Each   additional   century   of  European colonization is associated with  a 40 percent boost in income today and a  reduction in infant mortality of 2.6 deaths  per 1,000 births. First Three- Tropical. (24% of the World  Population Lives here,  40% of average  income) Next - Subtropical Second Group - Temperate. High  Incomes (Twice the world average, 35%  of world population). The first is the temperate drift hypothesis,. emphasizing the temperate (or away from the equator) shift in the center of economic gravity over time. According to this view, geography becomes important when it interacts with the presence of certain technologies. For example, one can argue that tropical areas provided the best environment for early civilizations. after all,humans evolved in the tropics, and the required calorie intake is lower in warmer areas. But with the arrival of appropriate technologies, temperate areas became more productive. The technologies that were crucial for progress in temperate areas include the heavy plow, systems of crop rotation, domesticated animals such as cattle and sheep, and some of the high productivity European crops, including wheat and barley. Despite the key role of these technologies for temperate areas, they have had much less of an effect on tropical zones also implies this view in his recent paper when he adapts Diamond.s argument about the geography of technological diffusion. Since technologies in the critical areas of agriculture, health, and related areas could diffuse within ecological zones, but not across ecological zones, economic development spread through the temperate zones but not through the tropical regions argues that areas in the tropics had an early advantage, but later agricultural technologies, such as the heavy plow, crop rotation systems, domesticated animals, and high- yield crops, have favored countries in the temperate areas o b) Disease Tropical Climate allows a bad health environment since. It allows more parasites to evolve. Also these are the regions which have inhabited by humans for many more years and thus the parasites had time to evolve to live off humans in temperate zones, humans have lived only for about ten thousand years, and thus the parasites have not had time to evolve. Malaria Ecology Index- a measure of how easy it is for malaria to spread given the geographical nature.(a function of temperature and rainfall). For some countries such as India- close to Spain and thus should be able to get rid of Malaria. **Mauritius small island that cleaned out its swamps and spraying DDT. c) Cold Climate and Hard Work People in warm climates cannot work because their bodies overheat. Most work translates into body heat. Sweat evaporates to keep the body cool. In hot and humid climates, sweat does not evaporate.
