To the trick people

Contrary to what people think the filters in factories to reduce pollution, has some truth and part lie.
By burning fossil fuels is not only released the Carbon dioxide but also a substance called aerosols.
By introducing the filters in factories, filters just will filter the aerosol and not the Carbon dioxide, in it has the good and the bad part. The good part what causes the air unbreathable is the aerosols, such as the United States if the factories not have these filters the population would have to walk the streets with masks. But it also has its bad part, so to filter the aerosol is released Carbon Dioxide. The greenhouse effect that people hear talking is when the sun's rays enter the atmosphere, are reflected in the oceans and the poles and is projected to space as the planet was to get a high percentage of Carbon dioxide does not leave the sun's rays are projected into space, just causes a greenhouse effect. The Carbon dioxide is breathable, but has the problem of letting in the sunlight and not let them out again by the atmosphere, causing global warming accelerate. The political summit to show the audience that will force the factories to get Filters do not for pollution, is only fooling the people, not being told the whole truth.
Most people have never heard of aerosols, as I discovered it so that after reading the book "The Seventh Seal."
