📚 Environmental and Ethical Issues | 环境与伦理问题
Environmental science tells us what is happening to the planet, but it does not tell us what we ought to do. This is where environmental ethics becomes important. Ethics is the branch of philosophy that studies right and wrong, justice and responsibility. When applied to the environment, it asks how we should treat nature and how our choices affect other people and living things.
环境科学告诉我们地球正在发生什么，但它并不告诉我们“应该怎么做”。这正是环境伦理的重要性所在。伦理学是研究对错、公正与责任的哲学分支；当它应用于环境时，便会提出我们应如何对待自然，以及我们的选择如何影响他人和生物。
For example, cutting down a rainforest can be described in terms of timber profits, but an ethical approach also asks what is lost: species, indigenous livelihoods, carbon storage and the rights of future generations. Environmental decisions are therefore both scientific and ethical at the same time.
例如，砍伐一片雨林可以从木材利润的角度来描述，但伦理视角还要求我们追问：我们失去了什么？物种、原住民生计、碳储存功能以及未来世代的权利都包括在内。因此，环境决策同时既是科学问题，也是伦理问题。
1. Ethical Perspectives on Nature | 自然观的主要伦理视角
People hold different ethical beliefs about nature. These beliefs often influence how governments, companies and individuals manage the environment. A useful way to summarise them is through three perspectives: anthropocentrism, biocentrism and ecocentrism.
人们对于自然有着不同的伦理观念。这些观念常常影响政府、企业和个人如何管理环境。一个有用的归纳方式是通过三种视角：人类中心主义、生物中心主义和生态中心主义。
Anthropocentrism places human interests at the centre. Nature is valuable mainly because it provides food, water, timber, medicine, recreation and other benefits to people. In this view, a forest should be protected if it is useful to humans, such as by preventing floods or absorbing carbon dioxide.
人类中心主义将人类利益置于中心。自然是因其为人类提供食物、水、木材、药物、休憩和其他利益而有价值的。在这种观点下，森林之所以应被保护，是因为它对人类有用，例如防洪或吸收二氧化碳。
Biocentrism holds that all living organisms have value in their own right. It argues that every species has a good of its own and deserves moral consideration, regardless of its usefulness to people. A turtle or a tree is not merely a resource.
生物中心主义认为所有生物本身就具有价值。它主张每一个物种都有自身的善，并且应该得到道德关怀，而不论它对人类是否“有用”。海龟或树木不仅仅是一种资源。
Ecocentrism goes further and values whole ecosystems, including soil, water, air and ecological processes. It suggests that humans are part of a large community of life and have duties to the Earth as a whole, not only to individual creatures.
生态中心主义更进一步，认为整个生态系统，包括土壤、水、空气和生态过程，都具有价值。它主张人类是更大生命共同体的一部分，对地球整体负有责任，而不仅仅是对个别生物负有义务。
Many traditions also support the idea of stewardship. A steward is someone who looks after something on behalf of another owner. In this view, humans are caretakers of the Earth and should pass it on in good condition to future generations.
许多传统还支持管家/守护的理念。管家是代表另一个所有者照管某物的人。在这种观点下，人类是地球的照管者，应当把地球状况良好地传给后代。
2. Sustainability and Sustainable Development | 可持续性与可持续发展
Sustainability is the capacity to continue a process over a long period without exhausting the resources on which it depends. The most widely used definition of sustainable development comes from the Brundtland Report of 1987:
可持续性是指某项过程在长期内持续运行、且不耗尽所依赖资源的能力。最被广泛使用的可持续发展定义来自1987年的《布伦特兰报告》：
Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
可持续发展是既满足当代人的需要，又不损害后代人满足其自身需要能力的发展。
Sustainable development has three interconnected pillars: environmental, social and economic. Environmental quality cannot be protected if the economy produces too much pollution, and social needs cannot be met if natural resources collapse. The three pillars support each other.
可持续发展有三个相互联系的支柱：环境、社会和经济。如果经济产生过多污染，环境质量就无法得到保护；如果自然资源崩溃，社会需求也无法得到满足。这三个支柱相互支撑。
For example, sustainable forestry might maintain a steady supply of timber, protect biodiversity, support local workers and yield long-term profit. Bamboo farming, agro-forestry and certified timber are practical examples of such balance.
例如，可持续林业可以保持稳定的木材供应、保护生物多样性、支持当地工人并获得长期利润。竹林经营、农林复合系统和认证木材都是这种平衡的实际例子。
3. Carrying Capacity and Ecological Footprint | 环境承载力与生态足迹
Carrying capacity is the maximum number of organisms that an area can support without being degraded. If a population exceeds the carrying capacity of its habitat, resources such as food and water become insufficient, and waste may pollute the environment.
环境承载力是指一个区域在不退化的情况下能够支持的最大生物数量。如果一个种群超过其栖息地的承载力，食物和水等资源就会变得不足，废物也可能污染环境。
A familiar example is grassland grazing. If too many cattle are kept on a pasture, the grass cannot regrow, the soil becomes exposed, and erosion may begin. The long-term productivity of the land then falls below what the herd needs.
一个常见的例子是草场放牧。如果在同一片草地上饲养过多的牛，草就无法重新生长，土壤暴露在外，并可能开始侵蚀。土地长期的生产力就会下降到低于畜群所需水平。
The ecological footprint is a tool that measures how much land and sea area a person, city or country requires to provide the resources they use and to absorb the waste they produce. It can be compared with the Earth’s biocapacity, the available productive area.
生态足迹是一种计量工具，用来衡量一个人、一座城市或一个国家需要多少陆地和海洋面积来提供其使用的资源并吸收其产生的废物。它可以与地球的生物承载力（可用的生产性面积）进行比较。
Ecological Footprint = Demand for Resources and Waste Absorption / Biocapacity
生态足迹 = 资源需求与废物吸收量 / 生物承载力
When a population’s footprint exceeds the biocapacity of its area, it is called an ecological overshoot. The population is drawing down natural capital, such as fish stocks, groundwater and forests, faster than those resources can regenerate.
当一个群体的生态足迹超过所在区域的生物承载力时，就称为生态超载。这意味着该群体正在以快于资源再生的速度消耗自然资本，例如鱼类资源、地下水和森林。
4. Environmental Justice and Equity | 环境正义与公平
Environmental issues are not just technical problems; they are also matters of fairness. Commonly, the communities that benefit least from economic development suffer the most environmental damage. This is called environmental injustice.
环境问题不仅是技术问题，也是公平问题。通常，从经济发展中受益最少的社区，却承受着最严重的环境损害。这被称为环境不正义。
For example, polluting factories, toxic waste dumps and major highways are often located near low-income neighbourhoods or minority communities, while richer areas enjoy cleaner air, cleaner water and more green space. Fairness demands that environmental burdens and benefits be distributed more evenly.
例如，污染工厂、有毒废物堆和主干公路往往位于低收入社区或少数族群社区附近，而较富裕地区则享有更清洁的空气、更清洁的水和更多绿地。公平要求环境负担和环境利益应当更均匀地分配。
Climate justice is another aspect of environmental justice. The people most vulnerable to floods, droughts and heat waves are often poor countries that have emitted very little carbon dioxide. Powerful nations therefore have an ethical responsibility to help them adapt.
气候正义是环境正义的另一个方面。最容易遭受洪水、干旱和热浪影响的人，往往是那些二氧化碳排放量很少的贫穷国家。因此，强大国家在道义上有责任帮助它们适应气候变化。
5. Intergenerational Equity | 代际公平
Intergenerational equity means fairness between generations. It asks whether people living today should use resources and create pollution in ways that harm people who will live in fifty, one hundred or two hundred years.
代际公平是指各代人之间的公平。它追问的是：今天活着的人是否应当以损害五十年、一百年或两百年后人类的方式使用资源、制造污染。
Future generations cannot vote, sign contracts or speak in today’s debates. They rely on us to make responsible choices. This is why the guiding principle of sustainable development is so important.
未来世代不能投票、不能签订合同，也不能在今天的辩论中发言。他们只能依靠我们做出负责任的选择。这就是为什么“可持续发展”这一指导原则如此重要。
Non-renewable resources such as oil and coal are a special case. When we burn them, the resource is gone forever, and the carbon dioxide remains in the atmosphere for centuries. Using them carefully, improving energy efficiency and switching to renewable energy are ethical actions across time.
石油和煤炭等不可再生资源是一个特殊问题。当我们燃烧它们时，资源永远消失，而二氧化碳会在大气中存留数百年。谨慎使用它们、提高能源效率并转向可再生能源，正是跨越时间的伦理行动。
6. Ethical Issues in Resource Exploitation | 资源开发中的伦理问题
Natural resources such as fish, timber, minerals and freshwater are essential for human life, but they can be over-exploited if no one has a long-term responsibility. The tragedy of the commons describes this problem.
鱼类、木材、矿产和淡水等自然资源对人类生命至关重要，但如果没有人承担长期责任，它们就可能被过度开发。公地悲剧描述的就是这一问题。
Imagine a shared pasture shared by many herders. Each herder gains private profit by adding an extra animal, but the cost of overgrazing is shared by everyone. As a result, the pasture is eventually destroyed, even though no one intended that outcome.
想象一片由许多牧民共享的草地。每个牧民通过多养一头牲畜获得私人收益，但过度放牧的代价却由所有人分担。结果是，草地最终被毁坏，尽管没有一个人想造成这样的结局。
The same logic applies to many fisheries. When boats compete for the same fish stock, each boat may take as much as possible before others do. If no catch limits exist, the fish population can collapse, threatening the future of the whole fishing industry.
同样的逻辑也适用于许多渔业。当渔船竞争同一鱼类种群时，每艘船都可能在别人之前尽量多捕。如果没有捕捞限额，鱼类种群就可能崩溃，从而威胁整个渔业的前景。
Ethical solutions include shared rules, sustainable yield limits, marine protected areas and community management. These approaches respect the fact that resources belong to everyone, including future users.
符合伦理的解决方案包括共同规则、可持续产量限额、海洋保护区和社区管理。这些方法尊重一个事实，即资源属于所有人，包括未来的使用者。
7. Pollution and the Polluter Pays Principle | 污染与污染者付费原则
Pollution is an example of an external cost. The factory that releases smoke into the air may lower its own production costs, but the nearby community pays the true cost through breathing problems, cleaning bills and lost enjoyment of the environment.
污染是外部成本的一个例子。向空气中排放烟雾的工厂可能降低自身的生产成本，但附近社区却要通过呼吸问题、清洁费用和环境享受的损失来付出真正的代价。
To correct this unfairness, many governments apply the polluter pays principle. This principle states that the person or organisation responsible for pollution should pay for the damage it causes and for putting the environment right.
为了纠正这种不公平，许多政府采用污染者付费原则。该原则规定，造成污染的个人或组织应当为其造成的损害以及恢复环境的费用付费。
The principle can be put into practice through taxes on carbon emissions, charges for waste collection, fines for illegal dumping and requirements that manufacturers recycle their products. In each case, the polluter faces a financial incentive to prevent pollution.
这一原则可以通过碳排放税、垃圾收集费、非法倾倒罚款以及要求制造商回收其产品等方式付诸实践。在每种情况下，污染者都会面对预防污染的经济激励。
However, money alone cannot undo all damage. Some harm, such as the extinction of a species, is irreversible. Therefore, prevention is ethically better than cleaning up later.
然而，金钱本身并不能消除一切损害。有些伤害是不可逆转的，例如一个物种的灭绝。因此，从伦理上讲，预防胜于事后清理。
8. Biodiversity Loss and Our Responsibility | 生物多样性丧失与我们的责任
Biodiversity means the variety of living organisms in an area, including genetic diversity, species diversity and ecosystem diversity. It is being lost at hundreds of times the natural background rate because of habitat destruction, pollution, over-hunting and climate change.
生物多样性是指一个区域内生物种类的丰富程度，包括遗传多样性、物种多样性和生态系统多样性。由于栖息地破坏、污染、过度捕猎和气候变化，生物多样性正在以自然背景速率数百倍的速度丧失。
People often value biodiversity because it provides ecosystem services such as pollination, water purification, soil formation and climate regulation. When a forest or coral reef is degraded, these services are lost.
人们通常重视生物多样性，因为它提供授粉、水体净化、土壤形成和气候调节等生态系统服务。当一片森林或珊瑚礁退化时，这些服务就会丧失。
But many environmentalists argue that every species also has intrinsic value, meaning it is valuable for its own sake. A whale, a rare orchid or a small beetle does not need to benefit human beings to deserve to exist. This is a powerful ethical argument against extinction.
但许多环保主义者认为，每个物种也具有内在价值，也就是说它本身就是宝贵的。鲸、珍稀兰花或一只小甲虫并不需要造福人类才有资格存在。这是反对物种灭绝的一个有力伦理论据。
Protecting biodiversity therefore involves both practical and moral commitments: preserving habitats, controlling invasive species, reducing pollution and respecting the natural world as a community of life, not a warehouse of goods.
因此，保护生物多样性既涉及实际行动，也涉及道德承诺：保护栖息地、控制入侵物种、减少污染，并把自然世界视为一个生命共同体，而不是一个货物仓库。
9. Climate Change and Ethical Responsibility | 气候变化与伦理责任
Climate change is often described as the greatest ethical challenge of our time. It is caused mainly by the release of greenhouse gases such as carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O). These gases come from burning fossil fuels, deforestation, agriculture and industry.
气候变化常常被称为当代最大的伦理挑战。它主要是由二氧化碳（CO₂）、甲烷（CH₄）和一氧化二氮（N₂O）等温室气体的排放造成的。这些气体来自化石燃料燃烧、森林砍伐、农业和工业。
Historically, the richest countries have emitted the most greenhouse gases, whereas the poorest countries are likely to suffer the earliest and most severe effects. This creates an issue of common but differentiated responsibilities: all countries should act, but richer countries should lead the way and provide support.
从历史上看，最富裕国家排放的温室气体最多，而最贫穷国家却可能最早、最严重地受到气候影响。这就产生了共同但有区别的责任问题：所有国家都应行动，但较富裕国家应率先行动并提供支持。
Individuals also face ethical choices. Flying, eating beef, or leaving lights on all add to carbon footprints, but people have different levels of choice. Governments and corporations must create systems that make the responsible choice the easiest choice.
个人也面临伦理选择。乘飞机、吃牛肉或让灯长亮都会增加碳足迹，但人们的选择余地并不相同。政府和企业必须创建制度，让负责任的选择成为最容易的选择。
10. Decision-Making and Environmental Policy | 决策与环境政策
Ethical values should be built into environmental decision-making. One important tool is the environmental impact assessment (EIA), which is carried out before major projects such as dams, mines and motorways are approved. It asks what harm might be done and how it could be reduced.
伦理价值观应被纳入环境决策之中。一个重要工具是环境影响评价（EIA），它在大坝、矿山和高速公路等重大项目获批之前进行。它要回答的问题是：可能会造成什么损害？如何减少这种损害？
Another tool is cost-benefit analysis, which tries to measure the economic value of a project and compare it with the damage caused. However, it is difficult to put a price on a healthy river, an endangered species or people’s cultural traditions. Ethical analysis must go beyond numbers.
另一个工具是成本效益分析，它试图衡量一个项目的经济价值，并与所造成的损害进行比较。然而，很难为一条健康的河流、一个濒危物种或人们的文化传统定价。伦理分析必须超越数字。
The precautionary principle is also ethically important. It states that if an action may cause serious or irreversible harm, scientific uncertainty should not be used as a reason to postpone protective measures.
预防原则也具有重要伦理意义。它指出，如果某项行动可能造成严重或不可逆转的损害，就不能以科学不确定性为由推迟采取保护措施。
Good environmental governance also requires public participation. People who live near a project should be informed, consulted and allowed to express their views. This respects their rights and improves the quality of decisions.
良好的环境治理还要求公众参与。居住在项目附近的人们应当被告知、征询并允许表达意见。这既尊重了他们的权利，也提高了决策质量。
11. Environmental Ethics in Daily Life | 日常生活中的环境伦理
Environmental ethics is not only for governments and scientists; it is also personal. Daily choices such as saving electricity, reducing food waste, choosing public transport, avoiding single-use plastics and buying less have real environmental effects.
环境伦理不仅仅是政府或科学家的事，它也是个人的事。节约用电、减少食物浪费、选择公共交通、避免一次性塑料和少买不必要的东西等日常选择，都会产生真实的环境影响。
We can also ask whether a product was made in a way that respects workers and ecosystems. Ethical consumption means considering the hidden social and environmental costs behind every item we buy.
我们还可以追问一件产品的生产方式是否尊重工人和生态系统。伦理消费意味着考虑我们购买的每件物品背后隐藏的社会与环境成本。
At the same time, personal choices alone are not enough. Citizens, scientists, media, businesses and governments must work together. Reducing human impacts requires both changed lifestyles and changed systems.
同时，仅靠个人选择是不够的。公民、科学家、媒体、企业和政府必须共同努力。减少人类影响既需要改变生活方式，也需要改变制度体系。
12. Conclusion: Living Responsibly | 结语：负责任地生活
Environmental problems force us to ask deep questions about values. If we see nature only as a resource, we may exploit it to destruction. If we recognise that humans, species and future generations have rights, we are more likely to protect the planet.
环境问题迫使我们追问关于价值的深层问题。如果我们只把自然视为资源，就可能在开发中将其毁灭；如果我们认识到人类、物种和未来世代都拥有权利，就更有可能会保护地球。
Ethical environmental management is guided by fairness, precaution, stewardship and hope. It recognises that our actions today create the world of tomorrow. It is not enough to know how nature works; we must also decide how we ought to live within it.
符合伦理的环境管理以公平、预防、守护和希望为指引。它认识到我们今天的行为正在创造明天的世界。仅仅知道自然如何运转是不够的；我们还必须决定，我们应当如何在地球家园中生活。
By combining scientific understanding with strong ethical values, we can meet human needs while protecting the living world for generations to come.
只有把科学认识与坚定的伦理价值观结合起来，我们才能在满足人类需要的同时，为子孙后代保护这个生命世界。
