Composting is something many of us would love to do if we weren’t grossed out by the thought of keeping organic waste (ahem) in the backyard. Luckily, Compostwheels in Atlanta doesn’t mind getting their hands dirty in the name of urban sustainability. In return for your eggshells and banana peels, they produce neatly-packed, nutrient-rich soil to help make local farms thrive. Oh, and they prevent upwards of 6,000 lbs of organic waste from ending up in landfills each month. Check out the soil-making magic.

Like a growing percentage of city residents, George Hinds does not own a car. George walks, bikes, and uses public transit to get around. And when travels take him further, he takes Zipcar. He’s not a millennial. Not a college student. He’s a senior citizen. At 91, George is one of our oldest Zipcar members. And he’s not slowing down anytime soon. “When you live a long time, you get to do a lot of things,” he said. George has had 4 children, fought in WWII, graduated from Yale, taught at the University of Illinois, worked ski patrol for 30 years, and is writing his third book. “I don’t know what keeps you young, but I’m very active.” Yep, we’re pretty sure we all want to be like George when we’re his age.
