Kolkata, in India, is a Metropolis boasting of a population of 5.3 million people most of whom live in apartment blocks. A green patch of agricultural land right in the heart of Kolkata with the apartments as a backdrop and flanked by the Metro Rail line is a rare luxury and acts as a lungs of a polluted city. The workers in the field planting rice saplings keep an eye on the overcast sky for early signs of rain as the fields try to bring a balance between urbanisation and nature.
