The Galapagos Islands Essay Example for Free

The Galapagos Islands Essay The Galapagos Islands were first inscribed as a World Heritage site in danger in 1978. This was extended in 2001 and they were again inscribed in June 2007. The islands are found on the Pacific Ocean, 1000 kilometer from the South American continent, they are in Ecuador. They are 19 islands which lie on equator so their seasons vary very little. They have been called a unique â€Å"living museum and showcase of evolution†. (www. whc. unesco/org/en/danger). The islands were formed by seismic and volcanic activities which are still ongoing processes. These together with the extreme isolation of the islands, led to the development of unusual animal life such as the land iguana, giant tortoise and many types of finch. The finch inspired Darwin’s theory of evolution following his visit in 1835. The islands are referred to as an archipelago as they are very isolated from the nearest continent and the islands themselves are separated from one another. This separation and differences in climates favors evolutionary change. As a result, populations that are related follow separate evolution tracks leading to emergence of various species and even further diversification. The species so formed become very susceptible to changes in the environment. ( www. darwinfoundation. org) The uniqueness of the island lies in its marine and land ecosystems, and presence of flora and fauna endemic to the islands and in most cases found nowhere else in the world. The marine ecosystem is composed of both cold and warm water current systems, marine landscapes â€Å"bajos†- these are underwater mountains formed by volcanic activity they rise almost to the oceans surface. Some of the coastal animals found in the Galapagos marine reserve are sea lions, fur seals, albatrosses, several species of booby, frigate bird species, sea turtles marine iguana, penguins and flightless cormorants. (www. darwin. foundation. org) The land habitats of the Galapagos are mainly determined by their vegetation which is in turn determined by the local climate. The vegetation of the area is strongly zoned by altitude. The land ecosystem has such animal species as land iguanas, land snails, rice rats among others. The Galapagos contain a total of 560 native species of flora,180 are endemic (www. darwinfoundation. org). Some of the plant species include scalesia, opuntia cacti and the Galapagos rock-pursane and other lesser known species. Human intrusions threatening the area Threats to this hub of diversity are mainly in the form of fishing and tourism by humans. In the 1990s, fishing led to a big decline in some of the marine species such as sea-cucumbers and sharks. Then, the fishermen would fish the sharks just for their fins and the remainder of the shark’s body would go to waste. Fishing is the second most important economic activity in the region and marine resources were overused by such practices as illegal fishing and over fishing. The dangers presented by the Galapagos fisheries are-: i) Large international vessels fishing around the Galapagos pelagic zones and inside the Galapagos Marine Reserve (GMR) which is illegal. Long-lining and use of large seines are modern high-technology methods with devastating effects of depleting marine species. (www. darwinfoundation. org) ii) There has also been a rapid influx of poor fishermen from the mainland of Ecuador who serve the interests of mainland fishing companies and middlemen buyers. The fishermen are provided with capital in the form of a loan by the fishing companies to buy boats and equipment. The fishermen then sell the catch to the companies; the catch is later sold in the international market especially the Asian market. The influx has led to the human explosion being experienced in the islands and also the immigration brings with it invasive species which compete with the natural species of the islands decreasing their survival chances. ( www-darwinsfoundation. org) Tourism is the leading economic activity in the Galapagos Islands. Tourism has grown economically at 14% per year and this has lead to the Galapagos experiencing drastic, social, economic, cultural and ecological changes. (www. galapagos. org) The dangers that immigration poses include increased pollution, overuse of resources and eventually a charge in climate and introduction of invasive species. A change in climate will lead to loss of some of the species in the island. Invasive species refers to alien plants, diseases, insects and other organisms that people bring inadvertently to the islands. There are now 1,321 introduced species, compared to 112 identified in 1990. These include 748 species of introduced plants compared to 500 species of native plants and at least 490 species of introduced insects. The risk of the arrival of pathogens such as the West Nile virus, insect pests, and new predators is now high-: Dengue-carrying mosquitoes and some avian diseases are new arrivals in the islands. (www. galapagos. org,2007) Existing protection areas The Galapagos Islands have several protection areas. The Galapagos National Park (GNP) is one of this. 97% of the area covered by islands was designated as a national park in 1959. The lands not included were the settlement areas. Later in 1967, a park service Galapagos National Park service (GNPS) was set up to oversee management and administration of the park. The GNP is made up of 13 large islands, 17 small islands and 40 rocks. (www. galapagos. org/). The park authorities educate the visitors and enforce the laws and regulations of the park. The GNPS also oversees the management and administration of the Galapagos Marine Reserve (GMR) which was set up in 1998, another protection area. The GMR’s function is to protect the waters surrounding the archipelago. 3000 species of marine plant and animals are found in the GMR. The necessity of the GMR became apparent when in the 1990s fishing activities around the archipelago increased and almost had devastating effects on the marine species due to the high demand of both sea cucumbers and sharks’ fins. The GNPS also approves itineraries. This ensures that no one place is too frequently visited. This serves to distribute tourism to all the islands, decreasing chances of harm to the environment. The GNPS works together with the Charles Darwin Foundation, now known as the Galapagos Conservancy. The foundation provides the scientific and technical know-how required in maintenance of the natural biodiversity and ecosystems of the islands. Other protected areas include Sangay National Park, Limoncocha Reserve, and Antisana Ecological Reserve which has the Antisana volcano that is 5758 meters high. The reserve was created in 1993. The Cuxabeno Forest Reserve is another protected area, for two thirds of the year the forest is submerged in water and when it is not, it is made up of dry futbol fields (www. ecuador. com/,2007). It was established in 1979. Part of the 6000 square Kilometer rain forest makes up part of the Amazon Rain forest. There are indigenous people found in this forest whose contribution to reservation is through jungle tours and eco-tourism. Existing efforts in Galapagos to protect and preserve the area include:- i) Registration of fishermen to fishermen’s cooperatives. This has enabled the monitoring of fishermen’s activities and from this an estimate of how much fishing is going on can be got. Also, it makes it easier to track illegal fishing. ii) Establishment of the Galapagos Marine Reserve in March 1998. In this area, all fishing is banned. The area covered by the GMR was expanded TO cover 40 miles around the whole archipelago. These are also zones of protection around the islands. All these are patrolled by GNPs park rangers. The sea shepherd conservation society assists with carrying out patrols in the service. iii) Approving the designation of the Galapagos Archipelago as Particularly Sensitive Sea Area (PSSA) by the Marine Environment Protection Committee(MEPC). PSSA is defined by the International Marine Organization (IMO) as â€Å"an area that needs special protection through action by IMO because of its significance for recognized ecological socio economic or scientific reasons and because it may be vulnerable to damage by international shipping activities†. ([IMO,2001]www. dorwinfoundation. org) iv) Introduction of residence controls which decrease immigration and in turn lower the flow of alien species. The aim is to curb population growth. The controls are however difficult to implement because it is difficult to determine genuine residents and those who come and go but have permanent residence elsewhere. (www. law. emory. edu/ ) v) Education of residents, tourists and Galapagos policy makers on how beneficial sound conservation, practices, polity and sustainable economic activities are for example finding alternative viable economic activities for the local fishermen. vi) The success of Project Isabela. This project has seen a large area being freed of feral goats and pigs. Subsequently there has been an increase in Galapagos’s rails. Areas that had been previously degraded have now become resting areas for petrels and re-establishment of vegetation like tree-terns and endemic scalesia has occurred. Also native invertebrates thought to be extinct are now being identified (www. darwinfoundation. org, 2007) vii) Successful breeding programs for tortoise run by the Charles Darwin Foundation and GPNS has led to repopulation of some islands with their native reptile species. The giant tortoise was becoming extinct due to hunting by humans and other animals. (www. galapagos. org) viii) Inclusion of various sectors in the management board of the Galapagos National Park service has been instrumental in bringing about an attitude of conservation and preservation. At first the local people felt that the government was only concerned about plant and animal life. The multisectoral approach involves key players in fishing, tourism and conservation sectors and also the local person. (www. galapagos. online/) Including the local people has helped to enhance the concept of conversation because the local people no longer feel neglected. Should human intrusion go unchecked, the loss will be great. Maintenance of the rich biodiversity of the islands is achievable of the ecosystem can support sustainable economic use where the local people, conservationist and players in tourism and fishing industry feel their needs have been put into consideration. An example of how the biodiversity can lost is seen in the fact that the present tortoise population is very small. Poaching, destruction of habitats and the presence of invasive species are the main dangers to the tortoise population. (www. galapagos. org, 2007). Though the near extinction of the giant tortoise caught the attention of people and the process was reversed the giant tortoise is not out of the woods yet, and the work of repatriation needs support. In the process of poaching the tortoise, various invasive species which trampled on the tortoise’s habitat were limited and multiplied faster than the tortoise would, leading to destruction of the tortoise habit. The mangrove finch is another species being driven towards extinction. Again the greatest threat to be mangrove forests and the finches is the exploding human presence in the Galapagos. (http://www. galapagos. org/about. html). Increased activity among humans increases the risk of disease further especially avian pox, black rats, cats, fire ants the parasitic fly philornis. All threaten the mangrove finch as well as vulnerable species in Galapagos (http://www. galapagos. org/about. html. ) For the mangrove finch to be saved there has to be study of the mangrove finch and its habitat. Activities that would require support in the mangrove finch conservation project include: ? Creating potential captive breeding facilities for the mangrove finch. ? Resting degraded mangrove finch ecosystem, including establishment of new mangrove forest plots. ? Releasing the captive-bred birds to sites on Isabela and Fernandina islands where the mangrove finch once thrived. For the future generations to be able to see and be part of the abundant biodiversity in the Galapagos islands the necessary funds and a coalition of leadership are needed to successfully conserve and preserve the world heritage site. Otherwise, we risk losing not just an area rich in natural biodiversity but a site of origin of human philosophy and in the process part of the human race. Because of ecological interdependence, there can be no climate changes that will affect animals and plants only, whatever adverse effects will affect flora and fauna will also affect the human race. This means that no part of the ecosystem will be spared the price of not doing all that is necessary to protect and preserve the balance of nature. Conclusion Islands are generally smaller than continental areas but are basically more or less the same with similar social, economic and ecologic changes happening. This then means that islands can and should serve as a model to the rest of the world for these changes (www. darwinsoundation. org). In coming up with solutions to the Galapagos problems we are more or less coming up with a prototype to solve problems that will occur in other continents of the world, but if we cannot resolve the issues then it means that we will also fail in achieving a society where there is a balance of nature and social economic sustainability in the rest of the world.

Cesar Chavez Essays -- Civil Rights, Labor, Chavez, farm workers

One of the greatest civil rights activists of our time; one who believed the ways of Gandhi and Martin Luther King that â€Å"violence can only hurt us and our cause† (Cesar Chavez); a quiet, devoted, small catholic man who had nothing just like those he help fight for; â€Å"one of America's most influential labor leaders of the late twentieth century† (Griswold del Castillo); and one â€Å"who became the most important Mexican-American leader in the history of the United States† (Ender). Cesar Chavez; an American farm worker, who would soon become the labor leader that led to numerous improvements for union workers; it is recorded that Chavez was born near Yuma, Arizona on March 31, 1927 and died on April 23, 1993 in San Luis, Arizona. (Wikipedia) His life affected many others as his unselfish deeds changed the labor union force forever. This essay will discuss the reasons Cesar Chavez became involved in Union rights, the immediate impact he had, and also the legacy he left behind with his actions that influenced American society. There are many reasons why Chavez became part of the movement, but the major reason was his childhood. It is noted that Cesar Chavez was one of five children born to Librado Chavez and Juana Estrada who were farmers. As a child in Arizona, he grew up nourished by the values of his family and his rural Mexican-American community. His mother taught him the importance of non-violence and self-sacrifice and his grandmother impressed upon his the values of the Catholic faith. And as a child, he experienced racial discrimination in school. (Griswold del Castillo) Chavez quit school after the eighth grade to work full-time in the fields. His grandfather had homesteaded some 112 acres that the family soon lost because of t... ... Richard. "Cesar Estrada Chavez."The Scribner Encyclopedia of American Lives, Vol 3: 1991-1993.

Vacant Chapter 14 Home

â€Å"Margie's been coming by every night to make sure I have food or whatever. We would talk for a little while.† Emily stops and looks toward the door. â€Å"I'm guessing she hasn't shown up tonight because she saw the car out front.† I yawn, but not because I'm bored. I could listen to Emily talk forever about the six days I missed out on. I'm exhausted though and the days I went without restful sleep are showing. â€Å"You are so tired, Ethan. We can do this tomorrow.† Her hand slides down my face as a warm smile takes over her features. I stand to head toward the bedroom, and she turns to make her bed on the couch. â€Å"Emily?† I question her. â€Å"I was hoping we could go to bed.† The, â€Å"well, duh,† look she gives me, and then returns to making her bed tells me she's not understanding my meaning. â€Å"No, ummm†¦Ã¢â‚¬  Why am I so nervous to say this? I roll my eyes at myself. â€Å"Like, together,† I say as I step to the doorway of the bedroom, â€Å"in here.† Her eyes get huge, owl huge, and I realize my mistake. â€Å"No! Not like that. I just†¦.† I have messed up so much; I want to get something right, so I pause and collect my thoughts. â€Å"No more sleeping on the couch, Emily. We're adults who love each other. I don't want to be apart anymore. Come to bed with me and sleep. Nothing else.† I want her to understand that I'm not pushing. I want her close, but I don't want her to be uncomfortable. This is a monumental step forward for us. â€Å"You, me, pajamas, and sleeping†¦Ã¢â‚¬  I decide that perhaps a little lighthearted humor won't hurt. â€Å"And maybe a little more of the kissing.† I will behave. I put on full length pajama pants – over my boxers – and t-shirt. I get under the sheet, lie flat on my back and cross my hands over my stomach. I wait. Patiently? No. Emily enters the bedroom from the bathroom, and I can tell she's nervous. I'm not sure if her anxiety is because of the prospect of sleeping with me or that she is wearing a tank and panty set I'm pretty sure was intended for a toddler and not a full grown woman. I can see her nipples. And her†¦I'm definitely in trouble. Do I tell her? I have no idea what the protocol is for divulging sexual history to a prospective mate. Mate? I roll my eyes at myself again as images of Emily and me wrapped in fur coverings shoot through my mind. I'm running around with a spear shouting, â€Å"Me man, you woman.† It's totally ridiculous that I've reverted to a prehistoric mindset. If I were a caveman, I'd have an easier time with the subject at hand. I'd just grab Emily and shove my penis in her vagina with nothing more than grunts. Being without conversational language skills has its advantages; there's no way to explain everything. My thoughts have veered off course, and I need to focus on the woman crawling up the bed like a cat hunting a mouse. Even though I haven't admitted it to myself, this is one of the reasons I'm so afraid of this thing with Emily. Sex and the topic of sex have always been off the table with her. We have never discussed previous experiences. I'd always assumed Emily was a virgin, but maybe it was just wishful thinking on my part since she came to me at a young age. I'm not naive enough to think that teenage girls aren't having sex. I just didn't want Emily to be one of them. Being nervous about Emily's sexual experience, or lack thereof, isn't my only reason for pause. I don't know whether or not I should divulge my history. Part of me thinks it plays a huge part in things, while the other part of me says it doesn't matter. I'm torn and don't know which is right. I know honesty is the best policy, but will it do more harm than good in this case? â€Å"Ethan?† I look up and see those expressive eyes. She needs my comfort and acceptance. Even though I made it clear we are only sleeping tonight, it seems like she is still trying to persuade me to do more. How else would you explain the tiny underwear and feline-like movements? If I don't stop this dead in its tracks now, I know I won't. Things will go too far too fast. I open my arms in invitation, hoping she gets the message without hurt feelings. â€Å"Just lay down with me.† Why is she giggling? The haze from sleep is slowly lifting, and the morning sun shines through the window. I want to recap the events of last night before I open my eyes and look at the most important person in my life. â€Å"Ethan?† Emily whispers. â€Å"Hmmm,† I answer to let her know I'm awake. Her hand is on my stomach, under my shirt, where she strokes the hair just above my belly button. â€Å"Can I touch it?† Emily breathes in a hushed tone. My eyebrows furrow with my eyes still closed. â€Å"Touch what?† Another giggle. Emily's hand slides down a little further, and a finger dips inside the waist of my pajamas. Whoa! I grab her wrist to still her movement, but she tugs away. â€Å"I want this, Ethan. I want this with you. Please don't make me beg you.† The last thing I want is for Emily to connect negative feelings to sex with me, but I never came to a resolution last night. I am not sure how much to tell her, but I don't think dwelling on it any longer will help me decide. I'm going to have to throw a bone and see her response. â€Å"We need to talk, Emily.† â€Å"Later.† It's a bold statement on her part, but I can't deny her as her hand moves under my waistband. I'm ashamed to say that I've denied her touch for too long, and I don't want to wait for another second. Her lips move to mine, my mouth automatically opening. I want nothing more than to swallow her whole but settle for the caress of her tongue on mine. Her fingers play under my pants, flirting with the idea of moving lower. My hands have been flat against the mattress until now, but I can't stop their journey to her arms, then back. Knowing she is touching me intimately gives me the courage to do the same. My hand floats to the crest of her ass, gliding across her flesh. She moans, giving me the courage to extend my caress to her bare flesh beneath her panties. My touch is tentative because I want to get this right. â€Å"Yes,† comes her strangled plea. We continue kissing with nips and tugs of lips and teeth; my hand moves to the top of her thigh, then down to the dip where her ass meets her legs. She pushes toward me, her pussy opening to meet my waiting hand. I don't have to search far before encountering slick skin, eager for my attention. Her breath stutters as my fingers begin to move, stroking her. Her hand moves to touch me, her thumb rubbing my head, spreading the pre-cum. Her touch feels so good that I move my mouth away from hers, fearful I'll bite her. Instead, my teeth graze her jaw then continue to move lower. My mouth waters at the thought of tasting more of her. I've imagined what her nipples look like – taste like. I want to know that my fantasies don't compare, even a small portion, to the reality. But this is not a fantasy. This is someone I care about, dream about, someone who matters and this has to be right. I pull her tank down, exposing her breasts. My mouth immediately latches on, suckling and lapping at the darkened peak. My fingers massage while my tongue caresses, and in only a few seconds, Emily is panting and writhing. Her head falls to my chest as she stiffens in my arms. I've never felt so satisfied, despite not having my own release. But it doesn't matter, because I know that this is only the beginning. This is the first of many gifts I hope to give her. After I make her get dressed completely, we sit at the kitchen table for a much needed discussion. â€Å"So, you've never†¦.?† I start. â€Å"No.† While I'm deliriously happy Emily is a virgin, I also know the pain associated with the first time for a woman, and I'm not looking forward to inflicting that. I want to give her pleasure, not pain. â€Å"What about you?† Emily asks followed by a big gush of air. â€Å"Never mind; that's a stupid question. Of course you have. I mean, look at you.† I open my mouth to answer her, but she doesn't let me. â€Å"No, tell me. I want to know. How many?† And there lies the crux of my problem. I'm afraid to tell her, because if she knows, will she still trust me with her most precious gift?
