For years I have watched the debate over genetically modified organisms (GMO), predominantly food items, with interest but not been sure where the problem was. Recent news articles have given me some new thoughts on the matter and a real cause for concern, however. Current genetic modifications, predominantly created and promoted by Monsanto, make food crops resistant to weed-killing chemicals so that more of those chemicals can be used without harming the crops. The higher yield of those crops is offered as reason enough to use these genetically modified seeds. The GM crops are generally tougher to kill and that, while it has benefits, presents the real problems. Continue reading

A number of studies described in a recent NPR article agree that slightly over 70,000 years ago, after a supervolcano eruption much larger than any we’ve seen in recorded history, total human numbers were reduced to a few thousand or less. Now we find ourselves in a heavily overpopulated situation where we may surpass the Earth’s capacity to provide food and energy within the next few decades, and we need to think ahead as to how to survive the coming period of extreme volatility. Still, there are supervolcanos in the world that are centuries and millennia past their normal eruption cycle, just ready to blow. Surely we are smart enough as a species to think ahead and prepare for such calamities, aren’t we?
I leave this as an open question. It has meaning well beyond the immediate topic. Thanks for reading – Tim
Important Question for your Legislators: Can Growth Continue Indefinitely and, If Not, What Follows It?
Hindsight is golden – no question about that. All through the recent election season I pondered what the right question was to ask legislators and, of course, it hit me days after the election: “Do you think population and economic growth can continue forever and, if not, what do you think will happen when the trend reverses?” This and similar questions should be at the top of everyone’s list, not just today but every day for decades to come.

Food systems are going to be of primary importance as population peaks. If, as the UN says, population will reach more than 9 billion in the 2040’s before beginning a steep decline, the causes of that decline are important to consider today. A historical review of population reductions shows that neither war nor the natural disasters we’ve seen so far make a noticeable difference, but suggests that famine and possibly disease have the potential to make major reductions in the population. Decades ago I expected that we might pollute our world so badly that average lifespans would fall, but there has been some progress on preserving the environment and it appears that energy and food shortages created by overpopulation are bigger concerns. (Of course, the primary concern SHOULD be overpopulation itself, as these other problems are results of it.) If organic food and farming methods are more costly than agribusiness’ methods now, why would they replace the hugely productive methods used to produce most food in the developed world today?

Are we smarter than lemmings? It’s time for humanity to prove how smart we are. We are faced with the biggest crisis we, and perhaps any species on the planet, has ever faced: our own overpopulation. But are we going to continue to grow our numbers until the massive and complicated systems by which we sustain ourselves collapse, essentially “marching off a cliff” as lemmings were once said to do? Or are we smart enough to curb our population growth and find a way to a sustainable world situation? Continue reading
Are we reaching the practical limits of our intelligence as a species? Looking around at our world it seems obvious that we are making huge problems for ourselves by growing faster and more numerous than our environment can sustain. Politically and economically we appear to be functioning more and more in a “thrashing” mode, where our actions are not well-considered or coördinated, the outcomes fail to reflect lasting or meaningful improvements, and we fail to reduce the risks of big problems that are becoming more obvious every day. It seems we need to become smarter about ourselves and our world, and take a more realistic view of our global problems. But what factors are preventing us from doing this, and what improved understanding must we gain to make improvements? We can’t all be experts, but in the United States we all can vote and need to do so intelligently to ensure our leaders are capable of solving the big problems we face. Can we learn and change our thinking and voting in time to avoid ever larger problems in the future? Continue reading
Are the chickens of the population explosion coming home to roost? An Associated Press article today covered the employment situation in the United States, where the addition of 150,000 jobs in the last month barely matched the increase in the population. It occurred to me that these new people in the population will themselves have children someday, and that in the near future we may see the population growth consistently exceeding the addition of jobs by higher and higher margins. This suggests large and increasing numbers of people will be unemployed, and the middle class will be driven into poverty by the simple mathematics of the population explosion. In addition, conservative attacks on unions and public schools means the middle class will be less well educated and increasingly powerless before corporations larger and more powerful than most countries.
