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.
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.
Объяснение:
films are probably the nicest and most relaxing thing that people have invented. they help to distract from all the problems, so I often watch movies. I really like the fantasy genre because it shows a world where the unreal can become real. I like to watch films at home, as there are a lot of people in the cinema and you shouldn't make any noise here. but at home, you are alone and you can look the way you want. my friends, who know that I am a film fan ,constantly ask what kind of movie I would recommend. I always recommend to watch "The Avengers"
