Unit 2

Isabella El-Hage's curator insight, March 18, 12:45 PM
This article and video links to Unit Two through "population predictions for the future". This video gives a good representation of how the world's population grew so fast. It's hard to visualize the massive number of 7 billion, and how the number of people born and passed flow into that number, but the cup with the liquid filling in and out made it easier to comprehend. In the past two hundred years the world's population has grown from 1 to 7 billion! Due to advanced technology, and better health care, and agriculture and medicines, people are able to live longer. The UN predicts that the population with hit 10 billion by 2100, but then start to decrease or steady out. I think money needs to be invested in educating women in countries like India about contraceptives and birth control.
