In this video Paul Andersen explains how the world population has undergone exponential growth since the industrial revolution. Predicting the future world population is difficult because each country will grow at different rates. ...

The world's population will grow to 9 billion over the next 50 years -- and only by raising the living standards of the poorest can we check population growth. This is the paradoxical answer that Hans Rosling unveils at TED@Cannes using...

In this video Paul Andersen talks about the impacts of human growth on the environment and on themselves. The population, affluence, and destructive technology of a population impact the environment according to the IPAT equation. An...

The Chinese internet has grown at a staggering pace -- it now has more users than the combined populations of the US, UK, Russia, Germany, France and Canada. Even with its imperfections, the lives of once-forgotten populations have been...

If being alive on Earth were a contest, humans would win it hands down. We're like the Michael Phelps of being alive, but with 250,000 times more gold medals. Today Hank is here to tell us the specifics of why and how human population...

Why is Japan's population ageing? What impacts could this have on the country in future? And how is the government trying to tackle the problem? Human Geography - A Changing World - Learning Points. Japan, like many developed countries,...

In which John Green teaches you about population. So, how many people can reasonably live on the Earth? Thomas Malthus got it totally wrong in the 19th century, but for some reason, he keeps coming up when we talk about population. In...

In which John Green teaches you about nation building and nationalism in Latin America. Sometimes, the nations of Latin America get compared to the nations of Europe, and are found wanting. This is kind of a silly comparison. The rise of...

This video provides an explanation of exponential functions, focusing on the form y = A to the power of X, where A is a constant and X is the variable. The video explains the concepts of exponential growth and decay with real-world...

If you tried to sum up the last 150 years or so in one image, a chart of exponential growth would be a good place to start. It shows that some things change faster over time. You could apply it to life expectancy. Or compound interest....

Is the world overpopulated or underpopulated? While we worry about there being too many people for the planet to support, we can also worry about how fewer people in a given place may affect the economy, what may happen when there are...

Population statistics are like crystal balls -- when examined closely, they can help predict a country's future (and give important clues about the past). Kim Preshoff explains how using a visual tool called a population pyramid helps...

Hank talks about the issues of rising global population.

Today we’ll discuss two theories of global stratification. First, we’ll go over modernization theory and Walt Rostow’s Four Stages of Modernization. Next, we’ll explain dependency theory, the legacy of colonialism, and Immanuel...

This is Texas, the second-largest state in the USA by landmass, population, and GDP.



But perhaps being runner up is not so bad in all of these categories. Texas has for many decades been a huge driving...

In this lesson, students will learn how to determine population growth using an exponential formula. They will review solving for exponents and learn how to deal with exponents inside logarithms. Through examples and calculations, they...

Since the dawn of humanity, an estimated 100.8 billion people have lived and died, a number that increases by about 0.8% of the world's population each year. What happens to all of those peoples' bodies after they die? And will the...

Today, about one-tenth of the world's population are southpaws. Why are such a small proportion of people left-handed -- and why does the trait exist in the first place? Daniel M. Abrams investigates how the uneven ratio of lefties and...

In this math video, we’ll explore how to determine if a table represents an exponential function using a real-world bacteria growth scenario.

We start with a culture that begins with 1,000 bacteria, and each hour, the...

Indian governments have implemented different policies to try to curb the country's growing population. Which has been most successful and why? Human Geography - A Changing World - Learning Points. India's population is one of the...
