These natural communities in which varieties of living species exist are referred to as Biodiversity. Biodiversity thus encompasses all the plants and animals in a habitat and all the processes therein, which sustain and support their life and enhance their chances of survival.

This assessment is important due to the fact that life in such ecosystems has been endangered by increased pollution. Sources of pollution in aquatic environments include wastes from industries, sewages and chemicals resulting from farming activities. Therefore, the assessment of the health of aquatic environments is essential in order to determine the quality of water and whether that water can support life.

It is still a new area of much controversy and continuous knowledge and information are emerging at a fast pace. The anthropocene is a geologic era that seems to be manifested by human behavior. Human beings have continued to exert pressure on landscape in so many diverse ways.

While many other politicians, thinkers, and analysts may believe that the world is overwhelmed with other threats and concerns, the issue of global warming should have a priority because it has the potential of affecting the whole world, not just a country, a region, or even a continent.

Wave Kinetics and Tidal Energy as an Alternative. The law of conservation of energy states, “Energy can neither be created nor it can be destroyed, it can be transformed from one form to another” (Denecke 2006). If we look around, we can find many resources of energy like the fossil fuel has the chemical energy stored in it and when it is burnt, the chemical energy transforms to thermal energy, which can be utilized for majority of purposes.

This particular study focuses on the pathway of the states of New York alongside Pennsylvania in the writing of parametric policies that will regulate the oil-drilling operations and at the same time to protect the public safety by ensuring prevention of contaminating the water supplies and precluding some other side effects of Hydraulic Fracturing from taking place.

Perhaps, the most striking of all the points that do add weight to the statement that human activity is the chief culprit, in terms of enhanced global warming, is the drastic rise in the greenhouse gases. And it is a universally recognized truth that, over the years, it is the various activities of people that have been leading to increased greenhouse emissions.

Dioxins are a group of harmful chemical compounds that significantly affect the ecosystem negatively. The justification for a detailed analysis of this chemical compound has been necessitated by the risk factors involved. These factors have been mainly reported in the United States.

This is due to the fact that man indulges in activities without reminiscing at the probable consequences. Because of this, science has found it way in guiding man on what is advisable to do after weighing out on their benefit and costs. For instance scientists have been on the forefront in making sure that before a project is commissioned, no matter how beneficial it might prove to be, it’s possible environmental impacts must first be carried out and assessed (Yankelovich, 2011).

It is clear that geographical ranges majorly depend on several structural and physiologic adjustments undertaken by a species. In certain cases, the species finds these adaptations quite suitable in a place that is different from the location where the species evolved in the beginning (Niche and habitat - MarineBio.org).

Water contamination is a serious issue of concern (Gleick, Allen & Cohen, 2011, p.285) among individuals since the contamination of drinking water has significant impacts on the health of human beings. The water supplies are responsible to test the water that they supply to the common people such that they are free from impurities and contain minimal amounts of contaminants.

These cities serve different functions apart from basically having the same basic structures and provisions. Cities can serve main purposes such as administrative, economical, transit or technological. It is estimated that over 85% of the world’s population will be living in urban areas by the year 2050.

Bioengineering in Food Bioengineering vs. Hybridization Bioengineering is also known as genetic engineering, a modern technology that is often applied in medicine and agriculture. Genetic engineering is a process that includes the identification and incorporation of economically valued genes into a specific crop, the introduction of the desired gene into the recipient cells through a delivery system, and the expression of the new genetic information in the recipient cells (Lutz, 1999, p.

Lake Erie used to be full of all kind of fish. The lake was greatly used for commercial fishing and as a tourist spot for vacationers. After colonization the human development that took place in that region had a great impact on this lake and the creatures that live in it.

The remaining 10% is shared between other heavier hydrocarbons: ethane, propane and butane. During its extraction, propane and butane gases are removed from the natural gas to form Liquefied Petroleum Gas (LPG). LPG is distributed to those regions where natural gas distribution through pipelines is not possible, due to economic reasons.

Use of Ethanol as a Fuel Automobiles are considered a big threat for environment since they cause a lot of pollution and damage in terms of air and water pollution. The automobiles derive the power for running by burning the fuel in its engine. The evaporation of fuel itself and the by-products that are released due to burning through the exhaust are major air pollutants.

This essay will explain sun and its impact to world’s global warming. The Sun The sun is the core of our solar system. It’s considered as the biggest star in our galaxy with 1,390,000 km. in diameter and a mass of 1.989e30 kg. (Nineplanets.org, 2012).

Bio-energy is a resource that has become increasingly significant as an energy carrier in the modern society. Throughout history, in all its forms, biomass has been one of the most important source of human’s basic needs often referred to as the six “fs” namely feed, food, feedstock, fuel, fertilizer and fiber.

Energy is used in nearly if not all aspects of life especially in modern days when technology is touching nearly all aspects of human life. Energy is used in lighting, to power automobiles, planes and trains, to cook, power factory machineries and tractors, and to power entertainment equipments among other uses (Twidell and Weir, 2005).

Even though it may be difficult to precisely put down the meaning of the sustainable communities, there are some of the known qualities worth inclusion in the definition putting into consideration the context in which the word is widely used. According to World Commission on Environment and Development 1987, sustainable development is the kind of development that is capable of achieving the present needs without compromising the future generation’s ability to achieve their own needs.

According to Greenhalgh, Sales, and Emmel, it is difficult to recruit socially excluded individuals and groups into research studies. They further observe that researchers face difficulties in recruiting and obtaining information from this group even in cases where studies are explicitly designed to seek the values, opinions, and experiences of the socially excluded individuals and groups.

Global warming has proved to be a vital problem in the scientific world and has tremendously and adversely affected the climate of the world and in particular the United States of America (Johanes, 2004; Brooden, 2007). Global warming is majorly caused by the upsurge of the amount of carbon dioxide in the atmosphere due to the increased emission of carbon gases in to the atmosphere.

Technology has been defined by Oxford Dictionary as “scientific knowledge used in practical ways in industries”. Scientific advancements in various areas have helped the development of technologies which makes the application of science user friendly. There has been technological innovation all through the history of mankind.

This follows realization that continued use of fossil fuels leads to accumulation of greenhouse gas blamed for climate change. The first commercial wind farm in UK was commissioned in 1991. Wind Turbines can be defined as “man-made vertical structures” whose blades almost incessantly rotate, and as such often attract people’s attention.

This research paper is a prologue to describe the atmospheres of Venus, Earth and Mars along with their similarities and differences in terms of atmosphere. The purpose behind this research is to study the atmospheres of Venus and Mars which create their impacts on Earth’s atmosphere.

Surface water is the “precipitation falling on land areas and moving on the land surface as sheet flows or as stream flow” (Gupta, 2010 p.20). It is also the accumulation of water in low lying areas such as swamps and lakes.

The rice crisis in Nepali can be attributed to increasing environmental degradation as well as food insecurity in the area. Food security or insecurity is crucially related to the changing patterns of claims and power over food.

Disambiguation of engineering terminologies assists in clearly defining the different elements involved in engineering projects and activities. The guideline remains critical in offering people in other professions, an insight into the engineering profession.

Each type possesses a distinct, identifiable body protein coating, though having closely related rod shape and flagellated. Salmonella bacterium causes diseases globally primarily in people, animals and birds. The key maladies attributed with this bacterium encompass Typhoid Fever and Gastroenteritis, mainly evident in human beings (Porwollik 176).

Within twelve days after the earthquake, 52 aftershocks were felt that were also of significant magnitude. The earthquake caused massive destruction to Haiti, and especially to the capital. Most of the government buildings and other facilities were destroyed by the earthquake.

‘Melbourne 2030’ is the metropolitan planning policy developed by the state government in 2002, with the objective of steering future development to appropriate locations (Eccles & Bryant 2006, p.2). Subsequent to the adoption of ‘Melbourne 2030’, a succession of comprehensive follow-up plans for development are being implemented.

What Is The Position of Biofuels In Europe Currently? The requirement of biofuels has been witnessing an increase owing to its use with regard to the transport segment as a reaction to the issue of energy security as well as concerns regarding climate alterations.

Each industrial investment aims at achieving the optimal relationship between the production processes and the consumption process. In this regard, the main interest goes to the aspect of product sourcing in form of raw materials and the market where the product is going to be consumed.

The fact that the nature is violated and there are made many mistakes, directed on its destruction, cannot be beneficial for the humanity for sure. That is why there are a lot of controversies, which occur in the field of natural oil and gas extraction from the drilling of offshore lines.

The name often refers to a category name of metalloids (semimetals) and metals associated with eco-toxicity or toxicity potential and contamination (Daffus, 2002). There is an assumption that all heavy-metals and their compounds have properties that are eco-toxic or highly toxic.

The regulations for the transportation of hazardous materials are very comprehensive and are designed to govern all transportation activities which involve hazardous materials. The transport activities such as packaging, shipping, inspection, testing, forwarding and brokerage of hazardous materials are regulated by the provisions within the Hazardous Materials Regulations.

Deforestation of the Amazon is releasing millions of tons of carbon dioxide into the atmosphere, and it has been scientifically proved that to keep the Amazon protected from anything that would cause its current quality or condition to change or deteriorate or cause it to fall out of use will significantly stabilize greenhouse gas emissions (Sellers 1993).

For purposes of computing carbon footprint, it is pertinent to ensure that there are established boundaries of computation. This is because the computation of carbon footprint can be visualized as having a number of boundaries that are different.

This is so because the ocean is slow to warm up. However, most scientists are optimistic and proactive encouraging the world to take measures geared towards mitigating global warming caused by greenhouse gaseous emissions. Policy-makers have also taken action-oriented strategies towards achievement of this role.

Currently, vast research suggests that global warming is ever increasing due to the high concentration of green house gases within the atmosphere. The green house effect is experienced widely.

Today the process is done using algorithms and bioinformatics techniques to identify proteins that are present on the cell surface or released by the microorganism (that could provide an antigenic response). This process may take a few days to a few weeks.

Table of contents Abstract: This paper sets out to examine the causes of acid mine drainage of a site under investigation-a long-abandoned coal mine. The analyses of the samples collected were done to ascertain the alleged source of the river contamination.

The paper further explains the damages and the effects of the earthquake. The history of earthquakes in Japan can be explained with exceptional attention to some of the major earthquakes in Japan. The paper also discusses the special location of Japan that makes it vulnerable to earthquakes, volcanoes, and tsunamis.

Every year disasters and emergencies take their toll on lives, homes, businesses and industries. The program is to be originated from a practical real-world example that has been experienced before. In this case we have decided to use the last earthquakes In Japan and the Florida hurricane of 2005 as the basis for the training.

This paper recognizes that AMD is one of the environmental threats in the offing as most of the economies are hinged in the process of mining’s that contributes a huge chunk of income to the struggling economies of any states in the world.

The human population has exerted great pressure on local, national, regional, and global environment (Speth and Haas, 2007). Generally, this increasing population has been undertaking various activities, which have had impact on the physical environment. Observation made is that, as the number of people on the planet continues to grow and consumer aspirations of people continue to increase, the collective impact of human behaviours on the planet is becoming increasingly heavy and global in nature (Speth and Haas, 2007).

, taking into consideration of known and unexpected contingencies. So that it is the duty of the project manager to study about the environmental aspects of area before launching a project.

These result into the destruction of ecosystems and loss of species variation. The surrounding is considered degraded when habitats are subject to destruction, and the environmental resources are not enough to satisfy the organisms’ needs. Environmental destruction can be triggered by the natural and man’s activities.

Definitions vary from scientist to scientists and from research to research. However if these data come from a single body, they can be precise. National Health and Nutritional Examination Survey (NHANES) is one such undertaking of US Department of Health and Human Services.
