Pros & Cons


-Larger animals to produce more products such as wool, meat, etc.

-transgenic animals create insulin which is a synthetic that can help treat diabetes

-can benefit in new experimentation discoveries


-scientists don't always know the side affects or consequences, may kill animals if experiments fail

-trans-genesis does not bring any good to animals

-the products that are made from the transgenic animals may be at risk for harming humans

News Article Summary

Animal use in laboratories have increased by almost 73 percent in the last 15 years.

That was driven by an increase in rodent use. On October 31, 1997 there were 19,298 in inventory. On December 17, 2002, there were 12,1731 in inventory. Then on November 30, 2007, there were 20,601 animals in inventory. So Since 1997, there has been 1,303 more animal in inventory. However, it did decrease between 1997 and 2002. Since then the trend may have changed. Rodents are convenient for laboratory use. They are a feasible research tool. PETA, an organization that does not want animals to be in use for research at all, has declined to share data behind the study. That was an unusual decision
