| degradation of natural resources The result of the cumulative activities of farmers, households, and industries, all trying to improve their socio-economic well being. These activities tend to be counterproductive for several reasons. People may not completely understand the long-term consequences of their activities on the natural resource base. The most important ways in which human activity is interfering with the global ecosystem are: 1. fossil fuel burning which may double the atmospheric carbon dioxide concentration by the middle of the next century, as well as further increasing the emissions of sulphur and nitrogen very significantly; 2. expanding agriculture and forestry and the associated use of fertilizers (nitrogen and phosphorous) are significantly altering the natural circulation of these nutrients; 3. increased exploitation of the freshwater system both for irrigation in agriculture and industry and for waste disposal | 自然资源恶化 (农民、家庭和产业界为了增加其社会经济利益的各种活动所累积的效应。 许多原因使得这些活动导致不良的后果。 人们可能尚不完全明了这些活动对自然资源基础的长期影响。 人类活动干扰地球生态系统的最重要影响方式有：1.石化燃料燃烧可能在下一世纪中期使大气中二氧化碳浓度加倍，且硫和氮排放也将持续大幅增加；b.农业和林业的扩大，及其相关肥料的使用(氮和磷)将严重改变这些营养素在自然界的循环；c.为了农业灌溉、工业及废弃物弃置的需要，所需增加的淡水系统开发。) |
| integral natural reserve Areas allocated to preserve and protect certain animals and plants, or both. They differ from national parks, which are largely a place for public recreation, because they are provided exclusively to protect species for their own sake. Endangered species are increasingly being kept in nature reserves to prevent them from extinction. Nature reserves also serve as a place for more plentiful species to rest, breed or winter | 综合自然保护区 (用以维持和保护某些特定的动物、植物或两者兼而有之的地区。国家公园大部分是公众休闲的地方，与国家公园不同，自然保护区是专门用来保护物种的。濒危物种越来越多地被放在自然保护区，以防止其灭绝，自然保护区也成为更多更丰富物种的休息、繁殖或过冬的地方。) |
