2. Taking a short shower instead of a long bath. It takes about 25 gallons of hot water to fill the bathtub, compared to only seven gallons for a quick shower.

3. Use cold water in the washing machine. Hot water won't get the clothes any cleaner, and it wastes a lot of energy.

4. Turn off the tap when brushing your teeth. You can save up to 8 gallons of water a day. That adds up to more than 200 gallons of water a month wasted.

5. Use a sponge when washing your car. A hose can waste 6 gallons per minute if you leave it running, but using a bucket and sponge only uses a few gallons.

Costa Rica is one of the most sustainable countries because of its dedication to their forest and water systems in the country.

Austria is only 84k square kilometers and hosts a population of almost 8 million people. Of this area, 46% is forested land.

2. Recycle. It reduces the amount of trees we need to cut down for paper.

3. Get a reusable water bottle instead of a disposable bottle. This saves an enormous amount of plastic.

4. Don't litter. Litter will pollute the earth and this isn't sustainable.

5. Buy sustainable foods, don't buy food from companies that don't farm or catch their animals in a sustainable way. It will have devastating consequences.
