humans
Insects. Humans produce, through respiration (breathing) about 2 billion metric tons of carbon dioxide per year. If you add the production of carbon dioxide from the burning of fossil fuels and other human industry (26 billiion metric tons) and the respiration of domesticated animals (6 billion metric tons), the total carbon dioxide production that can be blamed on humans, directly or indirectly, is 34 billion metric tons. Insects, through respiration, produce 48 billion metric tons.
Volcanoes produce thousands of tons of CO2 when they erupt.
CO2 (carbon dioxide).
Because you are so up high the air becomes all different and more packed and there is more CO2.
Co2 is not needed for animal life, in fact it is poisonous. They breathe it out as a by product from using energy. However, plants must have co2, and emit oxygen as a by product.
Fission is a cleaner w/ CO2 to remove odors
Humans are ruining the Earth. First the Humans have ruined the Biosphere, by putting lot of CO2 into the air. This is also causing the summer temp. to increase each year because the ozone layer is destroyed. Now the Humans are the Ecosystem, this is not good. Once the Ecosystem is Destroyed then the Humans will destroy the communities which will affect the way we live because our food chain and food web will be messed up, not that it will be destroyed it will get messed up.
CO2 is the product of many things, but here are a few: Humans and animals exhale CO2 Decaying organic material (in land fills, for example) produces CO2 Burning organic material (forest fires, for example) produces CO2
Brewers yeast produces more alcohol and less CO2. Bakers yeast produces more CO2 and less alcohol.
It produces less CO2 than smelting iron ore
sulfur oxide
More humans.
Yes - moisture, nitrogen, alcohol vapour and any other volatile compound that happens to be in the blood or in the air that is breathed in.
No. Burning 3 candles puts out slightly more CO2 than a 13 watt CFL bulb. However, The CFL bulb puts out about 24 times more light than 3 candles. In terms of a 100 watt incandescant lightbulb, it produces roughly the amount of light produced by 120 candles, however only produces about as much CO2 as 23 candles, so you could say it's about 5 times more efficient (in terms of pollution output) than a candle. A CFL bulb, then, is about 20 times more efficient than the candle.
Well, for humans CO2 is bad for is because it gets more humid in the atmosphere, but however the plants need the CO2 to process it into oxygen. Which we need.
This Ca2+ eventually is transported to the ocean where it reacts with dissolved CO2 to form limestone. ... is a net CO2 sink because it produces abundant Ca2+ very little CO2. ... This article does not cite any references or sources. .... 1000 mg will provide 210 mg of calcium. It is more expensive than calcium.so its Mg
Yeast
cell respiration consumes oxygen and sugars and produces CO2, photosynthesis consumes CO2 and produces oxygen and sugars
Green House emissions are the creation and release of any gas that traps the sun's energy in our atmosphere. Nature produces most of these gases. Man produces one of interest. CO2 is created when man burns fuel. Humans make close to 6% of all CO2 produced and much of this (over half) from objects that would not produce CO2 if left alone. In total terms, man produces almost 0.3% of all greenhouse emissions.
