T: Warm-up. Good-morning my dear friends - boys and girls, and my colleagues! I’m glad to see you here at our lesson, because we are going to discuss some urgent problems today – problems of ecology and environment.

So the topic or the lesson is “Why must we bring apology to ecology?” Today we will try to raise the problems of pollution in its many forms: air pollution, water pollution, pollution of soil etc. We will speak about destruction of wildlife and countryside, and shortage of natural recourses, about noise from different vehicles.
During the lesson I want you to think about the problem “Nobody will help us and our planet, if we don’t help ourselves”. So it is time to start.
Suppose you get out of your house on an early April day and see… “Oh, what is it? It’s a yellow dandelion. It looks at you from the ground as if to say “Protect me, save me please!” We all love this flower in early spring. A lot of Russian poets, writers and jewelers devoted their verses and works to it.

And rich countries should help poor countries too. I agree with this, because all people should be equal and have the same rights for happiness.

P3. Sally is worried about pollution, because we are gradually destroying the planet. We are polluting the sea too. She thinks we should all use less energy. If we used cars less, we would not have much pollution in cities. I agree with this statement because cars are also the greatest polluters of air.

When the tigers are killed, their bones are sent to China. There they are sold for thousands of dollars.
