in recent years have increasingly heard the word "poor environmental conditions", "ecological imbalance", "ecological disaster."Before you argue, if the world faces such a catastrophe, you need to figure out what represents the concept of "ecological balance".Despite the fact that the term was first introduced back in high school, many badly imagine the meaning of this phrase.
Environmental dictionaries explain that the ecological balance - the ratio (both qualitative and quantitative) of all natural processes, environmental components and factors of human activities that provide long-term and sustainable existence biogeocoenose.Biogeocoenosis - is a holistic system, consisting of a complex of plants, animals and other living organisms, tightly interconnected abiotic factors (atmosphere, environment, geological structures, lighting, climate, etc.)
In other words, the ecological balance - athe relative stability of biological processes, climate, community living organisms peculiar to a specific territory.
sustainable ecosystem provides a combination of autotrophic and heterotrophic.The first (they are called producers) - are organisms capable of processing inorganic substances into organic compounds.Heterotrophs for their livelihoods need these organic products.Such organisms are also called by consumers and decomposers.
ecological balance can be measured.Generally considered to be a measure of the diversity of species and their sustainability.
If the changes go beyond the usual environmental standards, there is a violation of the ecological balance.Its result - a sharp decline of some species and the reproduction of others.An example of an environmental catastrophe: the story of the extermination of sparrows in China or reproduction of rabbits in Australia.Illiterate human intervention in these cases resulted in the death of the rivers, the disappearance of many species of animals.
disturb the ecological balance of the gas composition of the atmosphere may be (as dependent and independent of human activity), water pollution, global pollution.
The most common balance is disturbed because of human activities.
man takes more land for their activities, forcing living organisms to their usual habitat.
development of industry contributes to the depletion of natural resources, polluting growth of cities, natural water bodies.
ecological imbalance in the community, some scientists believe, can be a real "end of the world."Their example is the Aral Sea, which is a result of human activity from the fourth largest water body in the world turned into fetid sewers.
Other scientists are not so pessimistic, they believe that the change in environmental conditions does not lead to disruption and a change in the ecological system, forcing people and animals to adapt to new conditions.But even the experts have no doubt: environmental pollution can lead to the fact that a person is out of the system, where it can survive.
To avoid this, it is necessary from early childhood to raise environmental awareness.It is not too difficult.The conscious relationship with nature starts small.If a child learns not to break branches, do not trample on the lawns and did not destroy the grass, then as an adult, he can at least think about how much harm it brings the activities of the outside world.And the one who knows how to think, never destroy your own home, do not destroy the world they live in his children.
