The Galapagos Island has a natural treasure of a distinct ecosystem because of various endemic species. As a result of the significant environmental and ecological characteristic of the Galapagos Island, it stimulates the development of sustainable ecotourism industry. Accounting to observe and collect the important information about the unique species which cannot find anywhere else on Earth, this inspiring Charles Darwin to form his famous theory of evolution by natural selection. However, similar with other isolated islands, the Galapagos Islands also face some serious challenges about their ecosystems for introduced species, fishing and human impacts. On the other hand, the development of ecotourism is beneficial to Galapagos residents …show more content…
Introduced plants and animals from the outside world are particularly devastating to the fragile ecosystems in the islands. The most destructive animal in the Galapagos Islands is goats which were introduced in the 1850s. It is an adaptable animal which can turn a low-lying island into a dessert in a short time and it is also hard to exterminate. Therefore, the only solution is using helicopters to locate them. After the eradication of goat, some animals like rats, donkeys and pigs threaten the ecosystem currently because rats eat eggs of giant tortoises, donkeys devour vegetation and pigs destroy bird nests. Except for animals, invasive plants in the Galapagos Islands also effect the ecosystem, such as, guava, elephant grass and quinine tree. Thus, the Galapagos inspection and Quarantine System was established in 2000 to control the introduction of new species. Moreover, the organizations in the islands start to focus on eliminating all introduced animal like cattle, goats and pigs, providing a neutering plans for feral dogs and cats on inhabited islands and getting rid of introduced rodents. “But eradicating introduced species and keeping new ones from arriving is a never-ending and enormously costly struggle.” The Galapagos Islands has a rich marine ecosystem, this supports all terrestrial life on the island. However, over-fishing and illegal industrial fishing by locals threaten to undermine the marine system. Sea cucumber and sharps become the main targets from other countries illegally enter the marine reserve to catch them because it is popular for aphrodisiac and medicinal qualities in Asian markets. Although the Galapagos National Park Service banned all fishing in the islands because of the increasingly decrease of sea cucumber and sharps, they still remain at an
In Charles Darwin’s life he had helped make a significant advancement in the way mankind viewed the world. With his observations, he played a part in shifting the model of evolution into his peers’ minds. Darwin’s theory on natural selection impacted the areas of science and religion because it questioned and challenged the Bible; and anything that challenged the Bible in Darwin’s era was sure to create contention with the church. Members of the Church took offense to Darwin’s Origins of Species because it unswervingly contradicted the teachings of the book of Genesis in the Bible. (Zhao, 2009) Natural selection changed the way people thought. Where the Bible teaches that “all organisms have been in an unchanging state since the great flood, and that everything twas molded in God’s will.” (Zhao, 2009) Darwin’s geological journey to the Galapagos Islands is where he was first able to get the observations he needed to prove how various species change over t...
Madagascar is one of the most diverse areas of land that has undergone evolution totally independent from surrounding continents. The plant and animal species located on the island are all endemic to the island, meaning all are native species. The amount of diversity is very high compared to that of other continents and the species found here cannot be found anywhere else in the world. Currently all organisms located on this island are in danger, even the humans. Much damage has already been done, yet each year the land seems to die even more. Many species are dying off rapidly and drastic measures will have to be taken to stop all of these species from becoming extinct.
In the article "Island Civilization: A vision for human occupancy of earth in the fourth millennium" a very good point was made about how humans are not treating the earth with respect, however our generation still has a chance to turn the earth from cancerous to healthy.
Once named the friendliest city in the world, Puerto Vallarta in my eyes continues to carry that reputation. The people who live there are what make this place so special; it is my most desired place to travel to. Puerto Vallarta, Mexico sits along the coast of Banderas Bay in the Pacific Ocean. Along with having exotic scenery, they are known for having an exceptional variety of food. With the dark frigid winter creeping up on us, my head wanders to memories of missed friends and 90 degree temperatures.
Did you know that you happen to be surrounded by invasive species? These species are animals that come into areas they do not belong in. The articles, “Invaders among Us,” and “Invader Alert,” show this. They harm the environment, cost tons of money in damage and extermination, and they have to be prevented.
This book claims to be about evolution, centered in the location made famous by Charles Darwin, the Galapagos Islands. I read this book on the recommendation of a good friend who knows I am interested in birds and thought I might get something out of it. Indeed, the few parts of the book actually about the Gouldian Finches of the Galapagos Islands are fascinating. The book records in detail some of the trials the Dr. Peter Grant family endured in studying these birds on a hot volcanic rock. However, the writers and editors of the book avoid simple logic and put a spin on history that is misleading. The facts and logic presented in The Beak of the Finch really make the book's author out to be a closet creationist.
Kurt Vonnegut's Galapagos was written one million years ahead of the year 1986 AD. In this book, Vonnegut argues that the ultimate effect of humanity's sociological problems with technology is that man's intelligence will be the downfall and destruction of the human race. The essential point made by Vonnegut in this work is that the "great big brains" of humanity drives people to go further into technology and create new weapons that will lead to the demolition of man kind; Vonnegut disagreed against virtually every technological development (made by “big brains”).
The Galapagos Islands, located about 600 miles west of continental Ecuador, contain a rich history of settlement and exploration and represent a living example of evolution that is still relevant today. For centuries, this chain of volcanic islands has been used uniquely by various cultures based off distinct needs. What has remained the same however is the fact that island isolation has forced many animal and plant species to adapt differently from one another based off their island’s environmental conditions, creating a living model of microevolution over time. Today, these models tend to be the primary resources used by biology professors when teaching their students evolutionary topics.
Their findings contributed to a further explanation of the definition of an invasive species. It was concluded that invasive species are detrimental to the environment that they are invading. Jackson (2015) mentioned that negative relationships among invaders are a particular concern since it is possible that both of the invasive species would need to be controlled in order for an area to rebound after invasion. Hoopes et al. (2013) concluded that native species on island refuges are more likely to be come extinct during an invasion compared to those of mainland refuges. These results also help to confirm the importance of understanding invasive species from a conservation point of view since invasive species are a major threat to native populations in their

Charles Darwin began his scientific breakthroughs and upcoming theories when he began an expedition trip to the Galapagos Islands of South America. While studying there, he discovered that each island had its own type of plant and animal species. Although these plants and animals were similar in appearance, they had other characteristics that made them differ from one another and seem to not appear as similar. Darwin questioned why these plants and animals were on these islands and why they are different in ways.
Invasive alien species are disrupting and changing the normal ecological functions of biomes, ecosystems, and the biosphere as a whole (CBD, 2009). They are a threat to biodiversity and can cause damage to, or even eradicate native species which natural cycles and other organisms depend on. While disrupting energy flow, food chains, and shaking the structure of ecosystems to the core, invasive species create not only ecological, but also a whole host of social, economical, and health issues that affect the livelihood of almost every organism on earth, including humans (CBD, 2009).
Many factors can cause endangerment such as climate, pollution, or not being able to adjust to an ecosystem. Yet, the major factor for our iguana was a biotic factor. An introduced species of goats, mongoose, domestic cats, and rats were moved onto their lands. Other minor factors were consumers, also known as producers, preying on the iguana. The only noticeable act of predation that is big enough to be recorded as a factor against the iguana is the species of Fiji Hawk, yet on occasions feral cats or mongoose will also prey on the Fiji Crested Iguana.

The Galapagos Island Tortoise or “Giant Tortoise” is a very interesting breed of reptile. They can live up to 1 year without drinking or eating anything because of their internal structure. The tortoise has been put on the endangered species list by the Ecuadorian government since there are less than 15,000 left on the islands. There are a lot of preservation attempts being used to save them, but wild animals and poachers are still threatening the species. Important things to know are what makes them such a special species, why people would hunt them, and what’s being done to save them.
Our first destination will not be in continental Ecuador rather the islands due west otherwise known as the Galapagos Islands. These islands are cut through the equator and cater to all sorts of living creature, including the well-known giant tortoises. The Galapagos have interesting residents including the unique marine lizard, the only that can swim in the ocean. There are also species that are not known to be in the extreme heat of the world like the Galapagos penguin. Around the island 400 plus fish species are known and snorkeling here is the best in the world, seeing these fish, sank ships, and maybe even a tor...
