The water problem of Haiti

HAITI WATER PROBLEMS

Haiti its a country located in a very small island that is on the Caribbean sea, and its bordered by the Domynican Republic. Haiti is surrounded in 3 quarter parts of sea, so the haitians have a very little access to fresh water. 5 milions of 8.5 milions of people in Haiti don't have access to clean water. Many haitians suffer *dehydration and other illness caused by drinking poor water, and 1 of every 8 haitians childrens die before having 5 years

*dehydration: not drinking enough water

We can help donating money for ONGs that helps the poor countries.

In Switzerland, near Geneva, we can find the CERN.
Its not a laboratory that produces practical inventions, but in 1989, Tim-Berners-Lee invented the world wide web.
Tim was an English engenieer with computers in his blood: both his partens worked on the first commercial computer made in Britain, the Ferranti Mark 1.In 1980 Tim got a jod at CERN for six months,and during this time he wrote a program called "Enquire Within".
This name comes from a popular Brithis book that was first published in 1856. The book is full of advice and information on all sorts of different topics-from how to clean rom a shirt to how to get married. The Enquire Within was new because it used hypertext, that is a special type of text that is intended to give more freedom to the reader, and contained links to music, other pages..etc.
