Climate change is real, it is now. As a mother and pulmonologist, I see the myriad ways through which climate change corrodes the health of not just my patients, but my family, friends, neighbors and community. It's not just the rising rates of asthma and allergies, it's the stunted lung development of our children, the effect on our food supply, the poisoning of the air and water needed to sustain life. As ordinary citizens, we can all do our part to push back, either by speaking up or through individual actions that conserve energy or supporting organizations like the American Lung Association. No action is too small. The time to get involved is now.
