Throughout the past century humanity did everything in its power to control nature. We dammed earth’s rivers, chopped down the forests and exhausted the soils. Burning up fuels, we pumped a great deal of greenhouse gases into the air, altering the chemistry of the atmosphere and warming the planet in just a few decades. And as our population began in the year 2000 above the 6 billion mark, still spreading across the continents, dozens of animal and plant species were dying out every day, including the first primate(灵长类)to disappear in more than 100 years.
As the start of the 21st century there were unmistakable signs that nature was beginning to take its revenge. Melting ice in both poles of the earth suggested that the climate was changing rapidly. Weather was even more changeable than usual, giving some places too little rain and others too much. Fires raced across the dried American West last summer, and recent storms spread damages from Britain to China. No specific event could be directly blamed on global warming. Floods and drought will be more frequent and severe. Other sad signs from an overburdened planet include falling grain and fish harvests and fierce competition for scarce water supplies.
But there were also, in the year 2000, signs of great awareness. Connected by the Internet, hundreds of millions of people gathered for the 30th anniversary of Earth Day. Governments from Washington to Lima took steps to protect the large wild areas from development. Progress was made toward using more renewable energy from the wind and the sun, and new cars that used both gasoline and electricity spotted(显示)fuel-economy statistics.
The goal for the new century is "sustainable development" . Is that possible? It depends on how well we understand that humanity is part of nature, not lord and master.
It can be inferred from the passage that scarce water supplies are directly caused by( ).
选项
A、less ice in both poles
B、the more changeable weather
C、something not mentioned in the text
D、the larger population
答案
D
解析
推理判断题。由文章第二段“Other sad signs from an overburdened planet include falling…for scarcewater supplies.”可知,是由于地球不堪重负才导致水资源不足,而地球不堪重负肯定是人口过多导致的。故选D。
