In this episode we look to evolution to explain grief. We find out why and how humans grieve and ask, are we the only animals that do?
How many people can the Earth really support? And if the world is already over-populated, are we morally obliged to not have children?
Where did countries and national identities come from? Are countries the best way to organize people, and could we imagine a world without countries?
More than half the world's population now lives in cities. We find out how urban life changes our brain structure, and we wonder if it's possible to build cities that make us happy.

Life Matters is a 13-part series that asks some really big questions about how we run our world, and how we treat each other and the other species who share the planet with us. We explore the ethics of having children in an overpopulated world; we ask if we have moral obligations towards animals or if we can treat them any way we choose; we wonder if it's possible to really forgive; we blast off into space to find out if religion is an Earth-bound construct, or if we need it in space too.
