Change the resources we use. For example, wood is used for paper, toilet paper, paper towels, napkins, cardboard and ect. We use trees at a faster rate then they grow so what’s an alternative that we can use? Bamboo because it grows so much more faster and is more efficient to keep up with us growing as a population. Fossil fuels are a BIG ONE. We use so much for gas and gas basically runs everything. But once we use those fossil fuels they’re essentially gone for good but we can use solar energy and wind energy to help us stop from using so much fossil fuels.
