There are so many things happening in the political world these days that it’s hard to decide which to highlight. That being so, why not go for the biggest, the most menacing, the one that has the greatest overarching effect on all of us—namely, climate change, the warming of the very globe we all call home?

Yet the topic of climate change, in and of itself, is too vast and complex for any one article. It needs to be broken down into component parts. There are innumerable ways of approaching the myriad of issues related to it. But one that is surely among the most important, and yet which gets far less attention than it should, is that of overpopulation. In 1944, the year I was born, the world had fewer than 2.2 billion people in it. Today there are nearly 7.5 billion, an increase of more than 5 billion in the space of 73 years. Predictably, we will also see that number rise to 8 billion by 2024, and to 9 billion in 2042. What are we to do with all these people? How to feed them? Where to house them? Where to find enough arable land to grow crops for them? How will they make a living for themselves and their families? And what will be the effect of vastly increasing numbers of humans on the environment?

As daunting as these figures and these questions may be, hiding from them is not an option. We must look at them head on and not flinch. Once recognized, we then have to decide what to do about it, how to change what we otherwise know is coming. And, although it may be tempting to go to what seems like the simplest and most direct solution, that is, for people to have fewer children, as true as this may be, that option has not proven to be a particularly feasible one, at least as far as governmental regulations are concerned.

The one exception is China, with its now defunct one child policy. The population increase there has leveled off markedly in the last several decades, since the inception of the policy. For example, there were 33 births per thousand women in 1970, but only 15 births per thousand in 1998. This is an enormous difference, but the decrease comes with its own set of problems. Boys, always more desired in traditional Chinese society, were wanted and kept, while girls were often aborted, or sometimes even abandoned at birth. As a result, there are unnaturally more males in the population today than there are females, a major demographic and societal problem. And the rapidly aging population of China now has far fewer younger citizens to help support their elders in retirement. Additionally, it’s obvious that no western-style democracy would ever be willing, or able, to put into place the kinds of prohibitive restrictions the Chinese government did.

The best control on population growth is, and always has been, education—and education for girls, in particular. Note, for example, that the number of births per woman in Japan is 1.3; that same number for Guinea-Bissau is 5.7 births per woman. According to the Earth Policy Institute, “One of the most effective ways to lower population growth and reduce poverty is to provide adequate education for both girls and boys. Countries in which more children are enrolled in school—even at the primary level—tend to have strikingly lower fertility rates.” Let’s hear it, then, for more education.

But we know that there exist a number of obstacles to the education of children. Many countries are simply too poor to offer adequate teaching facilities for a large majority of their children, and there are others where social, religious and cultural factors prevent girls in particular from receiving an education. All of which points to a substantial likelihood that world population will continue to rise, at least for the foreseeable future. It’s therefore incumbent on us now to do what actually is in our power to help counteract the most deleterious effects of overpopulation.

The Trump Administration has already demonstrated that it does not believe in global climate change, or at least that the warming of the globe has anything to do with human activity. This perhaps should not be all that surprising. According to the Pew Research Foundation, almost three-quarters of Americans don’t trust the consensus of 97% of world scientists, who assert otherwise on climate change.

When it comes to actual numbers, however, and to hard data related to worldwide temperature variances, this is not really a question of belief. To cite one recent example, of the thousands that could be given, this past February was the warmest February on record. If the world really is warming, regardless of whom or what we believe may be responsible, it’s imperative to try to do something to prepare and protect ourselves and our environment from its worst effects. Decreasing the amount of fossil fuels used is what is most frequently suggested. And that must be done. But here, again, we run into corporate, and now governmental, doubters. If you don’t believe in human-induced global warming, why should you do anything about it?

Where, then, does that leave us? Fortunately, we do not have to rely solely on government at the federal level to effect changes. These days, a majority of the work is being done at the state and local level. And while I’m of the opinion that we need more than that, sometimes in the moment we have to take what we can get. Additionally, it’s encouraging that many businesses, and the military, have weighted in on the need for action to address global warming.

One plan that has gotten recent press (see “Housing is key factor in climate goals” in the Los Angeles Times, March 6, 2017) puts the emphasis on greater collectivity within cities—in other words, population density—as a way of drastically reducing commuting and the consequent use of gasoline. The idea, obvious enough, though not necessarily easy to accomplish, is to create urban spaces where people can both live and work in their own neighborhood. This eliminates the need for long commutes by car, and it allows people to get to jobs and places to eat and shop and play that are either within walking or biking distance, or that can be readily reached via fast, clean, affordable and reliable public transportation.

What’s being suggested is not so different from the kind of city I grew up in the 1940’s and 50’s. My family did not have a car, and that fact never felt to me like a burden. My father walked to work every morning; my mother took the bus to the department store where she worked; and my brother and sister and I all either walked or took the bus to school. The local grocery—a literal corner store—was a block away, and we lived across the street from our parish church. Sometimes, it may be that what was good was mistakenly discarded in the pursuit of what we like to think of as progress.

This new, or not so new, concept of closely packed housing near places of work and shopping and worship may not be welcomed by all. We have grown accustomed to driving in our private cars, sometimes long distances, to work and elsewhere. The concept of the soccer mom has become so acceptable as to even go unnoticed. Meanwhile, she drives her children hither and yon to team practice, to sporting events, and even to parent-arranged “play dates.” What ever happened to kids playing with others in the neighborhood? Some of the most affordable and desirable housing has been put up in sprawling suburbs with few amenities within easy reach. It is not uncommon in places like Los Angeles for an individual to drive an hour, even an hour and a half, each way to and from work.

As much as we may wish for a house in the suburbs with three bedrooms and two baths, it may be that we have to face the fact that it is, in the long run, unsustainable. And if it is difficult to maintain now, with the population we currently have, what will happen in 2042, when there are 9 billion people on the planet? The idea of attempting to reduce some of the excesses of overpopulation through the encouragement of urban population density is of course not a panacea. Indeed, like most things, it falls far short of a complete solution, and it brings with it its own pluses and minuses. It is, though, one of the many factors about which humans will have to make choices in the coming years, if we are to hope that our children, and their children, will be able to live on a healthy planet.

The truth is that change is coming, whether we like it or not, and whether we acknowledge it or not. Surely, it is better to look directly at what will be, and to make the adjustments needed now, in order to help diminish some of the worst effects of these eventualities. What is needed is a willing coalition of ordinary citizens, of city and county government officials, of the private sector, of state leadership, and eventually (or so we can hope) support and encouragement at the federal—and the international—level, to make the kinds of changes that are needed.

This is a tall order, especially in today’s hyper-partisan atmosphere. But in the end, the consequences of doing nothing may be too terrible not to contemplate.








  1. Paul, a great article! The key is education which is under attack by this present administration, as you know. You and I grew up in a generation that believed in teaching its children science, math, civics, the importance of reading and best of all critical thinking. Sadly, these are not stressed in our public schools. An uneducated population is easily controlled and gullible to “alternative facts”. The future looks bleak for the near future, but hopefully the millennials will rise up and save the planet.
