Animal Testing

Have you ever considered fact that every year millions of animals undergo painful death as result of scientific research? Because while most people think animal testing is necessary, others are upset by what they see as needless suffering. This essay outlines some of the arguments for and against animal testing.
First, let’s look at the arguments. One very positive point is that many medical treatments and procedures have been developed from such experiments. Since animal share many features with humans, scientists use animals to test the safety and effectiveness of newly developed drugs. Moreover, there is a large supply of animals. Some, such as mice and rats, have many babies, and there is no danger of extinction for these species. Finally, some advocates think that animals are less valuable than people. If there is a mistake, it will not cost a human life.
However, there are also a number of arguments against animal testing. Perhaps the most important point is that animals may be suffering unnecessarily. Critics do not believe that every new drug needs to be tested on animals. Furthermore, some feel animal testing is ineffective; they point out that many drugs still have to be withdrawn from the market despite extensive testing. Last, some campaigners would like to see alternative used. They feel more human testing is possible and, too, that we could rely more on organ donors.
To conclude, we need to ensure that animals used for experimental purpose do not suffer much pain. Although some animal testing may be unavoidable at present, treating our fellow creatures mercifully will demonstrate our humanity.

The table shows the number of miles travelled in Wales, including type of walking, bicycles, cars, local buss, coach, trains and taxis in 1990 and 2005.

First walking and bicycles slightly increased from 1990 and 2005, it changed from 255 to 258 for walking and 51 to 52 for bicycles. Coach, trains and taxis increased from 54, 289 and 13 to 124, 366 and 42 respectively. The biggest increased happened for cars; it changed from 3199 to 4806 in 2005. The special case happened for local bus, it decreased from 429000 to 274000 in 2005. And maybe it decreased because the number of cars and taxis was increased.

Over all, all models increased in total, and it increased from 4740 to 6475 in 2005.
