The usual answer to this question is "transportation" however, this is correct only if you mean "anthropogenic" or manmade sources. If you include natural sources "Nature" beats man hands down. Of those sources "Decomposition" is the leader.
Natural sources such as particulates from windblown dust, carbon dioxide from decomposition, methane from outgassing of the tundra and ruminant flatulence, heavy metals in water in the North of Canada, chloride and bromide contributed to the atmosphere from sea water spray, radon from granite, nitric oxides from lightening, volatile organics from pine forests, sulfur dioxide from volcanoes, ozone from stratospheric ozone by mountains are much greater than the manmade sources.
As an example man made carbon dioxide accounts for about 6 billion tonnes a year while natural sources produce several hundred billion tonnes a year
When the atmosphere is contaminated by pollutants from human and natural sources, it is referred to as air pollution. This pollution can have harmful effects on human health, the environment, and the climate. Major sources of air pollution include vehicle emissions, industrial activities, and natural events like wildfires.
Dirty air is often referred to as pollution, particularly air pollution. This can result from various sources such as vehicle emissions, industrial activities, and natural factors like wildfires. Pollution can have detrimental effects on human health and the environment.
To write a paper on the causes and effects of air pollution, first, research different sources to understand the various factors contributing to air pollution and its impacts. Organize your paper by outlining the key causes and categorizing them as human activities, natural sources, or industrial processes, then detail the effects of air pollution on human health, environment, and climate. Conclude by offering potential solutions to mitigate air pollution and its harmful effects.
nonrenewable
Three natural sources of air pollution include volcanic eruptions, wildfires, and dust storms. These events release large amounts of pollutants such as sulfur dioxide, carbon monoxide, and particulate matter into the atmosphere, contributing to air pollution.
cars and buses, mostly
what are the main sources of maine pollution
The two main sources of air pollution are the toxins released from factories and automobiles.
When the atmosphere is contaminated by pollutants from human and natural sources, it is referred to as air pollution. This pollution can have harmful effects on human health, the environment, and the climate. Major sources of air pollution include vehicle emissions, industrial activities, and natural events like wildfires.
The kind of pollution comes from track able sources is usually trash pollution in the water. Air pollution and fossil fuel pollution are also track able sources.
The two major sources of air pollutions are motor vehicles and industry.
I DONT UNDERSTAND ALL THIS AIR POLLUTION.
This is called Ozone because Ozone is harmfull and so is air pollution
transport or industries
The oil sands are a major resource which also contribute to air pollution.
Most human activities cause air or water pollution.
Air pollution is one of many major forms of pollution. It causes major damage to the environment including acid rain.
