1
This banana is known as the Gros Michel, aka Big Mike.
2
And it nearly went extinct.
3
Hard to imagine because the myth that bananas are ubiquitous is so ingrained in our minds.
4
I'm Chiquita Banana and I've come to say...
5
Bananas in pajamas.
6
Now let's go bananas!
7
So Mauricio Catalan's comedian is composed of a single banana.
8
It is the number one grown fruit in the world,
9
the most consumed fruit, the most important fruit crop.
10
It's the, I think, the weirdness of bananas that makes them so interesting.
11
When Big Mike disappeared from the market,
12
it was replaced with something very similar, the Cavendish banana.
13
And you probably recognize it as the banana,
14
since it's pretty much the only banana we see in the US.
15
By the 1950s, Cavendish became the most commercially successful banana.
16
Bananas are so good for you and so easy to digest.
17
But a variant of the same disease that virtually wiped out Big Mike is coming for the Cavendish.
18
And this time, there's no replacement.
19
So what needs to happen to save our beloved banana?
20
Bananas are fascinating fruits.
21
They're part of the genus Musa and are full of potassium and an energy-dense food,
22
making them a staple crop in much of Africa, Asia, and Latin America.
23
They originally came from Asia,
24
likely somewhere in Southeast Asia.
25
The wild ones are full of of seeds.
26
So a wild banana is going to be about the length of your thumb here.
27
And these banana seeds are rock hard, tooth shattering.
28
To get to the seedless bananas we have today,
29
humans basically had to find sterile fruits.
30
It was probably a mutation that did this.
31
Some of these early farmers found a banana that was seedless and watched it propagate and said,
32
hey, you know, we can cut this sucker off,
33
this daughter plant, and take it somewhere else.
34
And the daughter plant gives birth to another plant.
35
And this can go on for thousands of years.
36
This method of reproducing through propagations is also known as asexual cloning.
37
But it also creates some problems because these fruits are essentially now clones
38
and they're all exactly the same and they carry the same weaknesses.
39
And this genetic cloning is really where the danger starts.
40
Commercially farmed bananas, which are pretty much all of the bananas we consume, are monocrops.
41
It's an industrial agriculture term that refers to single crop species grown on the same land again and again.
42
It's driven by our demand for uniform, durable, and cheap fruit.
43
The variety they picked was a banana called the Gros Michel.
44
The Gros Michel is a great banana for commercial use because it's tough.
45
It doesn't need to be packaged really that much.
46
It ripens at a perfect rate.
47
The result?
48
Uniform bananas for consumers like us,
49
but extremely fragile biological conditions for the plants and the farmers.
50
You run a risk, which is that if one of your bananas gets sick,
51
all of them are gonna get sick.
52
And that was exactly what happened with Panama disease,
53
or Tropical Race 1, in the early 1900s.
54
The plantations begin to get very sick.
55
Fungus invades the soil, making it impossible to grow the bananas.
56
But instead of diversifying, industrial banana companies acquired more lands as the plantations became diseased.
57
And all goes well until they finally run out of land.
58
This is partially how the term banana republic came to be.
59
It's an ugly history that involves US corporations like the United Fruit Company exploiting land and labor in Central America.
60
These companies took over farms and governments to grow exports like bananas cheaply and at a massive scale.
61
But no amount of land in Conquest could stop the spread of Panama disease.
62
By the 1950s, TR1 had devastated the Gros Michel globally,
63
virtually wiping it out of production.
64
Luckily, the Gros Michel had a close cousin that was resistant to that strain of Panama disease,
65
the Cabin dish.
66
At the brink of extinction,
67
at the brink of disaster,
68
the banana industry saves itself,
69
when in fact it is only delayed an inevitable fate that will come back to haunt it again.
70
Speaking of delicious bananas, this video is presented by a delicious yogurt, Stonyfield Organic.
71
For over 40 years, Stonyfield Organic has been a champion of truth in our food system.
72
There is so much misinformation out there,
73
which is why they believe in using the highest quality ingredients to ensure
74
that what they put on the shelves is the best product for you and your family.
75
The milk they use comes from all over the country,
76
including Molly Brook Farms in Vermont.
77
It's USDA organic certified, which means no growth hormones, no pesticides, no antibiotics.
78
So the next time you're in your grocery run and you're thinking about bananas,
79
make sure to also check out Stonyfield Organic Yogurt.
80
It's also important to note that Stonyfield Organic did not dictate the content of this video,
81
but their support did make this tasty reporting possible.
82
And now back to bananas.
83
By the 1990s, the Cavendish was facing a new strain of the Panama disease,
84
Tropical Race 4 or TR4.
85
The banana companies refuse to believe it and they just keep doing what they're doing.
86
The disease started in Taiwan in the late 80s.
87
From there, it spread to Africa, Australia and the Americas.
88
By late 2025, TR4 is reported in Ecuador,
89
the largest banana exporter in the world.
90
This disease is really virulent.
91
If I am wearing a sneaker with one bit of contaminated soil and I walk through a banana plantation,
92
I'm gonna spread that disease.
93
But unlike what happened with Gros Michel in the 1950s,
94
there is no banana cousin to replace the Cabin dish with.
95
So we're in the situation now where this disease is really starting to have a dramatic influence.
96
And all of the major producers around the world are now recognizing at long last things have to change.
97
Now, it's not like other bananas don't exist.
98
There are actually over a thousand species of bananas.
99
With specialty farms and supermarkets,
100
you can even find some of these other varieties.
101
There's certainly been a move to try to move consumer preferences from Cavendish to something else.
102
Consumers didn't like it.
103
Didn't taste like Cavendish that preference is such an incredible driver.
104
And to try to get consumers to change from a Cavendish banana to something else is going to be a big ask.
105
So Professor Dale turned to science.
106
My group started to genetically modify bananas.
107
So we know there is resistance to the Panama disease tropical waste fall.
108
It actually occurs in one of those wild bananas we were talking about,
109
the ones with seeds we pulled one gene out of that banana and transferred it to Cavendish.
110
But as you can imagine,
111
consumers have a lot of skepticism around genetically modified foods.
112
At this time, in March,
113
2026, Professor Dale's lab-grown Cavendish bananas are not yet available in stores.
114
We've now had approval to grow,
115
commercially grow that banana in Australia,
116
but nowhere else in the world has yet.
117
Genetically modified crops are highly regulated.
118
So Europe at the moment is very reticent on taking any genetically modified foods.
119
And the other thing, of course, is consumer perception.
120
While his modified banana will likely never make it into the European market,
121
Professor Dale has other solutions like gene editing.
122
In many countries, this is no longer considered genetic modification.
123
There are many, many other crops that are being gene edited and some of them are already on the market.
124
So, to save our beloved banana,
125
either Western consumers will have to give up on the myth of there being only one type of banana,
126
or regulators are going to have to accept genetically engineered Cavendish.
127
I think we're going to have to have an open mind
128
about how we're going to produce our crops under what are becoming increasingly extreme conditions.
129
Though truthfully, science can only do so much.
130
The answers for preserving our beloved banana and the future of many of our fruits lies in maintaining a diverse ecosystem.
131
How do we fix the problem?
132
And the answer is destroy the monoculture.
133
We need to get all those bananas that are so good to the United States,
134
to Europe, to the Western world,
135
because that's the only way to sort of protect the banana and to protect people who grow bananas.
136
What I would love to see would be when you walk into a supermarket,
137
that still the bananas are right there front and center,
138
but there are 10 different ones.
139
Cavendish over here and maybe Ladyfinger and bananas would go from the world's favorite fruit to even more favorite.
140
Alright so we got all of these bananas for this shoot
141
and we want to do a blind taste test to see
142
if we can actually identify which one is Cavendish and also see
143
if we like one of these bananas better shout out to the Thai
144
and Filipino markets for actually having such a diverse array of bananas
145
and we're gonna put the results of the blind taste test up on Vox's Patreon.
146
If you're not yet a member go on over to patreon.com slash Vox.

- Cavendish: Từ này có thể dễ dàng gây nhầm lẫn do cách phát âm không giống với cách viết.
- Gros Michel: Khó khăn nằm ở âm "Gros", phát âm không phổ biến trong tiếng Anh.
- monocrops: Âm tiết đôi khi có thể bị nhấn mạnh sai, dẫn đến cách phát âm không chính xác.
Chìa khóa để vượt qua những cạm bẫy này là sử dụng phần mềm shadowing để luyện tập phát âm chính xác từ các video như thế này. Hãy cố gắng nghe và lặp lại theo từng câu, điều này sẽ giúp cải thiện kỹ năng nói của bạn một cách đáng kể.
Phương Pháp Shadowing Là Gì?
Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
