Letter: Do not overlook travel’s contribution to climate change

PORTLAND PRESS HERALD • August 18, 2025

Thank you for the recent article elucidating how better we can focus our efforts to reduce greenhouse gases with its emphasis on reduced air travel. This has not been a subject of much discussion, despite its being the most destructive thing we can do as individuals (tied with cruises). The U.S. government’s policies now exacerbate the problem, therefore we must take a more active role to save ourselves, future generations and other species in danger of extinction. The U.S. is the country most responsible for the climate change emergency. ~ Joan Stanton, South Portland
