6 Minute English from the BBC.
2
Hello, this is 6 Minute English from BBC Learning English.
3
I'm Neil.
4
And I'm Sam.
5
We're talking about the environment in this programme, specifically climate change.
6
Now Sam, what do you think is the biggest cause of climate change?
7
An obvious answer would be that climate change is the result of carbon emissions caused by humans.
8
It's about people's carbon footprint – the measurement of how much carbon dioxide is produced by someone's everyday activities.
9
That makes sense.
10
But recently some scientists, especially in the West, have been focusing on another issue – the increasing number of people in the world, something known as overpopulation.
11
In this programme, we'll be discussing the controversial link between overpopulation and climate change.
12
And as usual, we'll be learning some new vocabulary as well.
13
as well.
14
Sounds good, Neil.
15
But first I have a question for you.
16
Over the last 100 years, within one lifetime, the world's population has soared.
17
At the start of the 20th century, it was around one and a half billion.
18
But how many people are there in the world today?
19
Is it a 7 billion, b 8 billion or c 9 billion?
20
I'll say around 8 billion people live on the planet today.
21
I'll reveal the answer later in the program.
22
Since climate change is caused by human activities, it seems common sense that fewer people would mean lower carbon emissions.
23
But in fact, the connection isn't so simple.
24
Not everyone emits carbon equally, and people in the Western world produce far more than people in sub-Saharan Africa or Asia.
25
Arvind Ravikumar is Professor of Climate Policy at the University of Texas.
26
He's made the surprising calculation that an extra two billion people born in low-consuming countries would actually add very little to global carbon emissions.
27
Here, Kate Lamble and Neil Rozelle, presenters of BBC World Service programme The Climate Question, discuss Professor Ravikumar's findings.
28
What he's saying is kind of astonishing, right?
29
Two billion people is, to say the least, a lot.
30
It's the combined population of Europe and Africa.
31
He's crunched the numbers and found that an extra two billion low-income people, as defined by the World Bank – these are people without cars, without electricity often – would see global emissions rise by just 1.5%.
32
Add 2 billion high-income earners – that's people with cars and power and all the mod cons – and Arvid reckons emissions would rise by more than 60%.
33
So when it comes to climate change and population, where you were born matters.
34
Professor Ravi Kumar made his discovery after crunching the numbers – an idiom meaning performing many mathematical calculations involving large amounts of data.
35
He concluded that whereas 2 billion low-income people would increase carbon levels very little, 2 billion high-income people would increase it a lot.
36
That's because high-income populations have mod cons, which is short for modern conveniences, technology and machines like cars, fridges and air conditioning that make life easier and more pleasant.
37
According to this view, the real problem is not overpopulation, but overconsumption.
38
Affluence – that's having lots of money and owning many things – has become a big factor in climate change.
39
And that's true in poorer countries as well as richer ones.
40
Listen to Rajesh Joshi, reporter for BBC World Service's The Climate Question, interviewing a rich Indian housewife, Priti Dagan, in her luxurious home in New Delhi.
41
I need everything that I buy.
42
You cannot be judgemental about anybody's needs.
43
And I derive a lot of happiness out of being very, very drawn towards consumer things.
44
and I love it and I'm not apologetic about it.
45
So if I tell you that poor people have a smaller carbon footprint as compared to their richer counterparts, do you feel apologetic about it?
46
So the brain says yes, we should be apologetic about it, but the heart does not agree.
47
Yes, poor can't afford lots of stuff so their carbon imprint is small, but here my heart wins over my brain because it gives me happiness.
48
Priti does not feel apologetic about her shopping.
49
She doesn't think that she should feel sorry.
50
Shopping makes her happy and she lets her heart rule her head – an idiom meaning that you do something based on emotions rather than reason.
51
Priti is being very honest.
52
She is consuming and looking for happiness in a way that people in the West have been doing for decades.
53
It seems overconsumption is a bigger cause of climate change than raw population numbers.
54
Speaking of which, what was the answer to your question, Sam?
55
Ah yes, I asked about the current global population.
56
You guessed it was around 8 billion people, which was the correct answer.
57
According to the United Nations, the world's population reached 8 billion on November 15, 2022.
58
Right, let's recap the vocabulary we've learned, starting with carbon footprint, a measurement of how much carbon dioxide someone's activities produce.
59
If you crunch numbers, you perform many mathematical calculations involving large amounts of data.
60
Modcons is short for modern conveniences, conveniences – machines like cars, washing machines and fridges, which make life easier and more pleasant.
61
Affluence means having lots of money or material possessions.
62
If you are apologetic, you show that you feel sorry for something harmful you have said or done.
63
And finally, the idiom let your heart rule your head means to do something based on emotion and personal desires, rather than for logical or practical reasons.
64
For now, it's goodbye.
65
Bye-bye.

背景与语境
在这段来自BBC的《6分钟英语》节目中，主持人Neil和Sam讨论了气候变化及其与人口增长之间的关系。节目中提到，由于人类活动导致的碳排放是气候变化的主要原因，而近期科学家们开始关注另一个问题——人口过多。在这个讨论中，科学家们探讨了高收入和低收入国家的人口对碳排放的影响，强调了消费水平而非单纯人口数量的重要性。
日常交流的五个重要短语
- carbon emissions - 碳排放
- carbon footprint - 碳足迹
- overpopulation - 过度人口
- high-income earners - 高收入者
- mod cons - 现代便利设施
逐步跟读指导
为了提高你的英语口语能力并更好地理解这段对话，可以按照以下步骤进行shadow speak练习：
- 收听和理解: 首先，观看这段YouTube视频并认真倾听每位主持人的发言。试着理解他们表达的每一个观点。

- 应用新词汇: 在日常交流中尝试使用在节目中学习到的短语，例如“碳排放”和“过度人口”，这样能帮助你加深记忆并提高口语能力。
- 互动与实践: 寻找伙伴一起练习，让他们提供反馈，或者参加英语口语俱乐部，与其他英语学习者交流，分享你从视频中学到的知识。

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
