An employee in a bookshop adjusts packaged cigarettes which have to be sold in identical olive-brown packets bearing the same typeface and largely covered with graphic health warnings, with the same style of writing so the only identifier of a brand will be the name on the packet, in Sydney on December 1, 2012. A new world-first law forcing tobacco companies to sell cigarettes in identical packets came into effect Saturday in Australia in an effort to strip any glamour from smoking and prevent young people from taking up the habit.

It is amazing how much the humanity can change the face of the earth. Not only can it create huge craters, which look a lot like craters from meteors, they leave a big enough impact that it can be seen from space. Though this crater, caused by a massive explosion on 1 July 1916, looks large, being 90 feet deep and 300 feet across; it is nowhere big enough to be viewed for space. A common misconception is that the Great Wall of China can be seen from space. In reality, however, it is impossible. Not only is it of the same color as the earth near it, it is also not that wide. Deforestation, on the other hand, can be clearly seen from space. Also, at night, all the lights that the large cities produce are also very visible.
