“Well, lots of people recognize that as humans get older they tend to have less and less children...trees do it the other way around.”
“是的，很多人认为，人类随着年龄的增长，繁殖能力会降低…而树木却正相反。”
David Lindenmayer. He studies conservation, landscape ecology and biodiversity at the Australian National University College of Science in Canberra. On January 26th he spoke to Scientific American Editor in Chief Mariette DiChristina when they were both at the World Economic Forum in Davos.
大卫·林登迈耶如是说。他在位于堪培拉的澳大利亚国立大学科学学院研究自然保护、景观生态学和生物多样性。在1月26日的达沃斯世界经济论坛上，他与科学美国人的杂志主编马里埃特·迪克里斯蒂娜（Mariette DiChristina）进行了交谈。
DL: “What happens is that the older some of these really big old trees get, the more seeds they produce and the more germinants they’re likely to have. So it’s actually the polar opposite of what we see with humans and most other animals, so really quite extraordinary.”
大卫：“事实是，这些很大的古树越古老，它们就会产生越多的种子，而且可能长出更多的萌芽。因此，这实际上与我们人类和其他大多数动物截然相反，所以真的非常特殊。”
Mariette DiChristina: “And how about the number of older trees that we have today, how does that look?”
马里埃特·迪克里斯蒂娜：“那么现在我们拥有的古树的数量怎么样呢，状况如何？”
DL: “It’s quite a distressing situation, because in many, many forests and woodland and other ecosystems around the world, populations of large old trees are declining very, very quickly. And this matters because a lot of biodiversity, a lot of carbon, a lot of key ecosystem processes are associated with those really big, old trees.”
大卫：“目前的状况十分令人痛心，因为在全世界的许许多多森林和林地以及其他的生态系统，大古树的数量正在飞速减少。这很重要，因为很多生物多样性，很多碳，很多重要生态系统过程都与这些很大的古树息息相关。”
MD: “Is there something we can do about this?”
迪克里斯蒂娜：“有什么我们能做的吗？”
DL: “Absolutely there is. We can make sure we grow more forest, we can make sure we protect the big trees that we have now, and we can make sure that we don’t do things that really put a lot of pressure on those trees. Straight out, just cutting them down—we should not be cutting down really big, old trees anymore.”
大卫：“当然有。我们可以确保种植更多的森林，我们可以确保我们保护我们现有的大树，而且我们可以确保我们不做出施压于那些树木的事情。直白地说就是砍伐它们——我们不应该再砍掉那些很大很古老的树木。”
