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.
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...
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.
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.
Us... We are recking are earth! We need to stop
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
