Earth’s Atmosphere By Ikotun Oluwatoke Environmental science 2000 Student number: 7733112 Introduction Human activities has caused increase of dangerous air pollutant and climate change which has led to serious health illness, the increase in population is directly proportional to the increase in human sources of pollution. In the early model of Earth’s atmosphere, oxygen was a minor component of the Earth’s atmosphere and so many theories were made up for why this was so. However, as…

that greenhouse gases emitted by the human population cause global warming. Greenhouse gases come from a variety of sources such as the exhaust of automobiles, and even from cattle in feedlots. The gas most responsible for global warming is carbon dioxide a waste gas emitted by most living things, which…

This is good news but the bad news still remains in play. Vehicles were a huge impact on the environment by releasing carbon dioxide into the atmosphere and destroying the ozone layer. Spending billions of dollars on the conservation movement has been a helping hand the situation but the track it is on will take numerous decades to finally eradicate and in doing so, the research…

Global warming or climate change is the gradual increase of Earth’s temperature over time, through the greenhouse effect. The greenhouse effect is the rising carbon level in the atmosphere, trapping radiation, and heating the Earth. Humans are depending on fossil fuels that release these emissions. Though we have increasingly started depending on renewable resources that don’t release these harmful gases into the atmosphere, we can already see the effects today and if this doesn’t stop now the…

All organisms in an ecosystem are interconnected and play specific roles that are crucial to the entire community’s sustainability and well-being. When a single aspect of the community is taken away, it affects the rest of the organisms that inhabit the ecosystem, and usually in a way that negatively impacts the area’s biodiversity. The source of most energy on Earth comes from the Sun however, only a certain group of organisms can harness the sun’s energy and convert it into sugars and…

the earth will still continue to warm at a rapid pace due to the carbon dioxide still present in the atmosphere, mind you CO2 has a residence time in the atmosphere of over 100 years. The most viable solutions to this problem have been geo-engineering methods, some of which are extremely clever, but also extremely costly and impractical. A lot of the proposed solutions have to do with removing the already present carbon dioxide gas through methods that involve installing stations equipped with…

It is on the local news or found in the newspaper. It is in the air that people breathe every single day. However, many humans are still not aware of the harmful effects of global warming. Carbon is emitted into the air daily because of the burning of fossil fuels. Eventually, we will run out of fossil fuels. Then what happens? There are plenty of clean alternatives that put little to no greenhouse gas into the atmosphere. One small switch at a time could save a population of polar bears or even…

destruction of the environment. The natural gas option that was previously seen as more climate friendly, is actually seriously harming it. Fracking has been proven to be linked to leaks of methane 23 times more potent in greenhouse gas than carbon dioxide. A recent study by the National Oceanic and Atmospheric Administration on Opposing Viewpoints, monitoring gas wells in Weld County, Colorado, estimated that 4 percent of the methane produced by these wells is escaping into the atmosphere. The…

reaction that requires water, carbon dioxide and energy from the sun to produce glucose and oxygen. In the process of photosynthesis water is oxidised and carbon dioxide is reduced. The process of photosynthesis consists of two parts; a light-dependent reaction and a light-independent reaction. In the light dependent reaction the energy from light moves the electrons from a photosystem into to high energy state. In the light dependent reaction carbon dioxide and a few other compounds are…

The Climate & Weather Webpage states, “It is estimated that more than 1.5 billion tons of carbon dioxide are releases to the atmosphere due to deforestation, mainly the cutting and burning of forests, every year,” (Characteristics of World Weather and Climate ). Not only are we removing the only thing that absorbs CO2, but we are also piling even…
