According to real estate website Realestate, data from the World Health Organization's (WHO) Global Environmental Air quality Database, (World Global Ambient Air Quality Database), show that the air in all cities around the world is polluted to a certain extent. As many as 9 to 10 percent of the population breathe highly polluted air.
But Australians are lucky because Australia is one of the cleanest countries in the world.
It is reported that the air quality index between 0 and 50 is "excellent." Australians breathe the healthiest air in the world.
Of these, Melbourne had an air quality index of 30, Perth [measured at Cafsham (Caversham)] was 37 Adelaide, and Melbourne [measured at Winniria (Winnellie)] was 18. 8%.
Horbart has the lowest air quality index, with 3.Sydney (Landwick (Randwick) measuring 46, the highest in the state.
The region with the highest air quality index in Australia is Sydney's St. Marius (St. Mary's), of 62. 5%.
Although Australia's air quality is good at present, there is uncertainty about the future because of the lack of consensus on climate change policies and the lack of proactive action.
On the other hand, there are some cities around the world air pollution is very serious, threatening human health.
Air quality index more than 300 is considered dangerous, while India's Delhi (Delhi), and Turkey's Ankara (Ankara) air quality index is as high as 999. In addition, the Monterey (Montril) index of Spain is 495 and Chengdu of China is 382.
Residents living in these areas are more likely to experience respiratory problems, cardio-pulmonary disease, and even premature death.
