2. Demand for raw materials continues to increase with population growth, economic prosperity and globalisation; it is expected to grow fourfold in the coming 40 years. Without international agreements, global commons are under serious threat.
With increasing global pressure on natural resources, current patterns of resource use are not an option. Solutions such as recycling and more efficient use of resources only go part of the way in curbing the growing demand for raw materials. Changes will need to be made in production and consumption patterns, and technological breakthroughs are needed to enable this.
