The discussion topic this week that interested me the most was how technology and dependence on other areas can sometimes do more harm than good. This was explained really well in Chapter 3 of Collapse when Diamond discussed the Polynesian Islands of Mangareva, Pitcairn, and Henderson. Diamond described how each island had its own unique thing that made it important, and what would eventually establish it in a trade group between the three islands. Mangareva was capable of having a large population with a heavy resource of basalt and the black-lipped pearl oysters, both of which were good for making tools. Mangareva lacked quality stone on its island which is a reason as to why they started to trade with the other islands, specifically Pitcairn, who had an abundance of stone as well as large trees that could be used to make canoes (furthering the trade between the islands). Pitcairn was a tiny island, only capable of sustaining ~100 people, so it traded with the other islands as well, including Henderson. Henderson Island was the largest island and thus had the space to have an abundance of crops as well as being able to sustain a good sized population. Trade between these three islands became the norm and eventually the islands found themselves relying on each other for a bulk of what they needed to live. Due to its high latitude, Mangareva eventually fell due to deforestation. The collapse of Mangareva was detrimental to not only its inhabitants but to the people of the other two islands as well. Pitcairn and Henderson depended heavily on trade between their two islands but between Mangareva. Trade essentially ceased between the other two islands once Mangareva collapsed due to the heavy dependence between all three. Once trade stopped, the other two islands managed to collapse as well, with erosion being a major problem on Henderson and Pitcairn’s lack of sustainable land being its problem. The fall of Mangareva and the subsequent collapses of Henderson and Pitcairn can be directly related to the negative impacts of technology growth as well as increasing dependence, or what could be looked at as a start of globalization. These islands relied too heavily on their technology growth instead of learning how to live a sustainable life on each of their islands. The stories of these islands can be somewhat of a negative metaphor for today since the world is becoming increasingly more globalized as the days go by. Diamond brought this point up in Chapter 3 saying these “examples of collapses triggered by the breakdown of an environmentally damaged trade partner [are a] preview of risks already developing today in association with modern globalization” (page 121). Diamond is essentially discussing that the world could possibly be too dependent on each other and that, much like with these ancient collapses, if one major link in the chain of globalized trading were to fall, then perhaps other major nations involved would fall too. This can somewhat be compared to the domino theory that was often discussed in politics during the cold war, meaning that if one nation were to fall (due to environmental degradation rather than to communism) then others would immediately follow suit. I’m not too sure if this would be an immediate collapse but there is definitely something to be said about how dependent most countries have become on others in regards to trade. It will be interesting to see if globalization becomes an even bigger phenomenon in the future or if people will attempt to be able to live sustainable lives, ones that would attempt to rely less on outside resources.

This can contribute to “McDonaldization” or the ever growing presence of American Corporations in foreign countries, an offset of the more common globalization.
