Directions: Read the following passage．Fill in the numbered blanks by using the information from the passage．
Write NO MORE THAN THREE WORDS for each answer．
Air pollution refers to the introduction of some harmful gases and particulate matter （颗粒物质） in the Earth's atmosphere which in turn results in pollution of air that the various forms of life require for various life processes．There exist natural causes of air pollution such as volcanic eruptions, wildfires, etc．as well as human causes such as vehicle emissions, industrial smoke, etc．Over the last few decades, the air pollution caused by humans has become a lot more serious and common than natural air pollution．
Air pollution affects all forms of life including humans, plants and animals on the planet．Along with humans, animals are dependent on oxygen in the air．When polluted air is inhaled （吸入） for breathing oxygen, several harmful gases are also inhaled along with this life-saving gas．These harmful gases are believed to affect animals in the same manner in which they affect humans．Experts also suggest that the particulate matter the animals inhale over a long period can gather in their tissues and cause damage to their organs in the long run．In addition to inhaling the harmful contaminants （污染物） directly, animals can also come in contact with these contaminants from the food they eat and absorb them through their skin．Some studies do show that the effects of air pollution on animal species are much more serious than they are on us humans．
The rapid rate at which air pollution is occurring is not even giving the animals a chance to adapt to the changes in the environment．In the long term, these effects are likely to result in extinction （灭绝） of species, which will indirectly add to our danger because we along with all these animals form the ecological environment where all species depend on each other．Therefore, all of us are supposed to make an effort to reduce air pollution．
