用译入语(中文)概述讲话内容,不超过3句: The protection of the environmen is a vital component of continued economic development here and in Hong Kong. Decades of explosive growth have taken a toll on the environment resulting in air and water pollution, destruction of the natural environment, traffic congestion and deforestation. Not only does this discourage further economic investment and encourage industries already here to relocate, but it also makes it increasingly difficult for Guangdong to enter into the next level of economic development.
