This web site is interesting. You put in your birthday and it tells you what number person you were on the earth. I'm roughly the 77 billionth person to have lived and the 3.2 billionth person alive when I was born. If you follow through the pages you learn a little bit about the population growth and its implications. One of the more telling quotes was:
- It is estimated that your group of the richest countries consumes double the resources used by the rest of the world. The UN estimates that if current population and consumption trends continue, by the 2030s we will need the equivalent of two Earths to support us.
take a look for yourself.
