II. Human Activities Face limitations｜ Explosive population increase	II. 限界に直面する人間の営み｜人口爆発
Changes in the ratio of urban population to world population imply that urbanization is one of the major global environmental problem humankind is facing. In particular, the increase in urban population is significant in the developing regions. This trend is more conspicuous in Asia.	世界の人口に対する都市人口割合の推移から、人類にとって、都市化が地球環境問題の大きな課題の一つであることが読み取れる。中でも発展途上地域で都市人口が増加しており、アジアでこの傾向は顕著である。
