材料分析题

2009年水污染事件：因韶关冶炼厂设备检修期间超标排放含镉废水，导致北江韶关段镉严重超标，严重威胁下游饮用水源安全；山东胶州村庄因企业违法排污，水源受污染，五年20余人患癌症，同时大多数村民家的井水都因含很多杂质而无法饮用；由于自来水水源受到化工污染，江苏省盐城市区发生大范围断水，至少20万居民的生活受到影响。

（1）请你结合材料多角度分析水污染事件频繁发生的原因。

                                                                                                                                                                

                                                                                                                                                              

（2）为减少水污染事件的频繁发生，请你提出几条可行性建议。

                                                                                                                                                               

                                                                                                                                                               

（3）有人认为，要加快经济发展就必然会破坏环境，注重了环境保护就会影响当地经济的发展。这种观点对吗？为什么？
