3h Curricular: Geography
1 Read the title and subheadings in the text. Can you answer any of these questions? Listen to and read the text and check.
What is deforestation?
Deforestation occurs when people cut down whole forests of trees. Tropical rainforests are particularly under threat. Two thirds of the lowland tropical rainforests in Central America, for instance, have been turned into land for grazing since 1950.
Why is it happening?
Small farmers cut down a few acres of trees in order to grow crops or let their animals graze. They clear them in a process called “slash and burn”. Loggers also cut down a lot of trees for wood and paper products and urban developers turn areas of forest into mines, new roads, homes, or factories. Natural factors such as wildfires sometimes contribute to deforestation, too.
Why is it such a problem?
Deforestation is a major threat to the delicate ecosystem of our planet. Basically, it destroys the homes of animal and plant species and many of them die out including many unique species that could be used to make medicines for some of the world’s worst diseases. More than two thirds of all medicines with cancer-fighting properties, for example, come from rainforest plants. Also, trees absorb harmful greenhouse gases. When forests are cut down or burnt, most of these gases stay in the Earth’s atmosphere, which speeds up global warming. In fact, in the next 24 hours, deforestation will be responsible for the release of as much CO2 into the atmosphere as that from as many flights as it takes to carry 8 million people from London to New York!
How can we help to fight deforestation?
Take part in tree-planting days to replace some of the lost trees.
Recycle paper and buy recycled paper products such as notepads.
Eat less meat or at least check where it has come from. If it’s from rainforest areas, it’s likely that rainforests were cut down in order to raise cattle.
Encourage your family, friends, and neighbours to think about the rainforests too by telling them all about the issue and how they can help.
Support charities and companies that support rainforest protection by donating money and buying wood products like furniture made from sustainable forests.
RAINFORESTS: FAST FACTS
Tropical rainforests cover 6-7% of the Earthtasks surface. The largest are: 1) The Amazon, South America; 2) The Congo, Africa, 3) South East Asia, 4) New Guinea, 5) Madagascar.
Areas of forest the size of 2 football fields are lost per second due to deforestation. If this rate continues, the worldtasks rainforests will disappear within 100 years.
Rainforests are home to over half the plant and animal species in the world, 137 species become extinct every day.
2 Read again and complete the sentences in your notebook.
1 In 100 years, there might not be any tropical rainforests left.
2 Farmers burn down forests because they want to grow crops or let animals graze.
3 Many plants useful for making medicines are only found in rainforests.
4 Greenhouse gases increase if forests are cut down or burned.
5 We should try not to eat meat that comes from rainforest areas.

4 Think! Imagine plants and trees could talk. What could they tell us about deforestation? In three minutes, write a few sentences. Tell your partner or the class.
5 ICT Find out more information about deforestation. Use the key word: deforestation. Tell the class.
