One of the first (and simplest) things I've been trying to move away from is single-use items.
I'm always looking for simple and easily implementable ideas to help me lower my waste footprint, and thankfully, there are many wise people who are happy to share their experience.
A few years ago, we took out the grass lawn in our backyard and have gradually been filling it with perennial plants. No mowing, very little watering, and the best part is that quite a few of these are edible (or have other benefits).
A few small changes can make a big difference when it comes to lowering waste around your house.
