Saving the planet
(Sent by Silvina Adriana Pajon, a student from Córdoba, Argentina)

I think we all can do something to preserve our environment.

Firstly, we have to stop using aerosols because it that destroys the ozone layer. In addition to this, there are several things we must do in order to solve environmental problems, for instance to find alternatives sources of energy, recycle waste and stop cutting down the forests as well.

In conclusion it seems to me that saving the planet is everybody's responsibility, in particular it is power stations and a lot of factories which cause contamination.
