Human activity over the past few millennia has been able to influence the Earth. As reality shows, it becomes the only source of pollution in the environment. Because of what is observed: a decrease in soil fertility, desertification and land degradation, deterioration in air and water quality, the disappearance of species and ecosystems. In addition, there is a negative impact of the environment on human health and life expectancy. According to modern statistics, more than 80% of diseases are related to what we breathe, what water we drink and what soil we walk on. Consider this in more detail.
The negative impact of the environment on human health is due to industrial enterprises located near residential areas. As a rule, these are powerful sources of harmful emissions into the atmosphere.
Various solid and gaseous substances enter the air daily. We are talking about carbon oxides, sulfur, nitrogen, hydrocarbons, lead compounds, dust, chromium, asbestos, which can have a toxic effect on the body ( respiratory organs, mucous membranes, eyesight and smell).
The effect of environmental pollution on human health contributes to the deterioration of the general condition. As a result, there is bronchitis, asthma, nausea, headaches and a feeling of weakness, and disability is reduced.
The water balance of the Earth also has a negative effect. Diseases that are transmitted through contaminated sources cause deterioration, and often death. As a rule, the most dangerous are ponds, lakes and rivers, in which pathogens and viruses actively propagate.
Contaminated drinking water, which comes from the aqueduct, contributes to the development of cardiovascular and renal pathologies in humans, and the appearance of various diseases.
Consequently, as a result of the fact that a person constantly creates a large number of amenities for his life, scientific progress "does not stand still." Due to the implementation of most of his achievements, a whole range of harmful and unfavorable factors for life has appeared. We are talking about increased levels of radiation, toxic substances, combustible fire hazardous materials and noise.
In addition, psychological effects on humans can be noted . For example, due to the fact that large settlements are saturated with cars, not only the negative impact of transport on the environment is carried out, but also stress and overwork appears.
The influence of the environment on human health occurs through soil, the sources of pollution of which are enterprises and residential buildings. Due to human activity, not only chemical (mercury, lead, arsenic, and so on) come into it, but also organic compounds. From the soil they penetrate into groundwater, which is absorbed by plants, and then through plants, meat and milk enter the body.
So it turns out that the influence of the environment on human health, as a habitat, is negative.
