Human Impact On The Carbon, Phosphorus, And Nitrogen Cycles

The Carbon Cycle is a process necessary to all life forms as carbon is used for photosynthesis, cellular respiration, and is found in all living organisms. This process occurs naturally from cellular respiration, decomposition, and volcanic eruptions. However from burning fossil fuels and cutting down trees at a rapid pace carbon dioxide is being released into the atmosphere at an artificial rate. The overabundance of atmospheric carbon dioxide is causing for global warming. This global warming is causing extreme havoc to the Earth and all of its life forms. However this damage, although cannot be reversed, can be changed for the better.

Human impact on the cycling matter in ecosystems can change a lot of things. Humans can either help or hurt things. The carbon, nitrogen and phosphorus cycles are the three cycles of matter in ecosystems. What are these cycles? How do humans effect each one of these individual cycles? What are some examples of humans effecting these cycles?

The biosphere consists of a compound infusion of gases; the main components are oxygen, nitrogen, and carbon dioxide. The concentration of these gases have been changing for many years. For the most part, this is influenced by human activity. In a persistent effort to improve the quality and longevity of life, humans (particularly in industrialized societies) have tendencies to negatively impact the environment, and at the same time, we strive to replenish what we have nearly depleted to balance the scale.

When trees are burned, CO2 is relinquished. The burning of astronomically immense areas of trees is known as deforestation. Human activities integrate more CO2 into the atmosphere through activities like the burning of fossil fuels. The guiding question of this investigation is, “Which carbon cycle process affects atmospheric carbon the most?” The researchers initially wanted to learn 2 things. First, the researchers wanted to learn how much carbon engenderment there would be if they incremented the amount of fossil fuels burnt by a certain amount. The researchers also wanted to learn how much carbon engenderment there would be if they incremented the amount of deforestation.

The human race all around the world wonders if the climate is changing due to human activity or if it is just a natural occurrence. At certain parts of the Earth's surface, the climate can be observed much differently than other locations. As the years go by the average temperature of the Earth increases by little intervals. There are several different reasons why people believe the climate is changing every year. However, the increase of worldwide population and production of heat to the atmosphere is due to the increase of human activities that take place on a daily basis. Human activity is the main cause of the global climate change. The human impact on climate exceeds any known changes due to natural processes. The impact of this human activity is often misunderstood when looking at climate change.

The result is that humans are adding ever-increasing amounts of extra carbon dioxide into the atmosphere. Because of this, atmospheric carbon dioxide concentrations are higher today than they have been over the last half-million years or longer.

What is the relationship between increased carbon in the ocean and increased carbon in the soil? Soil started off with a higher level of carbon increasing, but the ocean’s level of

Human activity has begun to create its own geochemical signatures and thus its own global markers through various activities. The production of phosphorus through mining has doubled the weathering rate of phosphorus released during the Holocene period. This has led to the argument that human processes have had the largest impact on the nitrogen cycle in the past 2.5billion years. However, these dramatic changes have stratigraphic consequences. The Greenland Ice Sheat Project 2 ice core has shown that the greatest decline in Nitrogen values occur between the 1950s and 1980s. This decrease in Nitrogen levels shows a distinct difference from the Holocene levels indicating the beginning of a new epoch, the Anthropocene

Recent scientific evidence indicates that humans have upset the carbon cycle, leaving more carbon dioxide and other greenhouse gases in the atmosphere. Burning fossil fuels such as oil and natural gas, burning biomass such as ethanol and wood, creating cement and releasing other chemicals into the atmosphere is upsetting the natural flow of carbon.

We, as a species, are altering levels or carbon dioxide dramatically. According to NASA, concentration levels of carbon dioxide haven’t been as high as they are now for over 1,000,000 years and that the rate of change CO2 levels in the past five years is alarming.

Since the beginning of the Industrial Revolution in the early 1800s, humans have been releasing ever increasing amounts of carbon dioxide into the atmosphere by burning fossil fuels.

The overwhelming majority (97%) of carbon dioxide in the earth 's atmosphere comes from nature, not from man. Volcanoes, swamps, rice paddies, fallen leaves, and even insects and bacteria produce carbon dioxide, as well as methane. According to the journalScience (Nov. 5, 1982), termites alone emit ten times more carbon dioxide than all the factories and automobiles in the world. Natural wetlands emit more greenhouse gases than all human activities combined. (If greenhouse warming is such a problem, why are we trying to save all the wetlands?) Geothermal activity in Yellowstone National Park emits ten times the carbon dioxide of a midsized coal-burning power plant, and volcanoes emit hundreds of times more. In fact, our atmosphere 's composition is primarily the result of volcanic activity. There are about 100 active volcanoes today, mostly in remote locations, and we 're living in a period of relatively low volcanic activity. There have been times when volcanic activity was ten times greater than in modern times. But by far the largest source of carbon dioxide emissions is the equatorial Pacific Ocean. It produces 72% of the earth 's emissions of carbon dioxide, and the rest of the Pacific, the Atlantic, the Indian Ocean, and the other oceans also contribute. The human contribution is overshadowed by these far larger sources of carbon dioxide. Combining the factors of water vapor and nature 's production of carbon dioxide, we

Ways in which humans had affected the environment in my area was by dumping drums containing paints and burying paint thinners and many other solvents into the landfill which worsened the grounds and soils of the area. The conditions though in this environment are under control and do not show any high signs of exposures to humans or creatures, meaning they have a low risk of being affected. The only actual organisms that were harmed but only in small portions included shrubs and trees in the wetlands. The site came to be polluted because of the groundwaters underneath the site, which had been contaminated by pollutants leaching from the landfills. Some ways in which we have been attempting to correct this problem was by selecting modified

Most of the blame for climate change over the years especially after the 1850’s has been placed on humans. As long as modern humans have roamed the earth, they have been upsetting the natural balance of the earth. People have did this by clearing areas of land, killing animals, polluting water, etc. Before the “modern human”, people like the Native Americans cared for the earth. They respected the land and the people that cared for it. Unfortunately, people don’t care anymore. Until recently, people did not care for the earth. People did not realize the harm they were causing it. Now we know how detrimental things are that we continue to do and used to do.

Deforestation, the cutting and burning of a forest, also increases the amount of carbon dioxide into the atmosphere. A NASA page says that “when a forest is cut and burned to establish cropland and pastures, the carbon that was stored in the tree trunks (wood is about 50% carbon) joins with oxygen and is released into the atmosphere as CO2. CO2, is, of
