Antarctic Impact
Human Effects on Antarctica
There are many unintended consequences of human activities that have had adverse effects on Antarctica. Global warming, which is all but certainly fueled at least in part by the human use of fossil fuels and the release of carbon and other molecules into the Earth's atmosphere, has had an impact on Antarctica despite the frozen continent's distance from anything resembling true modern industry (Ward 2001). The ice shelves surrounding the continent, which provide living habitats and feeding grounds for many land- and sea-dwelling Antarctic animals, have been melting and disintegrating at an increasing rate (Ward 2001). More direct impacts can be found resulting from commercial human activities, such as the harvesting of krill; though over-harvesting may be a problem in and of itself, this harvest also has the unintended consequence of limiting the food supply of...
On the one hand, greater knowledge about the impact of human activities generally and in the Antarctic specifically have led to modifications in behaviors that could reduce some of the impact had on the region, and helping to restore certain animal populations (Ward 2011). At the same time, the ever-increasing pace of human industry demands the ever-greater consumption of fuel and resources, and even newer technologies demand such resource use (Landcare Research 2001). All of this makes the existing problems in the Antarctic that much worse, as global warming and commercial harvesting continue.
If the scientific method were properly applied to the problems that Antarctic…

The plan would be the result of the scientific method, through which the impacts and causes of the current environmental problems would be addressed. Additionally, the scientific method would sit at the basis of the future actions to be taken. These would traditionally include: The search for alternative sources of energy The search for renewable sources of energy The creation of an infrastructure which allowed the propagation and populous use of alternative energies The
International Regulation of Tourism in Antarctica Since the mid-1980s, Antarctica has been an increasingly popular tourist destination, despite the relative danger of visiting the largest, least explored -- and arguably least understood -- continent on earth. Beginning with the 1959 treaty establishing Antarctica as an international zone free of claims of sovereignty by nation's that had been instrumental in establishing research stations there, there has been almost constant negotiation about how
Environmental Biology: The Effects of Pollution in the Ocean The oceans are being contaminated by pollution caused by oil spills, tanker discharges, untreated municipal wastes and agrochemical residues. Pollution is known to have destabilized many coastal ecosystems and is believed to be responsible for the decline in phytoplankton and consumable shellfish which usually thrive further out to sea. Medical wastes, beach visitors' garbage, waterfront businesses account for most of the toxic
Women's Biology Review and critique of a current article relating to women's biology How Emergency Contraception Works to Prevent Pregnancy Emergency contraceptives are drugs used to prevent pregnancy after women indulges in unprotected sex. There is a slight difference between birth control methods and use of contraceptives in preventing unplanned pregnancy. It is significant for women and men to learn and choose the appropriate method that guarantees their well-being. Use of contraceptives prevent
(Jordans, 2008) "Europe's unilateral approach will only lead to legal battles and trade wars," Bisignani also stressed. (Jordans, 2008) a hint of this contention occurring in the future was evidenced recently when 27 nations, including the U.S., China and 25 other countries, registered opposition to the EU's attempt to include commercial airlines in its cap-and-trade program by supporting an ICAO-run program. This signal confirmed united opposition to the European
