Introduction



most important feature is that the natural balance in the ecosystem is maintained at any given point in time and corresponds to the soil and climate.This balance can be disrupted due to the introduction of new species, the sudden disappearance of some animals, natural disasters or man-made disasters.The ecological balance - a continuously changing ratio of the resource - environmental opportunities and economic needs.It should also take into account the human population and development affect the ecological balance.

natural ecological balance



ecological balance is maintained complex relationships betwe
en living organisms and environmental conditions, the relationship between the different types and relationships within the species itself.Conflicts may occur in the struggle for resource consumption.And if the amount of resources is limited or insufficient, there is a competition for survival.The main type of relationship - it is eating one type of entity to another.Examples are the predators - strong animals eat other weaker.Some species of animals are herbivores and eat plants.There are also plants predators that feed on living organisms.As a result, long-term processes such interaction may impair the ecological balance.May occur with complete destruction of the landscape or very prolonged loss of biological productivity.

human impact on nature



negatively can affect and negligent attitude of man to nature.In the name of development, we cut down the forests, expanding paved land, thereby killing the vegetation.Water balance also affects the soil environment.Urbanization requires a huge amount of resources to feed the urban population and to support the industry.Often you need to drill deep wells or redirect the water in more distant places.

War also causes environmental losses.For example, carpet bombing during the Vietnam War led to a loss of habitat for many species.

Increasing the area of ​​the road surface reduces the amount of water vapor leads to the contamination of groundwater, when for cleaning of roads ice salt is used.

Conclusion



There are many examples of how the increase in human population impact on the ecosystem.Over the last 1,000 years of human impact on the environment have increased, mainly due to deforestation and an increase in pasture.

Such problems have intensified in recent years with unprecedented population growth and urbanization, resulting in an increase of anthropogenic impact not only on individual species but also on the entire ecosystem.

Rapid development has led to many unwanted results.Many plant and animal species are disappearing, and the ancient ecosystems are adversely affected.
