What evidence supports or undercuts stiffer actions to protect the air? Explain

Question

What will be an ideal response?

Answer 1

Against stiffer actions: the air is much cleaner than it used to be, so action is not
urgent; it increases consumers' costs; these actions interfere with free enterprise; regulation
hampers competitiveness of businesses; regulations impose more of a compliance burden
on smaller firms than larger firms with more resources; regulations disproportionally harm
the rich, who invest in business that employ the poor; regulations disproportionally harm the
poor, who are less able to switch suppliers.
For stiffer actions: people's health is still adversely affected by emissions; people's
property is still damaged by emissions; costs of remediation are much less than cited by
opponents (see, for example the discrepancy between industry estimates of compliance with
the CAAA and the actual costs); trees and wildlife are still adversely affected by emissions;
crop losses are due to emissions.
