北師大版高中英語(yǔ)模塊7--Unit 22 lesson3-3 [00:00.98]C So why is nature beginning to turn on us? [00:05.71]One answer is over-population. [00:07.86]The population of the world [00:09.12]is growing at the rate of 10,000 people [00:11.54]an hour,240,000 every day, [00:15.91]nearly 90 million a year, [00:18.52]with most of the growth in the developing world [00:21.31]People in agricultural areas, [00:23.69]unemployed and sometimes undernourished, [00:26.47]move to the cities,and then set up unstable, [00:29.69]sub-standard homes on poor soil [00:32.03]which can easily collapse in earthquakes [00:34.35]or slide downhill in landsides. [00:37.36]On top of that,add climate change [00:39.99]and the spectre of globle warming. [00:42.42]This has mainly been caused [00:43.65]by the mismanagement of the world's resources: [00:46.66]carbon emissions from rich countries; [00:48.90]the activities of the [00:49.83]big multi-national companies; [00:52.45]the deforestation for the world's forests. [00:55.30]As a result,a hotter ocean leads to fiercer [00:58.34]typhoons and hurricanes. [01:00.23]Greater quantities of water evaporate, [01:02.52]and more powerful winds dump this water [01:05.36]against mountainsides with increasing strength. [01:08.47]Atlantic hurricanes, [01:09.82]for instance, are 40% stronger now [01:13.11]than they were 30 years ago. [01:14.29]
