If humans continue doing nothing to reduce their impact on the carbon cycle then the levels of carbon dioxide in the atmosphere will continue to rise.

Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change.

Just like humans do they breathe it out. They then remove carbon when they eat. This is part of the natural carbon cycle, and does not add extra CO2 to the atmosphere.
Carbon affects the atmosphere when humans burn fossil fuels into the air and other chemicals

they obtain carbon by humans and organisms, etc.
The carbon cycle moves carbon in and out of the atmosphere, the land, plants and animals, and the oceans. Carbon dioxide in the atmosphere is a greenhouse gas that keeps the planet warm. Too much carbon dioxide in the atmosphere, from humans adding it by burning fossil fuels, is causing an accelerated greenhouse effect, global warming.
Just like humans do they breathe it out. They then remove carbon when they eat. This is part of the natural carbon cycle, and does not add extra CO2 to the atmosphere.
Extra carbon is getting into the atmosphere because of the actions of humans. These actions would include deforestation, pollution, and the burning of fossil fuels.
Large amounts of carbon dioxide (CO2) entering the atmosphere appears to contribute to global warming. One way humans contribute to this problem is by burning fossil fuels.
