First of all i would like to thank my honorable teacher to arrange this seminar.after join this seminar,Ilearn so many things about our resources.Our resources are scares so we have to utilize our resourses in proper way.In order to protecting our environment we have to change our habit.But I think one seminar is not enough to this purpose.
