REDUCE! Reuse Reuse Reuse Reuse Recycle
We need to consume less. Waste less. Not just reuse disposable items (like plastic bags or water bottles); but make, find, or buy (if necessary) bags and bottles (for example) that are actually meant to be used over and over and over again. Unless or until they break. And then you fix them.
Same with every other disposable plastic, styrofoam, or paper item we use. Let's get serious about this, people. There are real consequences to how and how much we consume.
