The acidity of rainwater in Japan, for example, showed the determination of PH and other components in rainwater collected from 2 different sites (areas industrial and residential) showing the air pollution effect of pollution on rainwater (Adashi, Asaka, Ozama, Sawai, & Kobayashi, 1990). This research can also explain the continuing effect of acid rain that can change the ecosystem, which happens to be the primary resource of our planet because the existence of all humans, animals and plants depends on the ecosystem. Furthermore, climate change which is another modern effect of air pollution, there are many countries that have to worry about this notable change as people are affected in many circumstances such as typhoons, heat waves and droughts which can cause damage to life and the environment.
