HISTORY OF LIFE
THE AGE OF MAN
The first men were plant gatherers and animal hunters and differed little in life style from other herbivorous and the carnivorous animals around them. They had sufficient intellect to devise tools and weapons and a social organization that made hunting and food gathering more efficient. Neither of these things, however, made any serious impact on the environment.
The first great change in their life style came when, instead of hunting and gathering animals and plants they brought them together and looked after them in a single location. This eliminated the element of danger present in hunting and reduced the probability of starvation, as there was no longer the possibility of returning empty-handed from a foraging expedition. It was the beginning of agriculture.
The evolution of man can be traced from an ape-like ancestor through hominids such as Australopithecus and early members of his own genus such as Homo erectus. Cro-magnon man, an early form of the species Homo sapiens itself, appeared in Europe towards the end of the Pleistocene ice ages. Man's skull developed from a massive structure containing a small brain into one of lighter bones encasing a large cerebral cavity. Man's large brain gave him the power of conscious thought and separated him from the rest of the animal kingdom.
At first the areas under cultivation were small and relatively insignificant. However, the improvements to early man's way of life were so dramatic that his populations increased markedly and more and more land had to be cleared of its natural vegetation to make room for crops and grazing animals.
As man's ingenuity and tool-making ability grew, he invented industrial processes that could produce tools with greater speed and less trouble than before. This inevitably involved heat, and forests were cut down to supply wood and mountainsides were dug away to reach coal to provide fuel. Within a few thousand years the landscape of the earth was changed out of all recognition.
Man's knowledge grew, most significantly in the field of medical science. Accidents and diseases that help to keep natural populations in check were overcome or reduced in their effects by man's endeavours. Genetic defects that, in the wild, would have proved fatal and would have been eliminated by natural selection were perpetuated because their possessors were allowed to live and reproduce. World population increased exponentially and hardly a region of the earth's surface remained untouched by man.
The ultimate effect was that, whereas other animals change and adapt through the slow process of evolution to fit into their environment, man was able to change his environment to suit his current needs, reaping a short-term advantage in the process. Living outside evolution each stage in his rapid cultural development was passed on to the next generation, not through his genes but by learning. Although he avoided the unpleasant effects of natural selection, he also did without its long-term benefits and in short called a halt to evolution as it applied to himself. The result was a world overburdened by a population of beings unable to survive without their own conscious intervention, a world given over to the essential needs of man, a world poisoned by his waste.
Ultimately the earth could no longer supply the raw materials needed for man's agriculture, industry or medicine, and as shortage of supply caused the collapse of one structure after another, his whole complex and interlocking social and technological edifice crumbled. Man, no longer able to adapt, rushed uncontrollably to his inevitable extinction.
With the dominant life form gone the animal world entered a period of evolutionary chaos that lasted tens of thousands of years. However, man's extinction provided the impetus for the formation of many new species of animals and his disappearance was of fundamental importance in shaping the world that has emerged 50 million years later.
Basically the human race started off as hunter and gathers, which had minimum impact on the environment. Then we invented agriculture, which caused our impact on the environment to increase. We started to damage the environment in profound ways when we invented agriculture. And then we invented industrialism.
With the use of fossil fuels,we were able to increase the productivity of products. And we were able to increase our consumption of other natural resources with fossil fuels. World population also increases as a result of fossil fuels and advances in medical technology. The world population becomes so large that it overburdens the Earth. There is simply too many human beings on this planet. Eventually the population grows to such a large number that it collapses under its own weight, as the resources man depends on for his industry, agriculture and medicine are gone from overdepletion. And then the human race faces an extinction level event, wiping off the entire human race.
After mankind becomes extinct, life on Earth goes on without us. Human beings aren't that important. We are just a speck in the history of the Earth. The anthropocene, the area of man, was just a tiny fraction of the history of the Earth.
This is a likely future if we keep on doing business as usual. If we keep on increasing population, this will be the likely outcome of the human race. The human race will become an evolutionary dead-end if we keep on increasing population to the point where the human race eventually becomes extinct because we used up all of the resources on this planet.
No amount of technology and ingenuity can overturn the laws of nature. When we use up all of the resources on this Earth from population overshoot, the consequences is a die off. It is that simple. And this die-off may wipe-off the entire human race.
That's all I have to say. The brief excerpt I showed you is what lies ahead for the human race.
