Chemical lawn treatments and weed killers, pest control pellets and sprays, and items we use to spruce up our landscaping can all be a source of dangerous toxins for pets. Even some garden flowers and plants can be highly toxic to our canine and feline friends.
On the one hand, there are clear ethical arguments against animal experimentation. To use a common example of this practice, laboratory mice may be given an illness so that the effectiveness of a new drug can be measured. Opponents of such research argue that humans have no right to subject animals to this kind of trauma, and that the lives of all creatures should be respected. They believe that the benefits to humans do not justify the suffering caused, and that scientists should use alternative methods of research.
It is estimated that more than 665 million animals worldwide are used in laboratory experiments every year. But because only a small proportion of countries collect and publish data concerning animal use for testing and research, the precise number is unknown. For example, in the United States, up to 95 percent of the animals used in laboratories (purpose-bred rats, mice and birds, fish, amphibians, reptiles and invertebrates) are excluded from the official statistics, meaning that figures published by the . Department of Agriculture are no doubt a substantial underestimate.
This short-term therapy option for patients with severe heart failure produced severe and sometimes fatal thrombocytopenia (decreased blood clotting ability) in humans, despite no evidence of this effect in 7-year-long animal tests. Only after approval, and only in marmosets and a very specific, metabolically compromised strain of rat, were similar effects found. 7
However,animal experiments also have some objectionable is cruel to see animal undergo painful suffering or many animal-support activists object to the experiments as a way to test the safety and effectiveness of the huge database of knowledge and modern computer models,animal testing are also point out many animal tests are ineffective ,many drugs should be withdrawn from the market despite extensive particularly think that animal testing should note be used for non-essential products such as cosmetics and shampoos.
One of our most relied-upon pain relievers, Aspirin (Acetylsalicylic acid), causes teratogenic malformations in mice, rats, dogs, cats, rabbits, and monkeys. 8
Smoking cigarettes and eating lots of cholesterol were given the thumbs-up by animal experimentation. Probably no two mistakes have cost as many lives. Now millions of women on hormone replacement therapy are at twice the risk of breast cancer and heart disease, thanks to tests in monkeys which predicted the opposite. How many more people have to die before we admit there is a problem with animal testing?
Are used in a variety of conditions, ranging from brain tumors to skin diseases. They have been shown to cause cancer in some rodents, despite their being used safely by humans for years.
Many scientists believe that in vitro testing is scientifically superior to the savage testing on animals. The same is true for radiation exposure tests and cosmetic testing. Technology such as MRI, EEG, PET, and CT scans provide alternatives to cutting into the brains of cats and monkeys. Cancer antibody testing is better conducted with human cells than by injecting mice with cancer. Many medical schools are eliminating animal testing because of its unreliability.
With arguments to be made on all sides of the issue, we invited a panel of leading experts with diverse viewpoints to share their thoughts. We asked them one simple question – should testing on animals be banned? – and received 75 Yes votes, 7 Nos and 7 Maybes. You can check out the experts bios and comments below. And if you have an opinion on the topic of animal testing, make sure to share it in the Comments section.
Use of this drug for treating heart failure led to 75% of patients developing thrombocytopenia (lack of blood cells needed for clotting), despite a comprehensive program of animal studies in mice, rats, hamsters, guinea pigs, dogs and rhesus monkeys. Some of these [human] patients died.
This synthetic oestrogen was designed to prevent miscarriage, but it did just the opposite by increasing the rate of spontaneous abortions, premature births and neo-natal deaths. No human trials were done all the safety data was collected from animals.
Nowadays animal experiments are widely used to develop new medicines and to test the safety of other products. Some people argue that their experiments should be banned because it is morally wrong to cause animals to suffer, while others are in favor of them because of their benefits to humanity. Discuss both views and give your own opinion.
Biological differences between and within species require scientists to proceed with caution when interpreting the results of any experiment. Animals of different ages, sexes, developmental stages, and of different health status can all respond differently to experimental treatments. It is no surprise, then, that humans respond differently to administered pharmaceuticals than other animals. The surprise comes when scientists, physicians, and regulatory officials are willing to risk the health of patients by relying on animal experiments to predict the effects of drugs in humans—sometimes with grave results.
Health research aims to discover the causes of human illnesses and to prevent or treat them, but the benefits of today&rsquo s health research are becoming harder to see. Failure of animal models
