The 3 Rs
Imagine a hierarchy: R-R-R. First, stop buying (Reduce). If you have it, keep using it (Reuse). If it breaks, give it a new life (Recycle).
Greenhouse Effect
Think of the Earth as wearing a blanket. Greenhouse gases are the wool that keeps the heat trapped inside. Too much wool makes us overheat!
