Symposium on Alien Species Threats

Three Crises to Biological Diversity in Japan 
The 1st crisis: Wild life is threatened with extinction due to the indiscriminate or excess hunting.
The 2nd crisis: Abandonment of traditional practices in Satoyama and farming lands. Village farms are left unkept.
The 3rd crisis: Invasions of exotic species, newly introduced species, and chemicals that didn’t exist before in nature.

However, it has been disrupted by the expansion of invasive alien species, and the damage caused to the ecosystem and the agriculture, forestry and fisheries industry, has reached to the threatened level. Such a problem is called "The Third Biodiversity Crisis" officially as defined by the Ministry of the Environment.
