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.

Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30. 3 million km2 (11. 7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area. With 1. 3 billion people as of 2018, it accounts for about 16% of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19. 7, when the worldwide median age was 30. 4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita, in part due to geographic impediments, legacies of European colonization in Africa and the Cold War, predatory/neo-colonialistic activities by Western nations and China, and undemocratic rule and deleterious policies. Despite this low concentration of wealth, recent economic expansion and the large and young population make Africa an important economic market in the broader global context.
