This document discusses the debate around animal experimentation. It notes that while some believe experiments can benefit medical research, others argue it causes animal pain, distress and death. The costs and benefits are weighed differently by scientists on both sides of the issue. Specific examples are given of drugs that passed animal tests but later harmed humans, questioning how predictive such tests are. The debate revolves around balancing scientific progress with animal welfare and ethics.

1. Essay on Animal Rights
For the past 20 years, there has a been an on going heated debate on whether experiments on
animals for the benefit of medical and scientific research is ethical. Whether it is or isn't, most
people believe that some form of cost–benefit test should be performed to determine if the action is
right. The costs include: animal pain, distress and death where the benefits include the collection of
new knowledge or the development of new medical therapies for humans. Looking into these
different aspects of the experimentation, there is a large gap for argument between the different
scientists' views. In the next few paragraphs, both sides of the argument will be expressed by the
supporters.

The stress of handling, confinement and isolation alters the animal's mental stability and introduces
yet another experimental variable that makes any results from testing even less valuable to human
helping. In many cases, drugs and other substances are given to the test animals but studies have
shown considerable differences in the effects of these drugs on different species.
David Salsburg of Pfizer Central Research has noted that of 19 chemicals known to cause cancer in
humans when ingested, only seven caused cancer in mice and rats using the standards set by the
National Cancer Institute. This justifies that many substances that appeared safe in animal studies
and received approval from the U.S. Food and Drug Administration for use in humans later proved
dangerous to people. The drug milrinone, which raises cardiac output, increased survival of rats
with artificially induced heart failure; humans with severe chronic heart failure taking this drug had
a 30 percent increase in fatalities. Also, the antiviral drug fialuridine seemed safe in animal trials yet
caused liver failure in seven of 15 humans taking the drug (five of these patients died as a result of
the medication, and the other two received liver transplants). Scientists and the populous that do not
agree with

2. Essay on Zoos and Animal Rights
Among many other fun and exciting attraction to visit around our community, a visit to the zoo has
always been a memorable experience. This cost effective priceless lifetime experience is being
undermined by a group of activists all around the country. People for the Ethical Treatment of
Animals (PETA), world largest animal rights organization, argue that zoos deprived animals from
satisfying their most basic needs. They urge not to patronized zoos and claims that the money spent
on ticket purchases pays for animals to be imprisoned and traded, not rescued and rehabilitated. They
go on saying in summary that zoos strip animals from their rights. So this heated debate revolves
around the animal rights and how the zoo industry inhibits it....show more content...
Fifty–four percent of the individuals surveyed offered comments about the elevated awareness of
their role in conservation as a direct consequence of their visit to the zoo. Furthermore, sixty one
percent of visitors were able to talk about what they learned from their previous visit, and thirty five
percent reported that the visit reinforced their existing beliefs about conservation, stewardship and
love of animals in different surveys. As news writer Amy miller (2014) states zoos are working
harder than ever to save endangered animals around the world. She explained that the Wildlife
Conservation Society (WCS), which is headquartered at the Bronx Zoo in New York City, is
working with local officials in Malaysia to stop people from hunting exotic birds to sell their
feathers. Furthermore, The California zoo is famous for its work helping to save China's giant panda.
Three panda cubs have been born at the zoo already. The San Diego Zoo now has the largest
population of giant pandas outside mainland China.
In addition to promoting conservation many modern zoo encourage research. Studies and research
have to be done in order to contribute to the preservation of endangered species. The San Diego zoo
for instance just opened the Conservation and Research for Endangered Species Center. The $22
million center gives scientists cutting–edge instruments and plenty of room to do their work as
mentioned by Amy (2014). Farmers in Africa think the spotted cheetah is an

3. Essay on ANIMAL RIGHTS
Animals have their own rights as do to humans and we should respect that and give them the same
respect we give each other. Animals deserve to be given those same basic rights as humans. All
humans are considered equal and ethical principles and legal statutes should protect the rights of
animals to live according to their own nature and remain free from exploitation. This paper is going
to argue that animals deserve to have the same rights as humans and therefore, we don't have the
right to kill or harm them in any way. The premises are the following: animals are living things thus
they are valuable sentient beings, animals have feeling just like humans, and animals feel pain
therefore animal suffering is wrong. 2 sources I will be using...show more content...
Singer wants to show that everyone's interest or good counts for one (Singer 8). Singer deals with
the question of suffering as his main point since his goal is to show that rights are based on the
capacity for suffering. He supports with some fundamental facts that these animals have nervous
systems just like ours, which "respond physiologically as ours do when the animal is in
circumstances in which we would feel pain" (11). Singer's arguments can be supported by Jeremy
Bentham, the founder of the reforming utilitarian school of moral philosophy, who incorporated the
essential basis of moral equality into his system of ethics by mean of the formula: "Each to count for
one and none for more than one." In other words, the interests of every being affected by an action
are to be taken into account and given the same weight as the like interests of any other being
(Singer 5). Singer argues that we do not have good legal reasons, scientific or philosophical, for
denying that animals feel pain. Therefore, he deems that "if we do not doubt that other humans feel
pain we should not doubt that other animals do so too" (15). He proves that animals can undergo
pain and that there can be "no moral justification for regarding the pain (or pleasure) that animals
feel as less importance than the same amount of pain felt by humans" (15). This portrays the rights
and equality the animals may possess comparison to
