During the 1950s somne observers began to warn that many other products of technology also had harmful or destructive aspects. Automobile exhausts,they pointed out, were polluting the atmosphere,pesticides such as DDT were threatening the food chain ,and mineral wastes from a wide variety of industrial sources were polluting large reservoirs of groundwater.Indeed,the physical environment has become so jammed with technological processes that one of the major challenges of modern society is the search for places to dump the wastes that have been produced.
问题补充：例如:
Indeed， research has shown that people who forgive report more energy， better appetite and better sleep patterns.分析一下，首先research has shown(研究表明)，这是一个主谓宾结构，是句子的主句；宾语是由连词that引导的一个宾语从句people who forgive report more energy， better appetite and better sleep patterns.这个宾语从句的主语是people，谓语是report，宾语是more energy， better appetite and better sleep patterns；who forgive是定语，修饰的是people ，什么样的人们呢，是怀有宽恕之心的人们。到这里，全句的意思就清楚了，按照汉语的思维来整理，

这是一段话，不是一个句子。
这段话由三个简单的句子构成。第一句话到到destructive aspects.第二句话到groundwater,第三句话到末尾。
先分析第一句话，During the 1950s somne（这印错了是some多了一个n) observers began to warn that many other products of technology also had harmful or destructive aspects.开头During the 1950s 是介词短语作壮语，表明时间“在1950年代期间（是指1950－1959这几年期间），some observers 显然是句子主语，”一些观察者（观察家）“began是谓语动词，began to warn这个动词不定式短语成为完整谓语，”开始警告说“，that 引导了一个宾语从句，作为”warn"的宾语，即警告说的内容，many other products of technology这部分是从句的主语，从句的谓语是had"具有“，从句宾语是后面的aspects"方面”，前面的harmful or destructive 作为宾语aspects修饰性定语，意为“有害的或破坏性的方面”。全句意思是“在5，6十年代一些观察家就开始警告说许多技术（的其它产品）同时也具有有害性的或者破坏性的一些方面” 明天再接着分析第二句
