This show is made up entirely of amateur images. We've seen time and time again how images captured by ordinary citizens then uploaded onto the Web can change history, or at least shift the balance of power. This week, we take a look back at some of those moments.
STORY 1: INDIA
We begin today with a clash of civilizations - modern tourism on the one hand, and a tiny tribe of indigenous people on the other. It happens in India's Andaman Islands. There are just a few hundred people in the Jarawa community. Their isolation helped them survive the ravages of British colonisation, but today they're coming into increasing contact with the modern world - often as the subject of commercially-run "human safaris". Our Observer Pankaj Sekhsaria has the story.
STORY 2: CHINA
Our next stop is Hong Kong. It's been 15 years since the former British colony was handed back to China. The quintessentiually capitalist city was allowed to retain its own political and legal system, and a degree of autonomy.
The Chinese call it "one country, two systems". And many Hong Kong Chinese want to make sure it stays that way. They can be very sensitive about their special status - even over matters that could seem trivial. Here's our Observer Kay Lam.
STORY 3: WORLD
Now for our weekly look at the best images and stories sent in by our Observers.
We begin in Ukraine, with Alexander Hirczy. Ukraine is getting ready to host the Euro 2012 soccer tournament, along with Poland. The government wants visiting fans to see the best of their country, so they're cleaning up. Part of that is getting rid of stray dogs. They started out by simply killing them, en masse - but that didn't go down well with animal rights activists like Alexander. They started a campaign, and the government finally agreed to use more humane methods. But it's not happening, Alexander says. Dogs roaming the streets are still being killed, and their bodies showing up in the country's garbage dumps.
We end with a video sent in by one of our Observers in Syria, Ammar. For more than 10 months now, Syrians have been taking to the streets to demand the resignation of President Bashar al Assad, and they’ve been met with deadly repression. In hotspots like the city of Douma, it’s a day-to-day reality that children, too, have been living with. Ammar tells us the children in his city support their parents - and copy them... He shot this video one day after school got out. They sing the same chants and make the same speeches as the adults. When he asked one of the children to define freedom, he said "living with dignity, and not being killed.”
