In 2019, humanity received a warning:
2019年，人类了收到一个警告：
30 of the world's leading scientists released the results of a massive three-year study into global agriculture
30位世界顶尖的科学家发布了一项对全球农业长达三年的研究结果，
and declared that meat production is destroying our planet and jeopardizing global health.
宣称肉类的生产正在摧毁我们的家园，并危害全球安全。
One of the study's authors explained that "humanity now poses a threat to the stability of the planet ...
该研究的一位作者解释说：“人类正在危害地球的稳定...
nothing less than a new global agricultural revolution."
我们需要一场新的世界农业革命。”
As somebody who's spent the last two decades advocating a shift away from industrial meat production,
作为一个把过去二十年的时间都花在倡议工业肉类生产转型的人，
I wanted to believe that this clarion call was going to make a difference.
我曾经相信这个号召会带来些许改变。
The thing is, I've seen this sort of thing again and again and again for decades.
然而，几十年来此类事件还是反复发生。
Here's 2018 from the journal "Nature," 2017 from "Bioscience Journal," 2016 from the National Academy of Sciences.
这是2018年《自然》杂志的一篇文章，这是2017年《生物科学杂志》的一篇文章，这是2016年《美国科学院学报》上的文章。
The main point of these studies tends to be climate change.
这些研究的重点都是气候变化。
But antibiotic resistance represents just as big of a threat.
但抗生素耐药性也是一个很大的威胁。
We are feeding massive doses of antibiotics to farm animals.
我们给农场动物喂食大量的抗生素。
These antibiotics are then mutating into superbugs that threaten to render antibiotics obsolete within all of our lifetimes.
这些抗生素随后转变为超级细菌，使得我们有生之年研究出的抗生素都不再有效。
You want a scare? Google: "the end of working antibiotics."
想知道后果吗？可以去谷歌一下：“有效抗生素的终结”。
I'm going to get one thing out of the way: I am not here to tell anybody what to eat.
我想说明的是：我不是来教大家该吃什么的。
Individual action is great, but antibiotic resistance and climate change -- they require more.
个体行为固然很好，但是要解决抗生素耐药性和气候变化问题--这还远远不够。
Besides, convincing the world to eat less meat hasn't worked.
并且，劝大家少吃肉是没有效果的。
For 50 years, environmentalists, global health experts and animal activists have been begging the public to eat less meat.
50多年来，环境学家，国际卫生专家以及动物保护者一直苦口婆心地劝告大家少吃肉。
And yet, per capita meat consumption is as high as it's been in recorded history.
然而，人均肉类消耗量自有历史记载以来一直都居高不下。
The average North American last year ate more than 200 pounds of meat. And I didn't eat any.
去年北美人均消耗肉类200多磅。我可一点肉都没吃。
Which means somebody out there ate 400 pounds of meat.
这意味着有人吃了400磅。
On our current trajectory, we're going to need to be producing 70 to 100 percent more meat by 2050.
以目前的趋势来看，到2050年，我们生产的肉类要比现在多70％-100％。
This requires a global solution.
这个问题需要全人类一起解决。
What we need to do is we need to produce the meat that people love,
我们需要做的是，生产人们喜爱的肉类，
but we need to produce it in a whole new way. I've got a couple of ideas.
不过我们要以一种全新的方式生产。我有几个主意。
Idea number one: let's grow meat from plants.
其一：从植物中生产肉。
Instead of growing plants, feeding them to animals, and all of that inefficiency,
不再把植物当作动物饲料，那样效率太低了。
let's grow those plants, let's biomimic meat with them, let's make plant-based meat.
我们可以种植物，然后仿生肉类，做出素肉。
Idea number two: for actual animal meat, let's grow it directly from cells.
其二：如果想做真的肉，我们可以用细胞培育。

Instead of growing live animals, let's grow the cells directly.
而不是养殖牲畜，我们直接培育细胞。
It takes six weeks to grow a chicken to slaughter weight.
将鸡养到可以屠宰的重量需要六周。
Grow the cells directly, you can get that same growth in six days.
直接培育细胞的话，要达到同样大小，只需六天。
This is what that looks like at scale. It's your friendly neighborhood meat brewery.
这就是规模化的生产过程。就像是你家附近美妙的肉类“啤酒厂”。
I want to make two points about this. The first one is, we believe we can do it.
我想说的有两点。一是：我们相信我们能够做到。
In recent years, some companies have been producing meat from plants that consumers cannot distinguish from actual animal meat,
近年来，有些公司已经在生产素肉了，消费者分别不出素肉和真肉口感的区别，
and there are now dozens of companies growing actual animal meat directly from cells.
并且，有一批工厂已经直接从细胞中生产肉类。
This plant-based and cell-based meat gives consumers everything that they love about meat
素肉和细胞肉能还提供消费者喜爱的关于肉的一切--
the taste, the texture and so on
味道，质地，等等，
but with no need for antibiotics and with a fraction of the adverse impact on the climate.
但不需要抗生素，对地球气候也只有很小的影响。
And because these two technologies are so much more efficient, at production scale these products will be cheaper.
由于这两项技术生产肉类效率如此高，如果大规模生产，肉类产品会更便宜。
But one quick point about that -- it's not going to be easy.
但是要知道，这项技术不那么简单。
These plant-based companies have spent small fortunes on their burgers,
生产素肉的公司已经在产品上投入大笔资金，
and cell-based meat has not yet been commercialized at all.
细胞肉也没有完全进入市场。
So we're going to need all hands on deck to make these the global meat industry.
所以我们需要所有人共同努力，来建造全球范围的产业。
For starters, we need the present meat industry.
首先，我们仍需要现存的肉类产业。
We don't want to disrupt the meat industry, we want to transform it.
我们不想干扰肉类产业，我们想要它转型。
We need their economies of scale, their global supply chain, their marketing expertise and their massive consumer base.
我们需要他们的经济规模，他们的全球供应链，营销技术，以及广大消费者的基础。
We also need governments.
我们还需要各国政府的支持。
Governments spend tens of billions of dollars every single year on research and development focused on global health and the environment.
各国政府每年在全球健康和环境方面的研究和开发上花费了数百亿美元。
They should be putting some of that money into optimizing and perfecting the production of plant-based and cell-based meat.
他们应该把部分资金用来优化和完善素肉和细胞肉的生产。
Look, tens of thousands of people died from antibiotic-resistant superbugs in North America just last year.
在北美，仅仅去年一年，就有数以万计的人们死于有抗生素耐药性的超级病菌。
By 2050, that number is going to be 10 million per year globally.
到2050年，该数字会达到每年全球数千万。
And climate change represents an existential threat to huge portions of our global family,
还有，气候变化对全球很多家庭构成了毁灭性的威胁，
including some of the poorest people on the face of the planet.
这里面包括一部分全球最贫困人口。
Climate change, antibiotic resistance -- these are global emergencies.
气候变化、抗生素耐药性都是全球性紧急事件。
Meat production is exacerbating these emergencies on a global scale.
肉类生产恶化了它们的紧急程度。
But we are not going to decrease meat consumption
但我们不会减少肉类消耗，
unless we give consumers alternatives that cost the same or less and that taste the same or better.
除非我们能提供给消费者一些同样价钱或更加便宜，口味相同或更好的替代品。
We have the solution. Let's make meat from plants. Let's grow it directly from cells.
我们有解决方案。让我们用植物生产肉，或直接用细胞培育。
It's past time that we mobilize the resources that are necessary to create the next global agricultural revolution. Thank you.
我们已经动用了所需的资源，是时候进行下一场全球农业革命了。谢谢。
