The post entitled 'Earth Without Humans' from Dec 1st is worth a read. It is an article by Alan Weisman from Discovery Magazine in 2005. It talks about what would happen to the planet if humans suddenly disappeared. Here are a few paragraphs that I liked:
The new wilderness would consume cities, much as the jungle of northern Guatemala consumed the Mayan pyramids and megalopolises of overlapping city-states. From A.D. 800 to 900, a combination of drought and internecine warfare over dwindling farmland brought 2,000 years of civilization crashing down. Within 10 centuries, the jungle swallowed all.
Mayan communities alternated urban living with fields sheltered by forests, in contrast with today’s paved cities, which are more like man-made deserts. However, it wouldn’t take long for nature to undo even the likes of a New York City. Jameel Ahmad, civil engineering department chair at Cooper Union College in New York City, says repeated freezing and thawing common in months like March and November would split cement within a decade, allowing water to seep in.
As it, too, froze and expanded, cracks would widen. Soon, weeds such as mustard and goosegrass would invade. With nobody to trample seedlings, New York’s prolific exotic, the Chinese ailanthus tree, would take over. Within five years, says Dennis Stevenson, senior curator at the New York Botanical Garden, ailanthus roots would heave up sidewalks and split sewers.
That would exacerbate a problem that already plagues New York—rising groundwater. There’s little soil to absorb it or vegetation to transpire it, and buildings block the sunlight that could evaporate it. With the power off, pumps that keep subways from flooding would be stilled. As water sluiced away soil beneath pavement, streets would crater.
“America would have three times as many species of animals over 1,000 pounds as Africa does today,” he says. An amazing megafaunal menagerie roamed the region: Giant armadillos resembling armor-plated autos; bears twice the size of grizzlies; the hoofed, herbivorous toxodon, big as a rhinoceros; and saber-toothed tigers. A dozen species of horses were here, as well as the camel-like litoptern, giant beavers, giant peccaries, woolly rhinos, mammoths, and mastodons. Climate change and imported disease may have killed them, but most paleontologists accept the theory Martin advocates: “When people got out of Africa and Asia and reached other parts of the world, all hell broke loose.” He is convinced that people were responsible for the mass extinctions because they commenced with human arrival everywhere: first, in Australia 60,000 years ago, then mainland America 13,000 years ago, followed by the Caribbean islands 6,000 years ago, and Madagascar 2,000 years ago.
Yet one place on Earth did manage to elude the intercontinental holocaust: the oceans. Dolphins and whales escaped for the simple reason that prehistoric people could not hunt enough giant marine mammals to have a major impact on the population. “At least a dozen species in the ocean Columbus sailed were bigger than his biggest ship,” says marine paleoecologist Jeremy Jackson of the Smithsonian Tropical Research Institute in Panama. “Not only mammals—the sea off Cuba was so thick with 1,000-pound green turtles that his boats practically ran aground on them.” This was a world where ships collided with schools of whales and where sharks were so abundant they would swim up rivers to prey on cattle. Reefs swarmed with 800-pound goliath grouper, not just today’s puny aquarium species. Cod could be fished from the sea in baskets. Oysters filtered all the water in Chesapeake Bay every five days. The planet’s shores teemed with millions of manatees, seals, and walrus.
You can read the rest on the site :) This kind of thing is so interesting. It reminds me of The Drowned World by J.G Ballard. Except there were some humans alive still in that book. Still an interesting concept and good book!
All this talk of lush nature reminds me of when we went to PARADISE in the Otway Ranges. It is mangificently beautiful, it's hard to believe it is located so close to a beach! Here are a few shots of Josh and his big tree at Paradise . He gave it a hug and everything :)
We are going back there next month to celebrate our 5 year anniversary :D so that should be sooo amazing! We are both really excited - especially me because i booked this awesome cottage on stilts standing over a lake! Sweet, can't wait! Enjoy looking at that website! I haven't looked at too much, but it seems freakin awesome!
