Nothing is as daunting as the threats associated with global warming. That's the biggie. Everyone bangs on about rising sea levels but the real challenge of a warming planet is ocean acidification. An acid ocean spells the end of life on earth.

Surfing is sensual. It's a real-time engagement with the forces of nature, which happen to be echoes of the past (which after all, is all a wave really is). Briefly we defy gravity and ride the energy of storms from elsewhere. We are intensely alone as we do it and yet completely swallowed by something larger that enforces a sense of perspective and connectedness to the natural world. It's an experience we yearn to repeat so we go searching for it again and again and we spend years sitting in the water waiting for these radiating lines to come in across the event horizon.

The ocean is a supreme metaphor for change. I expect the unexpected but am never fully prepared.

Doing nothing is making certain you lose. Which is just gutless.

Yet however comforting and peaceful beach-combing is, it ends up like the sea, as disturbing as it is reassuring. In dark moments I believe that walking on a beach at low tide is to be looking for death, or at least anticipating it. You will only find the dead, the spilled and the cast-off. Things torn free of their life or their place.

It's the pointless things that give your life meaning. Friendship, compassion, art, love. All of them pointless. But they're what keeps life from being meaningless.

I've been a writer and a parent since adolescence, it feels like, and I'm still making both gigs up as I go along. I did both in different forms of isolation - too young by conventional standards, too far off-grid culturally and geographically. So my experience is probably too specific to be useful. None of us do this stuff the same way. We just try to endure and press on, I guess.
