We have a gas fireplace. It has a chiminey. Do you need to have ventilation to the outside
Answer
If you do not have a ventless gas fireplace it must be vented outdoors. Some states have banned these fireplaces due to environmental and safety hazard reasons. They potentially build up carbon monoxide, deplete oxygen, and lead to unconsciousness or even suffocation. Even with a outdoor vented fireplace, when you are burning indoors any type of liquid or solid fuel for heating, cooking or other use, you should have an active carbon monoxide detector installed in your home.
If you have fuel-burning appliances on more than one level of your home, you should have a carbon monoxide detector on each floor. For example, if you have a gas range on the main floor and a furnace on the lower level, you should have detectors on each of these floors.
Such fuel-burning appliances are generally tested and safe to use, but should there be a clogged vent line or any part of the appliance that becomes faulty, it could release hazardous levels of carbon monoxide in your home and death can occur within minutes. But you can keep your family safe by using a carbon monoxide detector which can alert you to the presence of this silent toxic gas.
If you work regularly on running vehicles in a closed garage, you should also consider installing a unit in that area.

What impact do humans have on the carbon cycle? ?
Q. What impact do humans have on the carbon cycle? ? i need help on that
my teacher told me "You are confusing carbon dioxide and carbon monoxide"
here is my answer[you don't have to read if you don't want]
"Humans take fossil fuels, burn them to release energy, and produce CO2 in the atmosphere. Humans and other animals breathing CO2 is normal part of the cycle. Taking billions of years of collected solid carbon deposits, and burning them into the atmosphere as CO2 within a couple-hundred years, is NOT the normal part of the cycle. The CO2 breathing plants are not keeping up, and the CO2 is accumulating. It's bad that Carbon Dioxide is accumulating because it has a greater affinity for hemoglobin than oxygen and can kick the oxygen off of hemoglobin causing a person to suffocate, but you can't smell it or taste it so it is extremely dangerous. That's why they have home CO detectors.
"
so what's the correct one?

Answer
Good answer but the chemical that you described at the end is Carbon Monoxide not Carbon Dioxide (two very different chemicals in the way they behave and abundance). CO2 is far more abundant than CO not as nearly as dangerous (or at least not as inherently dangerous). CO2 does NOT have a greater affinity for hemoglobin than oxygen, however CO does and that is why it is so much more dangerous.
