Answer 2

The Cause Defines the nature of Problem as there is a every reason behind every problem and also there must be solution . For Eg - Humans cut tress to benefit themselves for their needs for paper and furniture and when this continues in that particular area for several period of Time it turns into a desert where there is less or no rainfall which is a threat for the people who are planning for Desert Trips . So in this situation if humans had not cut down trees it would not have turned into a desert instead the trees would have provided several facilities to the people like sitting under their shed etc.
