a part of the natural environment that provides conditions for balance, purity and stability, guarantees the continuity of healthy life and the preservation of the health of people and other living organisms. It is not limited to the presence of natural elements (air, water, soil, plants, animals), but rather to the quality of these elements and the extent to which they are free of contaminants and hazards that can threaten life or adversely affect the well-being of organisms. The main characteristics of a healthy natural environment are:
1) Clean air: the presence of air that is free of chemical pollutants and harmful particles, which ensures respiratory health and disease prevention.
2) Fresh drinking water: water that is free of germs and toxic substances, representing a safe source for drinking, irrigation, and industry.
3) Fertile clean soil: capable of producing food without contamination by chemicals, radiation, or heavy metals.
4) Balanced biodiversity: the presence of a variety of living organisms (plants, animals, microorganisms) ensures the stability of the ecosystem and prevents the violation of the ecological balance.
5) Temperate and relatively stable climate: provides adaptation and natural life away from abrupt climate changes that cause disasters.
