3. With some scientists projecting that moment could come as soon as a few decades’ time.
4. “Phosphate supply is potentially a very big problem,” said Martin Blackwell, at Rothamsted Research, an agricultural research centre in the UK, and lead author of a new study. “Currently the population is growing and we are going to need more food.”
5. “In a few years' time, it could be a political issue with some countries effectively controlling the production of food by having control of rock phosphate supplies,” Blackwell said.
