How much damage are humans doing to planet Earth?
人类对地球的伤害有多大？
That's the key question in a report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, or IPBES.
这是生物多样性和生态系统服务政府间科学-政策平台（IPBES）报告中出现的主要问题。
The headlines are stark.
标题很醒目。
Nature in all its diversity is declining at rates unprecedented in human history.
在人类历史上，所有自然多样性正在以前所未有的速度下降。
And more than one million species are directly threatened with extinction,
超100万种物种直接遭到灭绝风险，
from our closest cousins to most of the largest inhabitants of our oceans, skies, and ground.
从最近的表亲到多数栖息在海洋、天空以及陆地的大型动物。
We've lost much of our native forests, much of our native wetlands
我们失去了大部分的原始森林，大部分的原始湿地，
and effectively biodiversity needs to be considered as an equally important issue as climate change.
实际上生物多样性和气候变化是同等重要的。
It's not just an environmental issue, it is an economic issue, a development issue, a security issue,
这不仅仅是环境问题，这是经济问题，发展问题，安全问题，
social, moral and ethical issue. The time for action clearly is now.
社会，道德和伦理问题，我们需要马上采取行动了。
The report concludes that land based species have declined by at least 20 percent, mostly since 1900.
该报告总结道，陆地生物减少了至少20%，多数是1990年以后减少的。
Amphibian species have declined by more than 40% during that period, and more than a third of all marine mammals are threatened.
两栖动物在这期间减少了40%多，超三分之一的海洋哺乳动物遭受威胁。
And human activites, from ocean pollution and overfishing
而人类活动，从海洋污染，过度捕捞，
to human caused climate change and land degradation from farming and logging, are the primary reason it's all happening.
到人类引发的气候变化，农耕和伐木引起的土地退化，这些都是发生这些事情的主要原因。
The consensus among the 150 nations that approved the report, including the U.S., is clear: something has to change.
150个国家赞同这份报告，他们的共识很清晰，那就是做出改变，这包括美国。
Business as usual is a disaster. We're gonna continue to change the climate.
如果我们按往常的做法继续，那将是一场灾难，气候变化还会继续。
We're gonna continue to lose biodiversity but we can have a more sustainable future if we choose the right policies, the right technologies.
生物多样性还会继续恶化，但如果我们选对了政策，选对了技术，我们还会拥有可持续发展的未来。
If we change our behavior we can have a much more sustainable future for our children and grandchildren.
如果我们改变行为，我们还会为子孙后代创造一个可持续发展的未来。
The solution the authors say is to begin thinking of all forms of nature, from giraffes and elephants to lizards and birds, as having value.
报告撰写者称解决方法是将各种自然形态看成是有价值的，从长颈鹿，大象到蜥蜴和鸟类。
Adding their value into our own attempts to clean up the mess we've made can solve the problem, they say.
他们称将它们的价值融入到处理这一问题的努力中，我们可以解决这一问题。
We need to have incentives in place for clean technologies, clean practices.
我们需要鼓励使用清洁技术，在清洁上展开行动。
We need to recognize not just GDP, Gross Domestic Product, as a measure of growth, economic growth,
我们不仅仅需要认识到GDP（国内生产总值）是经济增长的衡量标准，
we have to recognize that nature is a major thing of natural capital, along with human capital, built capital and social capital.
我们还需要认识到自然在自然资本，人类资本，建造资本和社会资本上起到的重要作用。
The report concludes that is still possible to head off the worst predicted outcomes
这份报告总结道，人类依然有可能避免预期的最坏结果，
if humans start moving aggressively towards sustainability.
如果人类开始大幅度向可持续发展进发。
