Homework - Talking about something interesting

Well, a friend sent me this video this week and I was thinking about the subject, that is about the population of the world. World population could reach the mark of 9 billion by 2045. The planet will be able to sustain so many people? Well, I really do not know, but this video covers the subject of a cool and creative way, which caught my attention. Of course the number of people makes a difference. Even more relevant is the way people consume resources. The main challenge for the future of people and the planet, is out of poverty as many people and at the same time reduce the impact of all of us on the planet. Perhaps this concern with the population numbers are not the best way to confront the future. It's too late to prevent the middle class born in 2030, but not to change the way that we all produce and consume food and energy. According to biologist Joel Cohen, author of "How Many People Can the Earth Support?": "take care that all children are fed enough to learn in school and are well trained enough to solve the problems they will face when they reach adulthood". This would significantly change the future.

I think it's important and very interesting to think about it!
