Rise of the Machines (and Biology)

From the New York Times:

"Half a century ago, harvesting California’s 2.2 million tons of tomatoes for ketchup required as many as 45,000 workers. In the 1960s, though, scientists and engineers at the University of California, Davis, developed an oblong tomato that lent itself to being machine-picked and an efficient mechanical harvester to do the job in one pass through a field."

A Paragraph to Ponder

From the Economist on the state of urban/suburban development: 

"As it has done before, Florida is pioneering a new kind of city. Robert Bruegmann, an authority on urban sprawl at the University of Illinois, reckons that American city centres and suburbs are coming to resemble one another. Suburbs are growing denser and more diverse; urban cores are greener, cleaner and often less densely populated than they were (even go-go Manhattan has two-thirds as many people as it did a century ago). Ersatz city centres, which can be built in low-rise suburbs like Sunrise or in built-up areas, bulldoze the distinction further. South Florida is becoming a landscape of scattered centres—sprawl with bumps."
