Environmental Sustainability, Evolution and Natural Selection

Environmental conservation and its sustainability have been increasingly important issue throughout the world. The ecology friendly environment is one of the burning needs of today’s world if we want to sustain the human species and the quality of living on this planet. Although the effects of the human on the environment may not be clearly seen in day to day life, the accumulated impact over the time is quite evident. The ozone layer depletion, rapidly changing weather patterns and rising earth’s temperature are some of the obvious negative impacts caused by humanity.

Conservation of ecological system comes hand in hand with environmental sustainability. There are numerous known and unknown factors which help preserve a sound ecological system of which we human are just a small part. Every part of the ecosystem is equally important for every species in it to live and thrive in harmony, call it environment if you will. The process of evolution supports the fact that the environmental disruption may drive species to extinction. Humans could be responsible for the extinction of the most of the world’s mammals around 14,000 years ago.

Could the Homo-sapiens be responsible for the extinction of twelve other human species which coexisted around the same time?

Likewise, plenty of evidence from the past explains that humans had great impact on environment since the dawn of modern civilization. European colonialism and imperialism caused impacts by treating the nature as mere exploitable resource all around the world. In more recent times, the environment has been greatly affected by the rise of industrialization, with very little sense of nature conservation, sustainable growth and ecological harmony.

Although, the theory of evolution argues that only the fittest can survive in this competitive world, it should not be forgotten that, the competitive world includes nature as well and also for the evolution to take place we should let the environment make the natural selection and not the other way round. We, as conscious, sane and sensible human beings, should highly avoid intervening with the environment and its natural harmony by spreading pesticides, herbicides, chemical wastes and pollutants.

We might be the fittest species on the face of the planet but that surely does not give us right to disrupt the ecological cycles, prevailing here for millennia. Threatening environmental harmony might drive us towards extinction for the nature might choose not to select us after all.

  1. Overshoot is a natural process. Although we do put selection pressures on other organism to cope with the world as it is being changed by humans (in the anthropocene…), the most relevant story is our own story. It is humans who are currently selected to self-regulate. Those human population who fail will become extinct. We certainly do not have it in our genes, but we can make up for that with our cultural evolution. There is hope.
