It is no a secret that the past 50 years have seen a tremendous leap and bounds in technologies and (mega) construction. Although everyone is excited about it, this also raises the question, whereto? The idea that out of the thousand years humans have been in this world, only the past half a century has seen an unparalleled spring in materialism (humanism has deplorably spiraled down, perhaps this shows a reversed correlation?). Using Google Earth Engine Timelapse, I have captured how my hometown, Tripoli, Lebanon, has transformed (amorphously) in the past 32 years (1984 – 2016). Timelapse is a global, zoomable video that lets you see how the Earth has changed over the past 32 years. It is made from 33 cloud-free annual mosaics, one for each year from 1984 to 2016. Using Earth Engine, we combined over 5 million satellite images acquired over the past three decades by 5 different satellites. The majority of the images come from Landsat, a joint USGS/NASA Earth observation program that has observed the Earth since the 1970s. Here’s the video
Based on screenshot images, you can notice how a massive shift in construction, and destruction of green areas, has taken place at key years, specifically between 2010 and 2016. If 32 years have done that damage to our world, and have drastically increased urban density, imagine the world in the next 30 years. Would you wish your children to live in such a place?






Misty Adoniou , University of Canberra A couple of years ago, early one morning, I received an SMS advising “resadents to stay indoors because of a nearby insadent”. I was shocked by the spelling, as much as the message. Surely, I thought, if it was a real message then the spelling would be correct. Spelling matters. In a text message from a friend teeing up a night out “c u at 8” is fine - but in an emergency warning text from a government agency, I expect the spelling to be standard. But why is it that some people struggle with standard spelling? Spelling remains the most relentlessly tested of all the literacy skills, but it is the least taught. Sending a list of words home on Monday to be tested on Friday is not teaching. Nor is getting children to write their spelling words out 10 times, even if they have to do it in rainbow colours. Looking, covering, writing and checking does not teach spelling. Looking for little words inside other words, and doing word searches ar...
