In the deep sea resides black smokers, which are hydrothermal vents. Black smokers form from tectonic plates meeting and this creates a mineral laden fluid, iron sulfide, hence the “black smoke”. This water permeates through the earth’s crust, boils, and dissolves rock, reacting and creating bubbling, nutritious water. Only few organisms can live in the cold, deep, and empty environment where these Black smokers exists. These microbes are called extremophiles and rely on chemosynthesis, a process where an organism absorbs chemical energy from mineral-rich processes. These extremophiles, also known as archaebacteria, are an important food source for certain sea life like the yeti crab and sometimes have a symbiotic relationship with larger organisms. Discovering more of these microbes could further society as we could find more on other planets and their resistance to extreme environments can be studied by bioengineers. These hydrovents are also more concentrated than mines above the sea, which could potentially provide a cause for underwater sea mining. Such reserves are not only looked upon as a new mining source, but also a renewable mining source since these chimneys are capable of regenerating over time. Taking advantage of hydrovents would expand the mining industry and provide more jobs for society, reducing poverty while increasing …show more content…
In order to collect samples, our two concepts could have two separate internal storage areas for bacteria samples and seabed samples. To collect samples, the concepts would need to open up its internal storage and collect samples by either letting water flow or scraping the floor. Once the samples are in the internal storage professionals would await on the surface for samples to come back up. These professionals would send the rover or drone up and down constantly for multiple samples a day in different areas of the
Based on the combined data provided by two surveys suggest that cell phones and smartphones are not just a practical alternative tool suitable to be used in smoking cessation program. Mobile phones are freely accessible and thus can be a functional source that could provide those who want quite a discrete avenue to do so. The same can be said for the opposite as mobile phones can also provide a public forum for those who want to intervene and force someone they know to quit smoking cigarettes.
To understand the current culture of smoking at Wilkes University, research about smoking among college students was analyzed, a survey was given to the University body, and a national smoke-free day was held to promote a wave of change towards a smoke-free campus culture. During the Fall 2015 semester, the well-being of Wilkes University was improved with the establishment of a smoking policy. The health problems associated with smoking are reasons why establishing policies on college campuses are necessary.It is no secret that smoking tobacco can harm nearly every organ in the body. Specifically, smoking tobacco can cause autoimmune diseases, affect bone density, harm blood cells and damage the function of the heart. It can also negatively
I think that people are being selfish and not thinking about the environment and these hydrothermal vents. Also the evidence for why mining near hydrothermal vents is much stronger than why it’s beneficial. People say it’s beneficial because there’s no acid mine drainage, or that mining does not affect active black smokers and lastly, that the sulfide deposits are on the seafloor so there is not any waste rock piles. Many people believe that the hydrothermal vent creatures could be what the early life had evolved from. Comparing these weak evidence about why mining near hydrothermal vents is beneficial to why it is not good is hilarious. People mine for gold, silver, copper, zinc and lead from hydrothermal vents deposits. It may be an easier

The 2017-2018 Ethics case of Smokers Need Not Apply presented the issue of tobacco use amongst hospital employees. The hospital job posting had stated that smokers need not apply, as concerns regarding, “the interests of employee productivity, as well as saving on the cost of employees’ health insurance” have become major hiring considerations (NHSEB, 2017, p. 7). This job application caused much controversy amongst smoke-free advocates and the pro-smoking community. After deep analyzation of this case, I would like to answer the question presented: “when, if ever, is it morally permissible for employers to discriminate on the basis of tobacco use?” (NHSEB, 2017, p. 7). In addition to clarifying my final answer, I would like to use the theory
The claim is the same as the evidence, scientists discovered biological communities unexpectedly living around seafloor hydrothermal vents, far from sunlight and thriving on a chemical soup rich in hydrogen, carbon dioxide, and sulfur, spewing from the geysers.Inspired by these findings, scientists later proposed that hydrothermal vents provided an ideal environment with all the ingredients needed for microbial life to emerge on early Earth. researchers went to hydrothermal vent sites where the chemistry predicted they would find a lot of methane, and others where very little was predicted to form. they measured 38 hydrothermal fluids from Mid-Atlantic Ridge, Guaymas Basin, the East Pacific Rise, and the Mid-Cayman A central figure in this hypothesis is a simple sulfur-containing carbon compound called methane. Scientists suspected methane to have started
As scientists, particularly astrobiologists, learn more about life on Earth our perception of is habitable is changing 7. The discovery of life living my mid ocean ridge geothermal vents in the 1970’s is a classic example of this. Before it was thought that life could not exist without light from the sun. By these geothermal vents organisms exist, completely cut off from other ecosystems. These vents are often thousands of kilometers below sea level and most receive no light from the sun. They also exist under a high pressure environment. Some of these organisms, or extremophiles, are complex organisms that feed off the minerals emitted from the vent in a process called
Both marijuana and cigarettes should be made illegal because they both cause cancer, messes up lungs, and how a person ages. What is Marijuana? Marijuana an illegal drug that, it is dried and rolled into paper like a cigarette, it can even be smoke out of bottles, pipes, and is also smoked out of bongs (Mezinski). And marijuana can be healthy for you if it is eaten, eating it will affect you more or less depending on its percent, and the age of it’s THC (Mezinski). Marijuana has a lot of the same cancer cause chemicals that is tobacco, it holds over 400 different chemicals in it and because of the the chemical that gives you something called the “munchies”, the munchies makes you feel very hungry (Gross). Marijuana relaxes the air tubes
are preventable (US Department of Health & Human Services, 2014). Additionally, the health care costs of smoking amount to $96 billion each year (Barendregt et al., 1997). Yet, this is an underestimate of the total costs of smoking because of the many externalities associated with cigarette consumption. Clean-up and secondhand smoke are two common examples of these externalities. For instance, cigarette butts
Ultimately, we are taught that stealing is an inappropriate act to obtain the things that we want. However, in this situation the doctor was being irrational with a drug that was meant to save a life. The doctor was taking advantage of Heinz’s circumstances and was inconsiderate to the wife’s need of the drug. Doctors are supposed to take oaths in which they do everything possible to help a patient in need. Heinz had every intention to pay for the drug, however the doctor’s unwillingness to negotiate led Heinz to steal. Heinz was just seeking the well-being of his loved one. Therefore, Heinz should have stolen the drug for the well-being of his wife.
The discovery of the hydrothermal vents along the Galapagos Riff led to the identification of chemoautotrophic symbiosis. These vents are widespread along the sea floor. They release sulfide, methane, and heat from beneath the Earth’s crust, they provide homes for the organisms to attach to and food for them to consume. The chemotrophs use the elements and energy within these vents as food and cycle the energy up the food chain. Iron
Well, at least you are man enough to admit up front that my friend was telling the truth. Far better for a lad to face up to his faults, rather than putting forward excuses and trying to obscure the truth. But, as is often the case with you recently, lad, a positive is balanced out by a negative. If you know how angry I will be and how disappointed I will be with you, why do you keep on smoking these shaggin' cigarettes? I had hoped that your last two thrashings would have driven the message deep into your brain and helped you resist the temptation of a cigarette. Given that those thrashings were so recent, but still had such little effect on you, lad, leads me to conclude that they were nowhere near severe enough. On Saturday, you're going
Next the value of hydrothermal vents go beyond minerals.The vents have a bio-organism that is very important to us.In the fact that these microbes have somrthing in them that can cure cancer.These
If you’ve watched television it’s likely you know about the no cigarette law campaign, over the years there has been less smokers and nevertheless a campaign came along trying to make an anti-cigarette law. As a critical thinker, i decided there should NOT be a anti-cigarette law but, I do agree with the message to rid of smoking.
Smoking is established as a recognized cause of cancer, lung disease, coronary heart disease, and stroke(US Public Health Service,1964,Doll R 1976,1994, US Department of Health and Human Services,1989).it is considered to be the single most important avoidable cause of premature morbidity and mortality in the world. WHO has estimated that there are about 1100 million smokers worldwide; this represents about one-third of the global population aged over 15 years (WHO,1997). About 73% of these smokers (700 million males, 100 million females) are in developing countries; in industrialized countries there are 200 million male smokers and 100 million female smokers. In the over 15-year-old population of developing countries, it is estimated that about 48% of males and 7% of females are smokers. The corresponding figures for industrialized countries are 42% for males and 24% for females (WHO,1997).
