Orca whales, also known as killer whales, should not be kept in captivity. Since 1961, hundreds of orca whales have been taken from their natural habitat and placed into captivity at aquariums and aquatic parks around the world for the sake of public displays, theatrical shows, and business profit. To date, more than 127 captured orcas have died (Whale and Dolphin Conservation, n.d., figure 3). The capturing and confinement of orca whales is clearly unethical and inhumane. It poses a…

Gandhi and his men set out on there religious retreat, Gandhi and several of his men went on a trail that took over 240 miles to the costal town of Dandi. Furthermore, Gandhi and his supporters were to disobey the British policy by making salt from seawater. Along the way Gandhi addressed large crowds, and with each passing day an increasing number of people joined the salt satyagraha, or the “truth force.” Gandhi increasingly demanded “swaraj”, or self rule. Swaraj basically meant Indian…

Based on the readings and your own research, answer the following questions: 1. How do pathogenic organisms get into a water source? Human and animal wastes (feces) are major source for pathogenic organisms (such as bacteria, viruses, and protozoa) into a water source (surface or groundwater). As water (surface runoff) resulting from the storm or precipitation or snowmelt runs over the land surface, it will pick up potential pollutants include pathogenic organisms as it runs over livestock…

intuitive, and my German is still sharp. I just have to get it out over the nearby water and scuttle it in the Baltic Sea. I will be a one-way trip unless I can swim ashore, but I’m not counting on miracles. The aircraft is sinking, and the cold seawater is making my arms and legs numb. My breathing is getting more labored. The "flying saucer" is trying to get revenge, sucking me down into it and my legs refuse to kick. I feel myself sinking. “Grab him,” an old man yells in Swedish. “Quick…

springs could be found in many countries (NG.org). Around 500 B.C. the Chinese invented a way to use this mysterious fire (NG.org). They built a crude pipeline out of bamboo shoots (NG.org). This transported the gas to where they could use it to boil seawater (NG.org). This separated the salt from the water and the water became drinkable (NG.org). Around 1785, the first country to commercialize natural gas was Great Britten. The English produces natural gas from coal. They used the gas to light…

Many solutions have come to the table, including a desalination Desalination is extracting the salt from seawater. Desalination is not a new idea and is already used in many regions, particularly in the Middle East. Saudi Arabia alone accounts for about a tenth of global desalination. Israel uses desalination technology to provide about a fourth of its domestic…

this has meant a natural rise in the levels of CO2 in the oceans. This rise can have a large effect on the natural biogeochemical cycles of the oceans. The largest effect will be seen through the acidification of the oceans. When CO2 is dissolved in seawater it increases the concentration of hydrogen ions in the ocean, which then decreases the overall pH, causing acidification. This acidification can have a detrimental effect on marine biota through two main mechanisms: hypercapnia and the…

From food containers to cars and from toys to technology, everything can be made out of plastic. Plastics are carbon based polymers (polymers mean something of many parts) mostly made from petroleum. There are approximately 100 million tons of plastic produced every year. Some people believed that we have entered the age…

continent sits on the oceanic crust, which explains the tectonic plate movement throughout the crust. The Appalachian region is a plate margin and has periodically submerged beneath shallow seas (Galey, 1948). Upwelling is the definition of a rise in seawater. Plate margins are the layers covering the earth’s surface. Some examples of margins include mountains, folds, ridges and faults. Tectonic activity in the Appalachian Basin occurred when the plate submerged within a convection process. A…

“They were piercingly blue eyes, not icy blue, but more like the seawater.” (40). Only within one line, the words used and how effective her use of hyperbole creates images for the readers to visualize. The words such as piercingly or icy create an exaggerated feeling. Another clear evidence is when Carpenter writes “The…
