Question

how has technology helped decrease air pollution in recent years

Answer 1

Technology goes a long way in helping reduce air pollution. It not only makes existing technology that releases pollutants more efficiently but it also finds alternate sources of energy that are non polluting or environmentallyfriendly. 

The major cause of air pollution is the burning of fossil fuels for energy. Technology helps design engines that are more fuel efficient there by reducing the amount of fuel being consumed. Technology in the form of solar energy panels, wind turbines, breeder reactors, geo thermal power all help reduce the burning of fossil fuels. Hydrogen fuel cell powered cars and electric powered cars are an alternative to petrol and diesel driven vehicles. Power generation is mostly accomplished through the burning of coal and natural gas powered plants. Though technology is helping us fight air pollution it has got us here to this point in the first place.
