For centuries the area which is now Bangladesh was known throughout the civilized world for its fabled wealth, of which the exquisite muslin, Sundarbans, Cox’s Bazar un-broken sea beaches were the apt symbol. Aryans, Turks, Mughals, Afghans, Arabs, Dutch, Portuguese, French and British were attracted by the opulence of Bengal. They came as invaders, traders, settlers, missionaries and in their different ways, contributed towards making this country a distinctive entity among the world’s nations, boasting numerous historical and natural assets. However, this is kaleidoscopic presentation of our land called coastal belt in Bangladesh, its valiant people imbued with a sense of history, its rich and flora and fauna, its verdant landscape with lush green fields, enchanting hills and hillocks and the meandering rivers falling into the vast blue expanse of the Bay of Bengal. It is a land of enormous economic potentials, inhabited by diligent and hard-working people who have a love for heritage. It is a land of ancient and variegated religious and cultural traditions. All of these together make Sundarbans a colorful mosaic of nature’s splendor and bounty (Awal, 2014). Despite various hypotheses as to the causes of this natural degradation, the underlying causes are still not well understood. The present work has explored some of the possible factors involved, focusing particularly on the relationship among the environmental factors and the human destruction of Sundarbans ecosystem as well as abnormal concentrations of a number of chemical elements present in the soil, in order to test the hypothesis that ecological pollution, along with chemical pollution might be responsible. However, the present results have showed that Sn, Exchangeable K, soil pH, Pb , Zn and Ni could be directly linked with top-dying disease of Heritiera fomes (Sundri) in Sundarbans, probably particularly by weakening the vigor of the trees and people and allowing other factors such as pathological agents to attack the plants and surrounding people in Sundarbans, Bangladesh (Awal, 2014). In fact, from since then and still now, the natural resource of Bangladesh like Sundarbans is being disturbed ecologically by human destruction.
