Clean air policies are healthy climate policies. As a primary care doctor, I have taken an oath to prevent sickness and to protect human health and safety. As an individual physician, there is only so much medical care I can provide to address the health issues my patients have as a result of breathing unhealthy air in an unstable climate. The only rational treatment is collectively advocating for upstream clean air policies which are also healthy climate policies. History has its eyes on this decade, and the legacy we leave through clean air and climate-stabilizing policies will determine the health of our children and all future generations.
