Bono is issuing a dire warning to the world.

Speaking at the World Economic Forum in Davos, Switzerland, the U2 frontman called on the world to step up its fight against HIV/AIDS, explaining that 7,000 women around the world are being infected each week.

“We could lose this thing,” he said, according to the Guardian. “We were winning. We have been somewhat put on the back foot by the understandable concern in northern economies that we have problems in our own cities. If there are people on the streets in our own cities, why should we care about what’s going on over there?

“The answer is that what is going on ‘over there’ affects us. If Africa loses, Europe can’t win. But we have got to get back into the conversation. We need a response to what is going on in our own cities.”

The 58-year-old singer also warned that while the current capitalist system has helped raised billions out of poverty, “it is a wild beast. If it is not tamed it can chew up a lot of people along the way.”

He also explained that as western governments fail to invest in Africa, the hole will be filled by China.

“China is the elephant in the room,” Bono said.
