World Population: putting the numbers in perspective

A good friend of mine sent me some statistics that were compiled as part of a study by the University of Wisconsin - Green Bay. The numbers put our world population in a somewhat easier perspective so that we can contemplate many of the social issues facing mankind.

But it also struck me as to how these numbers highlight the importance of how we manage or natural resources - from water to agriculture/aquaculture to fossil fuels and the resulting CO2 damage. And it points to that 800-pound gorilla in the room: our growing worldwide population that is expected to add another 3 billion people in only the next 30 to 40 years.

If the World were 100 PEOPLE:
50 would be female
50 would be male

20 would be children
There would be 80 adults,
14 of whom would be 65 and older

There would be:
61 Asians
12 Europeans
13 Africans
14 people from the Western Hemisphere

There would be:
31 Christians
21 Muslims
14 Hindus
6 Buddhists
12 people who believe in other religions
16 people who not be aligned with a religion

17 would speak Chinese
8 would speak Hindustani
8 would speak English
7 would speak Spanish
4 would speak Arabic
4 would speak Russian
52 would speak other languages

82 would be able to read and write; 18 would not

1 would have a college education
1 would own a computer

75 people would have some supply of food and a place to
shelter them from the wind and the rain, but 25 would not

1 would be dying of starvation
17 would be undernourished
15 would be overweight

83 would have access to safe drinking water
17 people would have no clean, safe water to drink

World Population: guess who is in the room?

When discussing conservation, the environment, or any number of global issues, there lurks in the background the 800-lb. gorilla that no one wants to talk about: human population. Not just populations in 3rd world countries, but global numbers and that includes industrialized countries as well.

If we look at this matter-of-factly, nature has over thousands of years developed methods of equilibrium, checks and balances as it were, all designed to maintain a healthy ecosystem. Whether through predation, disease, or life cycle, all plants and animals are given a chance to flourish within the boundaries of that system or face possible extinction. And humans are part of that equation. However, because of our intelligence (some cynics would say our self-importance) we have exceeded the boundaries of that natural system and are now facing many unintended consequences.

It's a touchy subject to be sure. Who wants to turn to a young child or a close family relative stricken with serious disease and say, "Sorry, it's nature's way." And who wants to consider an Orwellian future where governments control reproduction - regulations like China's one-child policy run amok like some futuristic sci-fi movie. But as long as populations increase, as long as life expectancies are increased, and mortality rates are lowered, then we have a responsibility to consider the consequences in terms of the demands we are putting on the planet as a whole.

There was a time when our ability to feed, clothe and house a growing population was accomplished through our intelligence and our ingenuity. But we are fast approaching the point where we are exceeding what the planet can provide us with in terms of food, resources, and clean air. We must act decisively to control the problems that we have brought upon ourselves and also find the compassionate means to manage a world population of 6.76 billion that has been predicted to increase by another 2+ billion in less than fifty years.

Or we can wait for nature to take care of it . . . coldly but effectively.
