Notes on Migrants and other things

   Today we were given another worksheet to take notes on. Transportation improvements have diminished the importance of environmental obstacles the block migration. Today the major obstacle a migrant faces is politics. The U.N. classifies countries by four types of immigration policies, the first is maintaining the current level of immigration, the second is increasing the level, the third decreased the level, and the fourth has no policy. The number of people allowed to immigrate to the U.S. is the most its ever been, but the amount of people want to come is greater.
