Question

if there were no pollution,the concentration of carbon dioxide in the atmosphere would be relatively constant.why ?

Answer 1

would it be because beside pollution, (vehicles, factories etc) the population of human beings on Earth is still increasing and we breathe out co2, so it would balance out with the natural levels of CO2.

Answer 2

humans breathe out co2,so the balance remains constant

Answer 3

yeah, lol. That's basically what I meant to say in a nutshell! haha

Answer 4

No what the hell! the CO2 we exhale is insignificanly small, besides we breath at the same time we pollute, so it makes no sense that if you eliminated pollution from the equation you still had the same result. Earth is constantly releasing CO2 and other gases naturally, (volcanoes are a good example), dead organisms when decomposed release this gases too, but great part of this CO2 is reabsorbed by plants.

Answer 5

cellular respiration ---> giving out co2
photosynthesis ----> using co2
because there both having the fixed equations in their process.. so,, if there r no dsruption or pollution, the co2 cncentration level will cnstant.. nor increase or dcrease (or maybe incrse or dcrease a little bit)..
