Population, Sustainability, and Malthus

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 1800, the human population of the Earth passed 1 billion, and Thomas Malthus posited that growth had hit its ceiling, and the population would level off and stop growing. He was totally right. Just kidding, he was totally wrong! There are like 7 billion people on the planet now! John will teach a little about how Malthus made his calculations, and explain how Malthus came up with the wrong answer. As is often the case, it has to do with making projections based on faulty assumptions. Man, people do that a lot.

Human Population Through Time

It took 200,000 years for our human population to reach 1 billion—and only 200 years to reach 7 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’s resources, even as we approach 11 billion?

This relates to our topic by showing that our population is growing rapidly. By the time 2025 there will be more than 11 billion people on the Earth. But we have enough resources to last us.

America is rapidly aging in a country built for the young

America is rapidly aging in a country built for the young | Education in a Multicultural Society | Scoop.it

"Although we seldom think about them this way, most American communities as they exist today were built for the spry and mobile. We've constructed millions of multi-story, single-family homes where the master bedroom is on the second floor, where the lawn outside requires weekly upkeep, where the mailbox is a stroll away. We've designed neighborhoods where everyday errands require a driver's license. We've planned whole cities where, if you don't have a car, it's not particularly easy to walk anywhere — especially not if you move gingerly.

This reality has been a fine one for a younger country. Those multi-story, single-family homes with broad lawns were great for Baby Boomers when they had young families. And car-dependent suburbs have been fine for residents with the means and mobility to drive everywhere. But as the Baby Boomers whose preferences drove a lot of these trends continue to age, it's becoming increasingly clear that the housing and communities we've built won't work very well for the old."

This is also an issue in Australia where the overwhelming majority of people live in single story dwellings and are very car reliant.

I can definitely see this as a real problem. Both my Uncle and my Great Uncle moved their condos from ones that had numerous steps to climb to the second floor to more elder-friendly options. My Great Uncle even went a step further to move him and his wife to a senior living community, where there food, entertainment, etc. is all provided within an enclosed neighbourhood with other people of their age group. More of these communities that act like oversized retirement homes could be the answer. They give the illusion of suburban living, something the baby boomers liked, while providing the accessibility they need.

Mapping the World's Migration Flows

Mapping the World's Migration Flows | Education in a Multicultural Society | Scoop.it
Visualizing the flow of the world's migrants from country to country.

 

Based on data from the U.N. Population Division, this map shows the estimated net migration (inflows minus outflows) by origin and destination country between 2010 and 2015.

Blue circles = positive net migration (more inflows). Red circles = negative net migration (more outflows). Each yellow dot represents 1,000 people.

Hover over a circle to see that country’s total net migration between 2010 and 2015. Click a circle to view only the migration flows in and out of that country.

For more info about this map, read the article, All the World’s Immigration Visualized in 1 Map.

Migration at a global scale changes places 

 

Syllabus

Students investigate reasons for and effects of internal migration in Australia and another country, for example: 

  • analysis of trends in temporary and permanent internal migration
  • discussion of economic, social or environmental consequences of internal migration on places of origin and destination

Students investigate the reasons for and effects of international migration to Australia, for example: 

  • analysis of international migration patterns 
  • explanation of where and why international migrants settle within Australia 
  • examination of characteristics and spatial patterns of Australia’s cultural diversity

Oldest and Youngest Populations

Oldest and Youngest Populations | Education in a Multicultural Society | Scoop.it

"There are 1.2 billion people between the ages of 15 and 24 in the world today — and that means that many countries have populations younger than ever before.  Some believe that this 'youth bulge' helps fuel social unrest — particularly when combined with high levels of youth unemployment.  Youth unemployment is a 'global time bomb,' as long as today’s millennials remain 'hampered by weak economies, discrimination, and inequality of opportunity.'  The world’s 15 youngest countries are all in Africa.  Of the continent’s 200 million young people, about 75 million are unemployed.

On the flip side, an aging population presents a different set of problems: Japan and Germany are tied for the world’s oldest countries, with median ages of 46.1. Germany’s declining birth rate might mean that its population will decrease by 19 percent, shrinking to 66 million by 2060. An aging population has a huge economic impact: in Germany, it has meant a labor shortage, leaving jobs unfilled."

Demographics seemingly started with age as a metric many years ago and have evolved into marketing tools, political footballs, and ways to combat everything from obesity to social security. Africa is clearly the youngest and probably for a very morbid reason; AIDS and Ebola among other diseases have taken their toll on the sexually active and thus have reduced the average age of their population.

Germany seems to be the place to go for a job as the labor shortage will mean higher wages for the folks who are left. Japan has another issue; a healthy aging population that will strain the government's ability to financially take care of them.

I wonder if the unevenness of Europe is an indication of the two World wars that were fought mostly on the turf. Did some countries lose more than others? If more soldiers, presumably of baby making age, perished did this affect the countries ability to keep pace with the Germany's and Spain's of Europe?

Diet seems to play a large part as well as the Mediterranean is well represented in terms of age. Does their healthy diet of fish, nuts, legumes and olive oil make a difference?

I could spend all day postulating, but I'll leave some of the findings for you to discover...

The median age of a population call be a quite telling statistic--almost a surrogate for a population pyramid.  I post this with a special attention to Sub-Saharan Africa; the youngest 15 countries in the world are all in Africa, one of the major demographic realities confronting African economies and politics.  Here is a map with the median age of U.S. counties.

In the article there are 1.2 billion people between the ages of 15 and 24 in the world today. Meaning that, countries around the world have populations younger than ever! 15 of the youngest countries are in Africa. And of the 200 million young people of Africa, about 75 million are unemployed. The worlds youngest country is Niger with a population and median age of 15.1 and coming in a close second is Uganda with 15.5, but Japan and Germany are some of the Worlds oldest countries ranging in a median age of 46.1!
