When Food52 set out to create 30 days' worth of tips, stories, and guides for how to live eco-friendlier every day, there was one topic their whole team couldn't stop Slacking about: $0 ways to go green.

From the kitchen to the farmers' market, here are the highly doable, no-cost ways we can live eco-friendlier today.
