Hey, it's Hannah here. Welcome back to What in the World, your favorite podcast for all your news, trends and talking points from the BBC World Service. So I got a question for you.
2
Which do you think is bigger Africa or North America?
3
If you use the map that most of us were taught about in school, you'd probably get it wrong.
4
And that's because the Mercator projection, which has been around for about 450 years, distorts size.
5
It makes Europe and Greenland look loads bigger while shrinking Africa and South America. And now campaigners are asking for a new map to be used instead, the Equal Earth map.
6
And you can see how much bigger Africa looks in comparison.
7
And they've got the support of the African Union, which represents all 55 states on the continent.
8
So today we're asking, could a new world map change how we see the world?
9
Let's hear more about this now from BBC Africa reporter Makuochi Okafor.
10
Hey Makuochi. Hi, Hannah.
11
So this really taps into some big sentiments and big feelings at the moment. A push for equality.
12
Equal representation. Equality on a world stage.
13
And there's this big campaign called correct the map.
14
And and it's been backed by the African Union.
15
So that's pretty big isn't it. Mhm. You're right.
16
Um so this campaign, the Correct The Map campaign, this is not the first time um they started it. It's been happening for quite a bit.
17
I do know that there are two organizations, two advocacy groups that have been very loud and have been more like at the forefront of this campaign.
18
And that is the Africa No Filter and the Speak Up Africa group.
19
Uh, both are advocacy groups, both are advocacy groups who have sort of always fought for everything Africa, you know.
20
So now that they've sort of pushed enough for the Africa Union, which represents all 55 states, uh, countries in Africa, to sort of hear their voice and adopt this, Correct The Map, um, you know, campaign or the map itself.
21
It actually seems like they have made a mark.
22
In fact, I remember, um, the founder and lead of the Africa No Filter, spoke with a BBC team recently, and she said she felt like the world has heard them, but, um, she doesn't want that to be where it will stop.
23
They want schools, global organisations and even countries to start and government to start adopting the use of the equal earth beyond just, um, the African Union saying that they would like for it to be adopted.
24
Yeah. We actually heard, um, from Moky Makura, the executive director of Africa No Filter about why this campaign is so important to her.
25
I think the most important part of this is that we're actually showing something that is incorrect.
26
I've referred to this as the world's longest misinformation campaign because it's just wrong.
27
And I think the one example people use is the size of Greenland, which is depicted on current projections as 14 times larger than it actually is.
28
The point is that Africa is made to look smaller than it really is.
29
Um, the distortion matters because it literally shrinks Africa's power and our place in the world.
30
You know, the size being smaller than European countries, when in reality you can fit all of Europe, China, India, America and other countries into the continent.
31
It makes the continent look less important, less powerful, and less full of potential.
32
I'd like to see the Equal Earth projection used everywhere.
33
So in school textbooks, online, on Google Maps, in PowerPoint templates, in Canva templates, you know, the Mercator projection has been the default for 450 years.
34
And we need Equal Earth to become just as ubiquitous.
35
Everywhere I turn, I should see Africa depicted in the right way.
36
And that way everyone, everywhere sees the world to the real scale.
37
I want to get into the geography here.
38
So the map that we've mentioned that we've been talking about, the Mercator projection, it was designed in 1569, but it was originally designed for sea navigation.
39
So why does it depict Africa and South America smaller than they actually are?
40
We got in touch with YouTuber Geodiode, who's also known as Edwin Rijkaart, to get a better idea.
41
The Mercator projection is probably the best known world map.
42
It was created in the 16th century by Gerardus Mercator.
43
His real name was Geert de Kremer.
44
Mercator was just his Latin name.
45
He was Flemish cartographer and one of the pioneers in modern mapmaking.
46
And his idea was to make a map where compass courses show up as straight lines on the map.
47
That was a huge advantage for sailors in the 16th century because it made navigation much easier for them.
48
On Mercator maps, one could easily navigate with a compass.
49
Back in the days, all the lines on the map pointed north, east, south or west, and all the distances on the lines on the map were the same everywhere.
50
No one ever paid attention to the maps, because only a small group of people, uh, used the maps like sailors, for example. But then came the mobile phone, and we all started using Google Maps or another navigation app.
51
And Google uses the Mercator format because it's easy to navigate.
52
It's impossible to create a perfect map because the Earth is a three dimensional sphere and the map is flat.
53
So when you try to flatten a sphere, something always gets distorted.
54
That's why there are so many different map projections.
55
Each one emphasizes something different and is used for a different purpose.
56
So Makuochi. Criticism of the Mercator map isn't new.
57
I mean, it is impossible to get something that is round in 3D to lie flat, right?
58
You just you can't squish an orange down.
59
But why is this issue being raised again now do you think?
60
Well, the truth is, with the current use and rise of social media and even more like media advancement, it seems like subjects that were sort of little whispers in silos are getting louder and louder, and more people are converging to have these conversations.
61
It just seems like things that are felt in smaller groups are now being collected, and voices are sort of being put together globally.
62
So, um, Africa No Filter and Speak Up Africa and even other organizations sort of have utilized social media and the use of new media and even older traditional media models to push, um, and to push for their, their agenda or what they want.
63
And that has totally worked for them.
64
Yeah. So there are all these small conversations taking place, but the Correct The Map campaign actually has some really big intentions.
65
I mean, they want schools, governments and even major international organizations to change the map that they use.
66
Yes, that's exactly what they are asking for.
67
Um, interestingly, I think they have really done quite well in the sense that this campaign has been a bit successful in the sense that, for example, the AU, by the way, Africa is the second biggest continent.
68
And if the huge governing body is saying they want this, then that's actually a huge thing.
69
But even beyond that, um, organizations like the world Bank say they have stopped using the Mercator projection.
70
They have adopted the Winkel tripel map, which is not entirely the correct, the, uh, the Equal Earth map, but it sort of addresses most of the concerns that people have used when criticizing the Mercator projection.
71
Um, so the world, the World Bank is huge.
72
It's an international organization. Um, and even something like what's it called, National Geographic Society say they also no more use, uh, the Mercator projection.
73
They now use the Winkel tripel map And, you know, Google, which most people use, uh, Google on desktop now uses a 3D model of a map, and they have dropped the Mercator projection.
74
However, users can still switch back to that.
75
And also, um, on on mobile they're still using Mercator projection.
76
But it seems like the more the conversation is happening, global organizations, global societies, and even countries might actually eventually, um, get to adopt, uh, the maybe Equal Earth or other variations of it.
77
What are some of the wider implications of this?
78
What are the wider implications of not using accurate maps or showing Africa as smaller than it really is?
79
Well, I'll give an example. For example, I have heard people say, oh, this tiny country from a specific place.
80
You know, I'm just giving you an example when people say that both the people who live in those countries, or even those who want to either offer aid or even do projects on the country, sort of start thinking of minimizing what they would have offered, or even people who are from those places sort of feel tiny.
81
So you see that it not only affects people's identity and how they feel about themselves, but it actually affects policies that are being made because, you know, visual representation sort of affects perception.
82
So it has this huge boot, um, physical, economic and even psychological impact on the people who are being represented that way.
83
And that has been seen to by most of the campaigners say it has affected most of the policies made towards Africa and even how Africans feel about themselves.
84
Makuochi, thank you so much for explaining that to us.
85
Thank you Hannah. That's it for today.
86
And wherever you are in the world and whatever map you might be using.

練習のヒント
この動画でのリズムやトーンに合わせて、正しい英語の発音をマスターするために、shadowingを試してみてください。特に、話者の言葉を後から追う形式のshadow speechは、発音向上に非常に役立ちます。このアプローチはIELTS スピーキング対策にも応用でき、リスニングスキルも強化できます。
まずは動画を何度も視聴し、言葉のリズムやイントネーションに耳を傾けましょう。その後、実際に声に出してみることで、自然な発音を促進し、英語の発音を良くすることを目指してください。言葉を発する際に、自分が正確に再現できているかを確認し、必要に応じて発音を修正します。このような練習を行うことで、自信を持って話すことができるようになるでしょう。
正しい発音を身につけるためには、shadowspeaksのようなリソースを利用して、自分の声を録音し、その後で聞き返してみると良いでしょう。これにより、自分の成長を客観的に評価し、さらなる改善点を見出すことができます。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
