Question

how monsoon acts like a unifying bond

Answer 1

monsoon is know as unifying bond because as 75% of indian farmers still depends upon rainfall for the irrigation purpose. and we also know that monsoon is one of the major factor for this , so as per my observation
The Indian Monsoon turns large parts of India from a kind of semi-desert into green lands. See photos only taken 3 months apart in the Western Ghats. In places like this it is crucial for farmers to have the right timing for putting the seeds on the fields, as it is essential to use all the rain that is available for growing crops.
