Contributions to the Great West There are many components to the West that helps in the settlement of it. Those components including mining, cattle raising, and farming. Mining was very popular at prior to during this time period. The 49ers of California and the 59ers of Nevada led to even more gold digging in the 1860’s. Nevada became a popular gold digging location after the Comstock Lode had been uncovered and 340 million dollars worth of gold and silver had been found.
Recognized by many as the “smeltdown in the Delta,” the extinction trajectory of delta smelt, has left the once-abundant species in critical condition due to record-high water diversions, pollutants, and harmful nonnative species that thrive in the damaged delta habitat. The delta smelt is semelparous, living one year and dying after its first spawning. Delta smelt spawning occurs in spring in river channels and tidally influenced backwater sloughs upstream of the mixing zone where saltwater meets freshwater. This shift in the species center of abundance arises from the fact that while the delta smelt is a saltwater tolerant species, it is seldom found where sea
According to Everglades.org, they’ve “contributed to nearly 70 percent of extinctions in the United States” and are the “primary cause of species endangerment.” The water itself is a major cause of decline to the area, firstly because of poor water management leading to water levels being too low or too high at the wrong times has caused a decline in many species. Secondly, poor water quality has had devastating consequences. The pollution and an abundance of toxins and nutrients has helped to kill off many living things in the
For many decades, water pollution has been a major environmental issue. "Water pollution is the contamination of water bodies and occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds" (Wales). Lake Huron, which is known as the third largest of the lakes by volume of Great Lakes, (Lakes Huron) water quality has been of major concern. Few major sources identified were faulty septic systems and agriculture. Some of the effects caused by the pollution included: disruption of aquatic life, elevated levels of nitrates and phosphates from polluted underground water, swimming prevention, and numerous outbreaks of Avian Botulism.
This is due to de-industrialisation as the regions mining industries have now long gone and they now depend highly on tourism. The flood, in short term affected Boscastle considerably, Shops that survived the impact and bombardment of the water were too flooded to open and had to be repaired. This on average for buildings and houses cost in between £15,000 - £30,000 and the total cost of the flood was £50 million! This caused a big dip in the local economy had to pay out for all the damages without getting much money put in! And also due to the shops closing, the people ended up loosing there jobs.
Referring to the Canadian Energy Research Institute, it has become evident that oil sands have impacted nearly every community within Canada, exponentially increasing the need for new job opportunities and economic growth. Since Alberta has one of the largest oil reserves within Canada, the petroleum industry has impacted “…over 239,000 Albertans”(Canada’s Industry 2012). However, with a closer eye on the impact of oil sands on the economy, it is proven that these oil sands provide jobs outside the country as well. Such as the services, and materials which are used in the construction of oil sands, come from not only across Canada, but also form many other foreign countries. Many components are needed for a process which seems so simple.
In 1611, just 4 years later, 80% of the 500 settlers, including women and children, were dead. Many people had a word to say when it came to Jamestown’s credibility concerning the environment. Even though it seemed as if there was a great source of water, it didn’t turn out that way. The island was not reliable when it came to natural food abundance. Due to its high tides and adjacent river to the creek, the water became brackish water, a mixture of fresh water, salt water and human waste.
Furthermore, it would also have a heavy influence on the amount and quality of farming. If the water were to become polluted due to human contamination, then that would result in even less fresh water for farming food. This would be extremely detrimental due to the fact that the population of California is expected to grow from 35 million to 55 million by 2050. Therefore, resources would become even scarcer, and prices, in turn, will sky rocket. Each of these components are a recipe for failure, and would leave the southern part of the state-which contains two-thirds of the state’s population-with very little fresh water
It was literally a dumping ground and it even caught on fire a few times due to the toxic wastes. The phosphorus levels in Lake Erie are increasing due to the pollution causing harm to the fishes that reside in it. In 2014, Lake Erie had so much algae from pollution that it caused the City of Toledo to be left without fresh water. This algae was caused by the excessive amount of phosphorus in the lake. This excessive amount of Phosphorus is caused when the fertilizer is dumped into the lake by farmers.
According to Frazer (2008), a majority of salmon aquaculture in the Pacific Northwest consists of non-native Atlantic salmon. This is an issue according to Simberloff (2009), because after changes to habitat, research indicates that, “… the second greatest cause of species endangerment and extinction [is introduced species] …” (p. 2). There are several factors associated with invasive species, not the least of which is the spread of disease. Bakke & Harris (1998, as cited in Frazer, 2008) mentioned that hundreds of infections that are rare in wild Atlantic salmon populations are prevalent in farm raised Atlantic salmon. Escaped farmed salmon are then capable of spreading these infections to wild Pacific salmon populations.
