On the outskirts of Dhaka there are about 1,000 brick factories. 90% of them are considered illegal by the Bangladesh government because the stacks are too low and also for the use of coal as a fuel. The toxic fumes they emit are the cause of 40% of the pollution in the city of Dhaka. Next to each factory there are the villages of workers. Whole families are forced to work for 15 hours a day without any right and with a salary that allows them only to survive miserably.
