The human mind is our fundamental resource
– J.F.Kennedy, 20-02-1961
After the last Ice Age rising sea levels flooded the land bridge between Tasmania and Australia and effectively separated the islanders from the mainland. When Abel Tasman discovered the island 8000 years later, five thousand Aborigines were living there. Isolated, they had not only missed the progress of the mainland, but they had collectively lost knowledge. They did not use bone tools anymore, but made their tools of stone once again and they did not wear clothes, but rubbed their bodies with seal fat to keep warm. A collective of five thousand people was unable to maintain their level of knowledge, let alone be able to move it forward: technological regression.
Malthusian Catastrophe, AKA This time it’s different
In 1798 Thomas Malthus wrote his Essay on the Principle of Population and the Malthusian school of thought was born; population growth is exponential, Earth’s resources are limited and one of these days this equation will run amuck evoking a catastrophe of enormous proportions. Since then every era has had his envisioned limits and its intellectuals seeing the end of progress because of them. In 1865 William Jevons predicted in The Coal Question Peak Coal. He foresaw the end of progress and stated “I must point out the painful fact that such a rate of growth will before long render our consumption of coal comparable with the total supply. In the increasing depth and difficulty of coal mining we shall meet that vague, but inevitable boundary that will stop our progress.” Paul Ehrlich visioned starvation a hundred years later, stating “The battle to feed all of humanity is over. In the 1970s and 1980s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now. At this late date nothing can prevent a substantial increase in the world death rate.” (from: Population Bomb, 1971). England had Peak Coal, but progress did not stop there and Paul Ehrlich’s book just got its first print and the Green Revolution was well underway, the percentage of malnourished people shrank from 37% in 1970 to 17% in 2007 even as the population of the World doubled.
Nowadays, concern about overpopulation is the intellectual norm. Supposedly the Earth is not able to sustain this many people, let alone an even bigger population. And if Peak Oil will not be our end, surely the use of that oil and the carbon emitted will. But the opposite was true in the past, the larger the population, the better we all had it. What makes this time different? Why would the envisioned limits really be the constraint this time?
The more, the merrier
Since Malthus published his book the world population showed a seven fold increase. In the meantime quality of life made huge strides forward. In Indur Goklany’s excellent Improving State of the World a wealth of data is used to show that the human condition improved tremendously the last few centuries. In the face of all the doomsayers’ predictions nearly every human related measurable parameter has improved and is in better shape than ever. Healthy longevity, food availability, child mortality, maternal mortality, mobility, illiteracy, poverty, child labour, amount of worked hours, suffrage and freedom; all showed massive worldwide improvements. Recently even air and water quality have been improving in the developed world. Also forests and nature reserves have been growing, with many animals flourishing again, this in contrast with the popular opinion that economic growth necessarily comes at the cost of the environment. In the meanwhile, prices of resources become ever cheaper or put differently, we use an ever smaller portion of our income to buy energy, food, water and metals.
Limits of planet Earth
The limits of planet Earth are not absolute; they are solely constraint by the reigning paradigm. Wood, peat, coal, but also oxes, horses, wind and water energy (in the Middle Ages) were all used in their paradigm to their absolute maximum, than they were substituted by a new energy source through innovation and progress continued robustly. By definition one cannot see beyond your paradigm, which provides a sense of finiteness to the people living in the paradigm. This feeling is totally unjustified when looking at the facts. Of all energy circulating on planet Earth, we only use a tiny fraction. In fact, if we compare the World’s energy consumption with the energy the Earth receives from the sun alone, we only use 0.01%, or put differently, each year the Earth receives twice as much energy from the sun as all fossil and uranium reserves put together. It is only a lack of imagination that this energy is not up for grabs.
At this moment the paradigm shift is happening, the solar energy sector is the fastest growing energy sector in the world, doubling output every two years, for thirty five years already, in twenty more years the sun will provide all our energy needs.
Why should we want more people?
Man is a problem solver. We are intrinsically wired to want to solve problems, from puzzles to mathematical problems to curing diseases. The bigger the population the more we can create, build, innovate and solve. The more we can specialize and use our brains as efficiently as possible for ever more complex problems. But also, the more we are, the more music, movies and art we will make. The more Einsteins, Mozarts and Peles we will come to know.
All major problems mankind is facing, problems like cancer, aids, food, water and energy supply and global warming, we will solve sooner with more people than with less. This is because the limits are not defined by the Earth yet, but only by our creativity. In its essence every new person is primarily a problem solver, not a problem. That’s why up to now the bigger the population, the better we all have it and that’s why we are allowed to embrace every new human being with rejoice and not need to fear a growing population. Like the average human being in existence, a new baby will probably be a net problem solver, an enrichment to the lives surrounding it and a contributor to the World’s wealth. In other words, a welcome addition to team human.
The Stone Age didn’t end because we ran out of stones
There are caves in the Netherlands, tens of meters beneath the ground, kilometres long where my ancestors in the Stone Age were digging for pieces of flint. Possibly they were also afraid that they would run out of their essential resource, their way of making fire and tools, trapped as they were in their paradigm. Also they would not be able to see the solutions of tomorrow for the problems of today and also they could not presume there was only one resource fundamental for our progress. That resource is the most complex object in the known universe. It is the ultimate resource: our brains and their potential for creativity is infinite.
