1. But rock phosphate is a finite resource and the biggest supplies are mined in politically unstable places, posing risks to the many countries that have little or no reserves.
2. Phosphate use has increased in the last 50 years as the global population has grown and the date when it is estimated to run out gets closer with each new analysis of demand.

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.

i’d like to tell you about a book by a russian novelist, nikolai gogol. it’s called “the government inspector”. it’s a satirical play. i’ve recently read this book in my literature lessons.
let me tell you a bit about this book. the action takes place in a small provincial town. the main character is khlestakov. he’s a young man who is silly and broke. but he’s a very self-loving man. he tells lies with pleasure. khlestakov has careless a fantasy. he arrives in the town and is mistaken for the government inspector.
as you can imagine, the plot is very interesting and funny. the comedy shows human stupidity and greed. also the problems of society are shown there.
