to the global air and water pollution caused by industrial wastes. our ruthless exploitation has permanently impaired our mother earth. as we tragically learned from last summer's floods. we cannot continue our carelessness. finally, standing here at the threshold of the 21st century, we cannot help thinking of our posterity. nature is not only the mother of the present generation, but also the mother of the generations to come. how severely our descendents will criticize us if we leave them a barren and lifeless mother? how much more they will appreciate us if we give them a world of harmony to inherit? let us start respecting and caring for nature from now on. let us start the campaign of creating a mutually beneficial relationship between people and nature right from this moment. with this new start, i firmly believe, that our children, and our children's children will live in a brand new age of green trees, clean air, crystal water, blue sky and an even more promising world! ……………………
