Life originated in the ocean and moved onto earth!
The biosphere of the earth is sustained due to the constant and consistent interactions between atmosphere, lithosphere and hydrosphere. This is a process which has continued for 4 billion years.
Through these interactions, nature sculptured and continued to mould the landscapes and seascapes on which human beings have carved out various niches for livelihood and habitation. The modern global, advanced technology-driven interventions considerably modified these niches, both at land, sea and the interfaces. Perhaps one such important interface, and a highly dynamic one at that, is what we popularly call the coastal zone.
