. The early "Big Game Hunters" vanished, but the coastal regions were resettled by peoples accustomed to village-style living ("tidewater communities") that subsisted on hunting and gathering marine shellfish, and eventually, on agriculture. In pre-Columbian times "woodlands cultures" probably centered in the Ohio Valley became the dominant cultural influence in the region. Large shell middens were found around Raritan Bay and on Staten Island, a testament of the utilization of the bay for food by Algonquin Indian tribes (Lenapes) who occupied the area when early Colonialists arrived. Early settlers used these shell piles for road construction and field fertilizer. Tottenville was once well known for its roads paved with oyster shells.Geologic History of Raritan Bay

This rise in sea level has resulted in the landward migration of the shoreline (aided by storm-induced

, which helped to support a stable population around the bay and aided, in part, to feed the flood of immigration. Stable communities continued to grow and change with new industries supporting a larger population base. Advances in methods of fishing and shellfish collecting resulted in overextraction of these resources from the bay. The peak of the fishing industry occurred in the late 1880s to 1910s. Fishing and farming slowly gave way to industries including ship building, ceramics, chemicals and paint manufacturing, electrolytic copper refining, and petroleum refining. In the Keasbey, New Jersey area, large pits were dug to extract the clays for ceramics and bricks, and huge chemical dumps,

For most of the 20th century, the shores of Arthur Kill have been home to the largest petroleum importing, refining, and storage facilities on Earth; as a consequence the estuary has been host to major and minor oil spills. In addition, Arthur Kill drains the area encompassing the second largest landfill on Earth ( Fresh Kills Landfill). This landfill, and others along the Raritan River, provide an ample supply of

to the waterways. Chemical wastes cause stress and disruption of the life cycles of plankton, shellfish and other invertebrates, and the fish, birds, and other wildlife that they support. The result was an ecological disaster. The bay approached sterile conditions at the peak of pollution and algal bloom-induced anoxia. Environmental actions from the 1970s to present have helped slowly bring back sea life, but current conditions pale to the wealth of marine resources of the past; certain species of fish and birds continue to decline, and the introduction of tenacious exotic species from around the world contribute to their decline. As a sign of optimism though, oysters are beginning to naturally reappear in the Hudson River after having vanished completely about the time of
