The goals of the Bachelor of Environmental Science Degree are to: Offer a rigorous

science-based preparation for careers in environmental science; Prepare students for

graduate studies in environmental science. Environmental Sciences is a kind of

subject where only theoretical lessons cannot provide hundred percent of

knowledge. The earth is a mysterious planet and to gain knowledge about the earth,

visual observation through tour is must. Environmental science is the scientific

investigation of human interactions with natural systems. The department of

environmental sciences of Jahangirnagar University runs a course on field work as

an academic study course each year. For the students of Environmental Sciences,

field work is a part and parcel of academic study. It plays a very significant role in

understanding complicated environmental concepts and their impact on biodiversity

and sustainability. To evaluate the natural and artificial processes of the study areas

and finding it’s role on environment. As a student of 2nd year of environmental

sciences of Jahangirnagar University in the session 2011-2012 carried out a field

work for 5 days from 5th February 2014 to 9th February 2014 in Saint Martin,

Maheshkhali and Cox’s bazar. St. Martin’s Island the only coral reef of Bangladesh,

has enormous geological and biological resources to identify, understand and need

to protect from anthropogenic and non-anthropogenic threats. As an ecologically

critical area (ECA), it needs more study to gather knowledge about these beautiful

sites. Heavy minerals along the coastline are an excellent source of so called ‘Black Gold’ of Bangladesh. Maheshkhali is important for the salt farming. The area is important from the geological and economical point of view. Cox's Bazar is a seaside

town, a fishing port and district headquarters in Bangladesh. It is known for its wide

and long sandy beach, which is considered by many as the world's longest natural

sandy sea beach.
