答案 The pie chart above depicts the proportion of several sources of atmospheric particulate matter, PM 2.5 in particular. Apparently, it manifests that human activities, such as coal combustion, the burning of fossil fuels in vehicles, power plants and various industrial processes generate significant amounts of particulates. The aim of the drawing is to reveal the causes of air pollution which is getting increasingly serious in our modern society. In fact, PM2.5 crisis should be our uppermost concern. Otherwise, human health will not be guaranteed and our environment is bound to deteriorate. To begin with, inhalation of particulate pollution can have adverse health impacts. Even for healthy people, polluted air can cause respiratory irritation or breathing difficulties during exercise or outdoor activities. What’s more, with increased temperatures worldwide, increase in sea levels and melting of ice from colder regions and icebergs, displacement and loss of habitat have already signaled an impending disaster and actions for preservation and normalization should be undertaken soon. Therefore, counter-measures to deal with PM2. 5 crisis should be taken so as to return human a safe, healthy environment to live in. Emission standards must be also established, the limits for particulars must be set and laws must be legislated to punish the air polluters.
