Climate change is becoming a problem you can taste Amanda Little

In the early months of the pandemic,

chef José Andrés circulated two photos

that have come to symbolize
a modern American food crisis.

The first shows mountains of potatoes

that have been left to rot
in a field in Idaho.

The restaurants and cafeterias
and stadiums that had consumed them

were shuttered during the pandemic.

The second shows a devastating scene
outside of the San Antonio food bank.

Thousands of carloads of people lined up,

waiting for food with not enough
supply to go around.

“How is it possible these two photos
exist at the same time,

in the most prosperous

and technologically advanced
moment in our history,” tweeted Andrés.

In the months after
the photos were published,

the crisis got worse.

Billions of pounds of potatoes
and other fresh produce

were chucked by American farmers.

At the same time,

food banks all over the country
were reporting demand increases

and 40 percent were facing
critical shortfalls.

Outside the US,

especially in the Middle East
and throughout Southeastern Africa,

COVID-19 was paralyzing food systems
that were already vulnerable.

Oxfam has predicted
that by the end of 2020

12,000 people per day could die
of hunger related to COVID.

That’s more than the highest
daily mortality rate

recorded so far.

But what’s worse

and what’s much more
concerning to all of us

is that COVID is just one
of many major disruptions

that have been predicted

in the years and decades ahead.

More chronic and complex
than the pressures of COVID

are the pressures of climate change.

And those of you who live in California
have seen this on your farms.

You’ve seen withering heat
and drought and fires

disrupt avocado and almond
and citrus and strawberry farms.

This summer, we saw
the devastating impacts of storms

on corn and soy farms.

I’ve seen the various
pressures of drought,

heat, flooding, superstorms,

invasive insects, bacterial blight,

shifting seasons and weather volatility

from Washington to Florida,

and from Guatemala to Australia.

The upshot is this.

Climate change is becoming
something we can taste.

This is a kitchen-table issue
in the literal sense.

The International Panel on Climate Change

has predicted that by mid-century

the world may reach a threshold
of global warming

beyond which current
agricultural practices

can no longer support
large human civilizations.

The USDA scientist Jerry Hatfield
put it to me this way:

the single biggest threat
of climate change

is the collapse of food systems.

The reality we face,

one that was exposed
by those mountains of potatoes

and the cars lined up during the pandemic,

is that our supply chains are antiquated.

Our food systems have not been designed

to adapt to major disruptions
or preempt them.

Addressing this challenge
as much as any other

is going to define our progress
in the coming century.

But there’s good news.

And the good news is that farmers
and entrepreneurs and academics

are radically rethinking
national and global food systems.

They are marrying principles
of old-world agroecology

and state-of-the-art technologies

to create what I call
a third way to our food future.

We’re going to see radical changes

in what we grow and how we eat
in the coming decades,

as these environmental and population

and public health pressures intensify.

I studied these changes
for my book “The Fate of Food:

What We’ll Eat in a Bigger,
Hotter, Smarter World.”

I traveled for five years
into the lands and the minds

and the machines that are shaping
the future of food.

My travels took me
through 15 countries and 18 states,

from apple orchards in Wisconsin
to tiny cornfields in Kenya,

to massive Norwegian fish farms

and computerized foodscapes in Shanghai.

I investigated new ideas,

like robotics and CRISPR
and vertical farms.

And old ideas, like edible insects
and permaculture and ancient plants.

I began to see the emergence
of this third way to food production.

A synthesis of the traditional
and the radically new.

There’s a growing controversy

about the best path
to future food security in the US.

Food is ripe for reinvention,
Bill Gates has proclaimed.

Huge flows of investment

are funding new methods of climate-smart
and high-tech agriculture.

But many sustainable food advocates
bristle at this idea of reinvention.

They want food deinvented.

They argue for a return to preindustrial

and pre-green revolution,

biodynamic and organic farming.

To which skeptics inevitably respond,

“Nice, but does it scale?

Sure, a return to traditional
farming methods

could produce better food,

but can it produce enough food
that’s affordable?”

The rift between the reinvention camp
and the deinvention camp

has existed for decades.

But now it’s a raging battle.

One side covets the past,

the other side covets the future

and as someone observing this
from the outside,

I began to wonder,
why must it be so binary?

Can’t there be a synthesis
of the two approaches?

Our challenge is to borrow
from the wisdom of the ages,

and from our most advanced science,

to forge this third way.

One that allows us
to improve and scale our harvests,

while restoring rather than degrading

the underlying web of life.

I belong to neither camp.

I’m a failed vegan
and a lapsed vegetarian,

and a terrible backyard farmer.

If I’m honest,

I will keep trying at this,
but I may fail.

But I’m hell-bent on hope,

and if my travels have taught me anything,

it’s that there’s good reason for hope.

Plenty of solutions are merging

that can help build sustainable,
resilient food systems.

Even if we can’t rely on a critical mass

of backyard-farming vegetarians
to do this on their own,

from the ground up.

Let’s start with artificial
intelligence and robotics.

Jorge Heraud is a Peruvian-born engineer

who now lives in Silicon Valley,

and his company developed
a robotic weeder named See and Spray,

and I went to Arkansas to see
the maiden voyage of See and Spray.

And I was half expecting
a battalion of C3PO-style robots

to march into the fields
with pincer hands to pluck the weeds.

And instead, I found this.

A tractor with a big, white
hoop skirt off the back of it.

And inside that hoop skirt are 24 cameras

that use computer vision
to see the ground beneath

and to distinguish between
the plants and the weeds.

And to deploy with sniper-like precision

these tiny jets
of concentrated fertilizer,

or herbicide,

that incinerate the baby weeds.

I learned how robotics
can end the practice

of broadcast spraying chemicals
across millions of acres of land

and how we can reduce
the use of herbicides

by up to 90 percent.

But the bigger picture
is even more exciting.

Intelligent machines
can treat plants individually,

applying not just herbicides

but fungicides and insecticides

and fertilizers on a plant-by-plant,
rather than field-by-field basis.

So that eventually,

this kind of hyperspecific farming

can allow for more diversity
and intercropping on fields.

And big farms can begin
to mimic natural systems

and improve soil health.

Heraud is the embodiment
of third-way thinking, right?

Robots, he told me,

don’t have to remove us from nature,

they can bring us closer to it,
they can restore it.

Increasing crop diversity will be crucial

to building resilient food systems.

And so will decentralizing agriculture

so that when farmers
in one region are disrupted,

the others around, they can keep growing.

The rise of vertical farms,

like this farm, built inside
a former steel mill in Newark, New Jersey,

can play a key role
in decentralizing agriculture.

Aeroponic farms use a tiny fraction

of the water that is used
in in-ground farms.

And they can grow food much faster,
about 40 percent faster.

And when located in and near cities,

where the food is consumed,

they eliminate a huge amount
of trucking and food waste.

It struck me at first as creepy

in kind of a “Silent Running” way

that we’d be growing
our future fruits and vegetables

inside, without soil or sun.

And after weeks of spending time
in these plant factories,

I began to see it as oddly,
almost perfectly natural

to deliver the plants
only and exactly what they need,

with zero herbicides
and radical efficiency.

Here again, we see innovators
borrowing from,

and perhaps even elevating
the wisdom of natural ecosystems.

Developments in plant-based
and alternative meats

are also profoundly hopeful.

And they follow a similar trend

toward local, resilient,
low-carbon protein production.

Consumers are excited about this,

and during the pandemic,

we’ve seen a 250 percent increase

in demand for alternative meats.

A study by the Journal
of Clinical Nutrition

found that the participants
who were eating the plant-based proteins

saw a drop in their cholesterol levels,

in their weight

and eventually, a drop
in their risk of heart disease.

The potential environmental benefits
of plant-based meats are astounding.

And there’s even potential
in lab-grown or cell-based meats.

Uma Valeti fed me my first plate
of lab-grown duck breast,

harvested fresh from a bioreactor.

It had been grown
from a small sampling of cells

taken from muscle tissue and fat
and connective tissues,

which is exactly what we eat
when we eat meat.

This lab-grown or cell-based duck meat

has very little threat
of bacterial contamination,

it’s about 85 percent lower CO2
emissions associated with it.

Eventually it can be grown

like those crops inside vertical farms
in decentralized facilities

that aren’t vulnerable
to supply-chain disruptions.

Valeti started out as a cardiologist,

who understood that doctors
have been developing

human and animal tissues
in laboratories for decades.

He was inspired as much by that

as he was by a 1931 quote
from Winston Churchill that says,

“We shall escape the absurdity
of growing the whole chicken

in order to eat the breast or the wing,

by growing them separately
in suitable mediums.”

Like Heraud, Valeti is
a quintessential third-way thinker.

He’s reimagined an old idea
using new technology,

to usher in a solution
whose time has come.

I’ve met with dozens of farmers
and entrepreneurs and engineers

who emulate third-way thinking,
all over the world.

They’re using modern
breeding tools like CRISPR

to develop nutritious heirloom crops
that can withstand drought and heat.

They’re using AI to make
aquaculture sustainable.

They’re finding ways
to eliminate food waste.

They are scaling up

conservation agriculture
and managed grazing.

And they’re reviving ancient plants,

and they’re recycling
sewage and gray water

to develop a drought-proof water supply.

The upshot is this:

Human innovation that marries
old and new approaches to food production

can, and I believe, will
usher in this third way

and redefine sustainable food
on a grand scale.

在大流行的最初几个月,

厨师 José Andrés 散发了两张

象征现代美国粮食危机的照片。

第一个显示

了在爱达荷州的一块田地里腐烂的土豆山。 在大流行期间,消耗它们

的餐馆、自助餐厅
和体育场馆

都关闭了。

第二个展示
了圣安东尼奥食品银行外的毁灭性场景。

成千上万的人排队

等候食物
供应不足。

“这两张照片怎么可能
同时存在,

在我们历史上最繁荣

和技术最先进的
时刻,”安德烈斯在推特上写道。

在照片发布后的几个月里

,危机变得更糟。 美国农民丢弃了

数十亿磅土豆
和其他新鲜

农产品。

与此同时,

全国各地的食品银行
都报告需求增加,

而 40% 的食品银行面临
严重短缺。

在美国以外,

特别是在中东
和整个非洲东南部,

COVID-19 正在使本已脆弱的粮食系统陷入瘫痪

乐施会预测
,到 2020 年底,

每天可能有 12,000 人死于
与新冠病毒相关的饥饿。

这超过了迄今为止记录的最高
每日死亡率

但更糟糕

、更让
我们所有人

担忧的是,COVID 只是

未来几年和几十年预测的众多重大破坏之一。

气候变化的压力比 COVID 的压力更长期和复杂。

你们这些住在加利福尼亚的人
已经在你们的农场看到了这一点。

你已经看到了酷热
和干旱,大火

破坏了鳄梨、杏仁
、柑橘和草莓农场。

今年夏天,我们看到
了风暴

对玉米和大豆农场的破坏性影响。 从华盛顿到佛罗里达,从危地马拉到澳大利亚,

我看到
了干旱、

高温、洪水、超级风暴、

入侵昆虫、细菌枯萎病、

季节变化和天气波动等各种压力

结果是这样的。

气候变化正在成为
我们可以品尝到的东西。

这是字面意义上的餐桌问题

国际气候变化专门

委员会预测,到本世纪

中叶,世界可能会达到全球变暖的阈值

超过该阈值,当前的
农业实践

将无法再支持
大型人类文明。

美国农业部科学家杰里哈特
菲尔德这样告诉我:气候变化

的最大威胁

是粮食系统的崩溃。

在大流行期间,那些堆积如山的土豆和排队的汽车暴露了我们面临的现实

是,我们的供应链已经过时了。

我们的食品系统并非

旨在适应重大破坏
或先发制人。

与其他任何挑战一样多地应对这一挑战

将决定我们
在下个世纪的进步。

但有好消息。

好消息是农民
、企业家和学者

正在从根本上重新思考
国家和全球粮食系统。

他们将
旧世界农业生态学的原则

和最先进的技术结合

起来,创造出我所说
的通往我们食品未来的第三种方式。 随着这些环境、人口和公共卫生压力的加剧,

我们将在未来几十年

看到我们的种植方式和饮食方式发生根本变化


为我的书“食物的命运:

我们将在更大、
更热、更智能的世界吃什么”研究了这些变化。

我花了五年时间游历了塑造食品
未来的土地、思想

和机器

我的旅行带我
穿越了 15 个国家和 18 个州,

从威斯康星州的苹果园
到肯尼亚的小玉米地,

再到挪威的大型养鱼场

和上海的计算机化美食景观。

我研究了新的想法,

比如机器人技术、CRISPR
和垂直农场。

还有一些古老的想法,比如食用昆虫
、永续农业和古老的植物。

我开始看到
第三种粮食生产方式的出现。

传统
与全新的综合体。

关于

美国未来食品安全的最佳途径的争议越来越大。 比尔·盖茨宣称

,重塑食物的时机已经成熟

大量投资

正在资助气候智能型
和高科技农业的新方法。

但许多可持续食品
倡导者对这种重新发明的想法感到愤怒。

他们希望对食物进行改造。

他们主张回归前工业化

和前绿色革命、

生物动力和有机农业。

对此,怀疑论者不可避免地会回答:

“很好,但它会扩大规模吗?

当然,回归传统
耕作方法

可以生产出更好的食物,

但它能生产出足够多
负担得起的食物吗?”

再发明阵营和再发明阵营之间的裂痕

已经存在了几十年。

但现在是一场激烈的战斗。

一方觊觎过去

,另一方觊觎未来

,作为
旁观者,

我开始怀疑,
为什么一定要如此二元?

不能
综合这两种方法吗?

我们的挑战是
借用时代的智慧

和我们最先进的科学

来打造第三条道路。

它使我们
能够提高和扩大收成,

同时恢复而不是

降低潜在的生命网络。

我不属于任何一个阵营。

我是一个失败的素食主义者
,一个失败的素食主义者

,一个糟糕的后院农民。

老实说,

我会继续努力,
但我可能会失败。

但我一心希望

,如果我的旅行教会了我什么,

那就是有充分的理由抱有希望。

许多解决方案正在融合

,可以帮助建立可持续的、有
弹性的粮食系统。

即使我们不能依靠大量

的后院素食者
从头开始自己做这件事

让我们从
人工智能和机器人技术开始。

Jorge Heraud 是一位秘鲁裔工程师

,现居硅谷

,他的公司开发
了一款名为 See and Spray 的机器人除草机

,我去阿肯色州观看
了 See and Spray 的处女航。

我有一半期待
一队 C3PO 式机器人

用钳子手进入田野拔除杂草。

相反,我发现了这个。

拖拉机,后面有一条白色的大
箍裙。

在那条环形裙子里面有 24 个摄像头

,它们使用计算机视觉
来观察下面的地面,


区分植物和杂草。

并以狙击手般的精确度部署

这些
浓缩肥料

或除草剂的微小射流

,焚烧幼草。

我了解到机器人技术
如何结束在数百万英亩土地

上广播喷洒化学品的做法,

以及我们如何
将除草剂的使用量

减少多达 90%。

但更大的
图景更令人兴奋。

智能机器
可以单独处理植物,

不仅可以逐株使用除草剂,

还可以逐株使用杀真菌剂、杀虫剂

和肥料,
而不是逐块施肥。

因此,最终,

这种超特异性农业

可以实现更多的多样性
和田间间作。

大农场可以
开始模仿自然系统

并改善土壤健康。

Heraud
是第三方思维的体现,对吧?

他告诉我,机器人

不必将我们从自然中移除,

它们可以让我们更接近自然,
它们可以恢复自然。

增加作物多样性

对于建立有复原力的粮食系统至关重要。

分散农业

也是如此,这样当
一个地区的农民受到干扰时,

周围的其他地区的农民就可以继续增长。

垂直农场的兴起,

比如这个农场,建在
新泽西州纽瓦克的一家前钢铁厂内,

可以在分散农业方面发挥关键作用

Aeroponic 农场

使用的水仅占
地下农场用水的一小部分。

他们可以更快地种植食物,
大约快 40%。

当位于食物消费的城市及其附近时

它们消除了大量
的卡车运输和食物浪费。

起初让我感到毛骨悚然

的是一种“无声运行”的方式

,我们将在里面种植
我们未来的水果和蔬菜

,没有土壤或阳光。

在这些植物工厂呆了数周后,

我开始觉得很奇怪,
几乎完全自然

地只提供植物
,完全符合他们的需要

,零除草剂
和激进的效率。

在这里,我们再次看到创新者
借鉴

甚至提升
了自然生态系统的智慧。

植物性
肉类和替代肉类

的发展也充满希望。

他们遵循类似的

本地、弹性、
低碳蛋白质生产趋势。

消费者对此感到兴奋

,在大流行期间,

我们看到

对替代肉类的需求增加了 250%。


临床营养学杂志》的一项研究

发现,
食用植物性蛋白质的参与者

的胆固醇水平

、体重

下降,最终
患心脏病的风险下降。

植物性肉类的潜在环境效益令人震惊。

甚至
在实验室培养或基于细胞的肉类中也有潜力。

乌玛·瓦莱蒂(Uma Valeti)给我吃了第一
盘实验室培育的鸭胸肉,是

从生物反应器中新鲜收获的。

它是
从从肌肉组织、脂肪和结缔组织中提取的一小部分细胞样本中生长出来的

这正是
我们吃肉时所吃的东西。

这种实验室培育的或以细胞为基础的

鸭肉几乎没有受到
细菌污染的威胁,

与之相关的二氧化碳排放量降低了约 85%

最终,它可以

像那些在分散设施中的垂直农场内种植的作物一样种植,这些作物

不易
受到供应链中断的影响。

瓦莱蒂最初是一名心脏病专家,

他知道几十年来医生
一直在实验室开发

人体和动物组织

他的灵感与

1931 年
温斯顿·丘吉尔 (Winston Churchill) 的一句话一样受到启发,他说:

“通过在合适的培养基中分别种植它们,我们将摆脱为了吃
鸡胸或鸡翅而种植整只鸡的荒谬

。”

和 Heraud 一样,Valeti
是典型的第三向思想家。


使用新技术

重新构想了一个旧想法,以推出一个
时机成熟的解决方案。

我在世界各地会见了数十名模仿第三向思维的农民
、企业家和工程师

他们正在使用
CRISPR 等现代育种工具

来开发
能够抵御干旱和高温的营养丰富的传家宝作物。

他们正在使用人工智能使
水产养殖可持续发展。

他们正在寻找
消除食物浪费的方法。

他们正在扩大

保护性农业
和管理放牧。

他们正在恢复古老的植物

,他们正在回收
污水和灰水

以开发抗旱供水。

结果是这样的:

将新旧食物生产方法结合起来的人类创新

可以,而且我相信,将
引领第三种方式,

并大规模重新定义可持续
食品。
