the environment

First of all, I think that people in "La Boca" pollute because they don´t recycle.
Secondlly,I´m sure that the "Riachuelo" will be a lot cleaner if we don´t waste it.
Also,we must pick up the litter on the street, because when Boca Juniors plays in there are many rubbish later, for example.Finally,I beliave that we need to use renewable energy.
Finally, I´think we have to clean up evrything if we pollute it.
