San Diego County’s plan for a desalination plant should not be put forth. To start it will harm the sea life in the area, it’ll be terrible for the ocean, and the project takes the people’s money. If the plant is put into action, sea life will be chaotic in the area. “... 80 percent of tiny organisms - including fish eggs - will be sucked into the desalination plant and killed”. Although it may seem like just “tiny organisms” being killed, but the, “Many small lifeforms that fish depend on for food would be destroyed”. As it says from the NewsELA article “California tries one solution to water problems - treating seawater”. If the plant takes place, the whole ecosystem would take a toll. With less food for fish, there will be less fish themselves. This is a problem for other wildlife, and for some markets and businesses. The plant would not be good for the ecosystem, and economics. …show more content…
You’d be wrong. In fact “To produce 50 million gallons per day of freshwater, Carlsbad will draw in 100 million gallons of seawater”. Worse yet “The discharge water is so salty that it does not dissolve well in water”. This means that every gallon of freshwater the plant creates, it produces a discharge gallon that is twenty percent saltier, that is released back into the ocean. If San Diego Plans to turn 56 million gallons of seawater to freshwater everyday, it is expected to release another 56 million gallons of discharged water. These discharges make for areas of water where sea life can no longer live, including the plants and
cut back on the problems in the Bay. Scientists have given an unthinkable amount of attention to the Bay of the past several years and researchers from countless numbers of agencies and institutions have dove deep into the issues and studying every nook and cranny to create answers to every politicians’ questions. The biggest concern with the Bay, and the most concentrated ...
Considering the fact that Marc has both been sweating and drinking minimal amounts of water, Marc is now dehydrated. This means he has less than the required amount of water for his body to complete the processes necessary to maintain its health. As stated in the question, the process of sweating causes the loss of more water than solutes. This means that as the level of water decreases, the level of solute concentration will increase, creating a change in the water to solute ratio.

The dead zone in the Gulf of Mexico is a human problem, like most other disasters. What this means is that once the place thrived and was ecologically balanced, but we tipped the balance slightly and wrecked havoc upon the environment. It has been noted to occur since the 1950’s and is ongoing. The reason that this dead zone occurs is because of a phenomenon known as eutrophication. Eutrophication is when there is an excessive amount of nutrients in a body of water and it causes an abundance of plants to grow. In this case the nearby farms had been using nitrogen in their fertilizers. The nitrogen got carried into the ocean through rain and other forms of water. Nitrogen is an important aspect for plants to grow and a lack of it is normally what contains plants from growing in an excessive amount. Because farmers mainly use this, the dead zone has a considerable decrease in size in the winter season while it increases in size during the warm seasons. Eutrophication generally leads to another phenomenon know as hypoxia, which is the state of water when it is lacking oxygen. Having too much nitrogen leads to hypoxia, because there is a bloom in algae. Bacteria in the water then eat the algae and use all the oxygen in the process. Without oxygen in the water, a dead zone is formed, an area with little to no life. The dead zone in the Gulf of Mexico is around 6,000-7,000 square miles in size, but varies throughout seasons (source23879482371) (see Fig. 1).
The purpose of this experiment is to investigate the effect of changing the concentration of sodium chloride solution on the rate of osmosis in tubes of potatoes. This was maintained using equal measurements of the potato tubes and applying them into the different concentrations of sodium chloride, 0%, 2%, 5%, 10%, 20% and 26%, in beakers then measuring the change in mass of the potato tubes afterwards. The time taken for all potato tubes to be placed in solution was 15 minutes. Can the concentration gradient of the sodium chloride solution influence on the rate of osmotic diffusion undergone by the potato tubes?
Farming is a $1 billion industry and nearby farmers need to dispose of agricultural drainage so that their crops would continue to thrive (McClurg). Farms have needed a place to drain water from their fields and they have been draining it into the Salton Sea since the 1920’s (McClurg). Unfortunately, the pollution caused by the drainage has caused further damage to the economy because of the loss of tourism. In the 1980’s the Salton Sea used to generate $300 million for the local economy (McClurg). Today tourism and the money the lake used to generate has been declining rapidly because of the pollution (McClung). Fixing the Salton Sea so that it can be used for agriculture, wildlife, and tourism will be extremely expensive to California in the future (James). “California has a new $383 million plan for the shrinking Salton Sea” in the short term but the long-term plan could cost “between $1.5 and $2 billion” (James).
Osmosis is the facilitated diffusion of water across the cell membrane of a cell. The inside layer of the cell membrane is hydrophilic, meaning water cannot easily pass through the membrane. The cell membrane has to have aquaporins, which are water channel proteins, that move the water across the membrane. If there is a water and salt solution outside the cell, the salt can enter the cell by diffusion, but the cell membrane is not permeable to the water. Because there is more solute solution inside the cell, there is less water. The aquaporins move the water across the membrane until equilibrium is reached.
Terrell (2015) states that the three inch delta smelt was decided to be in danger of going extinct a little more than twenty years ago. The U.S. Fish and Wildlife Service has claimed that systems used by farmers to retrieve water from the delta have added to the dropping number of delta smelt. Conservationists think it is necessary for people and farmers to take their water from sources other than the delta in order to preserve the characteristics of the delta (Terrell, 2015). Dr. Peter Moyle of UC Davis stated in an interview,“We have 80 fish species in California, like the delta smelt, that are in trouble” (Cited in Terrell, 2015, p.12). Moyle insists that it is more than just the three inch delta smelt that is in danger, it is at least seventy-nine other species that need protecting as well. As interviewed by Siegler (2015), senior water rights farmer, Rudy Mussi knows the importance of the delta and preserving it, not just so he can use its water on his fields, but also to keep it alive for the future. It has been suggested that water be taken out of the delta and moved to farmers in the lower portion of California who have junior water rights (Siegler, 2015). The delta cannot be overused because it is important that the ratio of saltwater to freshwater stays the same in order to preserve the fish population. In 2014 the excess water that came from the delta, the environment in which the fish live, added up to almost two hundred fifty billion gallons of water or enough for over six and a half million people each year (“Water wars”, 2015) While these people cannot easily access this water source, some farmers are able to use limited amounts of water if they farm on the delta, creating an issue between the junior water rights farmers

The city deserves reliable water supplies, “The project has been in operation for over half a century and the whole fabric of the community here has been built on having those reliable water supplies,”(10 W). This project worked for fifty years, and now the city relies on it. The water supplies provide water to bathe, drink, and swim which most people need to do in order to stay in good health. This helps everyone do their daily activities and work. Why would anyone go against a plan that works and benefits everyone, “...politics that make this project so remarkable,” (2 W). Politicians do not want to spend money on mindless projects; they want their money to go to good organizations. This exhibit that the project a chance at a trustworthy cause. Politicians know the risk, and they have confidence that it will work. There can be a compromise between the farmers and the fish, “The same water that restores the salmon could then be pumped back uphill and used again, this time for irrigation,” (9 W). We also give the salmon they need while also giving back the farmers their water. The river helps the salmon go back to their nest, then lay their eggs, and farmers can water their crops, and sell it to the market. This way everyone can be at peace, and get what they
There is a terrible drought in California and we needed a solution so that everyone has access to clean and drinkable water. Good thing for us there is a solution, they turned saltwater into freshwater by excluding all the salt from the water and making it so people can drink it. The solution before was that they had ships come and deliver water from different areas of the country and different areas from the states.
Before delving in to what is actually wrong with seawater desalination plants, it is important to establish that there are plenty of alternatives available. One of the best alternatives is to adopt more efficient practices, such as conservation of water, and recycling storm water and grey water (from washing machines and bathrooms...
The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. When dangerous substances go into the ocean, ecosystems are suffer and become endangered along with lives of people and of marine life. Surfrider Foundation recognizes the importance of protecting and preserving the quality and biodiversity of the world's coasts because they are truly irreplaceable. There is also historical evidence of ocean pollution being present in the past, but the problem still lingers today. Heal the Bay discovered that,“Did you know there is a DDT and PCB hot spot off the coast of Palos Verdes? This superfund site (which indicates it's one of the most polluted places in the United States), is left over from a 1930's era chemical plant. Because DDT takes so long to break down in the marine environment, it persists to this day, contaminating certain species of fish. There are also highly polluted sediments in the Long Beach area, a sign of the heavy shipping in the port. Heal the Bay works on developing effective capping and removal plans to keep those toxins from spreading” (Heal the Bay). DDT is still highly concentrated in the South Bay area and still contaminating different species of fish. Even after more than 80 years DDT, a toxic insecticide, is still very concentrated and during upwellings, DDT particles come back up and continue to harm marine life. If humans are careless about what is thrown on the floor or sprayed on lawns, it can lead to disastrous affects when it comes to the condition of the ocean's ecosystems, and can endanger life itself leading to a problem that only we can mend.
