you can isolate it, and it works very much like carbon fiber.
你可以對它進行分離，它的性質跟碳纖維非常相似。
So, take that from a tree, form it into fibers, and then those fibers can strengthen things, such as airplanes, buildings, cars.
從樹木中提取纖維素，接著再制成纖維，然后這些纖維能用來加固東西，例如飛機、建筑物、汽車。
The advantage of this, though, is it's not just bioderived, comes from a renewable resource,
這一做法的優點是，納米纖維不僅僅來自于可再生的生物資源，
but also that it is transparent, so it can be used in consumer electronics, as well as food packaging.
同時它還是透明的，因此可以應用在消費電子產品和食品包裝上。
Not bad for something that basically comes from the backyard.
這種再利用還不錯吧！
Another one from the biosource is synthetic spider silk.
另一種來自生物界的材料是合成蜘蛛絲。
Now, it's very hard to actually create spider silk naturally,
用天然的方法制造蜘蛛絲是很難的，
you can basically get it from spiders, but in large numbers, they tend to kill each other,
你只能從蜘蛛獲得蜘蛛絲，但蜘蛛數量多了，它們會自相殘殺，
eat each other, so you've got a problem with creating it, in the same way you do with regular silk.
互相蠶食，所以如果你像收集蠶絲那樣去收集蜘蛛絲的話，就會遇到問題。
So what you can do is instead take the DNA from the spider, and put it into various different things.
那么，你可以做的就是從蜘蛛中提取DNA，并將它放到不同的地方培養。
You can put it into bacteria, you can put it into yeast, you can put it into milk.
你可以把它放到細菌里，放到酵母里，放到牛奶里。
And what you can do then is, the milk or the bacteria produce in much larger volumes and then from that,
之后，你能做的是，當牛奶或細菌產生大量的絲狀物后，
spin a yarn and then create a fabric or a rope. Again, bioderived, has incredible strength -- about the same as Kevlar,
提取出來紡紗，接著制作織物或繩子。它來源于生物，有著驚人的強度，大約和芳綸纖維一樣強，
so they're using it in things like bulletproof vests and helmets and outdoor jackets.
因此可以用來制作防彈背心和頭盔，以及戶外夾克。
It has a great performance. But again, it's bioderived, and at the end of its life, it potentially can go back into the soil
性能十分出眾。但別忘了，這是生物衍生物，當它不再有使用價值時，就可以變成土地里的肥料，
and get composted to again be potentially used as a new material.
作為一種新的東西重新被利用。
I'd like to leave you with one last form which is biobased, but this, I think, is like the ultimate thrift.
最后，我還想給你們介紹一種基于生物的產品，而我覺得，這才是終極的節儉。
Think about the poster child for conspicuous consumption. It's the water bottle.
想想揮霍式消費的典型代表，那就是礦泉水瓶。
We have too many of them, they're basically going everywhere, they're a problem in the ocean.
我們有非常多的這樣的水瓶，它們無處不在，是海洋污染重要來源之一。
