Greenpeace's Unearthed

Beijing, China — China's poverty-stricken northwest is swathed in sand. The deserts are creeping over ever larger areas, in part because of weather changes linked to climate change. Sean Gallagher a young British photographer travelled to Ningxia to document China's growing sands.

"You can smell a sandstorm.

As I woke this morning, my throat was drier than normal and the smell of dust and sand had crept into my room whilst I was sleeping.

I opened my curtains expecting to see the Yellow River out of my window but all I could see was a haze of yellow light."
