The Anthropogenic Factor as a Driver of Ecosystem Changes

Abstract

Throughout history of life, natural events have shaped ecosystems until the human species began to overwhelmingly conquer and exploit this planet. Humans are profoundly altering ecosystems and the natural course of evolution, posing a serious threat to the future of life on our planet. The term "anthropogenic factor" refers to the influence of human actions and population growth on ecosystem structure and dynamics. In light of this, ecosystems can be classified into two categories: (i) natural ecosystems, which remain unchanged by human intervention, and (ii) intervened ecosystems, which have been influenced by the anthropogenic factors. Intervened ecosystems can be further categorized into three types: human-altered ecosystems, human-engineered ecosystems, and urban ecosystems. There is another category of ecosystems, the disappeared ecosystems, whose disappearance may be due to natural catastrophe or human intervention. The disappearance of an ecosystem is a biological tragedy, but it can also represent a new opportunity for life. For the sustainability of the planet as a source of life and to ensure a future for our species in harmony with nature, we need to achieve a sustainable balance between the development and well-being of all human beings, the population growth, the use of the services provided by ecosystems and the preservation of wild nature.
