Why does animal testing still exist?
Companies test on animals to provide data that they can use to defend themselves when they are sued by injured consumers—even though some courts have ruled that the FDA has failed to show that the results of animal tests can be extrapolated to humans.
What percentage of animal testing is successful?
In 2004, the FDA estimated that 92 percent of drugs that pass preclinical tests, including “pivotal” animal tests, fail to proceed to the market. More recent analysis suggests that, despite efforts to improve the predictability of animal testing, the failure rate has actually increased and is now closer to 96 percent.
Why we should stop testing on animals?
The harm that is committed against animals should not be minimized because they are not considered to be “human.” In conclusion, animal testing should be eliminated because it violates animals’ rights, it causes pain and suffering to the experimental animals, and other means of testing product toxicity are available.
Did methane kill the dinosaurs?
In an article published in the September issue of Geology, Gregory Ryskin, associate professor of chemical engineering, suggests that huge combustible clouds produced by methane gas trapped in stagnant bodies of water and suddenly released could have killed off the majority of marine life and land animals and plants at …
Did dinosaurs produce methane?
Dinosaurs may have helped warm ancient Earth via their own natural gaseous emissions, a new study says. Like modern-day ruminants, giant plant-eating dinosaurs likely had microbes in their guts that gave off large amounts of methane—a potent greenhouse gas even more effective at trapping heat than carbon dioxide.
What killed the dinosaurs?
For decades, the prevailing theory about the extinction of the dinosaurs was that an asteroid from the belt between Mars and Jupiter slammed into the planet, causing cataclysmic devastation that wiped out most life on the planet.
