Earth is everybodys home and nobody likes to live in a dirty home.

For e.g. several million people worked with asbestos during and after world war two.

Ironically, industrialization threatens to disable the basic environment of human race, posing what may be the greatest health hazard of all time. Underlying todays environment decay is the globalization of capitalism which continues to push for economic growth. Earth cannot withstand such an onslaught. Global economic production creates global pollution, and faster paced production means faster paced destruction of our environment. In short the message implies as to “Growth at any cost”. Industrial growth did come, but at a high cost to the natural environment. Burning fossil fuels to run factories, motorized vehicles and power plant have been especially harmful. Motor vehicles produce high levels of Carbon monoxide (CO) and major source of hydrocarbons (HC) and nitrogen oxide (NO). Whereas fuel combustion in stationary sources such as residential, commercial and industrial heating and cooling and coal power plants, the dominant sources is Sulfur Dioxide.
Carbon dioxide is
