What respects does Bradbury touch life in his novel?What relevance does the novel have for th 21st century?

Really your fist question has to do with themes. This book is a dystopia which comments on censorship and freedom of information. A world where freedom of information is so tightly controlled is most certainly a world devoid of real feeling and meaning. We learn from literature, without it we have no past or future. We need the ideas of the past more than ever today. We need the wisdom of experience and pain of the past as our world embraces the superficial and the disposable.
