4. Stand up, hold the hands of your partners, stretch your arms as wide as you can. Now
imagine that you are trying to reach from pole to pole. Do you know what the distance is
from pole to pole? It is more than 15.000 kilometres. They say it would take 12, 5 million
people holding hands to stretch from pole to pole. It's rather impressive, isn't it?
For thousands of years the Earth has given support to all forms of life – human beings,
animals, birds, fishes, insects and plants. Many years ago our planet was very beautiful,
without any environmental problems.
And now our great, beautiful planet is in danger.

P1. I want to tell you about water pollution. The situation is really gloomy and
sometimes even hopeless. Rivers, lakes, seas, oceans cover more than 70% of our planet.
Scientists say “man will die if oceans die”. Over 5 million tons of oil products pollute the
ocean each year. About 2 million tons of these products come from cars. First the oil
products go into atmosphere. From the atmosphere they go into oceans. A ship wrecked
tankers spill a lot of oil into the ocean. In addition big rivers carry into the ocean a lot of
waste from industry and agriculture. Pollution means death to oceans. It kills fish, plants,
birds. Experts believe life in oceans will be destroyed within 25 years.
