Free The Human Age by Diane Ackerman

not anticipating a stumble overboard, but like many a fisherman Bren doesn’t swim, and the suit adds needed warmth through high winds and snow-thunder in the recent cannonade of winter storms.
    A perennial mariner, he grew up in Petty Harbour, a five-hundred-year-old Newfoundland town with eleven painted wooden houses filled with fisherfolk and a salt-peeled wharf with jostling boats. On the rocky shore, a boy could find lobster cages, floats, anchors, ropes, seaweed-tangled shells, fish and bird skeletons, and tall tales. So it’s not surprising that, at fifteen, he dropped out of high school and ran away to sea. In Maine he worked on lobster boats, in Massachusetts on cod boats, and in Alaska’s Bering Strait on trawlers, longliners, and crab boats. At one point he factory-fished for McDonald’s.
    “Do you think of yourself as a fisherman or a farmer?” I ask.
    “A farmer now. It’s more like growing arugula than facing the dangers of the sea—which, believe me, I’ve seen.”
    In a sense 3D farming is rotational agriculture. Bren harvests kelp in the winter and early spring; red seaweed in June and September; oysters, scallops, and clams year-round; mussels in the spring and fall. At least that’s the theory. Hurricane Irene tore up his oyster beds, which he promptly reseeded, knowing he’d have to wait two more years for harvest. Hurricane Sandy smothered the oyster beds yet again. Clams have a better chance of surviving a hurricane because they at least have a strong foot and can move a little. But oysters really are trapped. They don’t even move to eat or mate. Without the reefs, storm surges churn them up, and as the silt smothers the oysters they die, beginning the slow process of joining the fossil record. Right along with the Model Ts that sank when the Long Island Sound froze over in 1917–1918 and foolhardy souls tried driving across it.
    “Ironically,” Bren says thoughtfully, “I may be one of the first green fishermen to be wiped out by climate change.”
    But Bren is upbeat and confident. Fortunately, he was able to harvest some mussels in the thick of a snowstorm, just before Blizzard Nemo hit. Kelp, at least, is a post-hurricane-season crop. After Sandy he began planting the year’s kelp, and now, in mid-February, it’s nearly ready for harvest.
    Unmooring the dinghy, Bren hops back in, and we motor out to his solar-powered fishing boat, placid as a tiny icebreaker half a mile offshore. En route, we weave through the Thimble Islands, an archipelago of islets, some with majestic cliffs of 600-million-year-old pink granite. Many are topped by stilted, turreted, luxe storybook houses with long wooden staircases winding down to the water.
    A receding glacier left behind this spill of islands: massive granite knobs, stepping-stone slabs, and submarine boulders and ledges, some of which only appear at low tide. Named after wild thimbleberries, not thimble-sized cuteness, the cluster includes Money Island, Little Pumpkin, Cut-in-Two Island, Mother-in-Law Island, Hen Island, and East Stooping Bush Island, among many others—between 100 and 365 (depending on the height of the tide, how you define an island, and if you cherish the idea of an island for each day of the year), with around twenty-three of them inhabited by people during the summer. Harbor seals and birds abound. Each island is cloaked in its own gossip and lore, thanks in part to famous sojourners, from President Taft to Captain Kidd and Ringling Brothers’ Tom Thumb.
    As saltwater and river water mix in the estuary, it offers a feeding and breeding refuge to 170 species of fish, 1,200 species of invertebrates, and flocks of migratory birds. Horse and Outer islands are wildlife preserves. For Bren it’s a fertile garden visited in summer by flocks of seasonal guests and in winter by tumultuous storms, but always spawning life above and below the surface.
