Because of the circulation of zoonotic agents between animals, humans, and the environment, the cost of a disease affects human activity and health in addition to other economic sectors.
Large snow accumulations in roof steps or beside buildings may affect human activities or lead to structural damage.
Since intensities and routes of typhoons affect human activities in Asia, it is important to examine the long-term behavior of typhoons over East Asia.
On the other hand, flood events that affected human activities were compiled by the staff of a local museum (Jomon Museum) (Mikata Town History 1990; Memoric magazine of 50th anniversary of Kaminaka-Town organization and Center of Kaminaka-Town residents 2004; Looking back the history of Mikata-Town and Mikata-Town 2005).
This is, however, far from sufficient in view of the important role of insects in diverse ecosystems, great number of insect species affecting human activities as pests or vectors of diseases, and need for sequence data for studies on processes such as insect evolution, ecology, behavior, insecticide resistance, development, and physiology.
As described in the introduction, ash fall can seriously affect human activity.
Space weather covers the study of the conditions in space that could affect human activity.
Phenomena originating in the Sun that can affect human activity include explosive events such as flares and coronal mass ejections.
Over the last decade, a vibrant international community has grown up around the study of space weather, focusing on the study of how varying conditions in geospace affect human activity (e.g. Baker 1998, 2002; Echer et al. 2005; Bothmer and Daglis 2007).
It can be assumed that climate variables also affect human activity and, subsequently, human contact with rodent excreta changes.
