- Not only that, we're continuing to plant one or two species and weed out the aspens and birches.
- 不仅如此,我们还在继续种植着那一两种单一的树木,还继续着把山杨和桦树清除出去。
- These simplified forests lack complexity,
- 这种单一的树木种类使森林缺少了多样性,
- and they're really vulnerable to infections and bugs.
- 这让它们在传染病和虫害面前根本不堪一击。
- And as climate changes, this is creating a perfect storm
- 随着气候变化,这也将会为一些极端事件
- for extreme events, like the massive mountain pine beetle outbreak that just swept across North America,
- 带来一场疯狂的风暴,比如刚刚席卷整个北美洲的山松甲虫大爆发,
- or that megafire in the last couple months in Alberta.
- 还有过去几个月在阿尔伯塔的森林大火。
- So I want to come back to my final question:
- 所以现在我想提我的最后一个问题:
- instead of weakening our forests, how can we reinforce them and help them deal with climate change?
- 与破坏我们的森林相反,我们怎么才能让它们变得更强大,怎么才能帮助它们应对气候变化呢?
- Well, you know, the great thing about forests as complex systems is they have enormous capacity to self-heal.
- 其实你们知道吗,森林作为一个复杂的系统,最好的一点就是它们拥有相当强大的自愈能力。
- In our recent experiments, we found with patch-cutting and retention of hub trees
- 在我们最近几个实验中,我们发现小规模的砍伐,把中心树保护好,
- and regeneration to a diversity of species and genes and genotypes
- 物种多样性、基因和基因型多样性的再生,
- that these mycorrhizal networks, they recover really rapidly.
- 加上这些真菌网络的存在,会使森林的恢复速度变得无比迅速。
- So with this in mind, I want to leave you with four simple solutions.
- 所以出于这种考虑,我想提出四个简单的解决方法。
- And we can't kid ourselves that these are too complicated to act on.
- 而且我们一定不能自欺欺人,因为这些做起来其实也挺复杂的。

三毛说“如果有来生,要做一棵树,站成永恒,没有悲伤的姿势:一半在尘土里安详,一半在空中飞扬;一半散落阴凉,一半沐浴阳光。非常沉默非常骄傲,从不依靠从不寻找。”但是你知道吗?其实大树并不沉默。在地下存在着另外一个世界,它们使得无数的大树可以彼此交流,一片森林表现的像一个整体。它们是如何做到的呢?来一起且听树语。
