Speaking at the Sustainable Development conference in London, Britain’s chief scientific advisor warns that under the backdrop of a growing global population, the world will face a “perfect storm” of threats as food, water and energy shortages combine to impact society by the year 2030. Dr. John Beddington says in just more than 20 years, the world’s population will reach 8.3 billion. In and of itself, that means needs will be greater in the future. As this happens, Britain’s chief scientific advisor warns that resources will be under increased pressure and climate change will also come into play, exacerbating problems. “There is an increase in the demand for food. That is going to be up by about 50 percent by 2030,” Dr. Beddington said. “The increase in demand for energy is going to be up by a similar amount and the demand for fresh water, which is really very important, is going to be up by something like 30 or 40 percent.”
Professor Beddington says now that oil prices have dropped again, domestic and international pressure to deal with energy issues that we will have to confront in the future may well decline. But he underlines it is absolutely necessary to develop green solutions to lessen the impact that climate change will inevitably bring. The U.N. Environment Program predicts the amount of fresh water available will drop off sharply in parts of Africa, Asia and Europe by the year 2025. If little is done in the coming years, Beddington says the “perfect storm” of threats will increase the likelihood of unrest, conflict and mass migration in various parts of the world.
Questions 29 to 31 are based on the passage you have just heard.
29. What is the passage mainly about?
30. What will the world’s population be in about 20 years, according to Dr. John Beddington?
31. Why does Professor Beddington suggest developing green solutions?
选项
A、The world’s population in 2030.
B、The resources crisis by 2030.
C、The worsening of environment by 2030.
D、Several measures to protect the earth.
答案
B
解析
选项均为名词性短语且概括性强表明,本题可能考查短文主题。短文开头提到,英国的首席科学顾问指出,在世界人口增长的大背景下,世界将会面临来自食品、水源和能源危机综合影响下的全面威胁,接下来文章便围绕这几项资源危机而展开,由此可知,短文主要讲述了将在2030年到来的资源危机,故答案为[B]。
