Zach Du, Chapter 13, Question 6

The part which talks about Geography's effects on economy really caught my attention: "Given the varied political, economic, and social histories of regions around the world, it must be more than coincidence that almost all of the tropics remain underdeveloped at the start of the twenty-first century" (303). Development expert Jeffery Sachs gives us the answer of why these tropical weather has negative effects on economy: in the tropical areas, where always has high temperature and heavy rainfall, food production is much less efficient than European countries and it's much easier for diseases to spread all around the town; on the other hand, Chicago for example, would have much lower possibility to suffer diseases, because its cold weather could control mosquitoes, therefore reduce the spread of any bacteria.
