Answer 3

The transcontinental railroad resulted in many environmental changes, largely because it resulted in a huge influx of new people all the way across the continent. It marked the end of the American Native civilizations as they knew it and brought in the farmers to clear the land and establish permanent residences on the land.

The gold rush (all of them) had devastating effects on the enviroment because they drew in the worst kind of people who were interested in getting rich and moving on. They didn't come to establish a home and hade no regard for the scars they left on the land. They cut the timber, polluted the streams, anything to get at the gold, and then moved on.

Answer 4

Air pollution.  People shot buffalo from the windows.  Development of towns along the tracks and their associated pollution.  Cheaper rail service encouraged beef cattle production and the cattle ate away the prarie.

The gold rush people ate just about all the large mammals that were left after the trappers were through.
