— Now let’s find more information. Internet can help us to find out what  the British or Americans think about environmental problems.

Учащиеся открывают сайт www.yahoo.com  и работают с информацией, интересные моменты  зачитывают (тексты из Интернета)

—What environmental problems have people got? How can we solve them? What do you think is the first step?

Слайды с изображением проблем

Примерный ответ:

Animals and birds disappear. The air, the water, the environment are polluted. People pollute themselves with cigarettes, alcohol and junk food. То solve the problems people must stop throwing litter into the water or on the ground. They must stop polluting the air. People must stop cutting the trees. The first step to it is to make people think about the problems, to show them on TV or write about them in newspapers.

• I agree with you. That's why you will try to do it now. Make a poster warning people about environmental problems. You may use the text and slogans from ex. 1, p. 40.
• You have done a lot today. We will see and discuss your posters at the next lesson. At home continue your work with the text and do some tasks in writing.

Well done. Was the information important for you, why?

How can earth recover from increased CO2 emissions? Can rocks answer this question? 

The climate change is thought by many environmentalists to be the biggest environmental threat of our time. Reducing the increase of carbon emissions is connected with many difficulties and there are many studies that deal with this topic. One of the most interesting ones comes from the Oxford University scientists who have studied the connection between climate change and rocks.

The conclusion of this latest study was that Earth can recover from high carbon dioxide emissions faster than previously  thought, and that this process takes around 300,000 years after emissions decline.

They have concluded this by studying the effects of climate change that occurred 93 million years ago by examining rocks from locations including Beachy Head, near Eastbourne, and South Ferriby, North Lincolnshire.

The purpose of examining these rocks was to determine how chemical weathering of rocks was able to re-balance the climate after vast amounts of carbon dioxide (CO2) were emitted during more than 10,000 years of volcanic eruptions.

Chemical weathering refers to process where "CO2 from the atmosphere dissolved in rainwater reacts with rocks such as basalt or granite, dissolving them so that this atmospheric carbon then flows into the oceans, where a large proportion is 'trapped' in the bodies of marine organisms. "

By examining the rocks researchers discovered that chemical weathering increased with time, sinking away more CO2 as the world warmed and thus enabling the Earth to stabilize to a cooler climate within 300,000 years, up to four times faster than previously thought.

This study is another proof to thesis that Earth has many "secret mechanisms" that regulate climate and climate change effects which scientists are yet to discover. Perhaps the best thing to learn about our current and future climate is to look for the clues from the past.

What is the best way to save our planet

The best way to help our environment is to develop global ecological conscience and establish a new set of values where our environment and nature in general would rank above money and power. However, in a world driven primarily by the hunger for money such ideas are nothing but a nice dream and an utopia.

The environmental condition of our planet gets worse by the each day; the negative impact of climate change is already knocking on our door, there's also a huge biodiversity loss because many plants and animals are going extinct, water and air pollution is killing millions of people across the globe, and our forests, especially rainforests are disappearing.

The future outlook looks anything but bright, and by the current looks of it our future generations will likely struggle to survive. What kind of heritage will we leave to them? Do they really deserve to suffer because of our negligence and our disrespect towards the Mother Nature?

World leaders worry only about economy and their political interests, while environmental issues usually end up in "wait for better times" agenda. The world leaders still fail to realize that without the right action there won't be better times, and that things will soon get totally out of our control.

Take for example a climate change phenomenon. If only half of that what scientists are saying is true then we are surely heading for the scenario seen only in movies of disaster.

It certainly looks like the world has opted for the waiting strategy. But where is the logic behind the "waiting for worst to happen" strategy? Or do we still naively believe in some sort of miracle that will remove all environmental issues in the blick of an eye?

The time for action is running out, and yet so many people remain ignorant about it. Many people care very little or none at all about what will our planet look like in 50 or 100 years from now.

We must ask ourselves what will happen to our children and grandchildren if we remain ignorant about our environment. Their destiny lies in our own hands.

Ecological crisis - Earth is still our only home

There is no doubt that current condition of our planet definitely belongs under "global ecological crisis" category. We made tremendous environmental mess over the years, and as always things need to become critical before we start fixing them. Mother Earth is down on her knees not able to defend herself from so many different ecological problems. By helping our planet we are helping ourselves because Earth is still our only home.

We seem to be constantly forgetting how Earth existed many years before us, and how Earth can exist without us. We, on the other hand cannot exist without Earth because Earth is so far the only planet capable to support life. We should stop taking things for granted, and accept the fact that we are not supreme rulers of our planet. Ecology, environment, and general health of our planet have been on sidelines all the time, not able to compete with the greed for an almighty dollar as the ultimate goal of our civilization. People are greedy, they think only of material goods, and almighty dollar is always ahead of everything else.

Just take a look at how world leaders instantly jumped to solve financial crisis and global recession. Billions and billions of dollar given in such a short time to save financial markets, if only small percentage of this money was used for environmental issues we wouldn't be now talking about global ecological crisis. On the other hand international climate deal, a must thing to avoid ultimate environmental disaster in years to come is still in question, still depending on politics to decide whether this is top priority or not.

Can you imagine this? With so many different ecological problems politicians are still discussing whether environmental issues like climate change are top priorities or not, and whether we still have time to postpone work on their solutions. Time may sound endless from general point of view but global ecological crisis should have given us by now the real proof that time is one luxury we do not have at our disposal. Global ecological crisis will soon turn into global ecological disaster if we continue with our ignorance towards reality we live in. Since we became dominant species on this planet we have done so many bad things. It would really be nice to do something good for a change. Wouldn't it?
