Biological pollution of the environment sources, types and examples

Biological pollution of the environment occurs due to anthropogenic impact on the environment. Mostly, various viruses and bacteria enter the biosphere, which worsen the state of ecosystems, affect animal and plant species.

Sources of biological pollution

  • food enterprises;
  • domestic and industrial waste water;
  • garbage dumps and landfills;
  • cemeteries;
  • sewer networks.
  • Various organic compounds, bacteria and microorganisms enter surface and groundwater, penetrate into the atmosphere and soil, spread and damage ecosystems. The threat is caused by pathogens of parasitic diseases and infections. These biological bacteria adversely affect the health of humans and animals, can lead to irreversible consequences.

    Varieties of biological pollution

    Biological pollution at various times contributed to the emergence of epidemics of plague and smallpox, fever in humans and various species of animals and birds. At different times, the danger was and is the following viruses:

  • anthrax;
  • plague;
  • smallpox;
  • Ebola hemorrhagic fever;
  • rinderpest;
  • rice blast;
  • Nepah virus;
  • tularemia;
  • botulinum toxin;
  • chimera virus.
  • These viruses are fatal to humans and animals. As a result, the issue of biological pollution should be raised. If it is not stopped, then some virus can massively and in a short time destroy millions of animals, plants and people so quickly that the threat of chemical or radioactive contamination does not seem so strong.

    Methods of combating biological pollution

    Everything is easier for people: you can get vaccinated against the most terrible viruses. Infection of flora and fauna by various microorganisms and bacteria cannot be controlled. As a preventive measure, high sanitary and epidemiological standards should be observed everywhere. Of particular danger are the inventions of genetic engineering and biotechnology. From laboratories, microorganisms can enter the environment and spread rapidly. Some inventions lead to gene mutations, affect not only the state of the body of specific individuals, but also contribute to the deterioration of reproductive function, as a result of which species of flora and fauna will not be able to renew their numbers. The same goes for the human race. Thus, biological pollution can quickly and massively destroy all life on the planet, including people.
