Learning objectives
In many ways, life has become far more comfortable and convenient in the past few decades. However, this has come at a huge cost to the environment. Here, we look at three of the most serious environmental problems we are currently facing.
Lead-in
Air Pollution
Global Warming
Overflowing Landfills
Discuss the environmental problems and make notes on these three points:
Cause – Effect - Solution
Air Pollution
The main cause of air pollution is the burning of fossil fuels1 by vehicles and power plants. Other human activities，such as construction and the burning of waste，also contribute to air pollution.

The effects on our health can be very serious. According to the World Health Organisation， 2.4 million people die annually from causes directly related to air pollution. Young children，the elderly and people with heart and lung problems suffer the most as a result of this environmental problem.

You can easily contribute to reducing air pollution by only using a car to make journeys when it′s absolutely necessary. If it isn′t, try using public transport instead.

Global Warming
Global warming is the increase in the
temperature of the Earth′s near-surface air
and oceans. It′s caused by the build-up of carbon dioxide2 and other pollutants3 in the atmosphere. These trap the Sun′s heat and warm up the planet.

Over the past 100 years，average temperatures around the world have risen by between 0.5 ℃ and 1 ℃ . Scientists predict that temperatures will rise by a further 1℃ to 3.5 ℃ during the 21st century.

Global warming has already caused a wide range of problems. Sea levels are rising due to the melting of polar ice sheets. Countries around the world have faced extreme weather conditions，such as hurricanes，floods and heat waves.

For example，the south of France and northern Italy experienced extremely heavy rain and 1,000km/h winds in November 2016. Over 200mm of rain fell in just one night. This resulted in the flooding of the River Po near Turin in Italy.

Overflowing Landfills
Landfills are used for waste disposal
in many countries around the world .
However，due to the amount of waste our lifestyles produce，these landfills are now reaching full capacity4. When this happens，the chances of dangerous chemicals in the waste entering our water supply increase.

The amount of waste in landfills in China has risen exponentially5 over the last decade. In 2005，for instance，landfills in Shanghai contained a little over 6.2 million tonnes of waste，but they now contain 7.9 million tonnes － an increase of nearly 30%.

In Hong Kong，it is predicted that the three existing landfills will be full within the next decade. The government is now trying to find alternative waste disposal methods. Some cities， such as Beijing and Shanghai， among others，are leading the way and have promised to send “zero waste to landfill”by 2025.

Apart from the three Rs (Reduce, Reuse and Recycle), some experts have begun advocating the fourth R - Responsibility They believe that, although recycling waste is effective，the most effective way of solving the problem of overflowing landfills is to encourage people to take responsibility for reducing the waste they produce themselves.
While-reading
Read the texts. Answer the questions.
1 What are the causes and effects of air pollution
2 What is global warming and how does it affect our planet
3 What are landfills and why are they becoming a serious problem
4 What are the possible solutions to these environmental problems
While-reading
1 What are the causes and effects of air pollution
The causes of air pollution are： the burning of fossil fuels，construction，the burning of waste.
The effects of air pollution：are serious health problems and deaths.
While-reading
2 What is global warming and how does it affect our planet
Global warming is the increase in the temperature of the Earth′s near-surface air and oceans. It affects our planet in many ways： sea levels are rising due to the melting of polar ice sheets and countries around the world have faced extreme weather conditions， such as hurricanes，floods and heatwaves.
While-reading
3 What are landfills and why are they becoming a serious problem
Landfills are big spaces of land used for waste disposal. They are becoming a serious problem because landfills are now reaching capacity and therefore the amount of chemicals in the waste entering our water supply increased.
While-reading
4 What are the possible solutions to these environmental problems
Some possible solutions to these environmental problems，are：using public transport instead of driving，recycling your waste and reducing the amount of waste you produce.
While-reading
What do you think of the fourth R- Responsibility Do you think it’s more important than the other three Rs (Reduce, Reuse and Recycle) Why
Write a 120-word passage about how to protect the environment.
