Many people predict that by the year 2050, the world population will reach 9 billion. Human population growth is the number one threat to the world's environment. The cities grow larger and larger as the population is increasing rapidly, the natural land around them is being turned into homes and office buildings. Each person requires energy, space and water to survive, which results in environmental losses. The affluence would results in a larger amount of resources consumptions.
