Here’s how to live with the environment in mind

Don’t worry— this is easier than you might think.

Stephanie Hayes Richards, managing principal of Gnarly Tree Sustainability Institute, told WalletHub about simple, cost-effective ways people can be more eco-friendly in their daily lives.

“Some easy ways individuals can reduce their environmental impact while saving money include turning lights off any time you leave a room for more than one minute, installing energy efficient lighting, trying to keep your thermostat around 78 degrees in summer and 68 degrees in winter, avoiding the purchase of bottled water, turning down the water heater setting to 120 degrees, taking shorter showers, buying house supplies in bulk, trying to eat vegetarian protein sources at least a couple meals each week, and combining weekly errands as much as possible to reduce gas usage,” she said.
