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.

Dear Tom,
Thank you for your letter. Sorry, I have not written you, because I was very busy.
As for me, I am going to visit you next week. Firstly, I think it will be great to go shopping . Thus, we can buy a lot of different things. Secondly, I want to visit a new museum. Frankly speaking, I have heard that there are a lot of beautiful pictures in it. Moreover, I want to meet your new friend. We can together go to the cinema.
By the way, what are you going to do? Will we visit your grandmother? What do you want to show me? And how about going to the club?
