Entities Related to Coastal Debris and Biodiversity

Abstract

  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.”
