A country of 170 million people canont just 'die'.
Do you think we are the only country facing power shortage? India faces the same problem. Even European countries are facing the same problem. A few days ago my power went out.
Prices are going up because Pakistan's per capita income is increasing and people have more money to buy goods, but our production of the goods is not keeping pace with the increased demand, hence the prices are rising. Due to this we need to import, which causes our Rupee to weaken against the dollar. All we need is a good finance minister to solve this problem.
And btw, agriculture is only 20 something % of our economy. Services sector is the largest sector of our economy now.
As for availability of water, did you know that the government is constructing desalination plants and scientists say it is going to rain and snow more and more in Pakistan due to global warming? This means we will have plenty of water in the coming years.
I have heard this doomsday scenario for a long time, since 9/11. Pakistan has an ability to absorb a lot of dangerous situations, our government has learned how to deal with it.
Pakistan will be around till the end of time, nobody can kill it
