Overconsumption of natural resources has been putting undue pressure on earth as a planet. Human habitats are being plundered of their natural resources base. Air and water pollution is rampant in all industrialized cities of the world. PPM (particulate matter per cubic meter of air) is alarmingly high and is no more fit for human breathing. The COD, BOD levels in freshwater streams are quite low for the survival of plant and animal life in waters. The soils are being badly damaged by excessive cropping. The precious animal and plant species are endangered. The CO2 level in the atmosphere is alarmingly high. Results are the global warming and climate change.&nbsp.
