Dear Friends,
LISTEN TO THIS WEEK’S PROGRAM:
1. Population bomb, with Nicholas Johnson
2. Robots, crypto currency, and the biggest rogue state
3. Expectations of a new state lawmaker, with Rep. Mary Madison
4. The twelve foods of Christmas that we have yet to try, with Kathy Byrnes
Nicholas Johnson
I know some pretty amazing people. Many have been doing cutting edge work all their adult lives. (Sometimes, that work is better described as bleeding edge.) One of them is Nick Johnson. Nick’s a retired law professor. He also served on the Iowa City school board and on the Federal Communications Commission. That’s the short list.
One of the issues Nick’s not afraid to tackle is global population. I’m going to pass the baton and share what Nick wrote earlier this year on the subject. You can hear our conversation about it during the opening segment of this week’s program. Feedback welcome, as always, and I’m happy to pass it along to Nick.
A global warming win-win-win (by Nicholas Johnson)
Can women cool global warming?
Homo sapiens first appeared about 300,000 years ago. We’ve been growing rather than chasing our food since 10,000 B.C. Estimates of the population then are between one and 15 million people.
With more food available, villages evolved and population increased dramatically.
Yet, it took until 1803 to reach 1 billion people. Then 124 years to reach 2 billion; 33 years to reach 3 billion; and 15 years to reach 4 billion.
Need I say more?
Apparently so. Because most of what we’re told about environmental change and daily disasters stops with the phrase “climate change.”
Many are willing to do their part. To borrow from the Great Depression, they “use it up, wear it out, make it do, or do without.” They become vegetarians, bicycle or walk to work, turn up the air conditioner thermostat, recycle, compost, and grow some food.
That’s good citizenship in a crisis. But it only offsets a tiny fraction of the problem.
In fact, many of our environmental problems have been created, or at least made worse, by the rapid increase in the rate of human population growth. One example: humans are responsible for a 1,000-fold increase in other species’ natural rates of extinction.
The increase to 8 billion of us also multiplies potable water shortages, polluted air, deforestation, wetlands destruction, increased trash and toxic waste, depleted fisheries and finite resources, increased farm, river and ocean pollution and acidification, and the substitution of concrete for agricultural land and open spaces now under sprawling communities and 4 million miles of roads.
Human activity is not only responsible for most of the greenhouse gas CO2 since our industrial age. We have also reduced the forests and soils that could remove and store it. Our country creates the most — and at a rate seven times per person that of China, number two.
Transportation creates the largest share of U.S. emissions.
In 1922 the U.S. population of 110 million was driving 111 vehicles per 1000 people (12 million vehicles). By 2012 the population was 314 million, but the number of cars per 1,000 population had gone from 111 to 808 (271 million vehicles).
Say what you will about fuel efficiency and electric vehicles, more people driving 20 times more vehicles produce more CO2.
Exponential population growth is an environmental challenge for the U.S., but especially developing nations.
Fortunately, women will naturally reduce population growth if they are provided the support they deserve: social status, economic opportunity — and education. Women (and men) with secondary education and access to contraceptives have far fewer births. They space more time between pregnancies. Plus, their children also end up with better health, quality of life, and education.
We ought to be doing this anyway. Saving our planet is a bonus.
After writing this I discovered 21,000 scientists agree: “We are jeopardizing our future … by not perceiving continued rapid population growth as a primary driver behind many ecological and even societal threats.” Think about it.
