1
Hi, this is Kate from MinuteEarth.
2
India and China together are home to over 2 .7 billion people.
3
That's as many humans as in the next 20 most populous countries combined, or in the whole other 170 countries in the world.
4
Over the last 300 years, India and China each added more than a billion people to their populations — way more than any other country.
5
But they have actually been growing at about the same rate as the rest of the world world.
6
They have a lot more people today
7
because they had a lot more people a few hundred years ago
8
when the world began its period of modern and rapid population growth.
9
It's like comparing a big bank account and a small one.
10
If they both grow at about the same rate over many years, the big one gains a lot more money simply because it started with more.
11
So the billion dollar or billion person question is why did India
12
and China have so many people when they started their rapid growth?
13
We can't know for sure, since so many variables factor into long -term population dynamics.
14
But the two most plausible explanations are food and area.
15
Having lots of fertile land and good access to fresh water makes it possible to grow lots of food, which in turn makes it possible to nourish a lot of people.
16
Even today, the 10 most populated countries in the world all have a relatively large amount of farmland.
17
And Asia, and in particular South and East Asia, has tons of farmland, lots of river valleys, and the ability to grow food year -round.
18
Plus, domestication of plants and animals essentially started in Asia, giving populations an early leg or wing up.
19
As such, Asia's been the most densely populated region of the world for a really long time.
20
Area matters too.
21
Countries like Pakistan and Bangladesh may be filled with farms and densely populated, But because they're smaller in area than India and China,
22
they simply cannot contain as many people.
23
Of course, a few other things happened in India and China in the last few thousand years.
24
Some of them helped the populations grow, and some of them shrank the populations.
25
But through it all, the large and fertile lands of India and China were able to sustain lots of people, such that when the era of modern population growth came around,
26
they had a head start.
27
Or, rather, a hundred million head start.
28
This video was sponsored by the University of Minnesota, where students, faculty, and staff across all fields of study are working to solve the grand challenges facing society.
29
The Minnesota Population Center is helping demographic researchers explore past and current trends in world population.
30
The Global Landscapes Initiative is working to figure out how to keep feeding the world's growing population without harming the planet.
31
And the IPAMS Terra Project integrates global population data with data
32
on the environment to better understand how humans transform ecosystems and how ecosystems transform humans.
33
Thanks, University of Minnesota.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
