Green Issues
1 What do you know about deserts? What else would you like to learn? Think of three questions. Read the text and see if you can answer them.
Deserts
Deserts cover approximately 0) one quarter of the earth’s land surface and are home 1) to more than 500 million people in the world. They are also among the world’s most important eco-systems and are filled with thousands of rare and useful animal and plant species.
As many of the world’s fragile environments are suffering because of climate change, it’s 2) not surprising that deserts are under threat too. In Iran’s Dasht-e Kavir Desert, for example, rainfall has 3) been dropping by 16% per decade. Reduced moisture and higher temperatures in areas that are already very dry means that animals struggle to survive, crops fail, water reserves dry up and as a 4) result life becomes generally more difficult for the people who live there.
5) What is perhaps more surprising, is that deserts are also expanding at an alarming rate! As populations 6) get bigger, especially in the areas of fragile land at the edges of deserts, fields are over-farmed and lose their nutrients and more trees are cut 7) down for firewood or to make space fa development. This causes the soil to erode and become unusable, slowly but surely turning to desert. Damaging dust storms can also blow away soil and cause bone dry sand dunes to ‘spread’ onto previously usable land.
In the 8) past fifty years alone, the Sahara desert has spread by 65 million hectares. And non-desert areas are 9) at risk, too. 31% of Spain, for example, is under threat of desertification. In fact, entire parts of the world could become uninhabitable, facing people to flee to already crowded greener countries.
So, what can be 10) done about this worrying situation? Well, unfortunately desertification к irreversible but we can all continue to help stop global warming simply 11) by using less energy. Or why not donate money to a project that plants trees to stop erosion in desert areas, or even 12) take part yourself?
