Santorini, a beautiful Greek island, lost some of its shine when we stumbled upon its immense landfill. Bottles aren’t recycled and the trash accumulates quickly on this very popular tourist destination. The landfill reminded us of each small bar of soap, the paper on that soap, the little plastic container of shampoo, the paper, plastic or styrofoam cups (also wrapped in plastic) used by everyone who stays in a hotel each year. The numbers quickly become overwhelming, not to mention a little depressing. For instance, Global Soap, a non-profit organization that recycles hotel soaps globally to improve health in impoverished nations, estimates that U.S. hotel visitors throw away over 2.6 million bars of soap – every day. So here are eleven easy to follow tips for eco-friendly travel that we try to follow and use for business trips, short holidays or a year long career break.
