Milestone math adds up to trouble

When the new American is born or arrives across the border sometime today to push the U.S. population to 300 million, don't expect 83-year-old Albert Bartlett to party like it's 1967.
For one thing, he's pretty sure the Census Bureau's estimate for when the population ticker hit the 300 million mark is late by a year or more. For another, he's watched what has happened since the population hit 200 million 39 years ago, and he sees no cause to celebrate.
Never mind what the get-rich-quick crowd says, he said. "Growth never pays for itself." By every measure - environmental, economic, quality of life - it is a costly proposition.
It all comes down to arithmetic, said the retired professor of physics at the University of Colorado-Boulder. Those who equate growth with prosperity have sold our math-phobic culture a dangerous lie.
He offers the commonly held solution to the problem of a burgeoning number of retirees as an example.
Increasing immigration rates and birthrates to provide additional young workers to support the elderly only exacerbates that problem in the future, he said. "It's like a Ponzi scheme."
The benefits of job-creation programs are another myth. "If creating jobs really lowered unemployment, here in Colorado we would have reached negative unemployment (full employment with excess jobs) decades ago," he said.
Instead, whenever jobs are created, people move here to fill them. More houses, schools, roads and public services are needed to serve them, and the unemployment rate continues mostly unchanged.
"If growth really was paying for itself, the state would be in great financial circumstances after the go-go 1990s," he said. "Instead, it's practically bankrupt."
The effects of tax-limitation measures offer no excuse, he said. Voters endorsed those policies because "they were rebelling against the cost of growth and the higher taxes needed to support it."
But in his view, the scariest deficit looms in the natural world.
Among the unsustainable policies sneaking up on Americans is the depletion of global oil reserves.
The concept of peak oil - when the production of oil worldwide reaches its maximum and begins its inevitable decline - "has been in the literature since 1956," said Bartlett. Scientists predict peak oil will occur this decade, and "this is serious."
It's only the non-scientists in the government who have ignored it, he said. The U.S. Department of Energy "has been headed by hacks.
"What we need in this country is a conservative policy on energy," Bartlett insisted. "We need to save the world's oil for future generations. But instead, we've had a profoundly liberal policy" of unrestrained consumption.
The same irresponsible approach has been applied to managing water resources, land and natural gas, he said.
With population growth unchecked and profligate overconsumption of natural resources, food and energy inevitably will become scarce and expensive.
Computer models actually predict a global economic collapse by the middle of this century, he said, "with an enormous die-off" of the world's population.
Bartlett is convinced that the only way to achieve a sustainable society is to have zero population growth and immediate reductions in per-capita energy consumption globally.
Not that he thinks that's really happening.
On the contrary, here in the U.S., per capita energy consumption has exploded in the past decade, and the population is expected to hit 400 million around 2040.
"There's no limit in sight," he said.
Still, even for Bartlett, who has done the math and knows a looming planetary crisis when he sees one, there is hope.
"Humans remain quite unpredictable," he said.
Which is to say that while we all know what they usually do when they're cold, hungry and stuck at home during a disaster, maybe someday they'll surprise everybody ... and use protection.
World Scientists' Warning to Humanity
by Jay Hanson on 18 November 1992 on www.worldtrans.org
for the Union of Concerned Scientists, 96 Church Street, Cambridge, MA 02238
Human beings and the natural world are on a collision course. Human activities inflict harsh and often irreversible damage on the environment and on critical resources. If not checked, many of our current practices put at serious risk the future that we wish for human society and the plant and animal kingdoms, and may so alter the living world that it will be unable to sustain life in the manner that we know. Fundamental changes are urgent if we are to avoid the collision our present course will bring about.
The environment is suffering critical stress:
Stratospheric ozone depletion threatens us with enhanced ultra-violet radiation at the earth's surface, which can be damaging or lethal to many life forms. Air pollution near ground level, and acid precipitation, are already causing widespread injury to humans, forests and crops.
Heedless exploitation of depletable ground water supplies endangers food production and other essential human systems. Heavy demands on the world's surface waters have resulted in serious shortages in some 80 countries, containing 40% of the world's population. Pollution of rivers, lakes and ground water further limits the supply.
Destructive pressure on the oceans is severe, particularly in the coastal regions which produce most of the world's food fish. The total marine catch is now at or above the estimated maximum sustainable yield. Some fisheries have already shown signs of collapse. Rivers carrying heavy burdens of eroded soil into the seas also carry industrial, municipal, agricultural, and livestock waste -- some of it toxic.
Loss of soil productivity, which is causing extensive Land abandonment, is a widespread byproduct of current practices in agriculture and animal husbandry. Since 1945, 11% of the earth's vegetated surface has been degraded -- an area larger than India and China combined -- and per capita food production in many parts of the world is decreasing.
Tropical rain forests, as well as tropical and temperate dry forests, are being destroyed rapidly. At present rates, some critical forest types will be gone in a few years and most of the tropical rain forest will be gone before the end of the next century. With them will go large numbers of plant and animal species.
The irreversible loss of species, which by 2100 may reach one third of all species now living, is especially serious. We are losing the potential they hold for providing medicinal and other benefits, and the contribution that genetic diversity of life forms gives to the robustness of the world's biological systems and to the astonishing beauty of the earth itself.
Much of this damage is irreversible on a scale of centuries or permanent. Other processes appear to pose additional threats. Increasing levels of gases in the atmosphere from human activities, including carbon dioxide released from fossil fuel burning and from deforestation, may alter climate on a global scale. Predictions of global warming are still uncertain -- with projected effects ranging from tolerable to very severe -- but the potential risks are very great.
Our massive tampering with the world's interdependent web of life -- coupled with the environmental damage inflicted by deforestation, species loss, and climate change -- could trigger widespread adverse effects, including unpredictable collapses of critical biological systems whose interactions and dynamics we only imperfectly understand.
Uncertainty over the extent of these effects cannot excuse complacency or delay in facing the threat.
The earth is finite. Its ability to absorb wastes and destructive effluent is finite. Its ability to provide food and energy is finite. Its ability to provide for growing numbers of people is finite. And we are fast approaching many of the earth's limits. Current economic practices which damage the environment, in both developed and underdeveloped nations, cannot be continued without the risk that vital global systems will be damaged beyond repair.
Pressures resulting from unrestrained population growth put demands on the natural world that can overwhelm any efforts to achieve a sustainable future. If we are to halt the destruction of our environment, we must accept limits to that growth. A World Bank estimate indicates that world population will not stabilize at less than 12.4 billion, while the United Nations concludes that the eventual total could reach 14 billion, a near tripling of today's 5.4 billion. But, even at this moment, one person in five lives in absolute poverty without enough to eat, and one in ten suffers serious malnutrition.
No more than one or a few decades remain before the chance to avert the threats we now confront will be lost and the prospects for humanity immeasurably diminished.
We the undersigned, senior members of the world's scientific community, hereby warn all humanity of what lies ahead. A great change in our stewardship of the earth and the life on it, is required, if vast human misery is to be avoided and our global home on this planet is not to be irretrievably mutilated.
What we must do
Five inextricably linked areas must be addressed simultaneously:
1. We must bring environmentally damaging activities under control to restore and protect the integrity of the earth's systems we depend on.
We must, for example, move away from fossil fuels to more benign, inexhaustible energy sources to cut greenhouse gas emissions and the pollution of our air and water. Priority must be given to the development of energy sources matched to third world needs small scale and relatively easy to implement.
We must halt deforestation, injury to and loss of agricultural land, and the loss of terrestrial and marine plant and animal species.
2. We must manage resources crucial to human welfare more effectively.
We must give high priority to efficient use of energy, water, and other materials, including expansion of conservation and recycling.
3. We must stabilize population. This will be possible only if all nations recognize that it requires improved social and economic conditions, and the adoption of effective, voluntary family planning.
4. We must reduce and eventually eliminate poverty.
5. We must ensure sexual equality, and guarantee women control over their own reproductive decisions.
The developed nations are the largest polluters in the world today. They must greatly reduce their overconsumption, if we are to reduce pressures on resources and the global environment. The developed nations have the obligation to provide aid and support to developing nations, because only the developed nations have the financial resources and the technical skills for these tasks.
Acting on this recognition is not altruism, but enlightened self-interest: whether industrialized or not, we all have but one lifeboat. No nation can escape from injury when global biological systems are damaged. No nation can escape from conflicts over increasingly scarce resources. In addition, environmental and economic instabilities will cause mass migrations with incalculable consequences for developed and undeveloped nations alike.
Developing nations must realize that environmental damage is one of the gravest threats they face, and that attempts to blunt it will be overwhelmed if their populations go unchecked. The greatest peril is to become trapped in spirals of environmental decline, poverty, and unrest, leading to social, economic and environmental collapse.
Success in this global endeavor will require a great reduction in violence and war. Resources now devoted to the preparation and conduct of war -- amounting to over $1 trillion annually -- will be badly needed in the new tasks and should be diverted to the new challenges.
A new ethic is required -- a new attitude towards discharging our responsibility for caring for ourselves and for the earth. We must recognize the earth's limited capacity to provide for us. We must recognize its fragility. We must no longer allow it to be ravaged. This ethic must motivate a great movement, convince reluctant leaders and reluctant governments and reluctant peoples themselves to effect the needed changes.
The scientists issuing this warning hope that our message will reach and affect people everywhere. We need the help of many.
We require the help of the world community of scientists -- natural, social, economic, political;
We require the help of the world's business and industrial leaders;
We require the help of the worlds religious leaders; and
We require the help of the world's peoples.
We call on all to join us in this task.
