Save trees. Trees save.

My wife and I encourage our kids to reduce, re-use and recycle. We teach them to care for the environment. We teach them to value life - no matter how small.

My kids have organized recycling campaigns. They've made posters to "Save the Earth." They've helped with returning cans and bottles.

I think that they'd like this un-sourced advertisement. It's very understated and yet very powerful. It simply says, "Save trees. Trees save."
