ABSTRACT
The current production and consumption systems across the world have different impacts on the natural systems that sustain life on Earth. Mankind is a part of such constantly evolving systems. The science dealing with the systems sustaining life is ecology, which investigates ecosystems whose basic parts are plants and organisms mostly formed of water and organic materials. These ecosystems permanently change trying to survive using their reproductive and survival strategies. Except in specific situations, the human population is not considered a part of these ecosystems frequently called the life-sustaining systems. Nevertheless, it also fights for survival in the same way as ecosystems by adapting to natural and self-induced impacts appropriately. Under such circumstances, there might be some interrelations between the people-made and natural causes of impacts on particular ecosystems, which have frequently been referred to as environmental problems.
