Air pollution

In 7 May 2016, the Sydney sky is full of fog and the air quality become very poor. The main reason is that the Blue Mountain had a range of hazard reduction fires. According to NSW Rural Fire Service, there are more than 40 placed are started hazard reduction burns in the near region of Blue Mountains ,

For the ashes of the hazard burnt will create a big smog. It will affect the viable of the city. Moreover, the greenhouse gas, for example the carbon dioxide, will be released during the tree burnt. Although hazard burn can help to reduce the risk of forest fire, the bad effect of hazard reduction burns will cause many side-effect. Therefore, I suggest the government should use the cut replace the burn of the hazard.
