Population growth Environmental degradation

world population growth in lin-log scale.

the human population on earth expanding rapidly goes hand in hand degradation of environment @ large measures. humanity s appetite needs disarranging environment s natural equilibrium. production industries venting smoke , discharging chemicals polluting water resources. smoke emitted atmosphere holds detrimental gases such carbon monoxide , sulfur dioxide. high levels of pollution in atmosphere form layers absorbed atmosphere. organic compounds such chlorofluorocarbons (cfc’s) have generated unwanted opening in ozone layer, emits higher levels of ultraviolet radiation putting globe @ large threat.

the available fresh water being affected climate being stretched across ever-increasing global population. estimated quarter of global population living in area using more 20% of renewable water supply; water use rise population while water supply being aggravated decreases in streamflow , groundwater caused climate change. though areas may see increase in freshwater supply uneven distribution of precipitation increase, increased use of water supply expected.

an increased population means increased withdrawals water supply domestic, agricultural, , industrial uses, largest of these being agriculture, believed major non-climate driver of environmental change , water deterioration. next 50 years last period of rapid agricultural expansion, larger , wealthier population on time demand more agriculture.

population increase on last 2 decades, @ least in united states, has been accompanied shift increase in urban areas rural areas, concentrates demand water areas, , puts stress on fresh water supply industrial , human contaminants. urbanization causes overcrowding , increasingly unsanitary living conditions, in developing countries, in turn exposes increasingly number of people disease. 79% of world s population in developing countries, lack access sanitary water , sewer systems, giving rises disease , deaths contaminated water , increased numbers of disease-carrying insects.
