There are SO many things we can do to change the world. I will give you a few examples of what we can to to change and save the work economically. First off, we can limit the amount of fuel and harmful gases we release into the atmosphere. We can do this by limiting our transportation, or taking a bus or riding a bike. Also, we can limit the amount of water we are using as well. TONS of water is wasted every single day. We are wasting water when we brush our teeth because we leave the water faucet on, and when we take a shower because we keep it on the whole time instead of turning it off when we shampoo and condition. Another thing that we need to stop doing is throwing trash in the ponds, lakes, rivers, and oceans. Many animals live in those waters, and many die every day because of the pollution, or from being stuck in plastic or so. There are so many other things we can do as well, these are just a few. Hope I helped! (:
