The Bleak Future that Faces us if Current Trends Continue

If current population trends continue . . .  
• The population of the United States will increase to over 600 million by 2080, and in 2150 it will equal China’s present size.
• World population will achieve 14 billion by the year 2075 and 30 billion by 2150.

If current energy trends continue . . .
• By 2015 China will be importing more oil than the United States does that year.
• By 2030 China will be absorbing all available global oil exports, leaving none for the US or Europe.
• In just 8 years China will be burning as much coal as the entire world uses today.
• Natural gas will be virtually free in the US by 2015.
• Officially assessed US natural gas reserves will be exhausted by 2025.

If current economic trends continue . . .
• China’s economy will be 8 times as big as it is today by 2040.
• China’s economy will surpass the size of the present global economy before 2050.
• The US federal debt will double—from $14 trillion to $28 trillion—by 2022.
• In 2072, the federal debt will amount to $896 trillion, or $1,629,091 for each American (assuming a US population then of 550 million).
• By the end of the century, each American will “owe” over a billion dollars.
• Thanks to the doubling of US households living on less than $2 per person per day between 1996 and 2011, in 150 years there will be about 1.5 billion Americans living on practically no income.
• The number of billionaires in the world (having grown from 793 to 1210 in just two years, from 2009 to 2011) will equal the world population in only 70 years. (Given the previous trend, this is especially gratifying news: since the rate of growth in the number of billionaires in the world exceeds the rate of growth in extreme poverty in the US, this means each American will become a billionaire before his or her grandchildren plunge into desperate poverty).

If current technology trends continue . . .
• Thanks to Moore’s Law (whereby the number of transistors that can be placed inexpensively on an integrated circuit doubles approximately every two years), within 20 years transistors will be the size of an atom, and after another generation or so, “transistors” (if they can be called such, at that point) they will be the size of an electron.
• It will eventually be possible to download into a computer all the memories and even the personality of a human individual.

If current environmental trends continue . . .
• Due to the decades-long decline in male sperm counts, apparently caused by a proliferation of environmental hydrocarbon-based, estrogen-mimicking pollutants, the human species will go extinct sometime within the next two centuries.
• With China’s coal consumption climbing at 8 percent per year, annual global greenhouse gas emissions will skyrocket, setting off multiple strong self-reinforcing environmental feedbacks that will ensure the melting of all polar ice, the death of the oceans, and the collapse of most agricultural production on the planet.

Trends do tend to continue for a while; otherwise they wouldn’t be trends. But sometimes trends in different areas work against each other and end up canceling each other out. In fact, all trends (except perhaps the expansion of the universe) eventually reach limits and stall out or reverse themselves.

Because projecting future magnitudes according to current trends requires relatively simple math, and because doing so sometimes enables analysts to make accurate short-term forecasts of things like population, sales volumes, and commodity prices, trend watching can confer a sense of mystical power. We can predict the future—and maybe even profit by doing so!

But, as Benjamin Disraeli famously said, “There are three kinds of lies: lies, damned lies, and statistics.” Indeed, projecting existing statistical trends out over long time periods often leads to absurd conclusions. Hence the necessity, when observing trends, of knowing (or at least being able to guess successfully) which ones are important or trivial, and which ones are likely to persist longer than others. A skilful trend watcher will note not only the rate of change in a given magnitude, but the rate of change to the rate of change: for example, while world population is growing at a rate of about 1.1 percent annually, its pace of growth has diminished in recent years, and that’s an important factor in forecasting world population for, say, 2050 or 2100.

In addition to generalized critical thinking skills, citizens need the ability to assess statistics-based claims in order to arm themselves against people with a political axe to be honed, or buck to be made, by hawking a particular trend. Unfortunately, policy makers don’t always have (or use) these skills, and so it’s common to encounter unrealistic assumptions about our future based on trends unlikely to continue for long. Often this is not just a matter of sloppy thinking: policy makers want certain trends to go on—because if they didn’t, there’d be hell to pay.

The obvious example is economic growth. Government officials assume (based on trends over the past few decades) that national economies will continue to expand forever, just as transportation planners assume that automobile traffic will always proliferate. Therefore more highways and suburbs are justified, and more public debt—because of course tax revenues will increase. Never mind that, in the US, there’s little basis for further real economic growth in light of debt levels and demography; or that vehicle miles traveled have actually declined significantly in recent years. Those are inconvenient trends that politicians and road-builders hope will simply go away. But will they? Certainly not if global oil supplies continue to tighten (another inconvenient trend): scarce oil will discourage both economic growth and driving.

Because business-as-usual assumptions are based on numbers, they appear both reassuring and authoritative. But which numbers matter?

More and more numbers look alarming. There’s a trend—a trend of trends! It might be difficult to total up the disturbing (versus reassuring) trends in the world and determine the rate of change in abundance of the latter versus the former. But it’s hard to avoid the subjective impression that more trends these days point to frightful or absurd outcomes.

Reality check: A snapshot of trends in the year 1200 would have shown temporary rapid change in a few variables (for example, in localized numbers of deaths from famine), but most rates of change were comparatively negligible. Not so in 2012, when rates of change in resource availability, species abundance, greenhouse gas concentrations, and debt levels yield doubling times measured in decades or, in some cases, mere years. Absurdity—or calamity—arrives fast at those rates.

If many key rates of change are accelerating, does this mean we are approaching some sort of historic discontinuity? If so, when will it arrive? What will it actually look and feel like? We can only guess; it all depends on which trends prove decisive. We’d all like to believe the world-weary French proverb, Plus ça change, plus c’est la même chose (“The more things change, the more they stay the same”). But what if the less witty formulation is truer: “The more things change, the more they change”?

Amid this uncertainty, there are two things we probably can conclude with some significant degree of confidence. First: many important current trends won’t continue for long. Second: if you like change, this is a great time to be alive.

    Less than 2% of the land mass in the US is developed. If all the people on Earth moved to Texas, each family would have a nice piece of property to live on, to even grow their own food and be self-sustaining (source: http://groups.google.com/group/alt.conspiracy/msg/02a750bd39257d96)

    We all know that central bankers use their endless fiat money to pay many (!!!) people, who in turn perpetuate the myth that overpopulation is going to destroy the planet. This article above is just one of these endless efforts.

    Central bankers seek total power over humanity, at all costs. Only ignorance will allow this to happen. Intelligent individuals who serve their own lower instincts will help perpetuate ignorance; they will take the money and write whatever the central bankers want them to write.

    Research UN Agenda 21 and the Tavistock Institute of you would like more information on the level of central banker manipulation that is going on now.

    Wow De Captain, your post is incredibly off the mark.

    First of all, by my simple calculations, if every person on earth were crammed into Texas, each person would have a 30 foot by 30 foot area to themself. People would be forced to live in lakes, on top of mountains, cliff sides, and whatnot to achieve this. There would be no space for roads, parks, sidewalks, farms, mines, oil rigs, or shopping malls if this were a reality. So no, everyone on earth couldn't fit into Texas, and there is NO WAY it would be self-sustaining for more than a week or two.

    As for your assertion that only 2% of USA land is developed... WHAT? 2% of land is urban, while 25% is pasture, 21% is crop, not to mention a vast swath of the country is used for forestry, mining, drilling, etc. which allows the majority of the populace to inhabit only 2% of the country in cities (source: http://www.ers.usda.gov/Publications/EIB14/). Look at a satellite image of the earth and tell me only 2% is being used.

    Overpopulation is a real problem. In fact, it is THE real problem. Most other issues (resource depletion, food shortages, many conflicts, environmental degradation, pollution, global warming) are just by products of overpopulation.

    There seems to be a disconnect between population trends and sperm count trend.

    So we are both going to overpopulate the planet and die out from lack of ability to reproduce and it's all going to happen at the same time.

    I think you've made an error in your pop growth rate trend... that is you are assuming an unchanging growth rate when the trend has been a steadily decreasing growth rate since the 1970s. Indeed in Western Europe and North America population growth would be negative if not for immigration. Russia is already experiencing negative population growth (no one want to immigrate!).

    There is a very strong likelihood that the world population will never reach 14 billion. Current UN projections show it topping out at around 9-12 billion.
