Our endangered world

You probably already know a lot of words for talking about the environment, pollution, and so on. In this unit we focus particularly on collocations (words that are oft en used together). Try to learn these and use them in your writing.

A	Threats and potential threats to the environment Shrinking habitats1 are a threat to biodiversity2, in terms of both plants and animals, and endangered species3 need legal protection if they are to survive. Although some climate change sceptics4 disagree, most scientists believe that global warming5 will increase. This will encourage polar ice to melt, resulting in rising sea levels and climatic changes. Carbon (dioxide) emissions6 from the burning of fossil fuels7 are contributing to the greenhouse effect8. In addition, population growth exerts severe pressure on9 finite resources10, and the ecological balance11 may be upset by uncontrolled deforestation12. Demographic projections13 suggest the world population will continue to grow exponentially14, putting extra pressure on depleting resources15. Waste disposal16 is an increasing problem and toxic waste17 is contaminating18 many rivers and seas. Safe water may become an increasingly precious commodity19, leading to issues of water security20. One of the worst-case scenarios21 is that there will be no tropical rainforests left by the year 2050. Our only hope is that pristine environments22 such as Antarctica can be protected from development and damage, so that at least these habitats are preserved. 1 places where animals live and breed which are decreasing in size 2 variety of different types of biological species 3 types of animals/plants which are in danger of no longer existing 4 people who do not believe that climate change is a serious issue 5 steady rise in average world temperatures 6 carbon dioxide gas from factories, cars, etc. 7 coal, oil, etc. 8 warming of the Earth’s surface caused by pollution, where gases trap and redirect heat back down to the Earth’s surface 9 puts great pressure on; formal 10 limited resources that will eventually run out / be exhausted 11 balance of natural relationships in the environment 12 unrestricted destruction/clearing of forests 13 forecasts about the population 14 grow extremely rapidly 15 resources that are reducing 16 getting rid of waste 17 poisonous waste materials 18 poisoning (something) 19 very valuable substance 20 ability to ensure that a population has safe drinking water 21 the worst possibilities for the future 22 perfectly clean/untouched/unspoilt areas
B	Responses to environmental issues and problems Look at these newspaper headlines and note the useful phrases. 1 reputation for positive support of the environment and for making policies that reflect this 2 people who always make the most depressing or pessimistic predictions about the future 3 development of industry, etc. which does not damage the environment or social and economic stability, and which can continue over a period of time 4 energy produced using sun, wind or crops rather than coal or other fuels which cannot be replaced once used
	Common mistakes People cause damage to the environment (NOT damages).

EXERCISES

33.1	Make these sentences formal by using words and phrases from A opposite instead of the underlined words, making any other necessary changes. 1 All that carbon-what’s-it-called gas put out by cars and factories is a major problem. 2 These flowers here are a type there’s not many left of, so it’s illegal to pick them. 3 A lot of wild animals have to survive in smaller and smaller areas where they can live. 4 A lot of Patagonia is a completely spotless area that’s never been touched. 5 We have to look after the things we use on this planet because they won’t last for ever. 6 If the cutting down of trees continues, there will be no forest left ten years from now. 7 Burning coal and oil and stuff like that causes a lot of pollution. 8 The sea will get higher if this heating up of the world continues. 9 Increasing population puts really big pressure on economic resources. 10 The way things all balance one another in nature is very delicate.
33.2	Complete the following table, using a dictionary if necessary. Do not fill the shaded boxes. noun verb adjective adverb climate demography project sustain contaminate toxic deplete
33.3	Correct the mistakes in this paragraph. Profits of boom and gloom are always saying that we are heading for an environmental catastrophe, and that unless we adopt a policy of attainable development, we will cause irreparable damages to the planet. The worst-place scenery is of a world choked by overpopulation, the greenhouse affect and traffic gridlock. Much of what is claimed is exaggerated, but politicians are influenced by such voices and are always trying to improve their green potentials in the eyes of the voters.
33.4	Match words on the left with words on the right to make collocations about the environment. 1 renewable a scenario 2 demographic b sceptic 3 precious c effect 4 polar d energy 5 waste e projections 6 greenhouse f disposal 7 worst-case g commodity 8 climate change h ice
