:Firstly,because The technologies we are using today release different types of pollution on land,water resources and air,the governments can allocate a lot of research funds to develop new technologies that will eliminate or at least reduce the pollution being generated today without causing any hardship to our lifestyles.Secondly,I think it is of great significance to promulgate a law if someone pollute the environment badly.Are there some more ideas in your mind.
B:the public awareness of environmental preservation should be raised.Only in this way,can we realy have a more livable /inhabitable environment and have a sustainable development.
