Acknowledge this Symptom of Overpopulation

October 29th, 2018

By the time  you read this it will be too late to attend the Climate Change Symposium. However, there are several points I want to make by broadcasting information about this symposium:
A small group of committed activists can make a difference in their communities. The Fort Lewis College Environmental Center is a wonderful organization that has reached hundreds of students through the years; their two person staff has taken on this large project with some volunteers and great aplomb.
It is important to involve young people–by the latest count, we will have over 300 high school students attending
Top speakers are willing to come to a little community such as Durango. Katharine Hayhoe will be in Canada, but she will reach us by a video made just for this symposium. We will also be showing one of her YouTube videos. Travis Rieder will be at his office at Johns Hopkins University but communicating by Zoom. Dr. Rieder spoke in Durango a couple of years ago and won a lot of praise for his presentation on the ethical imperative of having small families.
Thank you for reading!

“Humans are at the centre of global climate change: …social change is key to effectively respond to climate change”   IPPC Special Report

Do you remember the politicians in North Carolina who passed a law in 2012 that prohibited calculating sea level rise based on climate change predictions? They said only historical trends could be used.

That law, promoted by real estate developers, postponed planning for the consequences of climate change. Only 6 years later they were visited by a wrathful storm that dropped 3 feet of rain on parts of the state!

I wonder how the legislature feels now that they have been visited by reality in the form of Hurricane Florence. (Although the law concerned sea level rise, immense precipitation caused the damage.) My hope is that legislators have learned that they cannot mess successfully with the laws of nature and physics.

Many of the changes we’re experiencing now are due to anthropogenic (human caused) climate disruption. The list includes more destructive hurricanes; the estimated cost of Florence is 38 billion dollars and the human toll is 53 deaths.

Michael is the most recent hurricane; it was another monster. Almost a category 5 storm, it hit with terrifyingly destructive winds. There was “unimaginable destruction”, to quote Florida’s Governor Rick Scott. “So many lives have been changed forever. So many families have lost everything. Homes are gone. Businesses are gone.” 

Yet Scott does not believe in climate change. Apparently staff at the Florida Department of Environmental Protection were told not to use the terms “climate change” or “global warming” after he became governor.

Why have we been punished with so many destructive storms recently? Part of the problem is that governments are failing to recognize that climate change is increasing the frequency of these deadly and costly storms. Even a slight increase in the air and water temperatures gives significantly more energy to form cyclonic storms.

Senator Inhofe of Oklahoma wrote a book about climate change titled “The Greatest Hoax”. I don’t think that people in Florida and the Carolinas will be reading that book much now.

How is it possible that some people who don’t believe that climate change is real, or think that it is all just natural cycles that are causing it? How is that possible when these people know that humans are increasing greenhouse gases in the atmosphere? How does one talk with someone who denies climate change?

“Climate Change Solutions” is the second symposium at Fort Lewis College on the subject. It will be held Tuesday October 30th. Last year’s meeting focused on the science, this year will focus on ways that individuals can help deal with this global problem.

The symposium is coming just in time! Evidence is mounting that there is urgent need for solutions to climate change. Earlier this month the Intergovernmental Panel on Climate Change (IPCC) published a special report which can be summarized: “…drastic action must be taken in limited time to avoid severe and worsening consequences.”

Highly respected climate scientist Kevin Trenberth was one of the speakers last year. He wrote: “…humans are the main agents of change.” This is a bit ambiguous; in context, he meant that climate disruption is anthropogenic. It can also mean that we can also solve this global problem. Trenberth explained the destructiveness of this summer’s storms thusly: “While hurricanes occur naturally, human‐caused climate change is supercharging them and exacerbating the risk of major damage.”

Climate Change Solutions will have 2 sessions, starting at 12:30 and 6:30, at the Community Concert Hall on the Fort Lewis College campus. Because cimate change will affect today’s kids much more than my generation, we have invited several hundred students from area high schools. All College people will have free admission.

A member of US Senator Michael Bennet’s staff will urge people to vote for politicians who don’t deny climate change, and update us on what is happening in Washington to fight this global disruption There will be suggestions about effective ways to talk to climate change deniers.

Another speaker will tell us about the most effective way to quell climate change. You guessed it! Climate change is really a symptom of overpopulation and of overconsumption. Choosing to have a small family is the most effective action in the long run an individual can take. We also need actions that will work in the short run.

Avoid these Causes of Infertility

September 30th, 2018

A solution has been found for overpopulation! Unfortunately, this is not a reason for celebration.

This essay is another in my all-too-long series of bad ways to control population. It joins essays on genocide, the Doctrine of Discovery and gun violence.

Sperm counts are declining around the world. Fortunately, most men still have enough sperm to become fathers when they want, but that might not be the case forever. There are even predictions, if the current trend continues, that the human species will cease to exist! Just how worried should we be about declining sperm counts?

A review article suggests that the average sperm counts in European and other “western” countries has declined markedly. The overall count has declined 50 to 60% from 1973 to 2011. Another study found the same—or worse—is true for Africa. Between 1965 and 2015 they found a decrease of more than 70%! Fortunately, as you remember from biology class, only one pollywog fertilizes an egg. However fertilization requires that a crowd accompany that one lucky sperm.

I look at these studies with some concern about their accuracy. However, it seems that men truly are making fewer sperm. In addition to this decrease, genital abnormalities and testicular cancer have become more common. What is affecting men so badly? Perhaps we can learn something by consulting “man’s best friend”.

Veterinarians have studied the reproduction of a group of guide dogs for decades, and found decreases in sperm quality and increases in genital abnormalities and testicular cancer. The dogs seem to reflect the same problems as men are facing! The question is: what is causing these problems?

The vets did something that most men would object to—testicular biopsies. These little bits of tissue were tested for several chemicals with names such as “PDBE28” “PCB153” and “DHEP”. The chemicals were found in the dog food, and in the biopsy tissue, too, in levels that inhibit fertility.

These chemicals have been developed in the last few decades to promote “better living through chemistry”. They are some of a huge number of organic chemicals that have beneficial uses and have found their way into our homes—and into our bodies.

Although we may not be aware, when we bring home new furnishings, they are often treated with chemicals such as PDBE28 to decrease the rate at which they burn. These chemicals are also in building materials, vehicles and plastics—they are ubiquitous. They may have saved lives because of their fire retardant properties, but they may also have changed many lives because of their biological effects. Almost all—97%—of people in the USA have detectable levels of this group of chemicals in their blood!

The shape of these artificial molecules is similar to the shape of some hormone molecules. Hormones are chemical messengers that tell distant parts of our bodies what to do. They fit into receptors that receive hormonal molecules and activate cells. The analogy of lock and key is often used because the hormonal molecule is usually specific to certain receptors on certain cells. Because their shape is similar, endocrine disrupting chemicals fit in receptors. The disruptor can either stimulate the cell or, if the “key” gets stuck in the “lock”, the disrupting chemical can block the action of the real hormone.

Switching to women, now. Female fertility is also decreasing. The epidemic of  obesity is affecting fertility, as is some women waiting too long to have children. Their bodies are also sensitive to the effects of endocrine disrupting chemicals. In a study of California women, those with high levels of PCBEs took longer to conceive a pregnancy than women with lower levels. 

There hasn’t been enough written in the press about endocrine disruptors, perhaps because this subject is very complicated. Two facts that stick in my mind are that endocrine disruptors have their strongest effect when they are very, very dilute— because of their combination of stimulating and blocking effects. This means that the usual testing done by the FDA may find little risk because they didn’t dilute the chemical enough—the opposite of the usual when testing for toxicity. Indeed, endocrine disruptors may have an effect when they are equal to a pinch of salt in an Olympic-sized swimming pool!

I plan to write more about endocrine disruptors since they are so pervasive and have so many bad effects. Time will tell if these chemicals will cause a significant decrease in our population. If they do, it will be involuntary—which is tragic.

Solve Climate Weirding

August 28th, 2018

The summer isn’t over and already the fires have been terrible. What is causing all this trouble?

We had the huge 416 fire just north of Durango. Over 54,000 acres of our precious land has burnt in this fire alone, and there are many other wildfires near by. The 416 was terrible because it was so close to Durango, and because it was apparently started by an ember from our beloved Durango and Silverton Railroad.

Much of the American Southwest is experiencing exceptionally dry conditions. I recently discovered that there are four levels of drought, according to National Integrated Drought Information System (www.drought.gov). Much of the Southwest is at the worst level—Exceptional Drought. Unfortunately, we are not alone.

My wife and I recently traveled in Scotland and Norway. It was dry everywhere, with brown replacing the usual green. We didn’t need warm clothes the we packed since we were well inside the Arctic Circle. We wandered around the North Cape of Norway—the farthest north of that northern country—with only light jackets. 

Greece has suffered from disastrous fires, with the loss of many lives. Even northern Sweden is suffering from wildfires, which is very unusual. What is causing this hellish inferno? 

Of course, part of the answer is global climate change, which I like to call “global weirding” because different places get hit in different ways. While we are suffering from drought, the Northeast has been inundated with floods.

Almost all scientists agree that the climate is “weird” because of our use of fossil fuels. A recent article from Science supports this. The temperature changes in the north latitudes have been found to match the “fingerprint” of what computers predict, giving still more credence that climate change is anthropogenic. The article’s conclusion is: “Our results… provide powerful and novel evidence for a statistically significant human effect on Earth’s climate.” 

Not all people are affected by climate change equally. The far north is heating up faster than the tropics. Poor people also get the brunt of this weirding—they are more likely to work outside or to live in high density cities with the “heat island” effect. On the other hand, the fortunate among us can resort to air conditioning.  However, AC is counterproductive in the long run since most electricity is generated with fossil fuels.

What can be done to slow climate change? In the short run reducing carbon emissions will help. We donate to offset our carbon emissions to organizations such as American Forests. Having small families is the best way to reduce carbon emissions for the long run. That is because each additional person added to the population increases carbon emissions—the fewer people, the less greenhouse gases. If you look at all the future generations that are likely to follow a child born today, the effect of having one fewer child is huge.

Last year Fort Lewis College hosted a symposium on the science of climate change. We were hoping to have 200 people attend and were pleased that there were almost double that number! Most impressive was the teacher of a high school environmental studies class in Cortez who brought her students. Encouraged by such a good response to last year’s meeting, I am helping to organize a second event—“Climate Change Solutions”. It will be held at Fort Lewis College on October 30th. Please save the date!

There will be an amazing lineup of speakers, two of whom will decrease their carbon footprints by appearing digitally. Senator Michael Bennet’s staff—or perhaps the senator himself—will be there in person. The senator is not campaigning for office this year but will update us on what is happening in Washington and Colorado to slow climate change. We will have a return visit from philosopher Travis Rieder who gave a wonderful Lifelong Learning talk last year on the ethical imperative of small families. Dr. Katharine Hayhoe is a climate scientist and member of the Nobel Prize winning International Panel on Climate Change. She and Dr. Karin Kirk, a member of the Yale Climate Connections, will be focusing on communicating about climate change.

Climate Change Solutions will have two sessions that Tuesday—one in the afternoon and one in the evening. Both will be open to anyone, but the afternoon is especially for students; we are arranging for 380 students from local high schools to attend. After all, it is they who will suffer the most from climate change. We won’t solve climate weirding at this symposium, but people can learn ways to slow it down.
