Too much air pollution will endanger our lives. Air pollution such as nitrogen oxides, sulphur oxides, carbon monoxide, ammonia, and many other harmful gases affect our health, may kill or cause negative impacts on living things and will corrode away buildings and other materials in times. Some of these gases deplete the ozone layer which arises the global warming. As temperature increases, glaciers and ices are melting which may lead to natural disasters, loss of habitats for certain species and extinction of species. A source from (http://en.wikipedia.org/wiki/Air_pollution) states that 2.4 million people die each year due to air pollution. In brief, air pollution has caused great disadvantages and we have to wisely prevent too much of air pollution.
