How to protect the natural environment - by Nat Johnson
Using renewable resources and reducing emissions are the two effective ways to protect our natural environment. To start with, we can use renewable resources of energy such as solar, wind or water power instead of burning fossil fuels. By doing this, we can reduce the pollution that burning fossil fuels produces and protect our natural resources. Furthermore, it would be a good idea to reduce emissions by leaving our cars at home and use public transport. We could also use bikes or walk to work or school. As a result, air quality will improve and car emissions will decrease, making our cities healthier and cleaner. To sum up, we should use renewable resources of energy and reduce emissions. By doing so, we can help our precious Earth.
