7 Billion People-Overpopulation or Not?


Did you know?

Many watched a National Geographic YouTube video (http://www.youtube.com/watch?v=sc4HxPxNrZ0&sns=em) that circulated around the web about the world’s population passing the seven billion mark in 2011. The video cleverly lays out simple statistics on the state of human population, the earth, human consumption, and the probable future of these three elements

The National Geographic video states:

By the end of 2011, the population of humans will reach and begin to exceed seven billion people. In 1800, only one billion people lived on the earth.

For every one second that passes in time, about five people are born and only two people die.

Our average life expectancy is longer. In 1960, the average life lasted 53 years. In 2010, the average life lasted 69 years.

In 2008 and for the first time in human history, more people live in urban areas than rural areas. By 2050 more than 70 percent of the world’s human population will live in urban areas.

In 1975, three megacities existed. Now there are 21 cities categorized as a megacity (with more than ten million people).

All seven billion people could reportedly stand shoulder to shoulder in an area the size of Los Angeles.

The video goes on to describe how overpopulation concerns are not about space, they are about balance.

They report that five percent of humans use 23 percent of the energy being used. 13 percent of humans can’t obtain clean drinking water, and 38 percent of humans lack “adequate sanitation.”
