Growing world population

One of the major problems for our future is the ever growing number of people living on Earth. We are referring to this in several articles on this site. Below you can find first a graph about the population by geographical area and by year, starting in 1950 until the year 2050.

The second graph shows the population density by geographical area by year, i.e. the number of people living per square kilometre. Further down, we provide lists of the current and predicted population by country. Click on one of the links below to jump directly to a list or graph:

Data source is the U.S. Census Bureau, Population Division (http://www.census.gov/ipc/www/). Data last updated 08-24-2006.

One-Child policy in China

Dear Karf,

The source of the data above is the U.S. Census Bureau, Population Division (http://www.census.gov/ipc/www/). Data last updated 08-24-2006.

So the one-child policy in China is certainly taken into account for the above figures. This is the reason why the population of China is estimated to be almost the same in 2007 and 2050.

World population and global warming

Dear George,

I agree with what you are saying. This was the reason why we took all the effort to provide a "global warming simulation tool" as a spreadsheet model. For this model, there are 3 parameters you can play with:

  • When to start with the reduction of greenhouse gases
  • Increase or decrease in percent per year of the world-wide average carbon footprint (CO2 emissions per capita)
  • Size of world population (increase or decrease in percent per year)

At this link, you can download the global warming simulation model as Excel or OpenOffice spreadsheet.

At this link, you can find some commented results of the global warming simulation model. However the reduction of the world population as you suggested was not taken into account. But if you download the model, you can easily do this yourself.

Best regards

Juerg

World population increase and climate change

Jeff,

The increasing world population is indeed a major problem as stated in the main article above. However it is not really respiration of these people which is causing problems, it is rather the need of these people for food, water, space, energy, etc. The earth cannot sustain an ever increasing number of people with ever increasing demands per capita. The ressources of the earth are limited and so is the number of people it can sustain.

I think the person you queried misunderstood your question. Probably he or she wanted only point out that global warming has very little to do with respiration of people.
