The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to the Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. The concept of the natural environment can be distinguished as components: Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms, soil, rocks, atmosphere, and natural phenomena that occur within their boundaries and their nature. Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from civilized human actions. Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, and water pollution.

Eastern Europe is the eastern region of Europe. There is no consistent definition of the precise area it covers, partly because the term has a wide range of geopolitical, geographical, ethnic, cultural, and socioeconomic connotations. Russia, located in Eastern Europe, is both the largest and most populous country of Europe, spanning roughly 40% of the continent's total landmass, with over 15% of its total population. According to the Center for Educational Technologies at Wheeling Jesuit University, there are "almost as many definitions of Eastern Europe as there are scholars of the region". A related United Nations paper adds that "every assessment of spatial identities is essentially a social and cultural construct". One definition describes Eastern Europe as a cultural entity: the region lying in Europe with the main characteristics consisting of East Slavic, Greek, Byzantine, Eastern Orthodox, and some Ottoman cultural influences. Another definition was created during the Cold War and used more or less alike with the term Eastern Bloc. A similar definition names the formerly communist European states outside the Soviet Union as Eastern Europe. Such definitions are often seen as outdated but they are still sometimes used for statistical purposes.
