It is very sensitive to ditermine the context of word we use. by "new" I can understand unprecedented thing; thus new world may mean totaly new world with novel facts and effects.
as such it is impossible, from my point of vies to look for a new world, but we can introduce ameliorations that facilitate the difficulties of every day life.
further i think that the contemporarly worl is not our own possession, but is further the possession of our ancestors and those who will come after us.
