What is the most effective way for a ruler to maintain order.

The most effective way a ruler to maintain order is to listen to the people of the country/empire their ruling. If the ruler doesn't listen to the people they might revolt and that would not turn out good. In the face of history if the people revolt it won't look very good in the future when people teach the history of your empire/country.

I agree with Jared Diamond's thesis. I agree with it because i too believe in geographical luck. geographical luck is very important. having a good geographical area for you civilization is important because in order to have a good civilization you need a good climate, available food, and you need to be near a water source.

1. Advantages and Disadvantages of Farming

In my opinion the advantages of agriculture and farming outweigh the disadvantages. It does because without farming how would we have food? I mean i guess we could go out and search for our food, but in our society, where almost everyone has a full time job, no one has the time. Plus in the city there is not enough space so we have to rely on the farmers for our food. We could could lessen the negative effects of global warming by buying food from local farms, instead of buying from farms across the country.
