Nihilism can also lead to compromising lifestyles. For example, when the movie 2012 came out a lot of people sold their houses. They thought that if the world was going to end they may as well enjoy life now, and forget about everything that is "important" like paying bills.
I believe that nihilism plays a strong role in the creation of religions. The question why are we here, can never be answered, and due to this I believe religions were created, to give humans purpose. It establishes why we are here and gives us something to work towards.
