What is it like to live in a megacity where the air is toxic? What are the causes and consequences of these extreme levels of pollution? How can we capture and transmit this dire situation through images?

In this 15-minute visual talk —the first of many we hope to present at Sonda Internacional—, photojournalist Santi Palacios explains the project Megacities and Pollution: The Asian Epicenter, focusing on the situation in Delhi, the capital city with the worst air quality in the world. In this visual journey narrated through the lens of his camera, Santi Palacios describes and illustrates the blanket of smog that covers this megacity. 

The talk was recorded on September 21, 2022 during the first public event of Sonda, held at the Teatre Principal de Arenys de Mar (Barcelona).
