, or would it be preferable to revert back to the old common law doctrines of private and public nuisance to govern environmental concerns?
2) Tax provisions can impact behavior. Thus, Congress has created a tax deduction for those who purchase a new hybrid gas-electric car. Other countries have cut pollution emission by taxing companies that do emit. Is this the best way in a capitalistic society to address pollution?
