There are massive intractable problems with human society on earth at the moment which lack easy solutions (poverty, aids, overpopulation, climate change, social order).
Poverty—has always been with us. Many, many people are better off.

Overpopulation—Population will stabilize at 10 billion. See 2nd link.
Climate change—see below.
Social order—so long as we don’t extinguish ourselves, this will work itself out.
