![]() Humans have inadvertently reduced or eliminated the ability of the terrestrial biosphere to absorb CO2 through land clearing and soil matter reduction. Human impact on the carbon cycle is substantial. Larger amounts of carbon are now transferred to the atmosphere due to disruption of precipitation and CO2 release from human manufacturing, vehicle use, and agriculture. This balance is changing, however, due to human activity. Normally, the oceans store the most carbon. Oil and other fossil fuels are examples of sediment material that humans use for energy purposes. Carbon in these layers can be released either very slowly or very quickly, either by a volcanic eruption or human activities. The Earth’s SedimentsĬarbon becomes trapped in the Earth’s sediment layers by way of slow geologic processes. In recent years the oceans temperature has increased and become more acidic because of balance of the increase of CO2 in our atmosphere. In the ocean carbon cycle, carbon, oxygen, and hydrogen are constantly exchanged between the oceans and the atmosphere. The OceansĬarbon enters the oceans through the water cycle and the formation of carbonic acid from rocks. In addition, disrupted soil that contains lower levels of soil organic matter holds less carbon than rich, healthy soil. Crop and farmlands, which now make up over 35 percent of global landmass, hold less carbon than forests. The amount of carbon that these systems can hold is reduced as people conduct large-scale manufacturing and agriculture. The terrestrial biosphere includes plants, animals, forests, and soil systems across the planet. Now, this delicate balance is shifting due to human activity. These are: The AtmosphereĬarbon is released from the oceans and through man-made processes and is then suspended in the atmosphere before being absorbed back into the ocean and soil. The major carbon reservoirs on Earth are places where large amounts of carbon is stored and then moved through the fast and slow carbon cycles. The fast carbon cycle is tightly tied to plant life on Earth, so much so that scientists track seasons and carbon levels by measuring plant growing seasons. This is expelled as waste products into the soil and oceans, beginning the cycle again. Plants consume carbon and create sugar (CH2O+O2), which is then consumed by plants, animals, and microscopic life. Phytoplankton (microscopic organisms in the ocean) and plants absorb carbon via photosynthesis. This cycle relies on the world’s oceans and life forms. According to NASA, between 1000 to 100000 million metric tons of carbon moves through the fast carbon cycle each year. The fast carbon cycle, on the other hand, describes a faster process for moving carbon atoms around the world. ![]() This carbon remains on the ocean floor until volcanic action returns it to the atmosphere. Once in the ocean, these ions bond with other ions to produce calcium carbonate, a compound that is essential for undersea organisms to form shells. These rocks form ions, such as calcium, and these ions runoff into rivers, and eventually, into the sea. Carbonic acid in rainwater then falls on rocks, slowly dissolving them. The slow carbon cycle occurs when atmospheric carbon combines with water to form carbonic acid. The cycle is broken up into two components: the slow carbon cycle and the fast carbon cycle. Asking “what is the carbon cycle” is a vitally important question for business leaders, policymakers, and anyone impacted by the rapid changes taking place in our environment. The carbon cycle is being disrupted by humans on a scale never seen before due to anthropogenic climate change. What is the Carbon Cycle?Īccording to the website for the National Ocean Service, the carbon cycle is the “chemical backbone of life on Earth.” The carbon cycle describes the processes through which carbon travels on the earth. In this article, we will work to describe to you what the carbon cycle is, what the major carbon reservoirs are, how humans affect the cycle, and what actions humans can take to reduce their impact on the carbon cycle. ![]() If you want to take an informed position on nearly any issue that concerns the environment, you should understand how the carbon cycle works. Today’s concerns for food production, human migration, and water management are all intimately connected with the carbon cycle and how human activity affects it. ![]()
