Let me mention two places!
The first one is the Freeport Copper Mine or Grasberg Mine in the Indonesian part of New Guinea. I had crossed this huge territory three times, always illegally. 25 years ago it was a weird place, a HiTec area surrounded by a Stone Age society. 15 years later the Stone Age has disappeared and the mine had left a ruined environment where human rights were completely ignored. The real owner of this territory, different Papuan tribes have been forced to leave the area long time ago and are currently not even allowed to cross the mine territory.
The other place is the waste disposal site on Fongafale Island, the most populated island of Tuvalu. The island is 12 kilometres long and 10-400 metres wide. As the people cannot get rid of their waste, they started to dispose it on the northern tip of the island. 7 years ago this waste disposal place had already a length of 1,5 kilometres and is continually growing.
