The Pros And Cons Of Ocean Exploration

No one can deny there are hardships people face when exploring new lands and creating governments far from home. European exploration was no exception. Though there were costs and benefits to European exploration, it is apparent through analysis of primary sources that the benefits outweighed the costs. Through the money made by trading and farming, the spread of Christianity to Indians, and the political power gained by conquering land, there were overwhelming benefits on the Spanish side.

In the world's oceans there a 5 large gyres. Each one of these gyres are known to be filled with trash. These gyres are, Indian Ocean Gyre , North Atlantic Gyre, North Pacific Gyre,South Atlantic Gyre, and South Pacific Gyre. The largest and most known gyre is found in the pacific ocean, and is known as the great pacific garbage patch. This garbage patch is double the size of Texas and can be as deep as nine feet in some areas. In 1971 it was suspected that only .1% of the world's trash went into the oceans. The projections today are far worse, it is expected that anywhere between 15-40% of the world's trash enters our oceans yearly. What is being done to counteract this. Well, PRI published Two proposals to clean up our oceans of garbage:

I have gathered you all here to persuade you that space exploration is indeed worth the risk despite what a few people think. Those people think that exploration is a complete waste of time and money, but I would have to completely disagree with them because it has many benefits for the human race. Exploration is worth the risk, because it will give us information and resources that we didn’t have access to before we explored that place.

People who think we should explore space more than the ocean might say that with new technology, we are just beginning to discover things outside of our solar system. Well I think that there are so many things on our own planet that we have yet to discover. The ocean is a perfect example of that. In 2010 scientist Santiago Herrera embarked on an expedition in the water near Indonesia to determine areas worth returning for research. "Scientists saw far more than they expected...on this expedition, Herrera says, 'we were never bored because we were constantly seeing amazing species. We suspect this is one of the areas of highest biodiversity on Earth." (page 208) Many people believe that with more expeditions in space, life on other planets or habitable planets will be discovered. I believe there are many, many new species yet to be discovered, especially in the ocean. "To date, scientists have identified more than 1,300 species in deep-sea chemosynthetic habitats. These organisms have introduced us to completely new ways of life and expanded our view of how adaptable life can be." (208) Scientist Craig Smith who is a professor at the University of Hawaii believes that scientists will continue to find new life in surprising locations. As these examples show, exploring the ocean is more important than exploring

Review: The opportunity and endeavor of exploring the Earth’s oceans can reap great rewards for mankind and unravel many of the mysteries that the Earth has left to

In my opinion, the benefits of European exploration did not outweigh the consequences. To support my opinion, this essay will include three topics that each show both pros and cons. Those topics include the Columbian Exchange, Smallpox, and Columbus’s voyages.

There are around 40,000 plants species, 427 mammals, 1,300 birds , 378 reptiles and 400 amphibians and 3000 freshwater fishes. These are just the number of some big animals. But in fact if we count the number of smaller life forms it will be way more the above number. There are more that 100,000

Astonishingly, Did you know that we have better maps of the moon than we do of the ocean? (#7) It’s true! Scientists are working to make drones to explore the deep sea. Ocean Exploration is a developing science that incorporates the use of marine biology and drone technology. Ocean Exploration technology will be an overall benefit to society because 1. exploring the ocean is easier than before and 2. ocean exploration can help with monitoring the deep sea.

One of these creatures are the yeti crabs. These crabs live near the thermal vents at the bottom of the deep sea. Their white color could be due to their obscured environment. There is a reason these crabs are called “yeti crabs”. Yetis have hair, so this would represent the crab’s distinct features. As said in the article, these crabs are “Dubbed ‘yeti crabs’ for their hairy chests and legs, these creatures are new to science” (p.3). This has grown on the crabs over many years to adapt to the thermal vents around its living space. The yeti crab lives in a mixed climate where it is very hot and very cold at the same time. When these two temperatures collide, “chemical reactions produce an array of mineral compounds, which many organisms consider food” (p.2). Animals such as the yeti crab depend on chemistry rather than photosynthesis. Since these crabs are new to science and new to the studies of scientists, they “aren’t sure but conjecture that mineral-eating bacteria might grow on the crabs’ hairs and that the crabs might scoop up the bacteria” (p.3). This differs from the other crabs in the world. Maybe the more the yeti crabs live near the thermal vents, they will adapt even more and evolve

Yeti’s are mythical monsters, who live in southeastern Asia, and are related to bigfoot and yowie. However, there is an even bigger monster who lurks in the shadows of the arctic ocean. The recently discovered yeti crab. This hairy, blind crab is part of the three known species of the yeti crab(Elizabeth Palermo). The crabs live in the South Ocean in Antarctica, “About 8,500 feet down lives Kiwa tyleri the newest member of the yeti crab family” (Jessica Halel). The scientific name for it is Kiwa tyleri. According to Elizabeth Palermo,author of Yeti' Crab's Strange Body Suits Its Hellish Habitat, “for the first time, K. tyleri is the only species of yeti crab known to reside in the Southern Ocean, off Antarctica”. The crabs gather only a few

Unlike the yeti, though just as elusive, the yeti crab is no creature of fable. The yeti crab, also known as Kiwa hirsuta, has introduced not only a new species of crustaceans, but an entirely new and unique genus as well. The genus Kiwa was chosen after the Polynesian goddess of shellfish, and the species name hirsuta represents the crab’s hairy, yeti-like arms. Determined to be a decapod, it is related to crabs, lobster, and shrimp. The creature is differentiated from these by its lack of eyes and its obvious yeti-like appearance. Found on the Pacific-Antarctic ridge near Easter Island, this benthic creature is a very strange spectacle. The deep-sea creature survives in a very specific environment, and uses the hair on its legs for most of

There were a few inventions that made the European exploration possible. One of the inventions was the magnetic compass. This allowed the ships to navigate with nothing but water in sight. Another one was the invention of the caravel. The caravel allowed the ships to sail against the wind. The last invention was more detailed maps. These maps allowed sailors to plot their course for a safer more accurate travel. These were some of the inventions that led the European exploration.
