What percent of pollution are humans responsible for?

Answer 1

There are two equally correct answers to this question, all and none. Some people consider anything man does as as a source of pollution and disruption of the natural state of things. Thus, man causes all pollution, because every thing else is "natural". Others consider man part of the natural state and therefore any done by man is natural and not pollution. Thus man cannot cause pollution because we are part of the "natural system" on Earth. It also depends on what is considered a "pollutant". Let's talk about air pollution. Common auto pollutants are HC, NOX, CO, and particulates. Some people also add CO2 because it is a green house gas. Water vapor is the most common and important green house gas. The human body produces HC as part of digestion, respiration (breathing) generates CO2 and water vapor and our skin releases "particles" into the air as new shin continuously replaces old. Of course humans do not just contribute to air pollution. They contribute to water pollution, noise pollution, and light pollution also.

Answer 2

There must be a lot because the hole in the ozone layer is steadily growing bigger. Only pollution and carbon monoxide could cause this. The Earth must be very polluted. If we don't stop now, the ozone layer will disappear, and the Sun's rays will fry us to death!!!!! Sorry, that was a little morbid...

Answer 3

100%

Answer:

Pollution is usually regarded as a human caused problem, however there are many examples of natural pollutant source:

• Volcanoes give off particulate, sulphides and sulfur dioxide, and carbon dioxide.
• Animals pollute waterways with teir waste
• Arsenious rocks add toxics to the water in the area
• natural oil seeps cause oil pollution problems similar to a spill
• Forest fires release carbon dioxide and cause soils to leach toxic materials
• Stratospheric ozone is washed out of the stratosphere causing ground level ozone
• pine trees give off turpenes and other organics to the air
• Decomposition releases methane and carbon dioxide

These emissions are usually not reported as pollution but are similar to human made emissions.

Answer 4

The amount of pollution in the air alone has increased by 5 fold in the last 100 years. There is however no way to tell exactly how much pollution is in the world collectively.

Answer 5

True or false? Factories produce less air pollution than motor vehicles?
