编辑同志: 前不久,我的鱼池里有大批鱼突然死亡,后来请了有关技术人员检验查明,是由于附近一家新建工厂的烟囱排放出的有毒气体所致。为此,我们多次与该厂交涉,要求迅速采取改进措施,以保障群众健康,并要求赔偿经济损失,但该厂竟置之不理。请问,我该怎么办? Edit Comrade: Not long ago, a large number of fish in my fish pond died suddenly. Later, the technicians were asked to inspect and verify that it was caused by toxic gases emitted from the chimneys of a nearby new factory. To this end, we have repeatedly negotiated with the factory and demanded that prompt improvement measures should be taken to safeguard the health of the people and demand compensation for economic losses, but the factory ignored it. Can you tell me what to do?
