Environmental Effects of Urbanization. Urban populations interact with their environment. Urban people change their environment through their consumption of food, energy, water, and land. And in turn, the polluted urban environment affects the health and quality of life of the urban population.
The Cold War developed in the Soviet Union, Europe, and the United States due, in large part, to the competition over the arms race and over scientific advancement during the 1970s and 1980s. The Soviet Union pursued communist ideas while the United States and Western Europe followed democratic principles. The Cold War developed as each built up it's military to protect and advance it's own ideology.
It is false that Communism was the dominant economic force of the twentieth century, although it certainly overtook a great deal of territory. Capitalism was still overall dominant.
