Living in the Central Valley, a much debated topic of conversation has been the Delta Smelt. Because of where the species lives, it has caused a lot of controversy for everyone from government officials, farmers, and average citizens. Whether or not to save the Delta Smelt has been part of a heated controversy for years, but often times political agendas overshadow scientific data. Currently, the Delta Smelt is classified as “threatened” by the United States government. By looking at the science behind the situation, I believe it is best to try to save the Delta Smelt. The Delta Smelt lives mainly in California’s San Francisco Bay Delta. It can grow to be only 7 cm. long and lives towards the bottom of the food chain. Serving as an important food source for the other fish in the delta, the smelt is also helpful for scientists as an ecological indicator. Ecologists have used the smelt to measure how healthy the delta ecosystem …show more content…
The environmental risks of saving the fish are often the most debated part of the issue because it affects farming communities. How does this effect the water? How does this affect the people who live in California? The smelt have no negative effect on the water they live in. Because they are native, they only serve a positive purpose as part of the food chain. Closer to home in our very own San Joaquin River, experts at the River Center are working to save the Delta Smelt by educating the masses. Because the river runs from the mountains to the San Francisco Bay, the smelt are native to the valley. Up the road at UC Davis, specialists have been raising and caring for a population of smelt to protect against extinction. It is currently the only place in the United States that reproduces and raises the smelt through ought their whole life cycle. Their goal is to maintain the smelt until the delta conditions improve enough for the fish to survive out of
Policies are often put in place without regards for the effect it will have on other areas, people, or wildlife. Several examples of these unintended consequences are shown in the documentary Salmon: Running the Gauntlet, which explains the effects that human activity, dams, and attempts to repopulate the salmon species have been implemented and failed. With proper evaluation at the onset of a major project, these severe consequences may be avoided.
For example, when the labors take oil from the ocean or sea, the oil may leak from the pipes and it will mingle with water. That time the living things in the sea are destroyed by the polluted water. So many fishes and sea organism may
This is an important topic. It affects the overall health of the population surrounding the Chesapeake Bay, as we eat from it quite often and it can be used as a water source. The chemicals being released into the water are from coal-burning factories and runoff, which can be helped, but it’s almost impractical in this day and age to spend the amount of money required to do so without the technology that can guarantee a fix.
According to the Worldwatch Institute the rapid industrialization has polluted many lakes and streams resulting in chemical pollution and increased algae blooms leaving the water undrinkable. These combined issues are then causing knock on effects to the aquatic life by staving them of oxygen. Many areas are also suffering with an increase in dust storms; these have been a cause of over agricultural use. These increased storms would not cause many problems but now they can ...
Kenneth Schiff wrote an editorial for the Marine Pollution Bulletin in 2014 where he asked environmental scientist about the effectiveness of the Clean Water Act. Three topics were discussed to support their approval; The Cuyahoga River, Platform A and declines in marine life. The Cuyahoga River in Ohio had hit a point 1969 where there was so much oil on the surface of that it caught on fire and now it has been deemed as fishable by the Ohio Environmental Protection Agency, thanks to the Clean Water Act. Platform A was located in Southern California. In 1969, an explosion occurred, causing 100,000 barrels of oil to devastate beaches along the Pacific Ocean and kill thousands of animals located in this region. Also discussed was the effects of hazardous substances, in this example DDT, on marine life. The use of this pesticide caused brown pelicans and California sea lions to experience intense decline in population- thanks to the Clean Water Act being followed by much research, restrictions and bans were able to be placed on these chemicals, allowing these populations to flourish once more. Within this editorial, there is also many who state that this Act has not been effective enough. One big argument is that the EPA has a list of pollutants that has not changed since the 1970’s yet in the last 40 years, there has
Generation after generation gathered food off the land, people are continuing to practice this in our modern world today. Societies expressly continue to gather their own food as it provides an inexpensive, delightful tasting meal. One of the techniques of our historical past that is still in use today, that has been used for generation after generation is “netting” fish. Netting is a classic technique that has not faced as many revisions to its practice. It persists from one generation to the next due to the fact, that many do not understand it to be harmful to the environment; others may enjoy the idea of letting commercial fisheries catch large numbers of fish as it continues to keep some of Americans favorite meals low cost. Devastating fall out from neglectful thinking about netting will occur in the future if preservative action toward this way of life is not taken. Minimizing the use of nets in waterways will ensure salmon and other fish survive for many more generations to come, allowing this plentiful food source given to us by Mother Nature to be exploited and enjoyed by our future kin. With food sources now readily available, fishing with nets should be reevaluated as follows; who is allowed to fish with nets, what are their purposes, and how will this effect tributary fishing populations.
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
Then the documentary tackles Puget Sound. The Duwamish River is the largest hot spot in the nation. In 2001, the Duwamish River was classified as a “Super Fund” site. This is given to a site that will receive federal assistance for clean up. But yet, it may be too late. Puget Sound in contaminated with PCP, lead and mercury. The threat comes from the giant industrial polluters of old and from chemicals in consumers’ face creams, deodorants, prescription medicines and household cleaners that find their way into sewers, storm drains, eventually into America’s waterways and drinking water.

With a coastline of over 202 000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around 5$ billion dollars a year, being one of the world’s most valuable. However, the coasts have not been treated by respect; overfishing, over consumption, and wasteful practices has deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries has been project for 2048. Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large specie, the cod.
The topical focus of this paper is the Atlantic salmon fishery. In particular, this paper looks at habitat loss and salmon farming both of which have had major impacts on the sustainability of the fishery. Several efforts have been made to restore Atlantic salmon to their native habitat, specifically in Maine and New Hampshire. This paper reviews the policies that have been implemented, not yet implemented, and a proposed policy.
Water pollution has had devastating effects on the environment, which include irreversible effects to the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousand of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever; unless there is a balance. We must protect the resources we have in order for them to last into the next generation. Every time we throw away a plastic bottle, drive our cars, and even burn those millions of fossil fuels to operate all those huge factories, there is a chance it will pollute the ocean and eventually effect the way we live. There should be stricter laws regulating human pollution, in order to protect our oceans ecosystem.
Some of the species being threatened by pollution include: dolphins, porpoises, penguins, sharks, and polar bears. B. Humans are also being affected. 1. Clean water is needed for good human and animal health, but as DoSomething.org states, over 1 billion people worldwide don’t have a means of getting clean drinking water, an... ... middle of paper ... ...
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
Water pollution is also a major thing in the world because almost 60% of it is fishes. It occurs due to several factors; the industrial waste dumped into the rivers and other water body’s cause am imbalance in the water leading to its severe contamination and deaths. And the infamous Global warming is the emission of greenhouse gases particularly CO2 is leading to global warming.
