Diary-4- What I thought in the US no.2. This is my forth entry. Thanks for visiting and reading my diary. I would like to begin where I left off last time. You can find the last entry on my italki page if you are interested in. I am welcome to collection from you! (3) Land and population Area of the US is very big: Actual area of the US is 9,629,091 km2 which is approximately 25-folds bigger than Japan’s area (377,972 km2). I was very surprised when I knew that just one state (e.g. Texas which is 696,241 km2) is larger than Japan. It’s crazy big. Indeed, we have never seen horizon in Japan. In the US, however, I can see horizon everywhere and I re-recognized the origins of name of the US. By the way, when I wrote this entry, I found that horizon means a line between earth and sky. In other words, English don’t distinguish between a line that separate land and sky from a line that separate ocean and sky. Since I had curiosity, I asked my co-worker who is native English speaker, about this and he said we don’t distinguish land and ocean because land and ocean are both a part of earth. This was also surprising for me because Japanese have each word corresponding to them which are called ‘ちへいせん (a line between land and sky)’ and ‘すいへいせん (a line between ocean and sky)’. I’m curious to know whether other language have each word. Next, let’s look at population of the US. Current population of the US is 300 million which is just only 3-folds larger than Japan’s population (100 million), meaning that The US is very low population density. I’m wondering that such huge land probably provides excess amount of source such as food, natural energy and something like that but why the US population is not get increase. Today’s topic is too difficult for me to write in English! If you can correct my English, that would be great! If not, no worries. Thanks in advance!
