Because of the Environmental Protection Agency (EPA) monitoring various industrial facilities, giving hefty fines out to those that are major polluters.
Pretty much all of them.
I DONT UNDERSTAND ALL THIS AIR POLLUTION.
Yes. All cars have begun to be built with air pollution control systems in them due to the increase in pollution in urban cities. Some cars have air pollution control systems and some don't.
Air pollution from car exhausts and smoke. Water pollution from all the litter.
No, not all cities are subject to temperature inversions. Temperature inversions occur when a layer of warm air traps cooler air near the ground, which can lead to pollution being trapped and air quality issues. These are more common in cities with geographic features that can trap air, such as valleys or areas with limited air circulation.
Air pollution, water pollution, & ground pollution.
Major air pollution disasters have all occurred in industrialized areas.
A factory chimney is high because if it was low all the pollution from it will cover the towns/cities and all the towns/cities will be covered with all the pollution so if its high its just released to the sky so it doesn't harm anyone
Bangalore is one of the most highly polluted of all cities in the world. It ranks number 14 on the planet in pollution. The air quality is so bad in some areas of the city that children suffer from asthma and sleep apnea.
Automobiles are the common source of pollution in all these cities
Most cities and countries have "Clean Air" laws that regulate how much pollution is allowed from factories and vehicles. These laws are being tightened up all the time so smog can be eliminated for ever.
Not all but most are.
