The environmental situation of the world is degrading day by day and it is an “open secret” now – “open” because almost every human being knows it and “secret” because most people, who are somehow responsible for it, are indifferent to this fact and after knowing the consequences of this change. The heat of the earth is increasing; the characteristics of the main aspects of our environment: water, land, air, etc. have changed significantly. The ecological system has also been disturbed in some way. The main culprit of all these changes is mainly the human being. Human being has used this nature wrongly for his own good. In the name of progress he simply destroyed nature. In particular, industries along river banks, deforestation, misuse of animals in commercial sectors which destroy the balance of the ecosystem, are the main causes of unexpected changes in the environment. For economic progress, most of the countries depend on the industrial field today. Most industries are located on river banks and release their waste into river water, which is harmful to the water and the people who use it. The chemicals mix with the water which is undoubtedly very toxic and harmful to your health. In Bangladesh there is an example of river pollution. The Buriganga River of Bangladesh is a highly polluted river and one of the main causes is the nearby industrial zone. The chemical waste from these industries is making river water more and more dangerous every day (Bhowmik, “Buriganga Pollution: Reason & Prospects”). Even now the local population cannot use the water from that river. Here, it could be the industries that are important for the pr...... middle of paper ...... one's luxury. Industries, deforestation and killing of animals: these must be controlled if we want a safe earth for our future generation. If there will be no people living on the earth due to these devastating activities, what will be the use of wealth for what people today are ruining our environment? The cost of prosperity cannot be the death of humanity. Work Cited Bhowmik, Avit Kumar. "Buriganga pollution: reasons and prospects". ResearchGate. ResearchGate. May 2008. Network. 8 February 2014.
