They should not mine hydrothermal vents. Mining them sea life is put at risk. By mining the sea life is inured and or killed. Along with sea life the ecosystem is also killed. The chemicals produced from this process kills anything in it’s path. Although many bad things happen they do receive some good things out of this process, like learning more about our earth. While the machines are under the ocean they discover many new minerals and important things. Hydrothermal vents are dangerous and shouldn’t be used as much as they are now. This method has more negative effects rather than positive ones. Sea life is put at a major risk. Using the process causes, utter darkness, intense ocean pressure, and hot acid fluids. Many rare species would
Most of the effects discussed are irreversible and negatively affect the human and biophysical environments. The most problematic effects are decrease in air and water quality, which directly affect not only human health, but health of other organisms within ecosystems in Vanderhoof, collapsing the food chain. I, therefore, hope my concerns are evaluated and appropriate mitigation methods implemented, if the government decides to approve this project.
...: The data shows that if there is minimal or extreme acidification in water then oceanic life will be experiencing severe stress. The findings show that my hypothesis was proven correct. Due to this project being a mini projection of the entire ocean it is clear that if humans continue adding chemicals into the ocean then the acidification will rise putting unwanted stress to the fish.
Environmental problems with this are that a huge marine ecosystem has been devastated. Hundreds upon thousands of marine life have been killed, along with the destruction...
Drill can destroy habitats; disrupt animal life force people to give up their traditional way of living their lives. However, Alaska has a very poor economy and drilling there would create jobs and help to bring money back to the area.
...mize the dispersal of the concentrated seawater. This allowed for the brine to be a lesser threat to ocean life especially at the bottom.
Offshore oil drilling has had so many issues recently. It is time to put a stop to it before we completely poison our oceans. So much environmental damage has occurred from this act. The actions being Many people do not support it and think that we need to protect our oceans.
Back in the early 1900s and modern-day, in mines the tunnels, shafts and caves weren't always safe to work in. Miners would often be trapped in collapsed shafts resulting in minor and major injuries, maybe even causing fatalities. For example, in the autobiography, Rocket Boys, the coal mine suffers a cave in, killing one along with Homer's dad nearly loosing an
...of sodium cyanide is released into a target area in order to stun fish. This method of fishing is used mainly for the capture of aquarium fish, to be sold to wealthier countries, but it is also used for catching food fish. Hundreds of thousands of pounds of cyanide are released into the Pilipino reefs each year. As you can imagine, pumping large quantities of toxins into a fragile ecosystem has negative effects. Even low concentrations of cyanide inhibits photosynthesis in zooxanthellae, a genus of algae with which coral grows symbiotically. The death of the algae removes the major food source of the coral, causing bleaching and death. The cyanide also harms the coral directly, blocking the oxygen-transporting proteins, and preventing oxygen from reaching the cells, causing death.
The drilling will destroy the fragile habitat which supports many endangered species. We all have an interest in this issue. While the oil the industry extracts is used to power the things we need in our everyday lives, it also pollutes the Earth and ads to global warming. The company says that drilling in this wildlife reserves is the only solution to oil shortages claiming: "the easy pockets around the world have already gone." They claim we are running short of oil and this is the only answer.
Warmer water temperature discharged by waste industrial heat into water can affect many aquatic species that cannot tolerate the warmth. A higher level of temperature can result in low oxygen concentrations by speeding up the rate of decomposition of organic matter. "The discharges are often associated with coal-or nuclear-fuelled power plants, and sometimes with large factories." (H.J. Dorcey). The increase of heat materials dumped into water can increase the temperature level in the water bodies and can affect all living organisms within that body. There are many disadvantaging technology which has been affecting water and raising the water temperature from normal. For example, electric power plants might withdraw water from nearby water bodies for the purpose of cooling in the plant and then return the heated water back to the same water body. This is insanely affecting the regular temperature. If the water is not the same, it can lead to many damages within the water body. For example, fishes will dies exhausted from the warmth and it will also affect other aquatic organisms causing them to boil in the water caused by others, sacrificing these creatures. Water from excessively heating up can be best prevented by using special cooling towers and ponds that disperse the energy into the
You see a world like no other. Life is abundant and it is all around you. There are strange creatures living in conditions that are extremely deadly. Before 1997 this world existed unknown, lurking in the dark. The only way for you to see this world is to be in a specialized submarine, otherwise you would die from heat, pressure, and extreme levels of toxins. And yet, in the hostile conditions life not only exists, it thrives. That world is here on Earth and it is like no other. The strange world described above was the deep ocean. At depths up to 40,000 feet or more life is abundant around mysterious natural landforms known as hydrothermal vents. Despite the fragile, beautiful, important life at these hydrothermal vents many companies are looking at them as little more than deposits to strip bare for minerals. Samples have been taken and mineral rights have been given to companies to mine these vents. No full mining projects are under way just yet, but they are coming in the near future. If the mining of hydrothermal vents continues unique, important life forms will be destroyed along with the Earth's oceans. The technology used to extract the minerals is harmful to the ocean and its life forms. Also, some have looked at the hydrothermal vents for easy places to dump nuclear waste, according to a document discussing the exploration of the deep sea titled “Oceanography 1998: Exploring the Ocean Abyss.” The damage and obstacles required to mine these vents would not be worth the mineral wealth. These hydrothermal vents need to be respected and preserved; furthermore the expansion of mining them must not continue. Instead hydrothermal vents could be safely observed with minimal samples taken for research.
Imagine a lush underwater place. Beautiful structures colorful animals and places that would never have been thought of before. In reality that's not what it really looks like, really the ocean is a desolate place that is barren like a desert. Many marine species have been lost by as much as 49%.(seeker) A big part of that reason is because of coral bleaching which causes as stated above a decline in species that depend on the coral as there home. Coral bleaching is a serious problem that could cause problems for everyone if we don’t fix it.

Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes, and similar uses are still found in Iceland, Turkey, and Japan. The true source of geothermal energy is believed to come from radioactive decay occurring deep within the earth.
Thermal pollution is harmful to aquatic ecosystems. They are caused when cool river water are drawn from the water source, run through a power plant, and then discharged back into the same source. This now heated water causes all kinds of mischief and damages to the health of the organisms in the aquatic environment and the environment itself. In an experiment, Gisela Lannig and Inna Sokolova of the University of North Carolina in Charlotte incubated oysters at one of three temperatures, 20°C, 24°C, and 28°C. The differing temperatures of the environment each group of oysters are exposed to in the incubator simulate thermal pollution in the oysters’ natural habitat. What they found was that "the rate of oxygen use, which can be an indicator of physical stress, was three times as high in oysters kept at the warmest temperature as it was in those kept at the coolest" (Raloff, 2005). This reveals that their environment could stress aquatic organisms with just a minute change in the temperature of the ecosystem. This stress could cause the health of an organism to deteriorate or even possibly death.
