The recent verdict by a French court stopping the deportation of an unnamed Bangladeshi on the grounds of deadly air pollution in Dhaka has raised eyebrows among many of us. In some of our newspapers and portals, an undertone of ridicule and aspersion against the assumed lack of patriotism in him was evident. Environmentalists, however, celebrated it as a landmark ruling as governments will now have to take tackling air pollution as a matter of urgency to prevent mass migration. For the last few decades, we have heard a lot about climate refugees, mostly as a result of forced displacements following extreme natural events or disasters caused by climate change. However, the person in question is probably the first legally recognised "pollution" refugee of the world.
