Rich or Air Pollution?

Rich or Air Pollution?
  Air pollution is a global issue which is the introduction of particulates, biological molecules, or other harmful gases into Earth's atmosphere, leading to disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment.

Air pollution from the industry

  In the majority of people's perspective, this kind of pollution comes from the mankind activities such as burning or car exhaust. However, the truth is that the air pollution result from both anthropogenic or natural sources.

  The air pollution can be divided into two different categories which are chemical pollution and biological contamination. The pollutants in the air also can be classified into anthropogenic and natural aspects. The form of the substance can be solid particles, liquid droplets, and gases.
  In Australia, the mining is a promising industry, and the export ranks the front of the world. And because of the air pollution, there is ozone hole in the air above the Australia. The ozone layer prevents most harmful UVB wavelengths of ultraviolet light form passing through the Earth's atmosphere, observed and projected decreases in ozone generated worldwide concern, leading to adoption of the Montreal Protocol that bans the production of CFCs, halons, and other ozone-depleting chemicals such as carbon tetrachloride and trichloroethane.
  The solutions for the ozone hole, there is no specific solutions for this issue, the most effective method is mitigate the emission of the CFCs substances which may destroy the ozone layer, and wait for the natural repair.
  I appeal that our human beings should care more about our earth and try our best to do less harmful activities to protect our habitat.
