Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

Algae are a diverse group of organisms that are mainly autotrophs. Autotrophs are organisms that mainly produce complex organic compounds by using simple inorganic molecules and light or in other instances by chemical reactions. Algae can be broadly classified into two main groups which are unicellular or multicellular. Seaweeds form the largest and most complex marine type of algae (Olanrewaju, Wan Nik, & Kader, 2013). It should, however, be noted that algae can further be classified in many different ways. Below is an illustration of some of these classification representations.
Green algae are classified into the Plantae kingdom and are, ...

(3 Points) What is the biological pump as it relates to the ocean?
The process of obtaining carbon dioxide molecules from the atmosphere is influenced by the biological pump. This pump increases the carbon dioxide molecules in the deeper parts of the ocean which results to the decrease in the atmospheric carbon dioxide by turning and incorporating the carbon dioxide molecules into living matter or phytoplankton. Upon fixation of the molecule into the phytoplankton, the organism starts to descend to the deeper levels of the earth due to gravity (Earth guide, n.p.).

Climate change is one of the biggest challenges facing humans. Individual’s lifestyles have developed to such an extent in developed countries that people continue to drain the earth of fossil fuels used to sustain humans. The result is that global warming is happening as a result of natural but predominantly human activities that release carbon emissions into the atmosphere. Measuring the best forms of energy to counteract this depends on a number of technological, economic and societal variables. It also requires the efforts of government to use command and control along with economic incentives to the highest potential for each ...

Abstract

Recently, attention has been diverted to clean, alternative and renewable technologies due to the depletion of petroleum resources and increase of the green house gases from the combustion of fuel resources. Fuel cell is the fore-runner of these technologies and has received immense impetus due to its relatively clean source of energy. Fuel-cells are devices that produce electrical energy from chemical transformation reactions. Electrodes are placed within an electrolyte medium that facilitates oxidation of fuel. In these electrochemical reactions, ions are generated that generate electricity. This electrical energy can be effectively harnessed to carry out a myriad of functions. Since ...

Causation of Climate Change

The world’s climate system is composed of five elements that include hydrosphere, lithosphere, atmosphere, cry sphere, and biosphere. It varies naturally with time and is dependent on the incoming and outgoing energy which determine the optimal balance of the earth’s energy. These determinants constitute factors that cause climate variation that result in either warmer or colder states. This result into a phenomenon referred to as climate change. This is a condition, in which, the earth experiences adjustments in its weather that occurs over a period. This essay provides a detailed analysis of the causes, characteristics, and the impacts of climate change ...

Introduction

This term paper explores the issue of weather affecting pollution in major cities. In a major city, where there can be a higher proportion of pollution sources in a relatively small geographical area, the effects are likely to be more distinct and concentrated.
Whilst there are several causes of air pollution, it is known that the air quality at any given time can be affected by the prevailing weather conditions. For example, strong winds can rapidly transport pollutants released into the air great distances from the originating source. Conversely, in conditions when there is very light wind or in still air, the ...

1. Components and mechanisms of the respiratory system
The respiratory system is the system that allow humans and animals to breathe. The main function of the system is to provide oxygen to the body through the blood. Breathing involves two main actions: inhaling and exhaling air. Inhalation brings oxygen into the body via the blood and exhalation chases out carbon dioxide.
The respiratory system is composed of different tissues and organs, including the airways, lungs, bloods vessels and muscles connected to each other to assure a proper breathing process (National Heart, Lung and Blood Institute, 2012). The airways ...

A reality that has been always considered a hoax by many as they believe global warming is because of the changing nature of the Universe and how the planet rotates. Global Warming is real because while it could be naturally influenced, the concentrations of the greenhouse effect emmissions causes the rays of the Sun to remain on earth, further influencing climate.
The dispute that rages over this issue is unresolved because “experts” have shown “proofs” (for and against) based on scientific data. Supporters of the non-existence of Global Warming, basically offer the arguments as that the climate has changed ...

Introduction

As a matter of fact, air pollution is one among the primary health menace in the urban environments of many countries – both developed and developing. The aspect of air pollution is associated with congestion of human beings, vehicles and factories of the power. Currently, the United Nations, in conjunction with various governments across the globe, is trying to protect the human race through reducing air pollution, with the greater purpose of saving the ozone layer – the protective natural cover that filters the dangerous ultraviolent rays of the sun. Currently, many cities have come up with policies to help curb the ...

Travelling to another planet is referred to interplanetary spaceflight. The term is usually used when travelling to a planet within the same planetary system (Fisher 1). The human race has made tremendous strides in space exploration. Man has made it to the moon and back, which was a great achievement for science as well as the human race. Man may not have stepped onto another planet yet, but significant achievements have been made in interplanetary exploration. There have been explorations using probes that have flown by every planet in the solar system. The New Horizons recently flew by the ...

Global Significance
The one environmental issue that has the most important significance in the world today is global warming. That is because the rising temperatures at the surface of the earth are responsible for causing negative impacts around the world. The two general causes for global warming are (a) natural and (b) manmade. Green house gases are causing the warming because the amount of manmade greenhouse gases added to those that are formed naturally have created the problem of too much trapped heat in the atmosphere. The sun’s energy plus reflected energy from the surface of the earth becomes ...

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 ...

The agenda for population and development seeks to establish the knowledge of how population and social, economic, and environmental change relate to each other (Finkle, Jason, and McIntosh, 1995). By so doing, a forum for discussion of the related matters is created. Population and development exercise is the enhancement of personal opportunity and freedom. It’s inherent in member states of the United Nations to attain universal human rights and dignity for their citizens (Martínez, Rodrigo, and Andrés, 2007). It’s a representation of aspirations of the governments to ensure that all individuals are free from fear, ...

Comparison of the Landfill Facilities

This paper will compare two landfills; the Landfill Gas Capture and Flaring Facility in Alexandria and the Bantar Gebang dumpsite in Bekasi.
The Landfill Gas Capture and Flaring Facility in Alexandria is used to contain the solid waste from four districts within the Greater Cairo in Egypt. However, the dumping site could not meet the minimum measures for pollution management prompting the Alexandria Governorate to hire a corporate that could ensure effective solid waste control in the area. The solid waste on the landfills at El Hammam and Borg El Arab give out methane which when emitted to the ...

The movement from sites of waste-disposal of contaminated groundwater is a problem faced by many cities in world. Solid and liquid waste dumped in landfills generates an atmosphere where inorganic and organic compounds present in the water or which are produced in the landfill become prone of entering the hydrological regime through movement. The movement of contaminants in water bodies through landfills is more distinct in temperate and humid climates as penetration of rainfall is moderate to high, and separation of leachate from the aquifers which are underlying for extended time periods becomes a complex process. In such areas, landfills gets ...

Introduction

Our environment of late has become a scarce resource. Economics being a discipline concerned about effective utilisation and distribution of scarce resources is therefore vital when addressing environmental problems. When formulating environmental policy, economics comes into play with the aim of balancing the costs and benefits of the environmental measures. In this essay, I will discuss air pollution as an environmental problem and the economics involved in addressing it.

Air pollution and Trends in the last 20 years

According to EPA there are six major pollutants that determine air quality. They include: lead, carbon monoxide (CO), nitrogen dioxide (NOx), sulphur dioxide (SOx), particulate matter, and ozone.

Asthma is a chronic inflammatory disorder that causes shortness of breath, a feeling of tightness in the chest, and persistent cough. There are two primary types of asthma: intrinsic and extrinsic. Intrinsic asthma comes about through non-allergic means: cigarette smoke, stress, cold air, cleaning agents – basically anything that does not involve an allergen. Extrinsic asthma, on the other hand, comes about through an allergen such as dander, pollen or others. It leads to a constriction of the airway during an attack, leaving the victim out of breath, unable to take in more air, and with a tight feeling in their chest. In this ...
