Right now, there about 1,100 satellites whizzing above our heads performing various functions like observation, communication, and spying. There are roughly another 2,600 doing nothing, as they died or were turned off a long time ago.
How did each of these satellites get up there? And what nations are responsible for sending up the bulk of them?
The answers come in the form of this bewitching visualization of satellite launches from 1957 – the year Russia debuted Sputnik 1 – to the present day. (The animation starts at 2:10; be sure to watch in HD.) Launch sites pop up as yellow circles as the years roll by, sending rockets, represented as individual lines, flying into space with one or more satellites aboard.

While the rest of the world is urbanizing, Latin America is urbanized. The region has four of the world’s 19 megacities (cities with populations over 10 million people) and 78% of all its people currently live in urban areas. Latin America’s concerns over urbanization, therefore, are based on the substantial amount of people currently in cities as opposed to the anticipation of populations to come. For example, of the one billion increase cities will experience by 2025, the United Nations estimates Latin America will only add about 127 million to its population. This is not insignificant for sure, but the slower rate of urbanization does change the nature in which urban planning occurs.

The signal public health achievement of the 20th century was the increase of the average human life span. Now, as that achievement helps raise the proportion of the aged around the world, what once seemed an unalloyed blessing is too often regarded as a burden — a financial burden, a health care burden, even a social burden.
“It’s nuts,” said Dr. Linda P. Fried, an epidemiologist and geriatrician who is dean of the Mailman School of Public Health at Columbia University. “To assume defeat from what every one of us as individuals wants suggests we’re not asking the right questions.”
Findings from the science of aging, Dr. Fried said, should “reframe our understanding of the benefits and costs of aging.”
From her perch at Mailman, a position she has held for four years, Dr. Fried is pushing students, professors and a wider audience to ask the right questions and ponder the right policies for coping with an aging world population.
Dr. Fried’s mandate is to lead a school that will give a new generation the tools to deal with global challenges to public health, including environmental degradation, climbing health care costs and the pressure of rapid urbanization. But she believes that research on aging and health changes “across the life course” are central to designing solutions to public health problems in the 21st century.

The outside of the map contains a series of predictions that get more playful and more provocative as you move out towards the edges. Click image to Enlarge. For example:
– There will be a convergence of health care & financial planning
– We will have face recognition doors & augmented reality contact lenses
– Online communities will start physical communities
The center of the map contains some mega-trends such as globalization, urbanization, sustainability, volatility, the power-shift Eastwards, ageing, anxiety and so on. But be careful. Trends like these can get you into all kinds of trouble. In fact they can easily get you into more trouble than predictions because people believe them.
