A letter written by studentsS. Cosmado Primary School, 4th April, 2011

Dear Mr. Manuel

Our little letter should surprise you, but we have to explain it.

We are part of a group of international schools, of almost, all European countries,that belong to the Comenius Project with the theme of water.Some days ago, we were walking around to gather information for our work when wenoticed that your tank was abandoned and covered with all sorts of household waste.We were alarmed and decided to discuss the issue at our school. That was when wehad the idea to warn you, asking some questions so you can reflect on them to takeaction.

So here are some questions:

- Have you ever thought about the harm you are causing? Are you aware of theproblems that water pollution brings to all living beings? Did you know that there areenough dangerous materials to the health of us all? And that contaminated water willkill birds and plants that serve as food for other living beings, including humans? Areyou aware that in less than 25 years, if we continue to destroy the water withoutreusing it, there will be no drinking water for our children? If there are survivors,

they will be ill, sad...

Do you remember what happened to Chernobyl? Have you everwondered what would be like to live in this ghost land wherehumans do not survive? What about living in the desert withoutwater? Have you ever wondered why millions of people walk lots

of miles every day, just to store some water to feed themselvesand for their personal hygiene?

Stop and think about it!

Do you remember Mr. Antonios tank, which, just a few yearsago, had fish jumping through the green, but with the trash theydid not survive and died?If people continue to be selfish we are all going to die of thirst,malnourished and ill.We are sure you will take account of our sufferings and will

change your attitude for the good of all.

Sincerely,

Students and teachers at the S. Cosmado Primary School
