Today's Robots, Japan

Japan has nine forest ecoregions which reflect the climate and geography of the islands. They range from subtropical moist broadleaf forests in the Ryūkyū and Bonin islands, to temperate broadleaf and mixed forests in the mild climate regions of the main islands, to temperate coniferous forests in the cold, winter portions of the northern islands.
Environment
In the period of rapid economic growth after World War II, environmental policies were downplayed by the government and industrial corporations. As an inevitable consequence, environmental pollution occurred in the 1950s and 1960s. Responding to rising concern over the problem, the government introduced several environmental protection laws in 1970. The oil crisis in 1973 also encouraged the efficient use of energy due to Japan's lack of natural resources. Current priority environmental issues include urban air pollution (NOx, suspended particulate matter, toxics), waste management, water eutrophication, nature conservation, climate change, chemical management and international co-operation for environmental conservation.
