The huge salaries of some top athletes from an economic perspective - Essay Example The paper tells that in the opinions of many researchers and media personalities, the salaries of athletes are too high. However, judging from a series of empirical studies and economic theory arguments, the opposite of this notion is true. Few players earn extremely high wages, most likely due to the innate characteristics of the sport labour markets both on the production and on demand sides. Through the introduction of broadcasting channels in the second half of the 20th century, the salaries of players have substantially grown, as people have exhibited exceeding interest in the need to watch sports as a preferable entertainment mode. Looking into the wages of the highest earning players, boxing produced the top two earners. Floyd Mayweather and Manny Pacquiao top the list with the latter earning $160million, $140 less than that earned by the former. Soccer had the third and four largest earners Cristiano Ronaldo and Lionel Messi, who pocket $79.6million and $73.8million respectiv ely. Roger Federer and Lebron James become the highest paid tennis and basketball players, earning $67 million and $64.8million respectively. The demand for labour in the sport market is a derived demand, which depends on the final product’s demand produced by the labour. The rigid supply of sport stars explains why the wages of professional sport stars is relatively high. The quality of demand and production of professional sport stars is not dependent on the increasing or decreasing numbers of consumers, though the market has a structure that can prevent practices such as free riding.

Ecologies and Environments United States - Essay Example According to ecologists’ studies, the Rocky Mountains, despite having a snow cover, do have diverse biotic zones that start from tops and extend to the lowlands and plains (U.S. Census Bureau, 2012). The biotic zones usually serve as essential habitats for numerous animals and plants, for instance, Tundra in Rocky Mountains of Colorado. The wildlife available in the Rocky Mountains encompasses elk, mule, pronghorns, black bears, coyotes and grizzly bears. In addition, owing to the fact the U.S. seashores at both the Atlantic and Pacific oceans, the near states usually experience varying climate patterns compared to those of the interior regions (EPA, 2012). In addition, U.S like other industrial states has also experienced the increased predicament of obnoxious gas emissions from its chemical industries. However, as compared to the previous years the emissions have decreased because of the awareness the environmental authorities have created among the citizens to deal with the problem of global warming. For instance, the carbon monoxide emissions dropped from 114,465 in 2000 to 77,685 in 2008 despite minor fluctuations witnessed in between the years (U.S. Census Bureau, 2012). The forest cover occupies approximately one third of the total U.S.’ land; it provides habitats for numerous wild animals, not to mention other organisms. Forests have also benefited the society through the provision of clean water, reaction sites (camping and touring) and absorbing excess CO2, especially that generated by different industries (Rahm, 2010). Presently, the U.S. is experiencing habitat range rifts where numerous species are relocating to the Northern colder latitudes, for example, boreal forests, which are almost replacing Tundra vegetation. (Christiansen, Markstrom & Hay, 2011). This has led to negative impacts on numerous species’ habitats and wildlife that rely solely on Tundra ecosystem like snowy owl, for example. The reason can be found in the fact that temperatures are constantly increasing, especially in the central regions, which have yielded to the extinction of some animal species like American Pika etc (U.S. Census Bureau, 2012). List the specific factors that distinguish your local ecology and environment. 1. Range shifts - species are relocating to the Northern colder regions due to global warming and unpredictable climatic conditions. 2. Food web interruption due to the increasing rate of range shifts. 3. Precipitation, which has led to the increasing of the oceans’ water levels. 4. Forest cover, though it occupies the third of the U.S total land. 5. Rocky Mountains characterized by diverse biotic zones. Discuss how human activities have affected your local ecosystems Mining in US has become a serious threat to both the ecosystem and human life despite diverse state’s environmental agencies implementing strict rules and regulations to control it (Withington, 2012). The main threat lies in the release of obnoxious gases straight into the atmosphere and discharging of heavy metals into the water masses, which affects aquatic life (UGCRP, 2009). These heavy metals include cyanide, lead and mercury, which not only affect aquatic
