Stop your junk mail with the help of 41pounds, a nonprofit service that contacts dozens of direct mailers to remove your name from their lists.

Don’t waste food. Mom was right. About one-quarter of all the food prepared annually in the U.S., for example, gets tossed, producing methane in landfills as well as carbon emissions from transporting wasted food.
