材料一：工业革命的重要内容之一就是对农业的改造，也就是以农业为主的经济转移到工业经济上来。诚然，在英国工业革命已经开始的年代里，土地仍然是英国人的主要资源和财富，然而农业人口的变化早在15世纪开始就悄悄地进行着。。。。

——《欧洲文明扩张史》

材料二：英国诺丁汉大学教授郑永年指出：所谓的一个国家外部的崛起，实际上是它内部力量的一个外延。在国家内部的制度还没有健全的情况下，很难称为一个大国，即使称为大国，也不是可持续的……环顾当时的世界，法国正在君主专制的鼎盛时期……大清王朝268年的江山才刚刚坐了44年。但是英国，这个地方边缘的小国，却在历史性的转变中抢占了先机，已经率先到达现代文明的入口处，即将一步步稳健地走向世界的中心。在下两个世纪里，它将傲视全球。

材料三：16～19世纪英国城市人口占总人口比例(%)

材料四：英国是蒸汽机的故乡。……可是煤烟带给英国的灾难是将房屋、树木、雕塑、桥梁一切都熏成黑色，就连泰晤士河也不例外。……伦敦的烟雾中毒事件也是全世界纪录之先……

——徐刚《世纪末的忧思》

材料五：1848年英国颁布了《公共卫生法》，1878年通过了《公共卫生条例》，至此英国基本上建立起了完整的水资源污染防治的法律体系。工人阶级提出了改善自己生活条件的要求，……也包括着，改善公共卫生条件，消除环境污染等内容……。英国公共卫生体系的创立者查德威克，……用大量事实说明了环境污染造成的疾病流行，并提出了一系列对策。他们锲而不舍的努力，换来了环境的改善，使人们重新获得享有良好环境的权利。

    Lindsay Renwick, the mayor of Deniliquin, a country town in New South Wales, misses the constant whir（嗡嗡声）of the rice mill whose giant fans dried the rice. The Deniliquin mill, the largest rice mill in the Southern Hemisphere (南半球), once processed enough grain to meet the needs of 20 million people globally. But six years of drought have had a destructive effect, reducing Australia's rice crop by 98 percent and leading to the mothballing of the mill last December.

    Drought affects every agriculture industry based in Australia, not just rice – from sheep farming, the country's other backbone, to the cultivation of grapes for wine, the fastest-growing crop there, with that expansion often coming at the expense of rice. The drought's effect on rice has produced the greatest impact on the rest of the world, so far. It is one factor contributing to skyrocketing prices, and many scientists believe it is among the earliest signs that a warming planet is starting to affect food production.

    Researchers are looking for solutions to global rice shortages – for example, rice that blooms earlier in the day, when it is cooler, to fight against global warming. Rice plants that happen to bloom on hot days are less likely to produce grains of rice, a difficulty that is already starting to emerge in inland areas of China and other Asian countries as temperatures begin to climb. 'there will be problems very soon unless we have new varieties of rice in place,” said Reiner Wassmann, climate change director at the International Rice Research Institute (IRRI). The recent reports on climate change carried a warning that could make the news even worse: that existing models for the effects of climate change on agriculture did not yet include newer findings that global warming could reduce rainfall and make it more variable.

    Yet the effects of climate change are not uniformly bad for rice. Rising concentrations (浓度) of carbon dioxide, the main greenhouse gas, can actually help rice – although the effect reduces or disappears if the plants face unnecessary heat, inadequate water, severe pollution or other stresses. Still, the flexibility of farmers here has persuaded some climate experts that, particularly in developed countries, the effects of climate change may be relieved, if not completely avoided. “I'm not as negative as most people,” said Will Steffen, director of the Fenner School of Environment and Society at Australian National University. “Farmers are learning how to do things differently.”

    Meanwhile, changes like the use of water to grow wine grapes instead of rice carry their own costs, as the developing world is discovering. “Rice is an essential food,” said Graeme Haley, the general manager of the town of Deniliquin. “Wine is not.”
