save the coastal and tidal flats

most of the coastal habitats especially tidal flats are submerged. Because there is no proper monitoring facilities and stipulated methdology adopted to protect the shore line. The main problem is pollution very particularly oil spills, sepage and sewages and anthropogenic pressures throughcoastal areas people practices. On the other hand the freshwater runn off  being pollute the coastal areas and tidal flats. So, the food chain and food webs are affected. The important factor is migratory birds are affected by these impacts. So,Still we need lot of awarness and proper methedology to protect the nature, unless very soon all the coastal areas will be vanished. Otherwise globally the migratory stop over sites and benthic organism production will be fragmented.
