What's Left?

A graphical accounting of the limits to what one planet can provide

We have to worry with Global Warming, but also with another problem: We are running out on resources.

The info-graphics produced by Michael Moyer, shows us a world that's almost without resources and running for its extinction. 

Is the planet overpopulated?

The exponential growth of human population peaked in 1987. That year 87.01 million more people were added to the Earth. Since 1987, the population has declined on average by 2.1 million less people added per year. In this year of 2000 the population will increase by 60.1 million people. If we maintain this 13 year average of 2.1 million less people added per year, we will peak in population reaching zero population growth in 2029 with 6.90 billion people.

The decline of human population has been even more dramatic over the last 6 years. In 1994 we added 78.5 million more people, this year we will add 60.1 million. This is a decline of 3 million less people added per year. If we maintain this 6 year average of 3 million less people added per year, we will peak in population reaching zero population growth in 2020 with 6.64 billion people.

In http://www.overpopulation.net/

United Nations expects that we'll have ten billions of people in 2050 and we rich the limit of 11 billions in 2100.

In the following graph we denote that resources are falling and the population will stop growing in a near future.

Are we lost or have a salvation?
