DEARBORN, Mich. — As more than a billion people observe Earth Day by participating in activities to protect the planet, AAA-The Auto Club Group is sharing ways Americans can do their part while traveling.

— Reduce carbon footprint by bringing reusable water and toiletry bottles;

— Be mindful of energy and water usage by taking shorter showers, reusing bath towels, and keeping heat/air conditioning at moderate temperatures;

— Travel during the off-season or to less popular areas to limit infrastructure challenges created by over-tourism;

— Shop and eat locally to support the community;

— Purchase locally made souvenirs (preferably handmade) and pay a fair price;

— Honor local customs and immerse yourself in the local culture;

— Donate to an organization or plan to volunteer.

All these activities are examples of sustainable travel, a concept that focuses on how to maintain travel and tourism without hurting or exploiting natural or cultural environments in the process.

This includes using the revenue generated by travelers to benefit destinations and the people that live there. It also means being conscientious of the resources you use and how your behavior can affect the places you visit.
