Water Protectors engineered a makeshift wooden pedestrian bridge over the Cantapeta Creek. They were trying to access ancestral burial grounds they believe are being damaged by the Dakota Access Pipeline construction. Heavily armed law enforcement officials were deployed. As they pulled the bridge apart with boats, the Water Protectors swam and used their own boats to cross the water.

Standing unarmed in the cold water, the protectors were forcibly repelled by the enforcers with tear gas, pepper spray and rubber bullets. Standoffs between the Water Protectors and law enforcement over the Dakota Access Pipeline continue in the area that has become ground zero for opposition to a $3.7 billion project that would move domestic crude oil across four states and destroy tribal lands.

Two ships leave the harbour at the same time in Dakar, Senegal. The Senegalese sailors look at the Chinese crew on the other ship. The depletion of China's domestic fishery resources, which resulted from irresponsible fishing activities in China's coastal water and poor fishery management, has forced Chinese fishing vessels to travel over tens of thousands miles to find fish in other fishing grounds like the one near West Africa.
