The existence of life on Earth is threatened among other things due to climate change as a result of continuous environmental pollution.

For a long time, environmentalists worldwide have tried to get world leaders to focus on these and other pressing environmental issues.

Soon after the Stockholm Conference on Human Environment in 1972, the first environmental activities were undertaken in Bangladesh.

As a follow-up step to the Stockholm Conference, after the promulgation of the Water Pollution Control Ordinance in 1973, a project primarily aimed at water pollution control was taken up, funded by the Government of Bangladesh, under the supervision of the Directorate of Public Health and Engineering with 27 staff members.

Following the United Nations Conference on the Human Environment in Stockholm in 1972, the government of Bangladesh founded the Department of Public Health Engineering and passed the Water Pollution Control Ordinance in 1973.
