Environmental pollution has a great impact on human health, ecosystems, and financial development. This paper depicts the recent studies on the severity of environmental pollution in developing countries. Its remedial measures were based on a questionnaire survey in the polluted sites, which collected data and information on the types, causes, effects, sources, and duration of environmental pollution, obtained from available publications and newspaper information reported in recent years. A total of 400 respondents from 10 zones of Dhaka City Corporation, Bangladesh, were interviewed as a case study via a semi-structured questionnaire survey. The results revealed that only 39.0% of respondents had explicit knowledge about environmental pollution. Air pollution was identified by 73.8%, noise pollution by 63.0%, water pollution by 55.2%, and soil pollution by only 6.5% of respondents in their surroundings. Automobiles, domestic activities, municipal garbage, and vehicle horns are significant sources of environmental pollutions. Around 49.0% of the respondents did not understand the effectiveness of currently conducted environmental programs. A discussion regarding the urgency of forming a local level environmental committee, the mass media’s active role, and monitoring the development activities was presented.
