Recycle
You know what they say, “One man’s trash is another man’s treasure.” Recycle paper, plastic, glass, and metals so they can be sent to a sorting facility and and converted into new materials. Just be sure to take note if you live in a state (like New York!) where you have to sort your recycling. The process lowers greenhouse gases, sure, but there are also money-saving tax incentives, bottle and can return programs, and additional savings from reusing packaging—think newspaper, old scarves, and cloth for present wrapping!
