Overpopulation is a term that refers to a condition by which the population density enlarges to a limit that provokes the environmental deterioration, a remarkable decline in the quality of life, or a population collapse. The term population density denotes the number of inhabitants dwelling in a specific area, for example: 100 inhabitants per square Kilometer. The impact of human populations on the environment has been severe. Some animal species have been extinguished or forced to live in inhospitable regions by the advance of urban areas; pollution is a problem that is increasing gradually because we are using more cars. Emerging countries industrialization is not paying attention to environmental issues because of the feeding demands of their ever-growing populations. The human overpopulation has been credited to diverse factors, as the increment in life-span, the absence of natural enemies, the improvement in the quality of life, and the accessibility to get better goods. Every year, more than 81 million people add the world-wide population. Every 10 years almost one billion inhabitants are added to the world’s population. TOP OF PAGE ^^ CURRENT EFFECTS OF OVERPOPULATION Due to the opening out of human settings, 16 million hectares of forest are chopped down each year. The accelerated growth of the human populations has propitiated the destruction of natural habitats of many species. People are invading the habitats of those species, replacing them to inhospitable places and condemning the native species to the extinction. The speed of extinction of plants and animals attributable to human activities is 10,000 times faster than the natural quotient. About 5 million people die every year from illnesses associated to organic wastes. Too dense human communities produce tons of solid wastes (organic and inorganic waste) daily, consume large quantities of energy and emit more pollutants to the environment. Water necessities will increase to 20% by 2025. Approximately, one half of wetlands around the world have been lost since 1900. In USA, consumption of materials (wood, metals, synthetics, etc.) has grown
