Tourism fishing and navigationare also responsible, for destroying these resources. Illicit quarrying of buried corals . and shells in the interior is also done on a large scale for production of lime and chicken grit. This con tinued destruction of valuable resources has created a number of ecological and socio-economic problems. This paper focuses atten tion on such problems and emphasizes the need for manage ment of these resources with a view to protecting the natural herit age as well as to providing a means of livehood to those engaged in these activities.

It is revealed that Gondwanaland emerged between the Huronian glaciation (2100-2400 Ma) in the Paleoproterozoic Era and the Andean-Saharan glaciation (420-450 Ma) in the Early Paleozoic Era. During this time, most continental land masses were clustered in the southern hemisphere, and the landmass of Sri Lanka remained joined to Africa-Madagascar and India to Antarctica. Within the Ordovician (488.3-445.6 Ma) to Permian (299.0-253.8 Ma) periods there were signs of the breaking up of Gondwanaland, and Sri Lanka and India were positioned within it. By the end of the Permian Period (260 Ma) Karoo Glaciation had ended and the present Mannar Basin developed within a deep canyon (about 4 km deep) on the Precambrian basement. Although the present island of Sri Lanka lies in the Indian Ocean between 5 º 52´N-9 º 54´N and 79 º 30´E-81 º 55´E, to the southwest of...
