There would be no call for ecological campaigning had nature not been exploited and abused. We experience the ground now bringing forth thistles as soil erosion devastates formerly arable land and deserts overtake fertile farms. Rivers and the atmosphere are polluted thoughtlessly and we are fearful of the consequences of a depleted ozone layer and the devastation of the greenhouse effect. We are not quite at home in our world, and somewhere in each of us there is a nostalgia for a paradise that has been lost.

We must not allow ourselves to become like the system we oppose.

Forgiveness and reconciliation are not just ethereal, spiritual, other-worldly activities. They have to do with the real world. They are realpolitik, because in a very real sense, without forgiveness, there is no future.

When I talk of forgiveness I mean the belief that you can come out the other side ... a better person than the one being consumed by anger and hatred. Remaining in that state locks you in a state of victimhood, making you almost dependent on the perpetrator. If you can find it in yourself to forgive then you are no longer chained to the perpetrator. You can move on.

I mean in the South African case, many of those who were part of death squads would have been respectable members of their white community, people who went to church on Sunday, every Sunday.

You stand out in the crowd only because you have these many, many carrying you on their shoulders.

In most, when you go to church, most churches when they have images of the good shepherd, they show Jesus carrying a nice fluffy lamb. Now fluffy little lambs don't stray from their mommy's. The sheep that will stray is the most obstreperous, troublesome one.
