By the year 2050, Bangladesh will have approximately 220 million inhabitants and a large part of its territory will be permanently submerged. This could result in the forced displacement of between 10 and 30 million people from the country’s southern coastline, forcing many Bangladeshis to flee the country as “climate refugees”, a human group that is expected to reach 250 million people worldwide by mid-century.
On a planetary scale, we are talking about the largest mass migration in human history.
