80 We must travel this road together, united in minds and hearts. Hence We feel it necessary to remind everyone of the seriousness of this issue in all its dimensions, and to impress upon them the need for action.

Can world peace and human civilization be preserved intact? Every individual and every nation must face up to this issue, for it is their problem.
