About 20% of kids in our classrooms believe the world will be destroyed before they reach adulthood. Another 20% are not quite sure.
A surprising number have been taken in - unknown and to their parents' and teachers' horror - by TV shows that claim the Mayan Calendar is coming to an end, so the world will break apart in 2012. (Neither claim, of course, is true).
Others are frightened by stories of global warming and climate change - which humans have faced and conquered in the past, too - or by the violent 'adult world' they see portrayed on TV and especially in video games, where friends shoot you with virtual machine guns.
A hundred and twenty years ago children in Australia worked in factories for low, sometimes no, wages. Fifty years ago the kids from the orphanage in our suburb begged for the scraps from our school lunches.
We are better at providing food, shelter, and education for kids now. Not perfect, but pretty good.
What we need to give our children is hope; the knowledge that we humans are a tough and resilient species, and have already survived far worse than the next few hundred years will throw at us.
We can tell them this, but the best way we can convince them is by example; by showing them that we truly believe that tomorrow can be better, by working for it, and committing our lives to it.
All of the extraordinary people who will receive Awards this Children's Day do that for kids. They give our children many, many things. But most of all, by showing that they believe in our future by working to make this a better world, they give kids hope and power.
