Dear Sir/Madam.
I am writing to suggest to you ways of solving the air pollution
problem in the city. First of all, people should reduce the number
driving their cars and use electric ones. Secondly, we must recycle
and reuse materials and protect forests and parks from fires.
We must also be economical in lighting our fireplaces and use
more filters. It would be a very good idea to plant more trees by
making environmental programs at schools so kids would start
planting trees too and try to build more ecological buildings
instead of factories.
In conclusion ,we could all make some of those suggestions
a part of our life if we want to live in a better city and a better,
healthier world.
Yours faithfully,
Panos Zekios
Excellent!
