Add to ORKGHow should we consider the balance between natural ecosystems and human survival? In order to make this question the learner’s own, we have shown 2 examples of teaching materials that can be practiced in integrated learning at school. One is learning using public data. It is a suggestion to education that illnesses and suicide rates that seem to be unrelated to the weather may change due to the ongoing climate change. The other is learning about the cases of epidemic prevention and disaster prevention, atomic bomb disaster at Hiroshima, area between natural and man-made disasters, local disaster prevention, based on the materials at that time, and suggestions for education.departmental bulletin pape
