Industry is looking for solutions to the air pollution problem. The best solution would be to stop burning fossil fuels all together but at this time we have no other alternatives. Scientists are trying ways to cut down on pollution. One way is to wash the coal before they burn it. Washing it takes off most of the sulphur but not all of it. The rest would have to be removed chemically but this process is still being researched. The problem with this is what to do with all the excess sulphur. Another solution is to clean the smoke before it is released into the air. Many filters have been installed in smoke stacks but again this solution is not 100% effective.
Causes and effects of pollution:
Another major environmental problem caused by air pollution is global warming or the "greenhouse effect". The greenhouse effect is caused by solar energy being trapped by CO2, Methane, Ozone (O3), Nitrous gas, and Chlorofluorocarbons (CFCs) that are in the air. The solar energy comes into the atmosphere as light, it hits the Earth, looses some of its energy and becomes heat. Because the heat does not have as much energy it can not penetrate back through the blanket of gases. The Earth has a natural greenhouse effect caused by the CO2 in the atmosphere. If we didn't have this natural greenhouse effect, the Earth would be too cold to live on. We have increased this effect through the release of all the gases I have mentioned above.
