Chimera. The word originally comes from that of Greek mythology and describes an animal that is a combination of a lion, a serpent, and a goat (Sherringham, 2008). Sherringham (2008) describes the present-day definition of how it relates to science and research as organisms “comprised of at least two genetically distinct populations of cells originating from independent embryos,” but the combined genetics are not a result of sexual reproduction (Sherringham, 2008, p. 767). The word chimera can also be used to refer “to a biological entity composed of genetic material from members of two distinct species” (Eberl & Ballard, 2009, p. 471).

- ... Currently, the United States and the United Kingdom do not have laws regarding the use and research of chimeras .Only the states of Louisiana and Arizona have laws regarding human and animal hybrids (Silverman). Cynthia Cohen, a member of Canada’s Stem Cell Oversight Committee, believes the U.S. should have implement a law against the transferring of human cells into animal embryos and vice-versa. However, Weissman is against the ban and claims that can hinder the research, that can save thousands of lives (Mott).... [tags: medical, genome, dna, embryo]

- Overview The current issue facing societies around the world is human-animal hybrids experiments. These experiments are viewed in two lights, positive and negative. The positive of having these tests are that scientists could rid the world of diseases. However on the other hand people see these studies as inhumane and detrimental to everyone’s well being. This paper will be broken down into 6 areas including (1) a brief history of hybrid experiments dating within the decade, (2) a view of the stakeholders in the issue at hand, (3) how people would interact with humans receiving these treatments, (4) cultural and ethical considerations, (5) problems still at hand, and (6) a conclusion....

- ... One of the best examples I found of animal rights is that “the prophet taught that the animals’ rights are to be respected, to be spared from suffering and given the food it needed, to be treated well, was not negotiable.” (Waldau 2010, 3) This shows what I believe to be the best interpretation of what animal rights exactly are. I choose to explain animal welfare only because upon researching I found a lot of information I thought pertained to animal rights actually was related to animal welfare....

- ... On the hand, many animals do well in captivity, especially in home setting. Arguably the most controversial part of the human-animal relationship is animal testing. Animal testing can vary in extremity. There are very harsh tests and there are tests that are minimally invasive. The biggest controversy over animal testing is that, although it can result in new products and medical treatments, it can be torture for animals. Potential for medical advances is something that many people believe is worth the sacrifice of animal wellbeing.... [tags: Animal rights, Animal welfare]

- Are Animal Lives as Important as Human lives. The question of whether or not the lives of animals are equivalent to lives of humans remains open. Facts show the many differences between human and animal life, and that very people would argue that the lives of animals aren’t valued. It’s known that humans may be more intelligent than animals and we may have more influence over the Earth however, that doesn’t determine importance. Therefore, human lives are not more important than animal lives. Animals have their part in the environment and do make a contribution to Earth....

- When it comes to the topic of animal cruelty, most of us will agree that animal testing has improved the quality of human life. Where this agreement usually ends, however, is on the question of whether or not there are alternative methods available to researchers. Whereas some are convinced that animal experiments don’t always predict human outcomes, others maintain that there are no alternatives to animal testing. My own view is that animal experimentation is necessary. Carl Cohen, who is a professor of philosophy at the University of Michigan, remembers when he was a counselor at a camp in North Carolina for young children in 1948....

With all that being said, Regan says it is inadequate mainly because it does not put animal welfare as the top priority, but rather explains the issues involving the people conducting the cruel act. The final account that Regan talks about is the Utilitarian account. The Utilitarian account states that having consequences for everyone and everything explains how we should treat animals. Regan claims the utilitarian account is inadequate, due to the reason it could promote radical differential treatment and injustice, however he says that out of the three accounts he talks about, this one is the most plausible along with the least prejudicial....

- Currently, I am a senior at the University of Nebraska at Omaha pursuing a dual major in Neuroscience and Psychology. I have always been interested in human-animal interactions from multiple perspectives including the psychological, sociological, personal and ethical perspectives. From a psychological perspective, I have studied the importance of animal-assisted therapies in various clinical disorders such as post-traumatic stress disorder (PTSD). I have also studied human-animal interaction in the context of violent offenders and the associated cases of animal abuse.... [tags: human animal behavior, pavlov, skinner]

- 1 Introduction A healthy and prosperous society is based on a healthy and prosperous economy. And during the last century, following the economic growth, the social networks expansion and the geographic dispersion of economic activities, transport became the spinal column of commercial and industrial interaction. The capacity of individuals as well as firms to exchange goods and services became crucial not only for economic purposes but also for better life quality. Unfortunately, the drawback effects of transport have an important impact on the natural and human environments on one hand, and on the growing fuel consumption accompanying the current oil crisis on another hand....

- Field Experience Report Hybrid Cars The world population is increasing at a massive rate and with the increase in population growth more space is needed for building houses, roads, schools, hospitals, etc. “The world's population will rise from 6.5 billion to 9.1 billion by 2050, according to a United Nations survey released Thursday. Much of the growth will take place in the least-developed countries, where a high rate of mortality is outweighed by an even higher rate of fertility. Their current collective population of 800 million is projected to swell to 1.7 billion in 2050.” (Wald) Human population growth can be seen as having a major impact on the environment as human activities are i...
