Our world by Ronny Cortez Cisneros

1. If you use more the public transport, you won't pollute the environment.











2. If you have an uncharged battery, you will throw it in a special bin.















3.  If we walk instead of driving, we will get  the levels of the CO2 in the ozone layer down.














4. If you use wind power, you will save the energy.

5. If we use the bike, we pollute less and do exercise.
