CO2 comes from all different sources. Yes humans do create some of it, but nothing compared to naturally occurring sources. Oceans emit several order of magnitudes more CO2 than humans could hope to generate. Insects, yes they breath too, also generate CO2, and they generate more than human respiration, fossil fuel burning, and industrial sources combined.

Needless to say, be prepared to turn off the lights once we start regulating something that we don't understand.

True co2 made from cars and industry only account for 1.28 % of the total production of co2 produced. Over 90% is produced from the oceans and water vapours. Volcanoes, rotting vegetation and wildlife emissions are arround 6%. Global warming is determined by the sun and rise in co2 follows the rise in temperature even by hundreds of years later . I think our contribution is not even signifigant.

No one is actually sure where most C02 comes from I think..
But most believe that its from cars and factories as the media portray this all the time...
But personally I think that its a mix of both, from natural sources to man made sources...

Everyone watches to much tv! We are being brainwashed into believing that the end of the world is near . Have you ever noticed that all major programs on tv never tell you where co2 really comes from? And that they only bank on information on global warming from all the wrong scientists. Its the reports of geologists and meteorologists and enviromental protestors ,(not scientists) are all leading to manmade co2 contributing to global warming . But its the studies of climatologists and palioclimatologists that have different reports. There is too much money to be made with convincing the world of global warming. Don't get brainwashed on this research the right science.

Greenhouse gases are gases from the atmosphere that absorb the radiation within the thermal range. The man-made causes are factory’s, cutting down trees, cars, and burning of fossil fuels.

Not 'From the atmosphere', they end up in the atmosphere (lighter than air we breathe) and come from humans burning fuels and using freon in AC's and fridges, as a now rare gas in cans of hairspray/the like.

Nature produces appx. 95% of the CO2 on our planet. Plant trees, don't stifle our economy then find out it had no effect.

CO2 is the byproduct of almost all combustions so that is cars, factories, electricity plants, etc. Even CH4 + O2 & sparks gives off CO2. Trees are/were abudant enough to convert this back to O2 but deforestation has made that impossible now.

You forget to mention that all of your sources added togeather don't even make up 4% of the total CO2. 96%+ of CO2 is from natural sources.

Carbon dioxide comes from us because we breath in oxygen and breath out carbon dioxide. Carbon Dioxide comes from burning trees and other things humans burn as well
