Factory filter Help save the world! the world's fate is in your hands. air pollution is the number one leading cost of the ozone layer disappearing. My father's tow trucks are diesel so they are not very friendly to the world but he just got a new truck that has 3 filters that filter out about 65% of the bad stuff that comes out of these tow trucks. If this technology could be used on a much bigger scale it could help the world's ozone layer last longer. That is why I am doing this because in my research I have found that car emissions and factory emissions are the two leading costs to the ozone layer giving out. Car companies have already help with cars emissions but what about BIG factories I don't really see them doing very much about
