Chapter One

The Boy Who Lived

The chapter starts with description of the Dursley family, who are proud to be "perfectly normal". We learn that Mrs Dursley has a sister, Mrs Potter, but their families haven't met for several years. Both families have sons.

Then the story begins on a "dull, grey Tuesday". Mr Dursley notices a lot of strange things hapenning - owls flying in town, people in cloaks, a strange cat sitting on the wall of his garden, unusual news on TV. The Dursleys go to bed wondering what it all could mean. At night, a tall, thin and very old man appears near their house. It's Albus Dumbledore. The cat turns out to be Professor McGonagall, and the two are professors from Hogwarts, a school of witchcraft and wizardry. Then comes Hagrid, a giant, who brings little Harry Potter. Harry's parents were killed by Lord Voldermort, a dark wizard, but Harry survived and Voldermort's power "somehow broke" .

So little Harry is left asleep on the doorstep of the Dursley's house with a letter written by Dumbledore. The professors and Hagrid go to join the celebrations.

Contaminant - a substance or mixture of substances, the number and (or) concentrations exceed established for chemical substances, including radioactive and other substances and microorganisms standards and have a negative impact on the environment.
Air pollution - a really serious problem. Air is composed of oxygen, nitrogen, water vapor, and, thanks to our civilization, of a variety of toxic particles. The more of these particles in the air is, the less room is left in the atmosphere for oxygen.
   The problem of air pollution is not limited to the space outside. The air inside our homes and offices can be as dangerous to your health. The main source of pollution - cigarette smoke, but it is not the only one. Toxins are allocated even when you just cook. Every time you scratch the Teflon non-stick coating is allocated enough toxins to kill a canary.
 Greenhouse effect, which we all have been associated with the phenomenon of global warming, caused by toxic gases. The main enemy of clear atmosphere - methane. It is released from the decomposition of sewage.
Greatly affects our waterways. In every neighborhood, in every city there drain sewer, storm water from the highways and municipal enterprises directly into the river. Everything goes into the water, passing minor cleaning steps.
