Because of pollution, air quality is degrading almost everywhere, but, at several place, the air is so contaminated it makes breathing laborious. According to the journal Deutsche Welle, from Shanghai to Beijing, the smog periods kill people by the thousands every day. This serves only to make my point that by polluting the atmosphere, humans kill themselves faster than ever before. But what happens underwater? Acidification (addition of nutrients in a body of water) creates what scientists call dead zones which are areas devoid of oxygen where most organisms cannot survive.
