What impact do humans have on the carbon cycle?

Human activity impacts the carbon cycle by introducing more carbon dioxide into the atmosphere: carbon dioxide accumulates in the atmosphere, changes temperatures and alters the salinity levels of oceans, disturbing the salt and water balance equilibrium that supports proper growth of marine plants and animals. read more

Humans affect the carbon cycle by exhaling carbon dioxide, burning fossil fuels, cutting down forests and poor farming practices. While breathing is necessary to survival, there are other ways to slow the cycle. read more

Humans distort the carbon cycle. Since the industrial revolution, humans have released large amounts of greenhouse gasses into the atmosphere through burning fossil fuels and biomass such as trees. This results in the movement of carbon from these carbon reserves (wood, oil, gas, etc.) into the atmosphere. read more

The carbon cycle involves the movement of carbon between the atmosphere, biosphere, oceans and geosphere. Since the Industrial Revolution approximately 150 years ago, human activities such as the burning of fossil fuels and deforestation have begun to have an effect on the carbon cycle and the rise of carbon dioxide in the atmosphere. read more
