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 ...

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.

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 ...

3-nitrooxypropanol Report

Introduction Sheep, cattle, goats, and some wild animals such as antelopes and their families that are predominantly known as ruminants ferment plant material in their rumen. The result of this fermentation process is the formation of propionate, CO2, acetate, butyrate, and methane (Alexander et al., 2015). The carbon dioxide and methane formed escape from the bodies of these animals into the atmosphere.3-nitrooxypropanol is believed to inhibit methanogenesis in ruminant, an action that has various applications and benefits to the environment and animals. This report will consider the need for and application of the 3-nitrooxypropanol and how it would work ...

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 ...

Air contamination has emerged as one of the most critical problems affecting the realization of a sustainable community, especially in urban areas. My community, in particular, is a victim of this circumstance and strategies are being put forth to curb this problem. Air pollution ...

Fuel Cell Technologies in Passenger Cars

Fuel Cell Technology The last decade is characterized by the rapid development of research activity in the field of fuel cells, thus, creating the conditions for their uptake in electric systems. The basic fuel cells’ operating principle has been known for 150 years. However, a variety of technical and financial problems had kept them on the margins of technological applications (Brandon & Hart, 1999). The basic difference between a fuel cell and batteries is that while batteries store energy, fuel cells directly convert a fuel’s chemical energy into electricity by an electrochemical reaction (i.e. Without requiring combustion or movement ...

Improved scientific understanding in recent years has shown that humans are the major causes of climate change on the planet. A report released by IPCC (the UN Intergovernmental Panel on Climate Change) in 2014 reports that it is “extremely likely” that the dominant cause of global warming in the 20th Century is the influence of humans. Human activities over the last two hundred years, since the beginning of industrialization, have caused a building up of greenhouse gases in the atmosphere, and as a result, the Greenhouse Effect (a natural phenomenon which regulates the temperature of the earth) has increased ...

Windmills have been widely used since thousands of years to pump water for agricultural purposes, propel ships and grind grains. As civilizations advanced, other convenient sources of energy replaced wind energy. Currently, fossil fuels that include coal, oil and natural gas fulfill the energy needs of nations across the world. These fuel sources are responsible for polluting the environment through the emission of hydrocarbons that cause global warming and various other environmental hazards. Also, these non-renewable energy sources are much limited and continue to deplete from the face of the earth. Therefore, wind energy that can be tapped conveniently ...

Is Climate Change Caused by Human Action

Introduction Are humans responsible for climate change? While it is evident that climate change is a result of different factors which when combined produce a hazardous effect, human action is considered to be the main cause of global warming. Numerous studies show that various human activities produce gas that traps heat which results in most of the increase in globally averaged temperatures. Clearly, atmospheric warming and cooling did not begin with people. It used to occur long before the rise of humankind through natural activities, such as volcanic eruptions, changes in the sun’s intensity and the already existing ...

Global warming and climate change are two different terms that have been used over the years to describe different phenomena. Global warming refers to a subsequent increase in the global average temperature (Black & Weisel 5). On the other hand, climate change refers to global climate changes due to increasing average global temperatures brought by changes in rain patterns, increased drought and heat waves. These future projections in the change of global rainfall patterns can be derived from the Intergovernmental Panel on Climate Change (IPCC) reports over the years. The argument that the use of term global warming has been ...

Materials Extraction

These batteries consist of heavy metals such as cadmium, mercury, zinc, and nickel, which are environmental pollutants. Hence recycling them instead of incinerating them together with household waste saves our environment. These valuable metals are recovered during the process of recycling and consequently, save energy by minimizing the use of raw materials. Several materials are extracted from the used batteries and are used to manufacture new ones. Manganese dioxide, which is normally used to catalyze the reaction that produces oxygen from hydrogen peroxide, is contained in the zinc carbon cell. Dry batteries also contain metallic zinc, which is usually ...

Besides pressure from the international community, the US has had to respond to numerous challenges powered by carbon emissions. The country's electricity sector contributes the largest portion of carbon emissions followed by transportation, industries and residential places. The state also loses more than $100 billion every decade ...

The ozone is a layer of gasses in the stratosphere that protects life on Earth against ultraviolet rays from the sun (Aggarwal et al., 1). Anthropogenic activities leading to the emission of nitrous oxide and chlorofluorocarbons can result in the destruction of the ozone layer. Organohalogens also contributes to the destruction of the ozone layer (Lee, 858). The depletion leads to secondary ozone layer close to the ground called terrestrial ozone layer that is responsible for the degrading effects on humans, plants, and their environment. In the article published on August 27, 2009, on the New York Times, Dean ( ...

Problem statement

Azerbaijan like many countries in the world is dependent on fossil fuels as a source of its energy. Being a fossil fuel rich country, fossil fuels are widely used to produce majority of the energy needed in the country. However, fossil fuels have a number of problems associated with them. They are a finite resource and human beings are using them at a much faster rate than the earth can replace them. Therefore, in the future humans will deplete all natural occurring fossil fuels (Michaelides, 2012). Furthermore, carbon compound makes up fossil fuels. This implies that burning up fossil ...

Air pollution involves the introduction of particulates and other biological molecules in the atmosphere, resulting in the death of humans, other living things and damage to other resources such as crops. It involves the interaction of different pollutants which eventually affect the environment, health, and even the climate. These pollutants are emitted almost from all economic and social activities. The most cases of air pollutants are; Sulphur Dioxide, Nitrogen Oxides, Particulate Matter, Ozone, Ammonia, Non-methane volatile organic compounds, carbon dioxide, lead, heterocyclic, chlorinated hydrocarbons, phenol and Methane amongst others. Emission of many air pollutants has decreased across Europe as ...

Global warming is one of the key threats in the world. Global warming is a real phenomenon that is affecting human existence. Scientists assert that that global warming is on the verge of destroying all species on earth if the trend continues. Global warming entails the increase in average atmospheric temperatures in the earth that causes corresponding changes in the climatic conditions. It is the projected and observed increase in average temperature in oceans and Earth atmosphere. There are various causes and effects of global warming. The causes of global warming are linked to the effects and changes in ...

Energy is one of the most important components of our day to day activities. Gasoline, diesel, kerosene, propane and other products are extracted from fossil fuels through a number of systematic processes and are used to drive automobiles, aircrafts, ships and trains. Despite their importance, these fuels lead to the emission of greenhouse gases into the atmosphere and results in global warming, which has been on a steady rise for quite some time. A few Economic Crises have occurred in the recent past due to depletion of oil reserves. The latest brands of hybrid and electric cars are the ...

What makes it so pronounced is the threat it poses to a large portion of the earth and generations to come. New York City, Norfolk, Va., Venice, Bangladesh, Indonesia, the Philippines, ...

ABSTRACT

The research argues that although a gas flaring stoppage is not successfully in-place in Nigeria, fitting the appropriate technology with complementary economic and institutional factors can lead to near-zero or zero gas flaring. Nigeria is a developing country with a unique culture of many tribes and one of the largest growing urban populations in the world. Infrastructural, political and economical challenges to meeting the goal are introduced. Reinjection of gas back into wells is not available as an option to gas flaring because a large region for gas production is wetlands (Buzcu-Guven et al. 2012). Wetlands ...

Abstract

Carbon Capture and Storage Technologies (CCS) is a technological method that is used to reduce the emission of carbon dioxide into the atmosphere from a variety of sources including industries and fossil fuels production and power sources. This type of technology involves the capture of dioxide either after burning or before burning and then transporting via ships or pipelines and then directing it into the deep underground for storage purposes. This type of technology has been in existence since the 1970’s and has rapidly evolved over time. In fact, the increased impact of the greenhouse effect due to increased amounts ...

The U.S. Government’s and Individual Citizens Obligation in Reducing Nation’s Greenhouse Gas Emissions

The question on whether the United States government has an obligation to adopt policies that are designed to reduce the nation’s greenhouse gas emissions is of great controversy. This is due to the approach that is taken by different individuals to try and look into this question. The answers given by various personalities vary based on the approach that is taken towards this matter. This is despite the common knowledge that all individuals have a role in reducing greenhouse gas emission. This is ...

INTRODUCTION

The wider population and the government are aware that prompt action is necessary to lessen the human impact on the environment, which is the means to turn around the global climate changes as well as lessening the demands on natural resources. Much has been done concerning this issue but a lot more needs to be done in order to decrease consumption of resources and get better environmental management if we want to repeal the global climate change and spare some resources to the future generations. Humanity is running out of natural resources and the global climate change is not something ...

Just as James Lovelock once said, “We live at a time when emotions and feelings count more than truth, and there is a vast ignorance of science”, it is true that in this age it is increasingly important to listen to the scientific facts, as science is the best tool we have to discern whether or not climate change is caused by mankind. The term “anthropogenic” is used to describe human-made climate change and means originating in human activity. Climate change is defined in the change in global climatic patterns since the mid-20th century and is not limited to ...

United States of America has used oil as its main source of energy for a long time but, it can emulate the Simso community project. This because, however, they have ready access to oil in the state, the oil is a major source of global warming that leads to climate change. The Simso community initially used electricity that was coming mainly from the mainland that was passing through a cable and generation coming from coal. This affects the atmosphere as carbon dioxide is generated through the process in tones. For example, each sassing into the atmosphere generates almost eleven tones on an ...

Introduction

Currently, coal-fired power plants account for more than 80% of carbon dioxide emissions in the electric power industry of the United States and 33% of all the carbon dioxide emissions in the United States. Consequently, reducing carbon dioxide emissions that come from the coal plants is the focus of most proposals that intend to cut on the greenhouse gas emission. The options to do this include capturing and sequestering carbon dioxide that emitted by the coal power plants, replacing the coal power plants with the low or zero carbon dioxide sources of power like the nuclear and wind energy.

Science Lab: Greenhouse Gas

1. From 2012 to 2050 (in thirty eight years) the temperature rise was faster from greenhouse gas then the rise in temperature from 1750 to 2012 (in two hundred sixty two years). In 1750 the sources of greenhouse gases were methane from the cows’ manure and other natural sources, very few greenhouse gas molecules were trapped. Then the Industrial Revolution started a big change. The coal burning factories emitted air pollution containing greenhouse gases straight into the atmosphere. More and more factories were burning fossil fuels without trapping the GHGs before they left the smokestacks. Pollution enters the atmosphere ...

Introduction

There are many advantages to designing a building using economically and environmentally sustainable methods. Although “green” construction materials and technologies cost more in the short term, in the long run green strategies have been shown to save money. By “going green,” the owners of the building will enjoy lower utility bills and higher resale values later on. More efficient heating and cooling will not only save on costs but will be less taxing on the environment. The key to effective green building has to do with the performance and cost trade-offs associated with the different design methods. As an example, ...

Certain elements involved in the geochemical and biogeochemical cycling are of great concern due to their limited availability both naturally or through industrial manufacture of the compounds involved in the cycles. Some of the processes involved are chemical reactions with other elements or substances. Some of these reactions are irreversible chemical reactions. This implies once the reaction has taken place, the elements are removed from natural cycle and they cannot be replaced again. As such, the more the cases of irreversible reactions, the greater the rate of reduction of these elements from the environment. Ultimately, there could be less ...

Safety in the industry is as much important as production itself. It underscores because industrial safety system, usually known as Integrated Control and Safety System (ICSS), is an integral part of most industries. Industrial safety is targeted at providing protection against menaces, risks and hazards which can occur in different forms, in the industry. It is, however, not intended for controlling only the hazard. Process control systems are rather provided for controlling the hazards. This essay takes a brief look at what safety in the industry is and also its correlation to public health. Virtually every industry has its ...

- What causes climate change? Define the Greenhouse Effect

Greenhouse gases (GHG) allow sunlight to enter the atmosphere and absorbs the heat produced by that light. Most of this heat energy is trapped within the atmosphere by the GHG while some of them are let out into the space. The phenomenon of atmospheric heating due to the GHG is called as the greenhouse effect. Gases such as carbon dioxide, methane, nitrous oxide and fluorinated gases form the greenhouse gases. Burning of fossil fuels, manufacturing processes, decay of organic matter, agricultural industries and emission of synthetic fluorinated gases from various ...

Energy remains one of the most essential elements of necessity in the modern dispensation. Most industries and people rely on the different forms of the energy for production or a different use. Many people use electricity in the homes not knowing where and how electricity comes into play. The many companies that use the forms of energy consume the highest amount of energy. The videos show people using the energy as a means to an end. While energy is an important aspect of the daily lives, there are some challenges that come with the different forms of energy.

Global warming is probably among some of the most major issues that our planet and its inhabitants are facing. Indeed, the phenomenon has some very alarming effects on agriculture and on animals, and it has even more frightening effects on the human population. The media and politicians are often heard debating over the fact about global warming. However, even though there is widespread disagreement about the causes, but the reality of the global and measurable effects of global warming cannot be denied. The fact of the matter is that, it is the human race is the source of the ...

There is a serious debate on global warming in academic and media circles. The internet and media are my main sources of information on this issue. In addition, I have witnessed infrequent flooding and droughts which I associate with global warming. I am concerned because this phenomenon poses a lot of danger to current and future generations of humanity as well as flora and fauna. The increase in atmospheric carbon dioxide is worrisome because it contributes immensely to the heating up of the earth’s surface. The concomitant rise in temperature leads to melting of polar ice and jeopardizing of ...

Global warming is mainly a process that uses the atmosphere of the earth as a blanket to hold energy from the sun to heat the air. As of now the global warming process has made the earth’s atmosphere hotter up to around 60 degrees Fahrenheit compared to the latter years. The effects of global warming are being experienced throughout the earth with increased temperatures and irregular weather patterns. The world has undergone several climatic changes over the past centuries. These past changes occurred slowly ranging over a period of hundreds of thousand years, but the process has been moving much faster ...

The president of the United States of America is required under Article two of Section three of the United States Constitution to give a state of the union address to the nation. It is usually delivered once a year in January or February. The tradition began in 1790 when George Washington delivered a State of the union address before a joint sitting of the congress, usually in the House of Representatives. Thomas Jefferson discontinued the tradition, arguing that it was too monarchical in nature and it was replaced by a written report by the president. In the twentieth century President Woodrow Wilson re-established the ...

The issue of energy conservation and the search for new, cheap, renewable energy sources has taken center stage in politics and science in recent years. The different types of renewable and sustainable energy sources are very varied, and each have different advantages and disadvantages. However, before discussing the different advantages and disadvantages of renewable energy and renewable energy policies, it is important to first discuss what type of energy is being discussed under the umbrella of “renewable” or “sustainable” energy. First, solar energy is one type of energy that is commonly considered to be a renewable energy source, since the ...

- While conducting research, scientists need to understand the main variables within their experiments. Define and provide an example of both an independent and dependent variable. In any research there are mainly two variables; the independent and the dependent variables. Any scientist needs to understand the variables very well because of the following reasons. First the variable determines the type of methodology that can be used in the study. What this means is that the type or variables would determine how the whole research is carried out. For example, a variable might have qualitative or quantitative aspects that would ...

It would be tough to choose between the positives and negatives of an electric car, because along with the number of positives it carries, it does have its share of negatives as well. However, going by the popular view that with gasoline depleting and carbon emission increasing, electric cars would be best suited for modern transport; the positives undoubtedly outnumber the negatives. As the world population grows, the need for housing and food has slowly by surely started eating into the forests, and man finds himself fighting for space with animals. As growth has to be supplemented by development, ...

The globe is facing a severe environmental crisis of its kind in this 21st century. The major environmental hazard that has shaken the world at the moment is air pollution.

However, even nowadays, the negative impacts of this environmental crisis are evident in all forms. These impacts range from growing deserts due to lack of enough rainfall, increased cases of cancer, majorly lung cancer as a result of unclean fresh air and lastly the loss of numerous plant ...

Is global climate caused by human activities?

Currently, the question on whether human activities cause global warming has sparked debates from environmental experts. The massive growth of the population has increased growth of consumption, and this poses threats to the global climate. The rise of the earth’s temperature is mainly caused by the gases released by greenhouses, especially carbon dioxide. It is saddening to note that the climatic changes affect the physical and biological systems across the universe. Global warming can only be decreased if the carbon output released by human activities is reduced. The Journal of Climate published a paper by Jara Imbers, Chris Huntingford, ...
