UNIT 6: GLOBAL WARMING






A. Global warming is the rise in the world`s temperature.
B. Global warming leads to the extinction of millions of species in the world.
C. Global warming is mainly caused by humans and has negative impacts on people`s lives.
D. People have to work together to reduce the risks of global warming.
1. Which statement expresses the main idea of the text?
READING
Global warming, the rise in temperature around the earth`s atmosphere, is one of the biggest issues facing humans nowadays. The results of numerous studies show that global warming is real. It is mainly man - made and its effects on people and nature are catastrophic.
READING
The biggest cause of global warming is carbon dioxide (CO2) emissions from coal burning power plants. When coal is burnt to make electricity, it releases a large amount of carbon dioxide into the atmosphere. In the USA, about 40% of CO2 emissions come from electricity production. The second greatest source of CO2 emissions is the burning of petrol for transport. In the USA, motor vehicles running on petrol are responsible for about 33% of CO2 emissions.
READING
 The situation is getting worse as the demand for cars is increasing rapidly in the modern world. Another reason for the temperature rise is the cutting down of forests for wood, paper or farming. Forests absorb and capture CO2 from the atmosphere. This process has been disrupted by the current alarming rate of deforestation.
READING
The worst effect of global warming is the rise in sea levels worldwide, which could make millions of people lose their homes. Global warming also results in severe weather - related natural disasters such as droughts and floods that can kill or injure large numbers of people. Global warming with increasingly high temperature can reduce crop harvests globally, which may lead to famine.
READING
It is also predicted to have the worst impact on water supplies. Water shortages are likely to delay economic growth and damage ecosystems. Another scary effect of global warming is the disappearance of millions of species in the world. Widespread loss of species is matter of great concern for humans since we cannot exist without species diversity on Earth.
READING
It is important that people understand that human - caused global warming is happening and its effects on us are serious. Everybody has to take some action now to reduce the risks.

ANSWER THE QUESTIONS
1. Who is mainly responsible for global warming?
Humans are responsible./People are responsible./We are responsible.
2. What happens when coal is burnt to make electricity?
It releases a large amount of carbon dioxide into the atmosphere.
The biggest cause of global warming is carbon dioxide (CO2) emissions from coal burning power plants. When coal is burnt to make electricity, it releases a large amount of carbon dioxide into the atmosphere.
3. How does deforestation contribute to global warming?
Another reason for the temperature rise is the cutting down of forests for wood, paper or farming. Forests absorb and capture CO2 from the atmosphere. This process has been disrupted by the current alarming rate of deforestation.
Deforestation disrupts the process of absorbing and capturing CO2 from the atmosphere, which causes the world’s temperature to rise.
4. What could happen to people when sea levels rise?
The worst effect of global warming is the rise in sea levels worldwide, which could make millions of people lose their homes.
 They could lose their homes.
5. How can high temperature affect crops?
Global warming with increasingly high temperature can reduce crop harvests globally, which may lead to famine. 
They can reduce crop harvests globally.
6. Why is widespread loss of species a matter of great concern for humans?
Widespread loss of species is matter of great concern for humans since we cannot exist without species diversity on Earth.
Because humans cannot exist without species diversity on Earth.
WHAT SHOULD WE DO TO REDUCE THE RISKS CAUSED BY GLOBAL WARMING ?
Reusing and recycling glass, plastic, paper and other products.
Reducing use of paper products.
Travelling by air around the world to study global warming.
Cutting down on energy use: use LED light bulbs and unplug unused electronic devices.
Using green methods of transport: ride a bicycle or just walk.
Planting trees or plants wherever they can grow.
Living in forests surrounded by a diverse population of species.
