Fake Trees And Fans Could End Air Pollution

People today don't even realize how much we pollute the world we live in. Scientists try and warn us about pollution, but nothing is really changing. Almost every form of transportation spits out carbon dioxide, and our breathing process does as well. Carbon dioxide is all around us, and although plants are helpful in breathing in the "bad" (CO2) and releasing the "good" (oxygen), the rate we produce air pollution is too fast for the plants to absorb. The carbon dioxide left in the air makes it more hot, which is the reason for increased global warming. Scientists are trying to find another way to take carbon dioxide out of the air, and put it somewhere else. So, labs around the world are building their own carbon sinks (process of producing more oxygen and taking away CO2). They are doing so by finding materials that will essentially suck the carbon dioxide out of the air. Labs at Arizona State University are making artificial trees using a sticky CO2 absorbing substance. A Canadian company is making a wall of fans that have an absorbent liquid in them that will suck in CO2 and turn it into a salt. Although both of these technologies are great ideas, neither of them are ready to be put to use yet due to size, efficiency, and cost.
