What Is Convenience Sharing According To Anderson's In My Opinion

This paper can be an excellent source for anyone researching into how to fight overpopulation. Hardin provides several other viewpoints that show he did not selectively choose evidence or distort it. Hardin proceeds from point to point logically which allowed the reader to comprehend the main idea effortlessly. The author glided to how the people of poor

The conquering and development of natural land has in the past, been seen as a mark of human civilization. In the United States, our progress is often measured by growth and development, but should this be re-examined? There are many opinions on the subject of urban sprawl and its effects on wildlife, but one thing is for certain, we are expanding. From 1955 to 2005, urban and suburban areas grew by 300%, however, the population only increased by 75% over the same period (Ewing, Kostyack and Chen). According to NatureServe, a non-profit conservation organization, urban sprawl threatens one of every three endangered species in the United States. NatureServe’s analysis states, “rare and endangered species data shows that three-fifths (60

Dr. Forsyth implements plenty of evidence as well as proven statistics to back up his outlook on these issues. The growth of human population is happening at an exponential rate, implying that in a short period of time population growth will double. “We find it difficult to comprehend exponential growth, but it may prove to be our fatal blind spot” [3]. When analysing the world’s population over a long period of time, it took roughly 19,000 years for the world’s population to go from 5million people to 500 million people in 1500 A.D. [4] With an estimated population of 7.5 billion people [5], for a period less than 1000 years, population increased more than 1500 times its size than it was in the 1500’s. In addition, on a more minute scale of time, in 1950 the world’s population was roughly 2.5 billion people [6] in merely 50 years the world’s population has tripled. With these statics, it is evident that the world’s population is increasing at an incomprehensive rate. With populations at their peak, overconsumption is another problem this world faces, as Dr. Forsyth affirms “humans consume far more than their fair share of the Earth’s natural productivity.”[7] Due to this over consumption of resources, there is a vast demand for cheap food which results in the clear cutting of large forest to generate room for new plantations of food. When doing so, humans destroy habitats that

Can the most high-tech, compact, thoroughly monitored development still pose an unacceptable risk to the wilderness? In a situation such as this where the natural environment is at a serious risk and the public and decision makers are in a dispute, we must all turn to trained scientists in order to more precisely determine what is at risk and which outcome will serve all parties the best.

Although Slavery was the most profitable to the Southern Planters, there were some alternatives. For instance, sharecropping was an alternative that would easily remove the need for slaves. Sharecropping was the process of a farmland owner renting out space for poorer farmers to use, in exchange for a small portion of their crops to the owner of the farmland. This was actually done a lot after the civil war, when slavery was abolished, and the newly freed slaves needed work in order to support themselves and their families. However, this process was still not put into effect largely until the Union had won the civil war. This is since sharecropping didn’t provide as much of an economic boom to landowners as slavery did to plantation owners,

No matter how many people do claim overpopulation is not a relevant issue, it very much is because of the simple fact that starvation and pollution are very real and existing issues that are ultimately offset by overpopulation. In an article titled “Overpopulation Is Not the Problem,” author Erle C. Ellis uses the analogy “Like bacteria in a petri dish, our exploding numbers are reaching the limits of a finite planet, with dire consequences,” to argue that overpopulation is not a problem by stating the opposing claim. “We are nothing like bacteria in a petri dish,” Mr. Ellis solemnly asserts, “...these claims demonstrate a profound misunderstanding of the ecology of human systems. The conditions that sustain humanity are not natural and never have been. Since prehistory, human populations have used technologies and engineered ecosystems to sustain

Second, the reading states that park wildlife was affected as well. In contrast, the professor in the lecture averts that the small plants that grow create ideal

There were many ways that Reconstruction tried to benefit the freed men, but only ended up making things worse. The practice of sharecropping was invented as a way for blacks to receive an income, since they only knew how to work on a plantation and were limited in job opportunities in the South.. Former slaves would work on land rented from a landlord, which sometimes belonged to their former masters. While these freedmen worked on the land, they received a share of the crop that they had farmed. Sharecroppers needed necessities while doing this work, such as food and clothing, so they had to borrow money from their landlords. This would make it hard for blacks to save money for themselves as they were always in debt from loans. Some say this

Biodiversity loss threatens to disrupt the function of ecosystems, with the potential of consequences for humans as well. Often this loss is measured by species extinction rates, but considerations should be made to include population diversity with measures including changes in size, number, distribution and genetic composition of population and potential implications those changes may have (Luck et al., 2003). Avise (2004) goes as far as to say biodiversity is genetic

Rich’s presentation was interesting, especially in hearing about research being conducted from a geological perspective as opposed to a biological perspective. The presentation was very organized and followed a sequential order. He demonstrated a great interest and knowledge in his presentation through the use of geological terms and well thought out responses to questions from the audience. During the presentation, Dr. Rich took the time to briefly explain certain geological terms to the audience in order for the audience to have a better understanding of the research and its findings. Most of the presentation seemed to be focused on the research of others rather than his own research. At times, he seemed to lose his place on what to talk about next or would dwell on one topic longer than others. The overarching message of Dr. Rich’s research is to make it obvious to the public that the ecosystems of sand dunes are crucial, but in danger of becoming extinct along with its inhabitants. The main thing that can be done now to save them is to preserve the areas and allow them to thrive on their own without any outside

We begin with Anderson’s In My Opinion, where he launches an attack on two topics: convenience sampling and indices as measures of relative abundance. Convenience sampling is where data subjectively taken from locations close to roads, trails or campsites as opposed to any method of random sampling. According to Anderson, the main problems with this is that you cannot make strong inferences about the population as a whole, and that there is no was to look at the precision of estimated parameters. The other issue was how rough counts (index values) were being treated as equivalents to relative abundance. Here Anderson says the problem is that this rests on “absurd” assumptions – that the idea is inherently an assumption, and that the detection

As stated previously, Western conservation models are not universal; conservation efforts with a biocentric focus can be detrimental when applied to the Third

The authors often restate their hypothesis multiple times to clarify to readers the intent of their research. “In other words, a decline in abundance in the source population in one year will result in a decline in the sink population in the following year, as a smaller source population produces fewer young to

Ever since the beginning of recorded human history food production has always limited how much the human population can grow. The Malthusian Trap is a theory that as improvements are made to food production the total human population will increase proportionally to the increased food production. During the industrial revolution, many industrialized countries were able to break out of the Malthusian Trap and since then human population has grown exponentially. Now some of the major issues the human population is facing is disturbing the natural balance of the environment by having to turn more land into agriculture to feed a growing population. This loss of nature is causing a devastating amount of biodiversity loss throughout the planet. As new technologies emerge to try and solve these issues they must

The results show that Manuel Antonio has the highest Simpson’s Index of Diversity with a .92. I believe that these results are miss leading. The Simpson’s Index of Diversity takes into account both species richness and evenness. Richness is defined as “the number of species per sample” and evenness is defined as “a measure of the relative abundance of the different species making up the richness of an area” (Country Side Info). Manuel Antonio was very even, all of the plant species in the area had one or two individuals. The other samples that I took all had at least one species that was much more prevalent than the others. Due to evenness being a main factor in the Simpson’s Diversity of Index is why according to this formula Manuel Antonio
