Look at the picture and guess what problems are described in the pictures.

Then answer the question: What do you know about these problem?

Read the text and select the statement that expresses its main idea.

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.
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. 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.
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 temperatures can reduce crop harvests globally, which may lead to famine. 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 a matter of great concern for humans since we cannot exist without species diversity on Earth.
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.
