Essays on Dioxide

The human race has harmed the very planet that they live on, through their activities, since the very start of civilization. Using the resources provided by nature to fulfill the needs of the human beings is not something that is the cause of concern, but the indirect intent of incriminating damage to the environment is what the main source of concern is. Some of the impacts of human activity involve the disruption of carbon cycle, the disruption of hydro (water) cycle, and the reduction of species diversity. The major impacts of human activity on the carbon cycle include the ...

Global warming refers to the phenomenon due to which the average global temperature rises by a few degrees over a specified period of time, or as the time passes. The concern that this raises is that if the temperature keeps on rising every few years or so, it is not hard to imagine what would be its effects to the global climate and environment over the next few decades. The rise of a few degrees in a few years is not much of an issue; however, if this rise is consistent, that is where the concern of most of ...

Abstract

The ecological settings in an ecosystem change from time to time. The changes in the ecological settings are brought about by a plethora of factors. Through evolution, the organisms that live in the ecosystem also change to adapt to the aforementioned ecological changes. The adaptation of the organisms to the ecological changes yields variations because different organisms and even organisms of the same species are exposed to the elements to different levels. Man has a significant role to play in the ecological changes. Through his economic activities, the effect on ecosystems has been both positive and negative. Urbanization as ...

The laws meant that the Bowen plant of the Southern Company had to reduce the amount of sulphur dioxide released during the production of electricity. Prior to the enactment of the laws, Bowen’s sulphur dioxide emissions amounted to thirty tons an hour (Reinhardt 2). This amount translated to an annual emission of 262800 tons assuming 8760 hours in a year. Between 1995 and 2000 during the first phase of the implementation of the laws, the plant would only be allowed annual emissions of 254,580 tons of sulphur dioxide. This translates to hourly emissions of 29.06 tons (Reinhardt ...

‘Institution’ Emphysema is an irreversible condition, wherein air spaces in the lungs are enlarged, specifically those beyond the terminal bronchioles and most notably in the alveoli resulting in alveolar wall damage and airflow obstruction. This is most common among chronic smokers. (Braun, 2007) The development of an inflammation in the small airways is mainly the source of obstruction. In moderate to severe emphysema, the primary cause of obstruction is the loss of elastic recoil in the alveoli. Along with the airway obstruction, vascular changes in the lungs can be noted that will make the lining of the arteries and ...

Introduction

The issue of global warming has recently become more contentious. Ideally, a great debate exists among numerous individuals on whether it is real. According to MacMillan (Par. 1), the average global temperature over the past fifty years has risen at the most rapid rate in recorded history. In essence, the climate scientists connect the warming of the oceans and atmosphere, a strong decrease in the sea ice, and ocean level rise, among other climate-associated changes to the rise in the global temperature. The greenhouse gasses including carbon dioxide, water vapor, methane, and nitrous oxide contribute to global warming by ...

The countries and the world at large are facing many different crises currently. Different experts have come up with ways to predict the occurrence of different crisis in the near future. These predictions are important as they may give out information on how to prevent or overcome the crises, which mostly have adverse effects such as loss of lives or affect other crucial phenomena. I am going to cover predictions about climate change.

The videos are about the demonstration of a small-scale greenhouse effect. They used carbon dioxide and methane to demonstrate that when these greenhouse gases are in higher concentration, it could increase the atmospheric temperature. In these experiments, the results show that when carbon dioxide and methane are added to the normal air condition, the increase in temperature due to the lamp is higher. This is considered as a laboratory-scale evidence of the greenhouse effect which is occurring in global scale. The results demonstrated in the experiments are new to me. I already knew that greenhouse gases are the main ...

Energy has played an important role in building the world economy today. From enabling man to perform daily activities to enhancing the functioning of many industries, it is sensible to state that energy is of great importance to the world. Due to its importance, fossil fuels such as coal have thus been burnt down to create energy. However, different negative effects are associated with burning such fuels to the environment. For instance, global warming gasses are emitted thus, causing global warming as a result of carbon monoxide, which is emitted while burning coal. Despite their disparities, both developed and ...

Abstract

Several experts have been concern about the effectiveness of recycling in mitigating the effects of pollution and global warming. Some even argued that the recycling process is economically and environmentally ineffective due to the large costs and large amounts of energy required for the process. However, the practice of recycling should be continued and improved since it has numerous potential benefits against its alternatives. First, recycling is not a waste of money since the alternatives to this strategy such as incineration and landfilling has larger costs due to environmental damages. Second, issues and problems associated with recycling could be ...

What factors contributed to the problem? Volcanic activity is a major contributing factor to the issue of climate change. The eruption of volcanoes leads to the release of large quantities of water vapor, ash, dust, carbon dioxide, and sulfur dioxide into the atmosphere. In the atmosphere, these sulfur dioxide molecules will react with water vapor leading to the formation of sulfuric acid, which is then spread all over the world through winds. The sulfuric acid formed in the atmosphere can significantly affect the amount of solar radiation entering the Earth’s surface and thereby the ...

Effectiveness of Carbon Tax as Environment Policy

Climate change has emerged as a global challenge because unrestrained rising of global temperature would cause melting of glaciers and rise of sea level that would submerge land masses, change weather patterns with frequent incidence of hurricanes and floods and droughts. As an effective response to the challenge, global leaders have agreed to cut back emission of Green House Gases (GTG) to contain the global rise in temperature below 2 degree Celsius (Symon, 2013). Carbon dioxide, a major constituent of GTG, is released to the atmosphere on combustion of fossil fuels such as coal, oil, and ...

Abstract

Carbon capture is an essential approach for reducing greenhouse gas emissions. Different plants utilize various technologies in reducing carbon dioxide emission. Some of the conventional techniques employed include oxy-fuel, pre, and post-combustion carbon capture. These approaches have a high potential for capturing carbon dioxide. However, their massive initial and implementation costs have been a challenge to plants globally. Additionally, most of them are yet to experience large scale applications. Therefore, it is essential for research and development activities to be conducted. This can ensure a reduction in the cost of production. The carbon capture technologies differ in costs. This ...

Introduction

The cost of manufacturing ammonia using the Haber process plant constitutes the following components: the cost of energy, raw materials, equipment, labor and sparking substances (catalysts). Energy (gas or electricity) costs are incurred to maintain the temperature of the reaction. The Harber process is operated at very high temperatures, and pressures thus higher costs of energy are incurred. Some of the raw materials consumed in the Haber process such as nitrogen and hydrogen are recovered at the end of the process. The recovered materials are recycled back to the system to reduce the cost of raw materials. Starting and ...

An acid is a solution that loses hydrogen ions. Common household acids include vinegar and citrus fruit juice. In contrast, a base is a solution that gains hydrogen ions. Acidic substances often taste sour whereas bases taste bitter and feel slippery. Since the tasting or touching of acids and bases can be harmful to human health, Occupational Safety and Health Administration (OSHA, 2013) recommends the use of indicators to test for the acidity or alkalinity of substances. Typically, indicators such as litmus paper change color when exposed to acids or bases (Stanley et al., 2015). As such, the present ...

Peroxisome is one of the membrane organelles of the eukaryotic cell. It is a small (about 0.2 – 1.5 micron) elliptic body bounded by a membrane. The core of the peroxisome is often made of the crystal-like structures. They located in the center of the organelle and are covered by granular matrix. Peroxisomes exist both in plant and animal cells; their amount varies between 70-100 organelles per cell. In humans and mammals the highest concentration of peroxisomes is found in liver and kidneys. Detoxification is one of the main functions of this organelle. It contains the enzyme called catalase that ...

Sulfur dioxide is considered one of the most harmful contaminant present in our environment today. It not only pollutes the land, but also pollutes water and air. The main reason for its contamination is the acidic nature it possesses. When sulfur dioxide combines with the surrounding water, it forms Sulfuric acid, which damages the soil, and hence affecting the plants which grow in this soil. On the other hand, Organic pollutants such as hydrocarbons are not very harmful because there are no acidic components in it. These pollutants decompose naturally and give of water, which causes no harm to ...

Part 1: Answers to Preliminary Questions

• Photosynthesis is the process by which green plants use sunlight energy to manufacture food using water and carbon dioxide as raw materials.

• An increase in the intensity of sunlight increases the rate of photosynthesis up to a given level.

• Photosynthesis and respiration processes complement each other. It is possible to examine the relationship between photosynthesis and cellular respiration under controlled experimental conditions. This can be conducted by setting up an experiment with two sets of experimental set-ups. In each set-up, there should be two test-tubes: one with a high concentration of carbon dioxide and another with a high concentration of oxygen. One pair of test tubes, consisting of a test-tube with a high concentration of oxygen, ...

Introduction

Coal is a very cheap and abundant provision of energ. In fact, it is the most abundant fuel in the United States; U.S. has the highest coal reserve in the world, with up to 25% of the known world coal present in America and being mined in 26 out of the U.S. 50 states (fe.doe.gov, 2013). However, this abundant energy is seldom used because it is a very dirty energy. According to Hong & Slatick (1994), up to 204.3 pounds of carbon dioxide per million Btu is emitted when coal having 78% carbon content is completely burned to attain a ...

Abstract

The concentration of carbon dioxide has been abnormally increasing over the years. In the year 2016, its concentration exceeded the limitations, and has been considered as a dangerous situation. As a response to the increasing carbon dioxide content in the Earth’s atmosphere, different processes are being suggested in order to lower the concentration. Carbon Capture and Storage, or CCS, is one of these processes. Generally, there are three different phases of this process: the pre-combustion, the oxyfuel, and the post-combustion. These three phases have different processes in which the carbon dioxide content is being separated from the other ...

Introduction

Sickle Cell Anemia or Sickle Cell Disease is an inherited blood ailment. Those suffering from Sickle Cell Disease have abnormal S/ sickle hemoglobin in the red blood cells. Hemoglobin is the protein in the blood that aids in carrying oxygen throughout the body. The ailment takes its appellation from the shape of the red blood cells of a person affected by Sickle Cell Disease, which have the shape of a sickle. They are stiff and adhesive rather than a disk like normal cells. The misshapen cells tend to get trapped in the small blood vessels hindering the movement of ...

Introduction

Urban sprawl has turned out to be a controversial issue in recent times due to the rate at which green spaces are disappearing in most of the cities, especially in the United States. Nnaemeka-Okeke (2016) describes urban sprawl as the expansion of a community devoid of concern for the environmental impact. In other words, urban sprawl is the uncontrolled expansion of the metropolitan areas. This phenomenon primarily results in the extinction of green spaces and a variety of environmental consequences. Banai and DePriest (2014) maintain that urban sprawl is considered a cause of the climate change, with environmental effects ...

Global Warming Phenomenon

The issue of global warming has been a critical problem across the entire world due to the effects associated with this condition. Global warming is caused by the increase in Earth's temperatures due to the effect of greenhouse gases. The greenhouse gases, such as carbon dioxide emitted from burning of fossil fuels like coal, oil, and natural gas to provide energy are responsible for trapping heat and preventing it from escaping from the Earth’s atmosphere. Human activities like cutting down trees and burning forests for farming activities has been attributed to the emission of greenhouse gases that are ...

Bacteria refer to the regnum of prokaryotes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan). For the current moment, it accounts for more than ten thousand kinds of bacteria. The bacterium is recognized as one of the most ancient of living organisms, arising about 3.9 – 3.5 billion years ago. Bacteria have the substantial variation in the ways of metamorphic and energetic metabolism. Thus, autotrophs can synthesize all necessary organic molecules from non-organic compounds, whereas heterotrophs demand active organic compounds to transform them. The biggest degree of heterotrophs belongs to intracellular parasites. They are called saprophytes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan) and can ...

Can he change the geographic lines of the different AQCRs so as to attract more industry? How?

It is the responsibility of the states to designate the location of the AQRCs after confirming with the national government. In perspective, I would advise the newly elected governor to petition EPA to relocate and redraw the geographic lines of AQCRs. The directions of this proceeding must, however, align with the requirements of the federal government, which implies that due consultations must be made before placing the modifications. Usually, revisions of the placements are approved to SIP depending on its estimated effects and results expected from the new locations. In this case, the governor wishes to relocate in order ...

Introduction

Global warming is defined as “the rise in the average temperature of the Earth’s climate system and its effects” (Gills, 2015). There are various strands of scientific evidence that reveals that the climate system of the earth is indeed warming. Today, the scientific comprehension of global warming is expanding. A substantial amount of research has been done on the matter. However, there is still a debate going on about global warming. One side emphasizes the cause of global warming as human or anthropogenic activities, and that there is a need to mitigate the effects of global warming – that ...

Introduction

According to Alexander (2014), the oil sands of Alberta have around 1.7 to 2.7 trillion barrels of bitumen reserves. The recoverable oil resource in Canada is second only to that of the leading oil producer, Saudi Arabia. The vast oil reserves are capable of supplying Canada’s energy needs for over 500 years. Presently, nearly 40 percent of Canada’s oil production is generated from the oil sands (Alexander, 2014). They comprise mainly of bitumen mixed by sand and water. Alberta’s major oil sands are located in Cold Lake, Athabasca, and Peace River. Different deposits and areas have ...

Introductory remarks

With the depletion of crude oil deposits across the world becoming a reality with every new day, the world has been forced to start looking at alternative sources of oil. One of these unconventional sources of oil is the bitumen oil found in oil sands. Canadian oil sands have been identified as the second largest oil reserves in the world after those in Saudi Arabia. Most of these oil sands are found in the province of Alberta. These oil reserves are estimated to be an approximate 175 billion barrels of bitumen and sit across an area of 140,800 ...

Landfills are a necessary evil that only deserves to be properly managed in order to avoid related problems. Human life will be more difficult without places they could dump their waste, especially given that the Environmental Protection Agency (EPA) puts the rate of average dumping at 4.5 per person. Landfills are directly related to population, in that, as the population grows, landfills increase in number and size. Other than the fact that human beings are generally not willing to live near them, landfills are also very ugly and cause environmental problems. These problems occur through Leachate, Toxins, and Greenhouse ...

The “new” moment in this article was the fact that the company needed to change working processes on its utilities to complain to the Clean Air Act. The Georgia Power’s Bowem plant looked like a “unique” object. The plant was quite big with its ability to “produce enough power to serve the residential, commercial, and industrial demands of 1 million people” (Harvard business school, 1993, p. 1). However, it was quite clean and had fewer emissions than smaller objects; it was a unique feature because of plant’s size and age. Amendments to the Clean Air Act were ...

Cellular respiration equation:

C6H12O6+6O2→6CO2+6H2O+38ATP. Glucose+Oxygen→Carbon dioxide+Water+38ATP.

Photosynthesis equation:

6CO2+6H2O+sunlight, nutrients→C6H12O6+6O2. Carbon dioxide+Water→Glucose+Oxygen. Respiration and photosynthesis are opposite processes. It means that products of cellular respiration are reactants of photosynthesis and vice versa: the products of photosynthesis are reactants for cellular respiration. It is known that plants are autotrophs. Thus, they have to realize cellular respiration because they need energy for their existence. Due to cellular respiration, they receive energy, which is used to make organic compounds (glucose) and oxygen during photosynthesis. From the other side, people are heterotrophs. They ...

Climate change, in contrast to what a surprisingly large segment of the public thinks, does indeed pose a significant threat to the way that we live. What makes a thorough understanding of the dangers of climate change is the fact that its effects are rarely large, one-time calamitous events, such as a terrorist attack; but rather slow persistent changes, like a small leak in a boat that, while dangerous, lull people into the belief that nothing is happening or that the situation is manageable. In addition, as Newton theorized in his third law, for every action there is an ...

Global warming is caused by the buildup of greenhouse gases (i.e. Carbon Dioxide, Nitrous Oxide, Methane, and Halocarbons) which are gradually making the planet hotter as more and more heat is retained which cannot be reverted easily. Global warming is also happening because of the continuous burning of fossil fuels and the reduction of carbon dioxide sinks (i.e. forests).

The current level of carbon dioxide in the atmosphere is 384 parts per million.
