So you've decided to travel around the world. This is an excellent thing to do. It's a precious place, this planet. We should see it.

It is a remarkably easy thing to do, pointing out the faults of others and suggesting remedies or courses of action in an argumentative and pedantic sort of way, and I am still amazed that there are many people in the American media who are paid very big money to do this.

The gift of sobriety is clarity and a sense of connection - and travel only enhances that.

We don't think much about climate change and rising sea levels here in the U.S. Beyond a few gardeners, birders and hikers who notice the changes in our own ecosystem, we live on, blissfully unaware of our changing Earth. Our storms - Katrina, Sandy - are dismissed as once-in-a-century events.
