Zambia and Zimbabwe are urgently trying to raise $250 million to make repairs to the massive Kariba dam.

The dam is one of the world's largest, spanning the Zambezi River that forms a border between the two countries.

But cracks have appeared, and people living below the dam are worried that it could collapse and trigger a disaster.
