When analyzing the book Waterlily, by Ella Cara Deloria, it is important to recognize the vital relationship she illustrates between the Dakota Sioux tribe and their values of kinship. The book both incorporates the complex nature of kinship, but also constructs a comprehensive timeline of the traditional lives of the Dakota Sioux and how the interact within their society. Deloria strives at epitomizing how important kinship is in everyday life for the Dakota Sioux; and how it keeps them organized into one exhaustive, organized society, thus allowing them to stand together in solidarity.
The majority of avid paddlers, especially those of us near the U.S. National Whitewater Center here in Charlotte, know that the water quality of the Catawba River is considered “sketchy.” We have grown used to seeing the occasional, inexplicably dead catfish along the river banks and do not seem to question it anymore. What we don’t always realize is that the water quality is much worse than we had originally thought. For example, untreated sewage spills and line leaks from new developments along the river end up contaminating the nearby water, and therefore affect everything downriver from the sites.
An invasive species is an organism (plant, animal, fungi or bacteria) that is not native to the ecosystem. The invasive species can also have a negative effect on the economy, the environment and our health. The great horned owl is not an invasive species but are a species control officer of sorts, by eating mice and other small mammals they keep the population
Eutrophication is a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality.(Cloern, Krantz, & Hogan, 2013)
Manahan (19..) discusses pesticides as water pollutants. DDT was introduced after World War II which accelerated pesticide use. Manahan (19..) states that by the mid-1990s agricultural use of pesticides was over 300 million kg per year and millions more kg of pesticides were used in non-agricultural applications.
Invasive species are “species that is non-native to the ecosystem whose introduction is likely to cause economic and environmental harm”. A example of Invasive species would be the Zebra Mussel. Zebra Mussels or also known as Dreissena polymorpha is a small freshwater mussel. The Zebra Mussels can live up to three-nine years which can grow up to 2 inches. These mussels attach to hard surfaces such as rocks or boats. They were first introduced to the Great lakes in 1988 but were originally from Russian and Ukraine lakes. The Zebra Mussels were first found in Lake St. Claire (one of the 5 great lakes) which within one year they rapidly spread to almost all of the Great Lakes except Lake Superior. This is because Lake Superior is not the ideal
They expand rapidly and spread quickly over wide areas, and out-compete or prey on native species. While all invasive species are non-native species, not all non-native species are invasive unless they meet these guidelines. If they are useful and not harmful to the ecosystem, the non-native species will not be considered invasive.
The first invasive species is the Giant African Snail. It originated from Africa and was first presented to Florida as being a pet. These snails have more than 500 host plants, and if they became native to Florida it would potentially devastate Florida’s agriculture. To remove the snail yo have to search around houses and plants and hand remove them from the environment.They are found around houses because
There are many invasive species that are affecting the Everglades by invading the ecosystem. Many of these species were brought to the everglades by people and animals. They are changing the ecosystem and are competing with natural native inhabitants of that area. The native species have to adapt to the change or move to another area to survive. Both plant and animal species have invaded the area within the Everglades. One plant example that has invaded the Everglades is the Brazilian Pepper Tree. This was first introduced in the 19th Century and came from areas within Argentina, Brazil and Paraguay. This plant species was first brought to the Everglades by birds and then was spread by racoons and possums. It is invasive because it grows very
Traverse City Michigan is a small town in Northern Michigan, with a port, an airport, a rail system running through it, and lots of roads. While there is most likely the most freight carried through trucking on the roads, I would like to talk about the shipping industry. Because Traverse City is located with access to the Lake Michigan there is obviously a great deal of materials shipped over the water.
A hydrilla grows a long steam that has many leaves on it as well as tiny white flowers on them which float above the water. They are an aquatic plant which means they live in water such as clean water, including lakes, ponds, rivers, streams, and marshes. Seen mostly in the Southeast of Florida and in their habitat they form dense mats of vegetation, can grow with little light, and more efficent in taking nutrients than other species. Florida faces many problems within their water bodies and waterways. The aquatic plants pollute 96% of the public lakes and rivers. Hydrilla greatly impact natural cycles as well as recreational means. A hydrilla is a perennial, which means when the weather changes to cold the leaves and stems die, but the roots
Zebra Mussels are an invasive species which now dominate the Great Lakes region, they were introduced in the 1980’s and ever since then their quantities have increased dramatically. Since the time they arrived they have caused many problems including problems in the ecosystem and with the economy. Human’s have been trying ever since their arrival to eliminate or reduce their quantities but not much progress has been made. Right now Zebra Mussels are one of the biggest issues affecting the great lakes.
Minnesota is home to many geological wonders. Whether it be the formidable cliffs of the North Shore, one of thousands of pristine lakes, or the miles of rolling farm land; Minnesota has much to offer. Each state has very different geology, and because of that, each state uses their geology in different ways. The geology of Minnesota plays an important role in many different aspects of our lives including our health, economy, and heritage. If the geology of Minnesota would have been different, there is no doubt that the state would be different today as a result. The wide variety of geological features in Minnesota affect our lives every day.
It is important to establish preventive measures because once present invasive species are hard to eliminate and also cost a lot of money. An example is law passed by Canada and the United States in 2006 which requires ships to treat and flush its ballast water before discharge, this aid in the control of zebra mussel. Electric barriers are also being used in Romeoville, Illinoi to control Asian carp and restrict them from swimming to Lake Michigan. In Ontario the possession and sale of several invasive fish is prohibited. Educating people about the impacts of these invasive species can also lead to enlightenment and boost control. Pesticides such as lampricides and chemicals are being used to target invasive species such as purple loosestrife and sea lamprey. Since prevention is not always guaranteed, these lakes should be closely monitored for invasive species and in a case where it occurs rapid eradication should be practiced to prevent their growth and save further
Lake Erie has been a huge topic for Ohioans due to how polluted the water is. Lake Erie is Ohio's biggest water source, and that being polluted is not good for Ohio and other states that use Lake Erie’s water. Though this is not the first time this has happened before, in 1960 the lake was VERY polluted due to heavy industries lined up on the shore lines. Lake Erie called the “Dead Lake” for how much pollution was in it, and how many dead fish there were.
