7 billion (7,000,000,000)
The number of people on Earth topped the 7 billion mark today according to the United Nations Population Fund. The 6 billion mark was crossed in 1999 and it took the entirety of history until approximately 1804 to reach the 1 billion population figure. Different projections have the figure reaching between 8 billion and 10.5 billion by 2050, although if the population growth over the past decade were to be used as the basis for future growth – the global population would be between 12 and 13 billion by 2050 and between 18 and 20 billion by 2100.

This fascinating piece from TED puts in perspective the brevity with which us humans grace the face of this planet. Rachel Sussman highlights those organisms that have been alive continuously for more than 2,000 years:

Can you imagine what live would look like without GPS? Anyone who is older than 20 years old can easily remember a time when cars were sold without that (still) expensive factory option or perhaps even a time when your phone wasn’t able to direct you to the nearest sushi restaurant in a pinch. However those days are long over. The 24 satellite constellation that perpetually provides a blanket of location-based signals to the more than one billion receivers 12,000 miles below on Earth has become so ingrained in our modern way of life I hardly imagine that we could – or would want to – part ways with it now. I’ll avoid a long diatribe about what this system means from a social control perspective but suffice it to say that we have willingly given up some degree of autonomy and privacy in exchange for glorious convenience – and I’m including myself in this backhanded indictment. The good news for all of us is that one by one the 24 satellites will be replaced and the entire system upgraded to improve not only the reliability but also the accuracy. The current 20 foot margin of error will be tightened to roughly 2-3 feet.
There are some obvious benefits to this upgrade. The first is simply that better is better. We expect “bigger, better, faster, more” in all walks of our lives, so why should GPS be immune? The second is – and I am making a leap of faith here – that overall system speed and capacity will be improved. This is a fair assumption given what I know about technology systems and it certainly follows logically. Lastly and most intriguingly, it opens the door to a host of hyper-specific location-based applications. For example, an embedded transmitter can tell the frantic owner of a lost pet the precise location of their furry family member or – more provocatively – imagine a social media application that would allow large groups of people (i.e., festivals, sporting events, or even dense metropolitan areas) to interact in new ways. Citywide game of tag anyone?
