As a member of nature we man have searched for the answer for long. During the process from the originally finding one\'s feet to the struggle we have left a string of foot steps in the World History including many a sweets and hitters.
Definitely man can conquer nature to some extent. For instance we can implement artificial rain at arid areas we can travel to another planet by the spacecraft we can communicate by telephone and the like. Yet for another massive things we can\'t exactly control such as earthquake flood and so on exist in nature which frequently result in tragedies.
Often in a war nature plays an important role. For example in part Grass Boat Borrow Arrow just took advantage of the nature. Additionally a word said by Darwin "Only obey the nature can we triumph over the nature " describes appropriately the relationship between the nature and man.
Therefore from my part man just can triumph over nature in a range out of which the thing we achieve is only the fail.
