1
When I was a kid, the disaster we worried about most was a nuclear war.
2
That's why we had a barrel like this down in our basement, filled with cans of food and water.
3
When the nuclear attack came, we were supposed to go downstairs, hunker down, and eat out of that barrel.
4
Today the greatest risk of global catastrophe doesn't look like this.
5
Instead, it looks like this.
6
If anything kills over 10 million people in the next few decades, it's most likely to be a highly infectious virus rather than a war.
7
Not missiles, but microbes.
8
Now, part of the reason for this is that we've invested a huge amount in nuclear deterrents.
9
But we've actually invested very little in a system to stop an epidemic.
10
We're not ready for the next epidemic.
11
Let's look at Ebola.
12
I'm sure all of you read about it in the newspaper, lots of tough challenges.
13
I followed it carefully through the case analysis tools we use to track polio eradication.
14
And as you look at what went on, the problem wasn't that there was a system that didn't work well enough, the problem was that we didn't have a system at all.
15
In fact, there's some pretty obvious key missing pieces.
16
We didn't have a group of epidemiologists ready to go, who would have gone, seen what the disease was, seen how far it had spread.
17
The case reports came in on paper.
18
It was very delayed before they were put online and they were extremely inaccurate.
19
We didn't have a medical team ready to go.
20
We didn't have a way of preparing people.
21
Now, Médecins Sans Frontières did a great job orchestrating volunteers.
22
But even so, we were far slower than we should have been getting the thousands of workers into these countries.
23
And a large epidemic would require us to have hundreds of thousands of workers.
24
There was no one there to look at treatment approaches.
25
No one to look at the diagnostics.
26
No one to figure out what tools should be used.
27
As an example, we could have taken the blood of survivors, processed it, and put that plasma back in people to protect them.
28
But that was never tried.
29
So there was a lot that was missing.
30
And these things are really a global failure.
31
The WHO is funded to monitor epidemics, but not to do these things I talked about.
32
Now, in the movies it's quite different.
33
There's a group of handsome epidemiologists ready to go, they move in, they save the day, but that's just pure Hollywood.
34
The failure to prepare could allow the next epidemic to be dramatically more devastating than Ebola Let's look at the progression of Ebola over this year.
35
About 10,000 people died, and nearly all were in the three West African countries.
36
There's three reasons why it didn't spread more.
37
The first is that there was a lot of heroic work by the health workers.
38
They found the people and they prevented more infections.
39
The second is the nature of the virus.
40
Ebola does not spread through the air.
41
And by the time you're contagious, most people are so sick that they're bedridden.
42
Third, it didn't get into many urban areas.
43
And that was just luck.
44
If it had gotten into a lot more urban areas, the case numbers would have been much larger.
45
So next time, we might not be so lucky.
46
You can have a virus where people feel well enough while they're infectious that they get on a plane or they go to a market.
47
The source of the virus could be a natural epidemic like Ebola, or it could be bioterrorism.
48
So there are things that would literally make things a thousand times worse.
49
In fact, let's look at a model of a virus spread through the air, like the Spanish Flu back in 1918.
50
So here's what would happen: It would spread throughout the world very, very quickly.
51
And you can see over 30 million people died from that epidemic.
52
So this is a serious problem.
53
We should be concerned.
54
But in fact, we can build a really good response system.
55
We have the benefits of all the science and technology that we talk about here.
56
We've got cell phones to get information from the public and get information out to them.
57
We have satellite maps where we can see where people are and where they're moving.
58
We have advances in biology that should dramatically change the turnaround time to look at a pathogen and be able to make drugs and vaccines that fit for that pathogen.
59
So we can have tools, but those tools need to be put into an overall global health system.
60
And we need preparedness.
61
The best lessons, I think, on how to get prepared are again, what we do for war.
62
For soldiers, we have full-time, waiting to go.
63
We have reserves that can scale us up to large numbers.
64
NATO has a mobile unit that can deploy very rapidly.
65
NATO does a lot of war games to check, are people well trained?
66
Do they understand about fuel and logistics and the same radio frequencies?
67
So they are absolutely ready to go.
68
So those are the kinds of things we need to deal with an epidemic.
69
What are the key pieces?
70
First, we need strong health systems in poor countries.
71
That's where mothers can give birth safely, kids can get all their vaccines.
72
But, also where we'll see the outbreak very early on.
73
We need a medical reserve corps: lots of people who've got the training and background who are ready to go, with the expertise.
74
And then we need to pair those medical people with the military.
75
taking advantage of the military's ability to move fast, do logistics and secure areas.
76
We need to do simulations, germ games, not war games, so that we see where the holes are.
77
The last time a germ game was done in the United States was back in 2001, and it didn't go so well.
78
So far the score is germs: 1, people: 0.
79
Finally, we need lots of advanced R&D in areas of vaccines and diagnostics.
80
There are some big breakthroughs, like the Adeno-associated virus, that could work very, very quickly.
81
Now I don't have an exact budget for what this would cost, but I'm quite sure it's very modest compared to the potential harm.
82
The World Bank estimates that if we have a worldwide flu epidemic, global wealth will go down by over three trillion dollars and we'd have millions and millions of deaths.
83
These investments offer significant benefits beyond just being ready for the epidemic.
84
The primary healthcare, the R&D, those things would reduce global health equity and make the world more just as well as more safe.
85
So I think this should absolutely be a priority.
86
There's no need to panic.
87
We don't have to hoard cans of spaghetti or go down into the basement.
88
But we need to get going, because time is not on our side.
89
In fact, if there's one positive thing that can come out of the Ebola epidemic, it's that it can serve as an early warning, a wake-up call, to get ready.
90
If we start now, we can be ready for the next epidemic.
91
Thank you. (Applause)

Por que praticar a fala com este vídeo?

Assistir e praticar a fala com vídeos como o de Bill Gates no TED é uma excelente maneira de aprimorar sua prática de conversação em inglês. Este vídeo aborda um tema relevante e atual, que é a preparação para epidemias e pandemias. Ao imergir-se no conteúdo, você não só aprimora suas habilidades de escuta, mas também tem a oportunidade de praticar a fala. Através da técnica de shadow speech, você pode repetir as falas do speaker, melhorando sua fluência e construção de frases. Essa prática é especialmente benéfica, pois o assunto pode suscitar discussões importantes em conversas informais e formais.

Gramática & Expressões em Contexto

No vídeo, Gates utiliza estruturas gramaticais e expressões que podem ser muito úteis para o aprendizado do inglês. Aqui estão algumas delas:

  • Condicionais: Frases como "If anything kills over 10 million people..." ensinam como formar hipóteses e condições, um aspecto essencial da comunicação em inglês.
  • Uso do present perfect: Expressões como "we’ve invested a huge amount..." mostram como relatar ações passadas que ainda têm relevância no presente.
  • Palavras de transição: O uso de conectores como "but" e "now" facilita a construção de frases mais coesas e fluentes, fundamentais para manter um diálogo dinâmico.
  • Vocabulário específico: Palavras como "epidemic", "infections" e "preparedness" são importantes em contextos de saúde pública e podem ser incorporadas ao vocabulário do dia a dia.

Armadilhas Comuns de Pronúncia

Ao praticar com este vídeo, você pode encontrar algumas palavras e expressões desafiadoras, que merecem atenção especial para melhorar a pronúncia em inglês. Aqui estão algumas dicas:

  • Epidemic (epidemia): A articulação dos sons iniciais pode ser complicada. Pratique o som "ep" para que ele fique claro e bem definido.
  • Preparedness (preparação): Esta palavra longa pode ser difícil. Tente dividir em sílabas: pre-pared-ness para facilitar a pronúncia.
  • Surveillance (vigilância): Preste atenção ao som "v" e à sequência de vogais. A prática de shadow speak é útil aqui, repetindo após o falante.

Ao incorporar essas práticas em sua rotina, você não só amplia seu vocabulário, mas também se prepara para usar o inglês de forma mais confiante em discussões importantes.

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
