Key Developments within the Global Airline Industry Essay

Key Developments within the Global Airline Industry - Essay Example The researcher states that the growth of the airline industry is averaged at 5 percent annually through the estimates have changed due to changing economic conditions and differences in air travel safety across continents. According to the International Air Transport Association (IATA), the industry experienced a $ 4 billion decline in profitability in 2011. Surprisingly, analysts point that global air travel passengers will hit a mark of 3.5 billion passengers annually in2015 which is a 30 percent increase from the current figures. IATA clarifies that increase in global fuel costs will impact negatively on the profitability of many airlines since it is estimated that global airlines will experience about $ 1.6 billion fuel cost increases. Accordingly, fuel costs account for about 35 percent of airline costs currently, up from 15 percent in 2000. Numerous uncertainties such as the recent global financial crisis and global terrorism have negatively affected the profitability of the in dustry. The developments have led to shifts in t global air travel services provision as major global players have intensified competition in the new centers of production. Additionally, the emergence of new international financial hubs such as China has led to movements of major airlines from their home markets to new high growth markets. Transnational corporations like the World Trade Bank and International Monetary Fund have facilitated globalization through the elimination of barriers in trade and investment flows among the nations. There are numerous factors affect the competitiveness of the airline in the domestic market. Some factors include the level of technological innovation, the influencing factor creation, and organization of the airline. According to Porter’s diamond model, the structure of the industry, the rivalry of the firms, the factor conditions, demand in the market and supportive industries are the important internal factors that determine the success of the firm in the domestic or national market.

Pollution and Lake Erie Term Paper Example | Topics and Well Written Essays - 1000 words

Pollution and Lake Erie - Term Paper Example With increase in population a lot of things changed for this lake. This increase gave rise to pollution in the form of human waste, sawdust, agriculture chaff, oil etc. The forests around this lake were cut down in order to get wood for construction purposes. Around 1960s the whole outlook of the lake changed due to this pollution caused mainly by industrial waste and untreated sewage. Rivers that flowed into this lake were also much polluted. This problem became so serious that warnings were given to the residents against the contact with the water. All of this made life in this water impossible; hence, this lake was declared ‘dead’. Lake Erie is considered dead, as a consequence of eutrophication (Gilpin 1995). Lake Erie is one of the lakes in the world which has a very large dead zone. The area which lacks oxygen is called a dead zone. According to scientific researches done by scientists dead zone works in two distinct layers. There are two separate layers of water i n the lake; one is on the top and the other at the bottom. Temperatures in these two layers are mostly different except in the springtime where the temperature in both layers is the same. In summers, the water in the upper layer warms up and the bottom layer remains the same. This results in a significantly colder layer of water at the bottom of the lake. This difference in temperature between two layers is called thermocline. All the activities in the water takes place in the upper layer as all the sunlight and nutrients are present here. When the algae and animals present in the upper body die, they fall at the bottom and decomposition takes place. The process of decomposition uses up all the oxygen in these areas, hence, giving rise to dead zones. This problem is really bad in Lake Erie because the water here is not very deep and there is less oxygen in it so the oxygen is depleted very quickly. Scientists are making efforts to reduce this problem of oxygen depletion in Lake Erie . There are a lot of nutrients present in this lake and the sources of these nutrients are divided into two categories. These categories are called point sources and non point sources. Point sources are the sources through which the nutrients that are released into the water can be measured like wastewater treatment plants. On the other hand non point sources are the ones which cannot be measured for example agricultural runoff and the amount of fertilizers cannot be calculated accurately. It is still not possible to completely evaluate whether the dead zone is expanding or is recovering. It varies from year to year, according to the temperature. The great lakes national program office of USEPA is playing a vital role in repairing the Lake Erie. Surveys are conducted annually by these people to check the level, degree and occurrence of oxygen depletion in the lake basin. They also track the trend in which this occurs. These also check the phosphorus level in the water so that it doe s not exceed its level. Phosphorus changes water chemistry and can lead to changes in water oxygen levels that eventually impact aquatic plants and animals that feed off them (Davies & Mazurek 1998). The information gathered cannot be same for every year as weather is variable that changes every year so the level of oxygen and phosphorus varies each year. To do all this data is collected and EPA research is used. Side by side biological and geological surveys are also taken into consideration.
