科学家日前在敦促大幅度增加森林保护区时警告说,东南亚橡胶园的扩张可能对环境产生“毁灭性”的影响。在中国、泰国、越南、老挝、柬埔寨和缅甸的丘陵地区,可能已经有超过50万hm2(120万英亩)的橡胶园。研究人员预测,到2050年,专门用于种植橡胶和其它农作物的土地或将增加2~3倍 In a recent move to urge a substantial increase in forest reserves, scientists warned that the expansion of the rubber plantation in Southeast Asia may have a “devastating” impact on the environment. In the hilly areas of China, Thailand, Vietnam, Laos, Cambodia and Myanmar, there may already be more than 500,000 hm2 (1.2 million acres) of rubber plantations. Researchers predict that by 2050, land dedicated to growing rubber and other crops may increase by 2 to 3 times
