In broad terms, these circumstances involve growing markets in certain classes of goods and services (natural-resource intensive products), concomitant with absent markets and collective policies for natural capital (ecosystem services). As global environmental problems frequently create additional stresses on the local resource bases of the world’s poorest people, GNP growth in rich countries can fuel downward pressure on the wealth of the poor.
从广义上讲，这些情况包括某些门类商品和服务（自然资源密集型产品）的增长型市场伴随着相关的市场政策和对自然资本（生态系统服务）的收帐政策的缺失。随着全球环境问题频繁地给世界穷国的本地资源基础造成额外的压力，富国的GNP增长也可能会对穷国的财富造成更大的压力。
