Abstract
Among the natural resources, biodiversity holds a tremendous character in the economic development of Bangladesh. Besides keeping the air breathable, biodiversity works for Bangladesh with food, water supply, medicines, clothes and shelters. It is very hard to realize and calculate the benefactions of biodiversity upon the economy of Bangladesh. This highly advantageous biodiversity is under a serious threat. Loss of biodiversity may have cyclic aftermaths on ecosystems because of the multiplex affinity among species. For example, extinction of one species may cause the extinction of another. To measure biodiversity loss, scientists assess which species are at risk of extinction as well as survey ecosystem decline. Man made squeeze, unlimited dredging, hydrological interference, contamination; chemical fertilizers are causing the detrimental effects on habitat, biodiversity as well as on sinkhole. Over-exploitation, deforestation, habitat change to agriculture, pollution, and interfering species are being considered the most important current operators of biodiversity loss in Bangladesh. To conserve habitats and biodiversity, to promote sustainable development and to improve qualitative indexes of human life, many national laws have been adopted at national levels over the world. In this journey, Bangladesh recognizes the indispensable significance of engaging in global attempts to halt the causes of humiliation of biological diversity. The international and legal regime covering climate change is also administered by the Convention to regulate International Trade in Endangered Species of Flora and Fauna (CITES) to some extent. Till to date, there is no direct legislation in relation to climate change and its adverse effect on biodiversity. This paper is a venture to analyze the implementation of concerning international and municipal legal instruments. The reasons of fatigue of biodiversity and the repercussions on ecosystem amenity and relating laws are also examined in this study. The specific aim of this Paper is to find out the menace on biological diversity, causes and consequences of loss of Biological diversity in Bangladesh. Finally, author will make some recommendations to materialize the legal segments concerning the issue.
