"PORT RENFREW, British Columbia — The five-car caravan crept down a gravel logging road as the day’s last beams of golden light filtered through the trees. About 20 forest defenders were making a stand in southwest Vancouver Island, at a spot where a logging company was expected to cut old-growth trees the following morning. One truck parked sideways across the road. They awoke at 3 a.m., their headlamps tracing the ground, as they took their positions. A logging truck slowed, idled, then turned around.
