Global warming and the dumb problem of food waste

[Music]

well let’s start let’s start at the

beginning so so what is drawdown can you

just break that down for us so so

drawdown

is a point in time it’s that time

when we uh uh reduce atmospheric

concentrations

on a year-to-year basis when we

essentially when we pull out more

greenhouse gases

that we’re putting in to earth’s

atmosphere

and the proposition is really simple

when we can

reduce those concentrations of heat

trapping gases

we can essentially affect global cooling

essentially stopping global warming and

beginning

a long process of reversing it and so

that’s what drawdown is

that point in time when we can start to

really

uh reduce atmospheric greenhouse gases

well that’s interesting because we often

talk about

mitigating climate change

and you guys at drawdown are taking

quite a strong position here you’re

saying

we can reverse global warming

absolutely i mean mitigation just means

to lessen

it means to reduce the impact of and

that’s important we need to

mitigate uh the impact of climate change

and

probably more important we need to

mitigate or reduce

to less than reduce the emissions that

are going into the atmosphere to start

with

um but mitigation is only part of it and

it’s an important

step being stoned to a goal that we

actually want

what we really want to do is stop global

warming and begin to reverse it

that’s what that’s the aim that’s sort

of what i like to think of as like

the marker on the horizon

pointing us to the future that we

actually want right

there’s many pathways to get there right

and mitigation is one

one strategy it’s getting us partially

there

but if we don’t envision where we

actually want to be we’re not going to

get there

so we need to say what is it that we

want we want to stop

global warming we want to begin the

process of reversing it

we need to find and take the first steps

on that pathway

to reach that horizon point and move as

fast as we can as urgently

as safely and as equitably as we can to

get there

um but if we don’t name that as a

starting point we’re never ever going to

reach there so that that’s really what

we want to set out

with with drawdown with project drawdown

is to name

the goal name where we actually want to

be and not confuse things

not name half measures like mitigation

to a to to ensure a two degree warming

target

celsius warming target or a 1.5 degree

celsius warping target these are very

important targets

very important but again these are stop

gap measures

we want to go beyond that we want to say

okay yes let’s go there

but let’s go further yeah where do we

how do we go further than that and

create a

regenerative society and regenerative

economy

that benefits all people while at the

same time

solving the climate emergency that we’re

all facing today well and we often use

uh climate change and global warming

interchangeably

but you make a very specific distinction

between the two

can you tell us about that absolutely

and

and it’s okay first of all to use them

interchangeably because we have done

that

so often uh uh as we as we discuss and

in this discourse we’ve certainly been

using them interchangeably and to a

certain extent we can’t

um but i think that there is an

important distinction when we really

have to think about the solutions

to the problem at hand right um

climate change is essentially a symptom

a symptom of a deeper problem it’s the

earth it’s telling us what’s going wrong

uh it’s the in what’s going wrong is

actually

global warming that’s what’s causing

climate change

uh and it’s it’s affecting uh the

atmosphere it’s affecting our

uh our climate um and so we need to

address

not just the symptoms the climate change

itself but we need to

address the actual cause of the sickness

the cause

of the disease and that is emissions

themselves

emissions caused by human activity that

are entering the atmosphere

trapping heat and essentially uh it’s

like putting we’re basically putting

lots of blankets over the planet

it is experiencing a fever right it’s

getting hotter and hotter and hotter

and this is causing all of these uh

other impacts to our terrestrial systems

to our ocean systems to our biodiversity

and to human social and economic systems

and it’s and it says these are the

symptoms of that problem so

how do we actually address the problem

itself

how do we how do we address the cause of

these symptoms

and that is how do we turn off the

emissions

that are for the for as a starting point

causing the global warming

and how do we enhance those sinks those

natural uh natural carbon sinks in our

in our land

and our ocean systems that pull carbon

dioxide out of the atmosphere

and that’s a way for us to help uh

solve and help cure the illness that we

already are experiencing so how do we

turn off the emissions

turn up the uh the sinks and and really

address

the root cause of the illness itself

but we have to do that in a equitable

and safe and inclusive way with justice

at its core

because these are technologies and

practice that we profile draw down that

have a direct

effect on emissions but there’s deeper

embedded systems and structures in place

that also have to be addressed to shift

the system

from exploitation and extraction which

are in no small measure

causing and rooted in creating these

emissions uh to a restorative and

regenerative system

as i said which can address the

underlying structures themselves

and that has to be done with with with

justice and

uh inequity and inclusion at its heart

and that’s how we have how we need to be

implementing these solutions and solving

the problem itself

well and your research has led you to

100

solutions or at least priority areas

the shocking thing for me personally was

to find

food waste and food laws right at the

top of that list

as a potential solution to to impacting

emissions

you want to expand on that yes of course

so

so what we did over the course of the

last six years

uh is assemble a team of researchers

from all over the world

and we’ve mapped measured and described

real

existing technologies and practices

that when taken together as a system of

solutions

can achieve this goal of drawdown

can can help us achieve our global goals

the sustainable development goals

can help us go on this pathway towards

that future that we want

and so we’ve mapped a lot of these

solutions some of these are existing

some of the hundred that we profiled in

our first book uh

drawdown in 2017 some of them are coming

attractions these are

new emerging technologies that can come

on board and when they come on board

into the system they can

help accelerate our progress um but most

of them

uh at the time 80 solutions uh

that we published a book um uh are are

existing technologies that can uh

achieve drawdown we’ve recently in in

2020 produced the drawdown

review which is an update of all of our

research from the book in 2017

and so some of the solutions have

shifted they’ve changed in terms of

their rankings

and we have 76 solutions now in the

drawdown review

and these are really really global

solutions that are applicable in a

variety of spaces and one of the ones

that

really reach the top again so in in 2017

reducing food waste was our number three

solution

in the latest review uh it’s still

in the the top uh top three solutions we

produced two new scenarios one scenario

scenario one

is aligned with a two degree warming

target two degree warming celsius target

and the other scenario is aligned with a

1.5 degree

celsius warming target in each of these

two scenarios

uh food waste really tops the list and

in the two-degree warming target it’s a

it’s the

it’s the top the first the number one um

and then the 1.5 is

it’s again the third third solution so

but the point is these are really really

important it’s a really important uh

solution um and

uh and it’s it’s it’s kind of

if we think about uh food loss

and waste um it becomes pretty obvious

right

uh currently we we we lose or waste

about 30

or 30 to 40 percent of all food that’s

produced for human consumption

it’s not even consumed and that that

loss

in waste accounts for about eight

percent of our global greenhouse gases

and it’s kind of i have to be honest

daddy it’s one of the dumbest things

we ever can do as a species i mean

humanity is brilliant let’s get

we are a brilliant species but we do

some incredibly dumb things at times

like creating a system that’s

exploitative and extracted to start with

so the whole system can be done at times

but there’s some brilliant things that

have come out of that

don’t get us wrong um but one of the

really dumb things we could do is

um produce so much food and waste 30 to

40 percent of it

so so i think how we we need to really

when we see that

as sort of uh an opportunity to change

and to find what are the solutions to

those food loss and waste

and try to prevent that eight percent

global greenhouse gases

it becomes really clear that it’s it’s

one of the most important uh in

solutions

yeah did you say eight percent is that

about eight percent

global greenhouse gases yeah yeah okay

that is not a small amount

yeah yeah well

sorry yeah that that’s interesting

because

um you know the dominant narrative here

has been

has been that if we you know if when we

change and

well we should uh from fossil fuels to

to to to solar energy for example um

that’s the big change that the world

needs to make and you’re suggesting

something

something else here yes in addition to

that and maybe even more importantly

than that

we need to be looking at our food system

as as the big shift that the world needs

to make

in in how we live how we produce

and and and what impact will have on

emissions

yeah i i i would caution to say level of

importance

because we need them all and in fact how

we address electricity generation

is one of the most important solutions

and we need to achieve a 100

clean renewable grid as as as

urgently and as safely as possible um

and because this is the electricity

generation counts about 25

of global greenhouse gases as a whole

right but where are the other 75

coming from um and they come 24

of global greenhouse gas gases comes

from uh uh the food system itself

um about the but what we’re consuming

how we’re producing that food and what

we’re

wasting um uh and and and that 24

meat can be addressed and of course

there are other sectors as well

buildings and transportation and our

industrial processes that accounts for

the other 50

of global greenhouse gases so we need

them all it’s not a level of

what’s more or less important there are

no silver bullets

there’s no subset of these solutions

that are going to get us there

um there’s not the top 20 or top 30 or

top 40

we need all of the solutions to address

all of these areas of human

activity um but what is surprising and i

think what what you’re what you’re

addressing here

tati is that um we don’t typically think

about the food system

in uh in in the discussion around

sustainability

and the discussion around addressing uh

climate action though things have

started to change a lot in the last five

years that makes us

natural climate solutions and our food

systems are becoming more and more

prevalent in the discourse but it’s

still

not something that’s really understood

or known i mean it’s surprising to

people

all over the place and um but if you

stop and think about it for just

a minute it becomes pretty clear why

it’s such an important contributor to

greenhouse gases

uh because think about the food chain

itself

yes if we think about sorry

i was saying yes oh yes if we think

about if anything like the food chain

itself which is

how food gets to our mouths right

from production to harvesting and

processing

packaging distribution markets

consumption

and then the end of life of food we

think about that entire chain

but every crust of bread every drop of

oil that we’re producing to consume

goes through all of that and

there are there’s energy there’s labor

there’s money of course and there’s

emissions

that go along with each of those points

along the food chain

so um whether we’re producing food

and where it sadly and one of the number

one drivers of deforestation

uh and land conversion is agriculture so

producing

food for consumption contributes

emissions and then how we’re producing

it using

increasingly using industrial modern

agriculture which promotes

monocropping do you said it’s that

synthetic fertilizers and pesticides um

and and uh and tillage which uh

ultimately

turn land into a net emitter and

degrades the emitter of

of greenhouse gases and degrades the

land right

uh their emissions that happen there but

if you think that production and go

outward to processing

making that food into various other uh

food sets that we’re familiar with those

commodities into other foods that we’re

familiar with

to packaging think about all the tin the

plastic

the glass being made in factories

and they’re churning out emissions to

produce this

material that we then put food into

and then we take that food and we put it

on trucks

trains ships and

sadly with too many luxury items

on planes to travel all over the world

and even in our own in our own

communities in

our own our own regions traveling all

over the place all of that

is using as it producing emissions

combusting fossil fuels to move that

stuff around the world

yeah and i think that’s a pretty good

way to to close this discussion and

thank you so much for

the work that you do it’s it’s much

needed it it certainly clarifies

the problem but it offers the solutions

as well but my last question to you

is on a scale of one to let’s say a

hundred

uh how optimistic are you that we can

reach draw down

daddy that’s a challenging question one

to a hundred goodness well first of all

is a hundred the most optimistic 100

most optimistic i am

i would say let me think about this um

i would say i’m a solid i’m a solid 85

yeah i’m a solid 85. and and and it

depends on the optimist to achieve what

is it the two degree warming celsius

warming target 1.5

degrees celsius swimming target is it

our sustainable development goals

is it that marker on the horizon

um these are different things and

they’re different stepping stones

and i think um i’m 85 because i believe

deeply

in the brilliance of humanity i believe

in the

beautiful beauty of humanity and no

small measure it was my experience

for two months backpacking in

sub-saharan africa

that kindled this sense of

how real people

people can be so beautiful and real and

really connected to

nature and the earth and the planet and

that kindle us hope and that i could

sign everyday people

everybody i encountered that that these

kind

of solving this is possible because

because humanity is brilliant and you

see that in local communities you see

that in indigenous peoples communities

you see that

um in in the sub-saharan context in

those places that i i cherish

and and that killed me handled in me the

hope

that we can actually achieve and that’s

why if i didn’t have that i wouldn’t be

spending

the last 12 years doing everything in my

power and even my ability

to uh get us on this pathway to a

regenerative system

uh in social media small measure and i’m

so happy to be

able to speak to folks here today on

from the continent

um and uh uh i thank you for the

opportunity

i’m i’m i’m i’m more optimistic now than

ever

uh in the past and and i appreciate this

uh this chance to

chat with you all and thank you for the

world chad thank you very much

[音乐]

好吧,让我们从头

开始,所以什么是缩编,您可以

为我们分解一下吗,所以

缩编

是一个时间点,是

我们呃呃逐年减少大气

浓度的时间点 当我们从

本质上抽出更多

排放

到地球

大气中的温室气体时

,这个提议非常简单,

当我们可以

减少那些吸热气体的浓度时,

我们可以从本质上影响全球降温,从

本质上阻止全球变暖并

开始

一个漫长的过程 扭转它,所以

这就是

我们可以开始

真正减少大气温室气体

的那个时间点,这很有趣,因为我们经常

谈论

缓解气候变化,

而你们在缩编时在这里占据了

相当大的位置

我们可以绝对扭转全球变暖

我的意思是缓解只是

意味着减少

它意味着减少影响,

这很重要 我们需要

减轻气候变化的影响,

可能更重要的是,我们需要

减轻或减少

到少于减少

进入大气

排放量,但减轻只是其中的一部分,

这是重要的

一步 坚持一个我们真正想要的目标

我们真正想做的是阻止全球

变暖并开始扭转它

就是我喜欢认为的目标 就像

地平线上的标记

指向我们的未来 我们

实际上想要正确,

有很多途径可以正确到达那里

,缓解是

一种策略,它让我们部分到达

那里,

但如果我们不设想我们

真正想要的地方,我们就不会

到达那里,

所以我们需要说出什么是 我们

想要我们想要阻止

全球变暖 我们想要开始

扭转它的过程

我们需要找到并

在这条道路

上迈出第一步,以达到那个地平线点,并

尽可能快地

采取行动 安全和公平地

到达那里,

嗯,但是如果我们不将其命名为

起点,我们将永远无法

到达那里,所以这就是我们想要

通过项目提款的提款

开始的

说出我们真正想要成为的目标名称

,不要混淆事物,不要说出

半措施,例如缓解

到 a 以确保 2

摄氏度的升温目标 摄氏升温目标或 1.5

摄氏度的翘曲目标 这些是非常

重要的目标,

非常重要,但同样这些 是权宜之计

我们想要超越 我们想说

好的 是的 让我们去

那里 但让我们

走得更远 是时候

很好地解决我们今天都面临的气候紧急情况了,我们经常交替使用

呃气候变化和全球变暖,

但你可以在两者之间做出非常具体的区分

你绝对告诉我们这一点

首先可以互换使用它们是

可以的,因为我们经常这样做

呃,在我们讨论的时候,

在这个演讲中,我们当然一直在

互换使用它们,在

某种程度上我们可以 '

不是,但我认为

当我们真的

必须考虑

手头问题的解决方案时,有一个重要的区别,嗯,

气候变化本质上

是一个更深层次问题的症状,它是

地球,它告诉我们出了什么问题,

呃 问题出在哪里,

实际上是

全球变暖,这就是导致

气候变化

的原因 疾病的实际原因 疾病

的原因

,即排放物

本身

由进入大气的人类活动引起的排放物

捕获热量和 es

基本上,这就像我们

在地球上盖了很多毯子一样,

它正在发烧,它

变得越来越热,越来越热

,这

对我们的陆地系统

、海洋系统和生物多样性造成了所有这些呃其他影响

对人类社会和经济

系统而言,它说这些

是该问题的症状,那么

我们如何实际解决问题

本身

我们如何解决这些症状的原因

,这就是我们如何关闭

排放

那是为了作为

导致全球变暖的起点

,我们如何增强这些汇

在我们的土地

和海洋系统中的那些天然碳汇,这些天然碳汇将

二氧化碳从大气中抽出

,这是我们的一种方式 帮助呃

解决并帮助治愈我们

已经在经历的疾病那么我们如何

关闭排放

打开呃水槽并真正

解决

疾病的根本原因 ess 本身,

但我们必须以公平

、安全和包容的方式做到这一点,以正义

为核心,

因为这些技术和

实践是我们描述的

对排放有直接影响的技术和实践,但有更深层次的

嵌入式系统和结构

到位 必须解决该问题,以

将系统

在很大程度上

导致并根植于产生这些

排放的开发和提取转变为恢复性和

再生系统,

正如我所说的那样,它可以解决

底层结构本身

并且必须与 以

正义、

呃不公平和包容为核心

,这就是我们需要如何

实施这些解决方案并很好地

解决问题本身的方式

,您的研究已使您找到了

100 个

解决方案或至少是优先

领域,这对我个人而言令人震惊的是

在该列表的顶部找到食物浪费和食物法

作为影响排放的潜在解决方案

想扩展这一点,是的,当然

所以我们在

过去六年中

所做的就是组建一支来自世界各地的研究人员团队

,我们绘制了测量和描述的

真实

现有技术和实践的地图

,当它们结合在一起时 作为一个

解决方案系统

可以实现这一目标 缩编

可以帮助我们实现我们的全球

目标 可持续发展目标

可以帮助我们沿着这条通往

我们想要的未来的道路前进

所以我们已经绘制了很多这样的

解决方案 其中一些

我们在 2017 年的第一本书 uh drawdown 中介绍了数百个中的

一些,其中一些是即将到来的

吸引力这些是

可以加入的新兴技术

,当它们

加入系统时,它们可以

帮助加速我们的进步,嗯,但是

他们中的大多数

当时我们出版了一本书的80个解决方案呃是

现有的技术,可以呃

实现缩编我们最近在

2020年制作了drawdo wn

评论,这是我们

2017 年书中所有研究的更新

,因此一些解决方案

已经发生了变化,它们的排名发生了变化

,我们现在有 76 个解决方案在

缩编审查中

,这些真的是真正的全球

解决方案 适用于

各种空间,其中一个

真正再次达到顶峰,因此在 2017 年

减少食物浪费是我们

在最新评论

中的第三大解决方案

情景一种情景

情景

一与升温

2 摄氏度的目标一致 升温 2 摄氏度的目标

,另一种情形与

两种情况的

升温 1.5

摄氏度目标一致 升温目标这是一个

它是

它的顶部第一个第一嗯

然后1.5

又是第三个第三个解决方案所以

但重点是这些真的很

重要我 这是一个非常重要的

解决方案,嗯,

嗯,

如果我们考虑一下,食物损失

和浪费,那就很明显了,

嗯,目前我们损失或浪费了

大约 30

% 或 30% 到 40% 的所有食物

对于人类消费

来说,它甚至没有被消耗掉,

浪费的损失约占

我们全球温室气体的 8%,

老实说,

这是我们作为一个物种所能做的最愚蠢的事情之一,

我的意思是

人类是 聪明,让

我们成为一个聪明的物种,但我们有时会做

一些非常愚蠢的事情,

比如创建一个具有

剥削性和提取性的系统,

以便有时可以完成整个系统,

但也有一些很棒的事情由此产生

。 不会误会我们的意思,但是

我们可以做的真正愚蠢的事情之一就是

生产这么多食物并浪费其中的 30

% 到 40%,

所以我认为

当我们看到

这有点像一个操作时,我们真的需要怎么做 有机会改变

并找到解决

这些粮食损失和浪费的方法,

并努力防止 8% 的

全球温室气体排放,

这变得非常清楚,它是解决

方案中最重要的一种,

是的,你说 8% 是

关于 8% 的

全球温室气体 是的 是的 好吧

这不是一个小数目

例如,燃料

到太阳能到太阳能,嗯

,这是世界需要做出的重大改变

,你在这里提出

一些别的建议,是的,除此之外

,也许更重要

的是,

我们需要关注我们的食物系统

正如世界需要

在我们的生活方式以及我们的生产方式

以及对

排放产生什么影响方面做出的重大转变

重要性,

因为我们都需要它们,事实上,

我们如何解决发电问题

是最重要的解决方案之一

,我们需要尽可能紧急和安全地实现 100 个

清洁的可再生电网

,因为这是

发电量 25

种全球温室气体作为一个整体是

正确的,但其他 75 种来自哪里?

它们来自 24

种全球温室气体气体

来自呃呃食物系统本身,

嗯,但是我们正在消耗什么,

我们是如何生产的? 食物和

我们正在

浪费的东西,嗯,还有 24 种

肉类可以解决,当然

还有其他部门以及

建筑和交通以及我们的

工业过程,它们占

全球温室气体的另外 50 种,所以我们需要

它们全部 不是一个

或多或少重要的水平

没有灵丹妙药

没有这些解决方案的子集

可以让我们到达那里

嗯没有前20名或前30名或

前4名 0

我们需要所有解决方案来解决

人类活动的所有这些领域

嗯,但令人惊讶的是,我

认为你是什么,你在

这里要解决的问题

是,嗯,我们通常不会

考虑食物

系统 呃在关于

可持续性的讨论和关于解决呃气候行动的讨论中,

尽管

在过去五年中事情已经开始发生很大变化

,这使得我们

自然气候解决方案和我们的粮食

系统在讨论中变得越来越

普遍,但它

仍然

不是真正理解或知道的东西,

我的意思是,这让

全世界的人都感到惊讶,嗯,但是如果你

停下来

想一想,就会很清楚为什么

它是温室气体的重要贡献者,

嗯,因为想想食物 链

本身

是的,如果我们考虑一下对不起,

我说是的

从生产到收获和

加工

包装 分销市场

消费

,然后是食品生命周期的终结 我们

会考虑整个链条,

但是每一块面包皮

我们生产的每一滴油

都经过了所有这些过程,并且

有能量 有劳动力

,当然有钱,还有

排放

,伴随着食物链上的每一个点

所以无论我们是在生产食物

,还是在哪里生产食物,可悲的是

,砍伐

森林和土地转换的首要驱动因素之一是农业,所以

生产

消费食品会导致

排放量,然后我们如何

使用

越来越多地使用

促进

单作的工业化现代农业来生产它,你说的是

合成肥料和杀虫剂,嗯

,嗯,还有耕作,

最终

将土地变成净排放物并

降低排放物

的温室气体和退化的

土地权利

呃他们的排放发生在那里但是

如果您认为生产并

向外加工,

将这些食物制成

我们熟悉的各种其他呃食品套装,将这些

商品制成我们

熟悉

的其他食品包装考虑所有的锡,

塑料,玻璃制成 工厂

,他们大量排放来

生产这种

材料,然后我们把食物放进去

,然后我们把食物

放在卡车上,

火车上,轮船上,

遗憾的是,飞机上有太多的奢侈品

,无法环游世界

,甚至在 我们自己在我们自己的

社区在

我们自己的地区

到处旅行所有这些都在

使用,因为它产生排放

燃烧化石燃料将这些

东西运送到世界各地

是的,我认为这是结束这个讨论的一个很好的

方式

非常感谢

你所做的工作,这是非常

需要的,它确实澄清

了问题,但它也提供了解决

方案,但我对你的最后一个问题

是规模为 1 让我们说

一百

呃你有多乐观我们可以

达到画下来

爸爸这是一个具有挑战性的问题一

到一百善良首先

是一百最乐观的一百

最乐观

我会说让我想想这个嗯

我会说我是一个坚实的我是一个坚实的 85

是的我是一个坚实的 85。而且这

取决于乐观主义者来实现

它是什么 升温 2 摄氏度

升温目标 1.5

摄氏度 游泳目标是

我们的吗 可持续发展目标

是地平线上的标志

嗯,这些是不同的东西,

它们是不同的垫脚石

,我想嗯,我已经 85 岁了,因为我深信

人类的光辉,我相信人类

美丽,不

小 衡量一下,我

在撒哈拉以南非洲背包旅行两个月的经历

激发了这种感觉,

即真实的

人是如何如此美丽和真实,并

真正与

自然、地球和地球以及

那种点燃的 我们希望并且我可以

签署每天

我遇到的每个人,

这种解决方法是可能的,因为

因为人类是聪明的,你

看到在当地社区你

看到在土著人民社区

你看到

嗯在撒哈拉以南 在

那些

我珍视并杀死我的地方的背景下,我怀揣

着我们能够真正实现的希望,这就是

为什么如果我没有这种希望,我将不会

在过去的 12 年中尽我

所能,甚至是我的 有能力

让我们走上通往再生系统的这条道路

嗯,在社交媒体上,我

很高兴

今天能够与来自非洲大陆的人们交谈,

嗯,嗯,谢谢你给我这个

机会

我是我我现在比

以往任何时候都更乐观

,我很感激有

这个机会

和大家聊天,谢谢你的

世界乍得非常感谢
