I surveyed open sources mainly of prefectural plans about coastal debris and biodiversity to compare them. Entities related to marine biodiversity widely overlaps those to coastal debris. However, museums feature the former, while tourist and marine-leisure industries and fishery cooperatives feature the latter. Some maritime prefectures do not refer to coastal debris in their prefectural plans on biodiversity. Problems on coastal debris vary intensively among prefectures. It is not proper to conclude “Small ratio of artificial to natural coastal debris makes no problem.”

  The aim of the present paper is to reveal that there exist five “fallacies of composition” in Kalecki’s principle of effective demand that establishes “the fundamental prerequisites to macroeconomics,” which demonstrate that investments determine savings and that savings are equalized by investments in relation to income. It is the five “fallacies of composition” that are to be found in his theories of investment. Concerning the fundamental prerequisites, the first fallacy of composition deals with financing investment, the second one is discovered in his theory of multiplier, and the third one, which is identified by Kalecki himself, is involved in investment expenditure. The fourth fallacy of composition is turned up in investment decisions that are an increasing function of gross profitability as the product of the gross profit margin and the degree of utilization of capital equipment. The fifth one is searched out in the degree of utilization of capital equipment in relation to investment decisions, which reflects the level of production and then influences on the level of employment. It is the fallacy of composition that makes it possible to analyze macroeconomy, which, however, is not simply identified with the sum of individual agents, so that provides raison d'être for macroeconomics and shows the significance of holism in contrast to reductionism from methodological individualism.

  The National Institute of Infectious Diseases mentions that the abandoned plastic sheeting of water can be a source of mosquitoes. In the Republic of Panama, AAUD has not been collected the all plastic containers and packaging waste. The mosquito is outbreak at resulting waste. The plastic containers and packaging have 2 types that is film and container. The container can hold water in physical. However, the wettability of the poly waste film’s surface has not been studied ever. Therefore, we analyzed for material and contact angle of the 13 of waste plastic containers and packing which were being abandoned in Panama City. As a result, abandoned waste had a single material or composite material, and the contact angle was less than 40 degrees. It means that the abandoned plastic container and packaging wastes were hydrophilic. Hydrophilic properties make it susceptible to rainwater. The collection of abandoned waste contributes to mosquito control.
