How Many Can Live On Planet Earth? Pt 1

A BBC production, David Attenborough narrates this series of six You Tube videos. Part one summarizes the dramatic numbers that have evolved since 1800, moving from one billion people then to almost seven billion today. That means today, everyday, there are two people added every two seconds, 200,000 every 24 hours and 80 million at the end of each year.

What are the forces at work that have escalated the population of the planet from two billion, only a 100 years ago, to almost seven billion today? How will we provide the food, water, and energy required to support an ever growing population, and what is our responsibility to the other creatures and environment we share with this planet?
