What I learned on the 24th

On Saturday the twenty-fourth, in class, I was surprised that it is common among species to go extinct after a certain amount of time. I know that species can live for a shorter amount of time if their environment changes dramatically. The Siberian Tiger is one species that went extinct due to humans changing their environment. Russians contributed to the disappearance of them by poaching, while people were building roads and logging. This pushed the species away to extinction.
I never realized that humans had such an affect on the environment in the past. People did not have the technology we have today; however, were still successful in making mammals from Africa and Australia extinct.
In the last half hour of class I was very interested about learning how and why people moved into cites and why they spread. I also found it fascinating that there are different types of land development. I am very interested in what is to be said for the rest of the chapter in next class.
