Download file to see previous pages Between 1900 and 2000 the world’s population increased by six billion and industrialization was at its peak (Wright & Boorse, 2010). Vast piece of land has been cleared to accommodate settlement and agriculture. All this contributed to 90% decline in ground water.
The trend of environmental degradation came to limelight in 1962 when Rachael Carson wrote a book called silent spring. Later, in 1972 report named limit to growth and another known as our common future in 1987 by Brundtland commission were published (Wright & Boorse, 2010). It was due to these three major publications that influenced the adoption of the ideology knows as sustainable development.
For clear evidence of the previous state of the environment, it was mandatory I review map and analyze them. The satellite vegetation maps showing the vegetation cover from 1800 to date and human settlements map over the same duration of time was a fundamental source of data for this study. Further, geological data on the trend of ground water was also influential in this study. Therefore, the major method of date collection was map reading and analysis.
In 1900 through to 2000, the world population has increased by six billion. Because of the high population increase, there was the need to find means to fend for the need of this large number, which led to clearing of forest by 90% to create space for settlement and cultivation. It was also during this time that the European countries and America engaged in high industrial activities, which tremendously impacted on the environment. Forest cover, which plays a role in enhancing hydrological cycle had reduced, meaning that rain had also reduced (Wright & Boorse, 2010). In this line, the amount of water that percolated through the soil profile to recharge the ground water was reduced by half. Since the developments of environmental policies, there have been attempts to reverse the damage that happened in 1900. In this pursuit, forest ...Download file to see next pagesRead More

... be independent and self-sufficiently resilient. However, it is impossible. “If they arise from the two masses themselves, they must be equal in magnitude but opposite in direction so that no net force arises from purely internal forces” (Newton, 2009). Pulling oneself up by one’s bootstraps involves only internal forces. REFERENCE Hewitt, P (2010). Physical Science Explorations. New York: Pearson. Newton’s Second Law (2009). Newton’s Laws (2009).

...Environmental Science Lab Starbuck is the global leader in coffee retailing. The company has thousands of coffee shops distributed all over the world. Most of the coffee shops are located in U.S and U.K. For every cup of coffee sold by Starbucks, there are underlying costs to the environment. It is therefore important to make an evaluation of the processes and materials used to get the coffee on the table with an aim of determining with certainty the amount of environmental impact of these coffee shops. Most of the coffee cups sold by Starbuck coffee outlets all over the world including Denver Colorado are made of paperboard. The constituent materials include trees, ink, plastics. The process of making...

... Transportation My main mode of transportation is road. I live in Denver, Colorado, and on a daily basis I usually drive my car to all my destinations. I find road transportation, and particularly driving my car to be remarkably convenient as compared to other modes of transportation. Driving my car is cheap, fast and efficient. I do not have to queue, pay and board a public plane or ship in order for me to reach my destination (Reggiani & Schintler 311). The above can be very stressful I prefer driving my own car, and as a result, I maintain my privacy and peace of mind. Driving my car has made it possible for me to keep my appointments since I usually arrive at my destinations on time. It is easy to travel by road because I... Transportation...

...Food and environment In the last two days, I have taken breakfast at home, which included a glass of milk and some cereals. I took mango juice from the canteen at tea break on the first day, and a piece of cake on the second day. I skipped lunch on the two days but enjoyed a cup of white tea at 4 pm. Dinners were rather early and since I love red meat, I cooked it with rice and kept the left over in the fridge, which I consumed on the second day. The eating habits I have adopted have both positive and negative effects on the environment. First, eating animal products such as meat and milk increases carbon emissions in the environment. This is because of production of commercial livestock, and processing of the same, which consumes...

...What I learned from Sustainable Designs Certainly, the greatest challenge today is to design buildings that meet the needs of the present without compromising the ability of future generations to meet their own needs. A good balance between social, economic and environment objectives is indeed a solution to this problem. Sustainable buildings are free from toxins and have clean air. I learned that recycling materials from old buildings and renovation is the best environment choice. At Alliance Centre, a complete change was needed to accommodate sustainable environment. First, incandescent lights saw replacement with by CFLs, water conservation fixtures replaced outdated technology, interface recycled-content carpeting was used... I learned...

...Reflection over Journal Experience I must admit that the journal experience was the best thing that ever happened in my academic life. I have been able to learn many things in a broader perspective than I did when I joined the course. All the journal experiences have had a tremendous impact in my way of thinking about health, economics, and most importantly, the environment. The journal experiences have enabled me to reflect on myself as an important element of the global ecosystem. I have come to understand that my behavior while dealing with resources directly or indirectly affects the existence of other forms of life. For instance, the journal experience on good use and recycling of materials has influenced the way I utilize... over...

...Science Lab 2 Science Lab 2 Introduction Speciation is the natural change in a species’ behavior and prevalence over a given periodfollowing a natural disturbance. This disturbance often cause of the species to locate to a different natural setting forcibly and almost immediately. In effect, the species is compelled to adapt and change to fit these new natural surroundings. The following lab report methodically accounts for the series of events following the sudden split of a species of lizards into two groups by a hurricane resulting in the isolation of a small group of individuals on an island far from the mainland. Hypothesis/Predicted Outcome Ecological conditions result in the natural selection of coloration in visits while... Lab 2...

...Science Lab Report   Sources of CO2 Emissions Carbon (IV) oxide emissions can occur due to both natural and human activities. Respiration, decomposition of fossils and oceanic release are among the natural sources of CO2 into the atmosphere. Natural sinks however provide balance to the amount of CO2 from these sources. However, human activities such as burning of fossil fuels, deforestation and cement production are just among the activities that have led to an imbalance in CO2 atmospheric concentration. This has been the case since the Industrial Revolution. This report is a study on the expected levels of CO2 emissions over the next years following a study on its levels over the past forty...
