OPAWTY? SOS-Save Our Seas

Three fish holding signs, Send Help!, Please, What he said.As I watch the TV news or read the paper or read science or news magazines, I constantly encounter stories that scream OVERPOPULATION. Often these are about damage to the environment, but there are many others about hunger, desperate poverty, deaths from preventable diseases, war, strife and other calamities.

The July issue of Discover Magazine contained two articles about the ocean that support my concerns.

In “Better Planet - Garbage Patch” (click here for the web version) author Thomas M. Kostigen describes a trip to the Great Pacific Garbage Patch. This is an area in the Pacific Ocean where circular ocean currents trap some of the floating refuse of humans.


“Around and around: bottles, plastic bags, fishnets, clothing, lighters, and myriad other man-made items, held until they disintegrate, make their way to distant seas, or merely bob among the waves before washing up on someone’s beach.”
Unfortunately, much of the material floating here does not disintegrate quickly. Many of these items took several years just to get to the garbage patch which is like a soup made of garbage floating on or near the surface. While the dimensions of this garbage patch are still being mapped, it is believed to be about one and a half times the size of the United States and may reach a depth of 100 feet or more. How much damage is being done by all this garbage is still being studied, but from what we already know, from the damage done to wildlife that often eat plastic thinking it is food to chemicals in the water from disintegrating plastic, the threat is believed to be very serious.

The second article is Ocean Reflux by Kathleen McAuliffe (click here for the web version). It has long been known that the oceans can sequester carbon dioxide as they naturally absorb excess carbon dioxide from the atmosphere. In fact, the oceans were seen as such a good place to store carbon dioxide, there have been suggestions that we pump liquid CO2 into the deepest parts of the ocean rather than let it disburse in the atmosphere and contribute to global warming.

Now new research has found that increasing levels of carbon dioxide in ocean water increases its acidity which may have profound effects such as destroying coral and many of the marine creatures at the bottom of the food chain. Among other problems this might cause, the loss of reefs and small ocean creatures could eventually threaten the planet’s fisheries.

I can’t begin to relay all the scientific details from these two articles, but you can read them yourself if you want more details.

Some scientist or researcher or politician will eventually tell you what we might do to mitigate or reverse these threats, but what you won’t hear them offer is a plan to reduce the number of people on the planet as a way to reduce the damage we are inflicting. Why is that?

OPAWTY? - Virtual Water

Saving the world one cup of coffee at a time.
The June issue of Discover Magazine had an article about virtual water (Better Planet: Virtual Water..., by Thomas M. Kostigen). Virtual water is the amount of water it took to provide a service or item for you - from start to finish. For example, it is estimated that it takes about 1,900 gallons of water to put that one pound steak on your grill and about 53 gallons to put a single egg in your refrigerator.

I'm not sure why these are virtual gallons of water. I am pretty sure I've never consumed a glass of virtual water, but then again who really knows what is in all those bottles we consume. Maybe it is virtual water and that is why we have to pay so much for it.

From the article I learned that like your carbon footprint, you have a virtual water footprint. The average person on earth has a virtual water footprint of about 328,000 gallons of water a year. That is the number of physical gallons of water a person uses directly in a year plus the number of virtual gallons used in a year to produce the food and goods a person consumes and uses. In the United States the virtual water footprint of the average person is about 656,000 gallons a year while in China the average is only about 185,000 gallons - which is good since there are so many more Chinese. If their footprint were as large as ours, they would be very thirsty.

Why are we talking about virtual water? Because we, who live on a water based, water rich world are running out of fresh water. The virtual water concept is supposed to allow us to make better choices. The author, Thomas Kostigen, makes the point that if each of us avoided wasting just one cup of coffee a day we could save enough virtual water to give two gallons of water a day for a year to each of the 1.1 billion people who currently don't have access to clean water. Remember, it is not just the physical water in the cup, it is also the virtual water used to grow the coffee bean, roast it, ship it, etc. Luckily I don't drink coffee so I don't have to carry the guilt of ignoring a billion thirsty people. It took me years to get over the trauma I caused the starving Chinese people when I didn't eat my vegetables as a child.

If the concept of virtual water catches on you can bet it will be added to the content list of packaged food. 180 calories, 0 grams of trans fat and 319 gallons of virtual water.

Let's get real. Are dwindling supplies of fresh water a problem? Yes! But not because we are wasting water on unconsumed coffee. And not because we eat too much meat and not enough grain. The problem is there are too many of us. As the Chinese become more prosperous their virtual water usage will go up. If their virtual water usage even rises to the current world average they are going to be in serious trouble. Likewise, we could cut our virtual water footprint in half, but if our population doubles in 100 years, as might happen, we have put off our problem, but not solved it.

When we are talking about a global water shortage on a water rich planet, people should take note. The problem is not too little water, it is too many people.

Ignorance and Stupidity Are Not Free

Anyone who was an adult during the 1970's knows that $4.00 a gallon gasoline or even $10.00 a gallon gasoline prices are not the worst that can happen. The worst is when you can't buy gasoline at any price.

Anyone who was an adult during the 1970's should not be surprised at the current price of gas. If back then you thought about the issues even a little, you should have known that this day was coming. You couldn't know when and you couldn't know exactly what would cause it, but you should have known it was coming and you should have known that if we didn't plan ahead, the situation could be even worse.

There was a short period in the 70's when people lined up for hours to get gas to fill up their cars. Fights broke out in gas lines as frustration soared and tempers flared. Imagine how your life would change today if you couldn't buy enough gasoline to get to work or drive to the grocery store or if you had to spend hours in line to buy it.

Given the events of the 70's, it is hard to understand why we aren't better prepared today. Not!

Al Gore was accused of proposing a 50 cent a gallon gas tax back in 2000. The rational was that higher gas prices would make alternative energy sources more viable and provide incentives to use this finite resource wisely. I don't know whether or not he really made the proposal, but I don't remember many people thinking it was a good idea. Long term thinking is not a strength that comes naturally to people. It is also not a strength of most businesses (SUVs and large pickup trucks are really cheap right now). It should be a strength of government, but not when people vote their short term self-interests and politicians don't have the character to educate people with the painful truth.

Actually, the current high price of gasoline is one of the best things that could happen to us. The painfully high prices may provide motivation to address the problem before there are severe shortages that would turn a problem into a disastrous. Let me put it another way - a return to $2 a gallon gasoline would be bad for the country.

I do wonder if $4 a gallon gasoline is painful enough. It may take even higher prices. It will also take some time for people to realize that $2 a gallon gas is a thing of the past and accept that difficult changes must be made. I know that many people are struggling with these high gas prices, but there is a valuable lesson to be learned. Ignorance and stupidity may be natural and easy, but they are not free. The high price of gas is an indication that we failed to acknowledge the obvious; oil is a precious and finite resource.

So here is the question of the day - what other important issues are we ignoring because the problem is not obvious or the peril is not immediate or the issues are complicated or the solutions are painful?

Ignorance and stupidity are not free.

OPAWTY?-What is a Pest?

A can of pesticide sprays the Earth.  Has human overpopulation made us a pest?If overpopulation by any other species caused as much environmental damage as human overpopulation does, we would have long ago created an industrial strength pesticide to control their numbers.

OPAWTY? - 4

Should we wait until all the US is this crowded?
Over Populated - Are We There Yet?

The quotes below come from Urban and Slum Trends in the 21st Century by Eduardo Lopez Moreno and Rasna Warah (UN Chronicle Online Edition, The State of the World's Cities Report 2006/7). Emphasis added.


Sometimes it takes just one human being to tip the scales and change the course of history. In 2007, that human being will either move to or be born in a city, and demographers watching urban trends will mark it as the moment when the world entered a new urban millennium in which the majority of its people will live in cities. It will also see the number of slum dwellers cross the one-billion mark, when one in every three city residents will live in inadequate housing, with no or few basic services.


There are now about 6 billion people on earth and 1 billion of those people live in urban slums. Also from the report,

This report unfolds a new urban reality, showing how poor living conditions impact slum dwellers: they die younger, experience more hunger, have less or no education, have fewer chances for employment in the formal sector and suffer more from ill-health.

And finally,

The growth of slums in the last 15 years has been unprecedented. In 1990, there were nearly 715 million slum dwellers in the world. By 2000, the slum population had increased to 912 million and to approximately 998 million today. UN-HABITAT estimates that if current trends continue, it will reach 1.4 billion by 2020.

OPAWTY? - 3

Should we wait until all the US is this crowded?
Over Populated - Are We There Yet?

I watched NOVA on PBS last night, "Dimming The Sun". They described some of the scientific research that proves that airborne particles (and the cloud formations that they facilitate) significantly reduce the amount of sunlight that strikes the surface of the earth. This reduction in sunlight has a measurable cooling effect on the earth.

While this reduction in sun light and the cooling effect might seem to be a beneficial counter to global warming, it also causes problems. Scientists believe it may have contributed to some of the devastating droughts in Africa and, of course, air pollution is a serious health concern.

The most sobering observations were that global dimming has masked the effects of global warming and that as we continue to make progress decreasing air pollution, we will greatly increase the rate of global warming. The current models that attempt to project the rate of global warming do not take into account the full effects of global dimming. We may have much less time to bring global warming under control. Many decades less time. There is a point at which the effects of global warming begin to cascade and there will be nothing we can do to reverse it. Let me say it again, there is a point where reversing global warming will be completely out of our control. That time may be closer than we think.

It has taken decades to convince people that global warming is real. How long would it take to convince people we should stop trying to prevent air pollution until global warming is under control?

I'm sure there are people who will argue that global dimming is just as unreal as global warming, but they've been arguing against global warming for years and so far no good, hard evidence has appeared to suggest they are correct. Global warming is a big problem that will take massive and, probably, painful solutions.

One of the solutions to global warming should be population reduction. Reducing the world's population by itself will not reverse global warming fast enough, but it should be a another tool.

Doesn't common sense tell us that more people on the planet will only make our environmental problems worse? At some point there will be more people on earth than the planet can support. When that time comes we can reduce population several ways: nature can make drastic reductions (disease, famine, loss of habitat), governments can force family planning or we can make voluntary reductions. Since the first two have already occurred in some places, shouldn't we be proactive and start voluntary reductions?

By the way, if we don't bring global warming under control soon, population reduction will occur.

Should we wait until all the US is this crowded?
Over Populated - Are We There Yet?

In the July, 2007, issue of Popular Science is an article entitled Skyscraper Farm about a plan to build skyscrapers to house highly automated hydroponic farms. A farm might be 30 stories tall and feed 50,000 people. Microbiologist Dickson Despommier of Columbia University suggests skyscraper farms as a solution to several problems.

Al Gore has suggested that we grow more trees in response to global warming. Since 40.5 percent of the earth is being used for agriculture, we could move agriculture to skyscrapers and use the land formerly planted in crops for trees.

With the world's population projected to grow from 6 billion to 9 billion, we will need to find additional land to grow food, land we need planted in trees to counter global warming. Skyscraper farms allow a lot of food to be grown on a small foot print of land.

In addition, these hydroponic farms could use and recycle waste water and sewage (after pretreatment) to not only grow the plants, but also to produce clean water by capturing the moisture that evaporates from the leaves. Clean water is another resource that is becoming more scarce. Presumably, skyscraper factories would use less water because water loss due to evaporation would be minimized.

This all sounds fine, except this solution (and problems it tries to solve) are in response to another problem. Over-population. Shouldn't we be talking about ways to minimize population growth and, maybe, over the long term, decreasing the worlds population to a level that is enviornmentlly and economically sustainable without such drastic solutions?

Over-Populated. Are We There Yet?

Should we wait until all the US is this crowded?On the U.S. Census Bureau web site there is a paper written in 2000 that attempts to project the population of the United States through the year 2100. As you can imagine, this is a difficult task, but they do it in a well described, scientific manner. They have to make a large number of estimates about birth rates, mortality rates and migration rates. They ended up with three series of projections based on these estimates using a low, medium (middle) and high rate of population growth (see paper here).

The lowest projection has the population of the U.S. rising to about 313 million by 2050 and then falling to about 282 million by 2100. The middle series projects the population of the United States to continue to grow and reach about 571 million by 2100. The highest series (which I believe is based on a high immigration rate) has the population reaching about 1.18 BILLION by 2100.

Who knows what the actual population of the United States will be in 2100, but what these projections do show is that given the right (or wrong) circumstances, the population of the United States could increase dramatically over the coming decades.

What do you think would be the affects of a population roughly four times the current population of about 302 million people? Would a U.S. population of 1.18 billion be better than a population of 282 million people?

While few of us will see the year 2100, our actions will help determine the future population of the United States. Shouldn't we review the facts and determine what we believe would be the ideal population of the United States and then work to achieve that goal?

Selfish, Selfish, Selfish, ...

I saw part of a show about the Duggar family the other day. While the show tried to portray the parents as loving, sharing, family people, the word that best seems to describe them is selfish.

Each of those kids deserve better than being just one of a litter. They deserve to be raised by parents, not siblings.

Each additional child devalues the others. They are being told that you kids weren't enough to fill our lives, we need to try again.

Selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish, selfish.

Global Resource Bubble

Picture of Earth from NASAEveryone has heard of an economic bubble. One of the causes, as described in Wikipedia is,

The cause of bubbles is often disputed although some experts believe that the cause of bubbles can be explained by the "greater fool's theory." The greater fool's theory explains the behavior of a perennially optimistic market participant (the fool) who buys an overvalued asset in anticipation of selling it to another rapacious speculator (the greater fool) at a much higher price. The bubbles continue as long as the fool can find another (greater) fool to pay up for the overvalued asset. The bubbles will end only when the greater fool becomes the greatest fool who pays the top price for the overvalued asset and can no longer find another buyer to pay for it at a higher price.


There is another kind of bubble, a "psychological bubble" or "reality bubble" where people isolate themselves from other people or situations that they do not want to deal with. This is not a neurosis. We all do it. We construct our own reality that explains who we are, why we are here and our position in the world around us. It is a method of coping.

Sometimes the reality bubbles are physical, such as countries. Sometimes they are emotional, like religion. Reality bubbles can be burst, just like economic bubbles, but this is rare because it is human nature to bend reality to fit our preconceptions.

These two bubbles, the economic and the reality bubbles are at the heart of another bubble, the global resource bubble. We humans like the way the world is developing and we don't want it to stop. The fact that the kind of growth we have experienced up to this point is not sustainable is not a reality we can face or accept. That is why so many people for so long have denied that we are running out of oil or global warming is a reality. That is why people fail to see that the world is already over-populated. If we are satisfied with our standard of living, we want to maintain it. If we are not satisfied, we want to raise it. In both cases, that means ever increasing economic growth, ever increasing population and ever increasing destruction of the environment.

Unfortunately, just like the Dot.COM bubble or the housing bubble, the global resource bubble will eventually burst. Theoretically the human race could manage the situation and evolve our economies to provide an acceptable standard of living for everyone using resources in a sustainable manner, but that is not going to happen.

We are guilty of the "greater fools theory" on a global scale. In this case it is not an overvalued asset we are buying, but an undervalued asset, the very world we live in, and the fools are people not yet born.

Is Illegal Immigration A Problem?

I do not believe that bringing in or allowing in unlimited, cheap, unskilled labor from Mexico is good for the US. It may be good for business. It may help the US economy in the short term, but I don't think it is good in the long term. Certainly, allowing unlimited, illegal immigration is not good for us.

I am not against immigration. We are a country of immigrants. We have a history of welcoming people, educated and uneducated, who are willing to work hard to make a better life for themselves and their families, but we are a country that faces a population problem and unlimited immigration is a big part of that problem. Also, as globalization forces our least educated (and some of our best educated) to compete against workers in other countries who will work for much less pay, we do not need to import more undereducated people. I respect that most of these people are hard working, good people, but we cannot save the world by building a third-world underclass in the US. We are really hurting ourselves by severely limiting the number of educated immigrants and students who are allowed to enter the US and allowing unrestricted immigration of unskilled workers.

I believe we can solve this problem, but I suppose we first have to agree that we have a problem and what it is.

Is the problem that illegal immigrants flouted our laws and entered illegally? Is the problem that these people are undocumented? What should happen to illegal immigrants and their families who are already here? Should they receive amnesty?

Would the problem be solved if we drastically increased the number of people who are allowed to enter the US to take a job so that illegal entry declines just because it isn't necessary?

Is the problem a porous border that not only allows good people just looking for a job to enter, but also allows easy entry for drug runners, terrorists, etc.

Is the problem the public service costs of illegal laborers? Is it the additional family members they bring who also need services?

Is the problem our law which gives US citizenship to any child born in this country even if the mother entered illegally?

Is our current population level over-stressing our environment and natural resources? The US Census Bureau says that most of the US population growth over the next 100 years will be the result of immigration, not births to current US citizens.

Do illegal immigrants depress wages? We always hear that illegals take jobs that no one else wants. If cleaning hotel rooms paid $20 an hour do you think more US citizens would apply?

Is the problem our dependence on cheap labor. How many people benefit because some people are willing to work for less than a living wage? How much would the average person's cost of living go up if all the illegal immigrants were somehow forced to leave?

Is the problem that a large number of people who only speak Spanish are creating a separate society inside the US? Are we looking forward to a bilingual society and problems like the Canadians face? There is always a tension between English and French speaking Canadian citizens. More than once there have been national referendums asking if Canada should be broken up into two countries. One speaking English, the other French. Is that our future?

Is our porous border the conscious choice of politicians who understand that without cheap labor we would face other problems for which they have no solutions? Is it just easier to let this problem fester than take the political heat for really facing the issues?

Do we need to develop an economic system that does not depend on cheap labor and continued population growth?

Obviously immigration, legal and illegal, raises many issues. These are tough problems and we do not respond to tough problems until we have no choice. Even then we tend to take the path of least resistance. While we may not yet agree on the key issues of the illegal immigration problem, we can all agree that there is a lack of clear thinking and leadership in this area.
