In this video it talked about how we are going to be one of 7 billion people on earth now in 2011. They say, that in 2045, the population could be 9 billion. It would take over 200 years just to count to 7 billion out loud and that 7 billion steps would take you around the world 133 times. About every second, 5 people are born and 2 people die. Nearly everywhere, we are starting to live longer. In 2010, the average person lived up to 96 years old. but in the 1960's, the average person lived up to 23 years old. In 2008, for the firs time ever, more of us lived in cities than in rural areas, for example, country side. In megacity's the population is around 10,000,000. In 1975, there were 3 megacities, Mexico city, Tokyo and New York. Right now, there are 21 megacities. By 2050, 70% of us in the world, will live in urban areas. But we don't take up as much space as you think we would. Standing shoulder to shoulder, all 7,000,000,000 of us, would will fill the city of Los Angeles. So basically, we don't need space, we need balance between us and the planet. Only 5% of us, consme 23% of the world's energy, 13% of us don;t have clean drinking water, 38% of us lack in Adequate Sanitation.
