II. Human Activities Face limitations｜ The finite nature of resources	II. 限界に直面する人間の営み｜資源の有限性
The energy and mineral resources humankind consume are finite and how we utilize these valuable resources is a major challenge for us. If human activities continue as they are of today, many resources will be depleted within 100 years.	人類が消費しているエネルギー資源や鉱物資源は有限であり、これらの貴重な資源をどのように活用するかは、人類の大きな課題である。人類がこのまま活動を続けると多くの資源が100 年以内に枯渇する。
