The third major problem is the lack of leadership in Pakistan.

Exactly Esha you are right there is lack of leadership. As you know the present condition of our political system. The person who deserve the government is too much away from government now.

The other big problem is pollution in Pakistan.

Pakistan is among those countries who are most polluted in the world 🌎.
