Bottom line is, you can’t really talk about how many people the planet can support when things like fertilizer keep being invented, but you can talk forever about population shift. Then I read a book called “How Many People Can the World Support,” by Joel Cohen which is all about all the predictions for the planet’s carrying capacity over the last couple hundred years and how each prediction was wrong. When I started photographing the “7 Billion” story for National Geographic Magazine, I thought I would be doing a story about carrying capacity-basically that there are not enough resources and there are too many people and we are going to be screwed in a Malthusian way. In the past fifty years alone, the world’s population has more than doubled. Two hundred years ago, there were only 1 billion people on the planet.
This schizophrenia just ends up hurting the tired, poor, huddled masses, and ultimately all of us.Īccording to the UN, the world’s population reached 7 billion on October 31, 2011. Add to this the schizophrenic immigration laws in places like Russia where they push former Soviet Bloc workers out with one hand and with the other hand create programs that have huge incentives for the same workers to come in to their under-populated country. As the world’s population reaches 7 billion in 2011, 8 billion in 2025, and 9 billion in 2043, the repercussions for all of us will depend on how people move around our planet and the decisions they make as they go. Like a rising tide-which you can watch from a lawn chair, willing it to stop, but it will rise anyway-immigration is an economic necessity that cannot be stopped. The empty pockets need good educations and salaries and the empty nests need workers to take care of them. As the empty pockets in Sub-Saharan Africa produce a huge population of young workers, the empty nests in Japan are building robots to take care of their elderly because they can’t import enough Filipinos. Immigration: In this urbanized world where rich, poor, young and old from all cultures and with different customs and speaking different languages are packed more and more tightly together in places as unlikely as Cleveland, it may be hard to see how much these diverse groups actually need each other-but they do. 7 Billion Humans | Immigration By Randy Olson
