环境发展:保持稳定还是变革?
About this debate
Sustainability implies stability. Development implies change. How can the two be reconciled? And what is the role of chemistry in that reconciliation? In a debate linked to the Annual Nobel Laureate Meeting in Lindau, Germany, which this year gathers winners of the chemistry prize, we investigate this question.
Chemistry has an important role in bringing about any reconciliation. It can produce substitutes for things that now require expensive and polluting mineral extraction. It can clean up effluent, including carbon dioxide, that would otherwise contribute to climate change. And it can help with the efficient capture of sunlight to make electricity and non-fossil fuels. But will that be enough? Or is "sustainable development" truly the oxymoron that it sounds?

The proposer's opening remarks

Sustainable development is a beautiful-sounding idea that has become intellectually bankrupt完全失败 and should be abandoned.(定主题基调) It leads to wrongheaded thinking about the real causes of economic and environmental troubles. And it encourages governments to adopt terrible policies.(负面影响)
The original thinking behind sustainable development was smart and proper.(让步) Back in 1987 the Norwegian prime minister, Gro Brundtland, chaired a commission on economics and greenery绿色环保 that famously called sustainable the kind of development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."
In the decades since, the concept of sustainable development has grown more popular because its meaning has become fuzzier. The problems have arisen on four fronts.(现在出现了如下问题)
First, advocates for sustainable development have used the concept's ambiguity as a licence to embrace引起 stasis and autonomy. There is no question that we face severe environmental challenges because we are using some resources at a rate faster than they can regenerate. But that is hardly new: human society, especially in the industrial eras工业时代, has always leaned hard on its resources. And we have fixed most of those problems through radical彻底 changes in technology and behaviour.(泛泛谈一下) Three hundred years ago analysts were terrified about a scarcity不足 of salt needed to cure foods, and reminiscent of使人想起 today's oil security woes不幸灾难, governments created national champion companies to make their nations independent in salt. But as Mark Kurlansky's history, Salt, has shown, society fixed the salt problem mainly through innovation: canning and refrigeration, in particular. And the societies that did best in managing their salt troubles were those most open to change and international trade in ideas and technologies.(具体事例剖析)
Nothing in the original idea of sustainable development mandated要求 independence and stasis.(Nothing引起...) But as the deep greens have taken hold of影响 the idea they have pushed it this direction向...方向推进. In reality, well-focused technological change is a saviour, not an evil that undermines sustainable development.(比喻!!!) Today's challenges, such as global warming, are no different. Global warming is so huge a challenge that it seems unsolvable. But it can and will be solved the same way that society shook its dependence on salt: through new technologies and shifting to new resources.
The second trouble with sustainable development has arisen with future generations. Indeed(让步), it was this aspect of Brundtland's report—a focus on stewardship管理 for future generations—that garnered the most attention得到关注. Yet on this front woolly混乱的乱糟糟的 thinking has also destroyed the original idea. Concern about对于...的担心 future generations has become a one-sided game that focuses only on harms.(表达只带来危害的好句!!!) In reality, the damage of extracting resources also produces huge benefits such as new ideas and investment in infrastructure基础设施 that also pass to future generations. It has proved hard to measure and value all the goods and bads, but the assets that most generations pass to their descendants usually far exceed the liabilities超过应该负的责任(很难判断好坏,AW!!).
The third front is policy. The original concept of sustainable development encouraged policies that used resources so long as the depletion was efficient and focused on long-term investment.(先引申一段) On that basis, societies extracted salt from the earth, depleted消耗 minerals and engaged in a host of许多 seemingly unsustainable activities. Yet they were exactly the right thing to do because they promoted economic growth that, with smart regulation, shifted our societies to other resources. Yet today the deep green advocates for sustainable development seek energy independence and autonomy. (注意两个YET)They are terrified of恐惧 treading on践踏 any resource and thus undermine the human ingenuity创造力换词 that is essential for us to sustain our place on the planet地球换词.
Today, ground zero in the sustainable development debate is so-called renewable power可再生能力. Many governments are spending a fortune on the logic that if it is renewable it must be sustainable. Yet the reality is totally different. Many renewable sources may recharge their energy resources, yet they have other heavy footprints on our resources. Wind turbines风力发电, for example, are an eyesore眼中钉 on open spaces and wilderness. Like the oil pipelines of yesteryear去年, they need access roads that open landscapes to abuse, and all the power lines that carry renewable wind to markets are an extra pressure on the land. And this problem is hardly unique for wind.(过渡句,不仅是...) Disastrous renewable biofuels生物燃料 policies, wrapped in the deep green of sustainable development and energy independence, have caused a horror on the landscape and, some say, threaten food supplies.
For policy, what matters most is getting the accounting and the regulatory signals right.(提出问题所在) Global warming persists because barely仅仅 any government has really tackled应对 that challenge, not because societies are underspending on花费少 favoured renewable energy technologies or other darlings好处 of the deep green. Just because fossil fuels are finite does not mean that they should not be used, if married with密切联系 clear and strong incentives刺激 to be frugal and to lighten their environmental footprint减少影响.
Finally, sustainable development has become about greenery. But in Brundtland's sage definition it was about many other dimensions维度: protection of human rights, dignity and fairness权利尊重公正. Those ideas, vague all, remain essential today. Indeed, the developing world is rightly afraid that all the greenery in the North will be an excuse借口 to ignore these many other aspects of welfare that, in the end, are what civilisation is all about.
Back in 1987 sustainable development was a smart and attractive idea because nobody really knew what it meant. As I outlined in more detail in the magazine Foreign Affairs ("Recovering Sustainable Development", January 2006), the last two decades have yielded an empty debate空洞辩论. Intellectually and politically, sustainable development is not sustainable and has become dangerous. It should be abandoned.

The opposition's opening remarks
Dr Peter Courtland Agre M.D.
University Professor and Director, Johns Hopkins Malaria Research Institute
With apologies to English teachers everywhere, my position to this statement is the double negative—"sustainability is not unsustainable."(委婉的写法,可能要提及english teacher) But this may be true only if we in America get a firm national grip on reality紧紧抓住问题. I focus my argument on America as it is the world's biggest economy and (with China) its worst polluter.(旗帜鲜明的指向)
Our situation is indeed exceedingly极其 grim—increasing release of toxins into the environment, energy gluttony and the appearance of epidemic obesity(环境问题非常好的举例!!!环境污染资源浪费瘟疫横行). Compounding these problems is the nearly total lack of thrift among Americans whose uncontrollable consumerism用户至上 is sufficient to support multiple shopping channels on the television 24 x 7 x 365 at a time of unprecedented debt.(指出原因)
To have the world's biggest economy is irrelevant if we squander our wealth on fluff浪费钱财在无价值的东西上. Popular television advertising revenues alone could sustain significant educational reform in the US. Consider for example that one second of advertising during the Super Bowl retails for零售 $100,000—twice the annual salary of a beginning schoolteacher. The wisdom behind the rising economy in China must be questioned, since they now have 3% of the world's paved roadways铺设道路 but 21% of the world's highway fatalities致命的. If this truly reflects giving the public what it wants, we are most certainly doomed.(学习super bowl 和 paved roadways例子)
Rather than arguing that science will save us simply through new inventions, let me suggest that it is wisdom from our history that may save us.
Altering behaviour is exceedingly difficult but not impossible.Before the arrival of the Europeans, North America was home to the Native American Indians. Their culture had remarkable beauty but was technologically primitive. Native Americans lacked the wheel, had no units to measure time shorter than one day, and often faced starvation in winter. But in terms of wisdom, they had remarkable ability. Important tribal decisions were only made after the elders considered consequences their decisions would have seven generations in the future.The concept of "Seven Generation Sustainability" was known to our Founding Fathers. If we consider the mindset of America's leaders seven generations back, it would include wisdom not commonly articulated by提出 many of our leaders today. Moreover, is it possible that the Founding Fathers' wisdom is still current? Let us revisit some pearls dropped by two of our Founding Fathers who also happen to have been scientists—Benjamin Franklinand Thomas Jefferson.(学习前辈的宝贵经验,承上启下)
Franklin said, "A penny saved is a penny earned" and "Poor man, said I, you pay too much for your whistle." Would our current Federal Reserve联邦储备银行 Chairman question Franklin's thoughts on thrift? "Never spend your money before you have earned it": excellent advice from Jefferson, but a trait that he did not adhere to personally. While Franklin was not well known for his positions on natural conservation, his wit was poignant: "When the well's dry, we know the worth of water." Jefferson was more outspoken直率 on issues of the natural world. "There is not a sprig of grass that shoots uninteresting to me."
Wisdom and political mobilisation动员鼓动 of the sort achieved by the Founding Fathers are needed today to bring about sustainable development. Given proper investment, scientific development of renewable and environmentally friendly sources of energy is likely合适. Design of modern, livable cities with expedient forms得当措施 of public transportation is feasible可行. But the determining factor决定因素 is likely to be our national will. Are we willing to do the necessary belt-tightening紧密联系? Do we want this enough to make the sacrifices necessary?(让步+质疑)
Achievement of sustainability can only occur if the public demands it. My view is that a populist平民 revolt for反对 sustainability must be initiated, and it must include the young. Jefferson claimed that "Every generation needs a new revolution," and Franklin that "Many people die at 25 but are not buried until they are 75." Our younger generation will determine if the right decisions are undertaken by becoming engaged in the most important issue of our time.
Specifically确切的说, we must place greater emphasis on what can be done currently and less on wishful thinking about miracle inventions that are allegedly依其引述 imminent. Ranks of the progressives are consumed with internecine内讧/两败 conflict about use of coal, our most plentiful energy source, for the generation of electricity. Let us not delay the opportunity让我们抓住机会, both in the US and in China, to convert from traditional coal-burning technology to modern integrated coal-gasification power with dramatic reductions in greenhouse gases because perfection has not yet been achieved从没有完成.
We Nobel laureates桂冠 are often congratulated on being brilliant and important (in truth we like it), but this needs to be reconsidered from a different perspective.从另一个角度看问题 As President Kennedystated at the White House dinner for 49 Nobel laureates in May 1962, "I think this is the most extraordinary collection of talent, of human knowledge, that has ever been gathered together at the White House, with the possible exception of when Thomas Jefferson dined alone."
This underscores强调 Jefferson's view that "One man with courage is a majority."(quote:个人和社会关系的论题) A call for national activism行动派 is necessary. If Franklin and Jefferson were here today, I suspect that they would tell us that the future of society and the future of the planet seven generations from now will most certainly reflect the decisions made by today's leaders and the actions of our younger generation.
While Barack Obama may not be a modern-day当代换词 Thomas Jefferson, he demonstrated remarkable wisdom by appointing Nobel laureate Steven Chu as secretary of energy. Chu is a hero to many young scientists and environmentalists in the United States, and as a first-generation Chinese-American, he is celebrated widely in China. At last we may have national leadership that can pull us up to our full stature会得到较好发展. I choose to be optimistic.
