It is not half. It just like total of pollution is happen by air.
our cars, factories, fireworks,rubbish in rivers, chemical in rivers come on people litter 68 percent!!!they dont bother to put it in the bin
volcanic eruptions, industrial processes the produce excessive noise or heat, and from human activities that release chemicals.
Human activity can effect the enviroment. How bad it does depends on what the people do. To pencils you cut down trees. Which effects the enviroment. Just things like that.
Industrial activities that cause water pollution include releasing chemicals into rivers
gas from the exaust of an engine, power plants and other factories and from sewer water.
People and scientists have come up with some ways to prevent pollution. Some of these is using filters on cars and factories along with making it illegal to litter.
Pollution is really bad and needs to stop. So put down those car keys and walk to the store next time.
No. The sources of pollution can be caused by humans or natural. Examples of man-made pollution include cars, trucks (diesel ESPECIALLY), woodstoves, fireplaces, etc. The pollutants that come from activities such as driving a car or running a factory are particulates, ozone, carbon monoxide, nitrogen dioxide, and toxic air contaminants. Examples of natural-caused pollution come from volcanic eruptions, forest fires, and dust storms.
Vehicle exhaust fumes. Fuel emissions. Coal burning factories. Mass burning of forests and vegetation.
Pollution is going to end when all people in the world stop smoking and using cars and all of the gassy things. Pollution's definition is an undesirable state of the natural environment being contaminated with horrible substances as a consequence of human activities. Pollution is very bad for our environment. In china pollution began. So to answer the question about how long will pollution be in the air... it will problably forever unless we all come together as one to STOP POLLUTION ONCE AND FOR ALL!
The human mind creates them, then factories build them... like everything else.
liver disease there is also alot of pollution in the air because of the factories and the cars,and they eat alot of carbs. (bread, past, pastry)
