by less poluting
As more people pack into Japanese cities noise pollution increases proportionally. Noise pollution and air pollution are connected to an increased number of vehicles on the road.
Vehicles release carbon monoxide into the air from the combustion of fuel in their engines. And the amount of such kind of pollution is very great, mainly in big cities.
one of the main causes of air pollution in cities is emissions from vehicles like cars and trucks. an old or poorly tuned engine will produce more pollutants in the air ,rather than a new and well tuned engine. so,it is checked for vehicle emission and air pollution safety.
The large population of cities
Pollution
Water pollution kills birds, fish and other animals. What can factories do to cut down on air pollution?
The use of CNG (compressed natural gas) as a fuel in vehicles can help reduce air pollution in cities. CNG burns cleaner than gasoline or diesel, emitting lower levels of pollutants such as carbon monoxide, nitrogen oxides, and particulate matter. This can lead to improved air quality and reduced health risks associated with pollution exposure.
of course the water pollution is more............Because big cities have lots of Industries.........these wastes were mixed in air or otherwise to water...........These leads to water pollution.............
Car pollution is a significant issue globally, contributing to air pollution and climate change. The impact varies based on factors like the number of cars in use, emission standards, and fuel types. Countries are taking steps like promoting electric vehicles and improving public transportation to reduce car pollution.
The cities that have the worst air pollution is Pittsburgh and Los Angeles
Effective ways to reduce air pollution in cities include promoting public transportation, implementing stricter emissions standards for vehicles, increasing green spaces and trees, and encouraging the use of renewable energy sources.
