The Lascaux Cave is one of 25 caves from the Palaeolithic period located in the Vézère Valley—part of the Nouvelle-Aquitaine region in southwestern France. Inside the cave, Upper Palaeolithic occupation (dated between 28,000 BC and 10,000 BC) is evidenced by the presence of 6,000 painted figures—of which animals are the main focus—as well as hundreds of stone tools, and small holes along the cave interior that archaeologists suspect may have reinforced tree-limb scaffolding used by painters to reach the upper surfaces.
On the Ramu River in Papua New Guinea, the Songnor have thrived for 6,000 years. Indigenous people living along the Ramu River fear that runoff from the ongoing construction of the massive Chinese government-owned Ramu NiCo mine will poison their water, fish and gardens, and destroy their environment. Those along the coast worry about about the mine waste being dumped at sea and its effect on their health and fisheries.
