Article: Sex, Drugs, Disasters and the Extinction of Dinosaurs

Dinosaurs were appeared in the millions years ago, and prosperity in the end of the Mesozoie reptiles. The main reasons cause dinosaurs extincted are sex, drugs and disasters. First of all, the temperature suddenly dropped sharply, resulting in lived in the warm shallow sea, land and many kinds of dinosaurs quickly perish the marsh. "Cold-blooded animals lacking a physiological mechanism for keeping their temperatures constant."(Park25) Because of temperatures decreased, hatched is female or make offspring. The gender is not smooth, inevitably leads to the dinosaurs. The second reason is drug. During that period, Earth gymnosperms disappearing, replaced by a large number of angiosperms, these plants contains no toxin in gymnosperm, form a huge dinosaur eat far, intake of angiosperm cause body endotoxin accumulation is overmuch, was finally killed. Carnivorous animals eat the meat from the toxic after was also killed. The third idea is disasters. At the time of bacteria is in the midst of the extinction of dinosaurs, he think is likely to be a plague bacteria caused these huge the disappearance of the dinosaurs. Disease popular led to the destruction of the dinosaurs, the reason is that the dinosaurs do not have the immune system and reproductive is very slow. Parasites to the spread of the virus to a dinosaur, lead to their extinction, mammals from the same period, however, survive the reason is that they are not affected by disease.

The author uses the emotional tone describe the reasons how dinosaurs became extincted. He said " My greatest unhappiness with most popular presentations of science concerns their failure to separate fascinating claims from the methods that scientists use to establish the facts of nature. The author atated that the scients express the information using the boring way. It is hard to catch their attention for science. He suggests that people should show the information in a way that can arouse people's interest or controversy about it. It will make more people pay attention on science. Otherwise, people will not be able to understand the information. The connection is important.

I agree with the author that most people does not familier and not interested in science. Although science article is really interesting to read but a it is hard to read with two much academic vocabularies and make people does not want to finish reading it.
