his winter fog and haze much of our attention, haze harmful, several cities have in its move, so we should strengthen environmental management efforts, not let the fog and haze rampant.Causes haze presumably a lot of people know, haze you, of course, by the fog and haze is composed of a large number of the main causes of fog suspended in the air, ground water droplets or ice crystals composed of tiny aerosol system, is near the ground floor air, water condensation product. The main causes fog reduced visibility, it will cause traffic problems, but there is little risk to people.Haze is dust in the air, sulfuric acid, nitric acid and other harmful material composition, it will make the atmosphere muddy, blurred vision and lead to reduced visibility, and the body will cause greater damage. As a result two of the incoherent fog and haze The brothers came together, causing unprecedented damage to the atmosphere, the air quality in some cities has reached a point where moderately polluted, but some cities have reached the severe pollution, very terrible.Haze considerable harm, it would be road, rail, aviation, power supply systems, crop growth impact is also easily lead to the spread of infectious diseases and a variety of diseases.

It is reported that the incidence of human respiratory system in winter than last winter an increase of 30% --- 40%. This is an astonishing figure, worthy of our consideration. Therefore, prevention of fog and haze delay.Our preventive measures should be in place, in the fog and haze, we should stop doing morning exercises and outdoor sports. But this is not enough, I think the main reason for this bad weather is vehicle exhaust emissions and industrial waste gas emissions, so the state should be issued as soon as possible policies to manage and control the emission of harmful gases, more trees and grass, clean up our environment. I think that if we are mobilized, fog and haze should be crestfallen to escape it.In conclusion, I hope that we can take action, many grass flowers, more to protect the environment, create a green for our future generations, the natural environment.
