There are many human activities that affect the oxygen cycle, having a big impact on the photosynthesis process. Due to humans burning oil and other fuels, carbon dioxide gets released into the atmosphere, as well as having trees and plants removed, making fewer products to absorb carbon dioxide. Population is another big human activity that affects the oxygen cycle, by having more people there are not enough plants and trees to absorb carbon dioxide, making humans plant more trees and plants in order to get oxygen into the atmosphere. It is a big issue in the ecosystem for the oxygen cycle, making it harder to do the photosynthesis process.
The evidence that humans are affecting the oxygen cycle is that in 2012 there was an estimated 21.3
Human activity plays a moderate effect on global warming. Although we are major source of releasing carbon dioxide through cellular respiration, I do not believe it causes an imbalance in our atmosphere. The way humans do affect that imbalance is when deforestation takes place, and start building industrial plants, cars, etc. Think about the amount of industrial building all over the world that needs fuel to run and not to mention all the machinery that is used every day to construct and run
...oceans. Anthropogenic systems such as the combustion of fossil fuels since the industrial revolution have greatly increased the rate of acidification to levels where negative impacts ensue. Negative impacts occur both to marine organisms that rely on certain water conditions to maintain vital functions and the environment which is damaged by highly acidic waters. There is great variation in the acidity of each of the oceans, differences caused by the chemical composition of the ocean and biogeography. Understanding of the potential impacts of ocean acidification is relatively new to the scientific community and therefore little is known on how to counteract anthropogenic influences. Although reducing the amount of carbon dioxide produced will in turn reduce the lowering of the oceans acidity levels and reduce negative impacts on the environment and marine organisms.
Human activities have led to an exponential increase in the use of fossil fuel. The benefits of using fossil fuels are short lived in comparison to its long-term negative effects. In the last couple of decades, the major consumption of fossil fuel played a significant role in the rise of concentration of CO2 in the atmosphere. Roughly two trillion metric tons of CO2 have been emitted in the atmosphere and over a quarter of these got mixed with the ocean water resulting in ocean acidification (Buffie and Carr, 2010).
Stratospheric ozone absorbs 97-99% of ultraviolet radiation. As this protective layer continues to dissentigrate, human health will suffer. One American dies every hour from skin cancer, a direct result of ozone depletion by anthropogenic chemicals, primarily CFCs, which damage the ozone layer. Alternate chemicals are now being used in the place of CFCs that will not damage statospheric ozone, and there is international recognition of the importance of developing these chemicals. The Montreal Protocol is an international treaty which limits the production of ozone depleting substances. Still, human health is at risk from the deletion of ozone, and the risk factor will continue to rise unless people and industries become more aware of the implications connected with everyday use of chemicals which destroy stratospheric ozone.
When people burn fossil fuels to accumulate and produce energy a substance called carbon is produced. Carbon is released into the air in a form known as carbon dioxide. Carbon moves throughout the biosphere on the planet as it is recycled and reused. Carbon exists in the earth’s atmosphere in two common forms which are methane and carbon monoxide. These gases absorb and retain heat in a process known as the greenhouse effect. The Planets natural greenhouse effect makes life possible by regulating our temperature. It turns out that adding too much to the greenhouse effect can have horrible consequences on the environment. Each year, five and a half billion tons of carbon is released by burning fossil fuels and of that three billion tons enters the atmosphere. The remaining carbon usually gets absorbed by the oceans.
There are lots of natural processes constantly happening all around us, these processes are often linked by passing one type of atom to the next process which passes the same atom to the next one and so on. This ‘passing of the atom’ along a chain of processes is called a cycle, the series of processes in which the carbon atom goes through is called the carbon cycle. Each Carbon is the fourth most affluent element in the universe and is an important part of most molecules that make up most of the world’s natural resources and organic matter, which is why the carbon cycle is one of the most important cycles on earth. Through-out the cycle, carbon can become several different forms such as sugar, oil, diamond and marble. Processes such as photosynthesis, combustion and the compression of the earth play key roles in changing, containing and releasing carbon. All the chemical reactions and processes and forms carbon creates are part of the carbon cycle, which is one of the most important cycle on earth. The majority of carbon on earth is in the atmosphere the rest is stored in rocks, fossil fuels, oceans, plants and soil. Carbon is constantly being added to the atmosphere, the most common forms being carbon dioxide and methane gas. At the same time it’s being removed by plants on land and in the oceans. Carbon can be stored for hundreds of years in sediment, fossil fuels, rocks and the ocean. The carbon in the atmosphere is almost always a compound called carbon dioxide.
The argument to support the fact that global weather patterns have changed, draws its evidence from a number of sources and documented events, and by observation of what is happening in the environment. The increase in carbon emissions from industry, transportation and farming practices is widely accepted as being responsible for the greenhouse
Well known, this issue can be the main cause for many problems in our environment
Carbon is one of the elements present in the periodic table, represented by a C, it is one of the elements that can combine with other elements to make molecules and it is also the fourth most abundant. On earth, carbon circulates through the land, ocean, and atmosphere, making what's referred to as the "Carbon Cycle. ", and in a non-living environment or things, like rocks, coal, petroleum, dead organic matter and etc., carbon exist, but as carbon dioxide (CO2).
Gas has many effects in our society, and some of these effects have a negative impact in our life. Our daily lives depend on gas, when we go to work, school and going out. We use gas for electricity, cars and many other things. The effects of gas are direct and very affecting in our lives because of the many forms it can be used in. There are many negative effects of rising gas cutting back in vacation time, prices of everything is going up “inflation”, car companies making more efficient cars.

Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putting more than 5.5 billion tons of CO2 into the atmosphere every year. 75% of this is caused from the burning of fossil fuels. These fuels are burnt all the time to run factories, power plants and vehicles. The main sources of CO2 emissions are electric utilities, residential buildings, industry and transportation. The other 25% is induced by the destruction of the world's forests. The reason for this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.
They also purify the air we breathe and water that we need to survive. Deforestation by humans is causing these functions to be lessened and damaging the atmosphere even further. (www.climateandweather.net) Deforestation is one of the major factors contributing to the greenhouse effect and desertification
It was not until 1950, that the carbon dioxide level exceeded the average and almost doubled according to NASA. In the article written by NASA, it was stated that there is different amounts of carbon dioxide and other gases in the atmosphere that started to appear in the mid-nineteen century. These gases are produced by the greenhouse effect and other different mankind activities like the burning of fossil fuels, clearing of land for agriculture, and industry. Humans contributed in the change of the natural effects of the greenhouse. The burning of fossil fuels like coil, oil, and other fuels is the number one way that mankind has changed the greenhouse effect. The number one chemical that fossil fuels contain is carbon. When carbon is released to the atmosphere, it mixes with oxygen to create a harmful chemical, known as carbon dioxide. Carbon dioxide is the most harmful chemical to the atmosphere because this chemical traps heat in the atmosphere which cause temperatures to increase(Climate Change
