Popular articles. Runoff from agriculture and industry in New York and New Jersey also contributed a toxic estuarine environment.
Industrial waste and pesticide s travel downstream and settle in the water and sediment of the estuary. Today, strict regulations and community activities are working to protect and restore the Hudson-Raritan Estuary.
The restoration of oyster beds is an important part of many projects. Oysters are a keystone species in the estuary, filter feeder s that naturally help regulate toxins in the water. Millions of oyster beds greeted Henry Hudson when he entered the river in By the middle of the 20th century, however, the few remaining oysters were too toxic for human consumption. Today, several environmental groups are establishing oyster beds to repopulate the region's native species and reduce pollution in the estuary.
Overfishing Many estuaries have been overfish ed. Pacific bluefin tuna are not endangered, but their range has been drastically reduced. Japan provides one of the largest markets for bluefin tuna, and the fish used to swim in the estuary of Tokyo Bay.
Bluefin tuna are large, predatory fish. They require an expansive habitat and many kilograms of food every day. As Tokyo's population grew and technology made it easier to catch more fish with less time and money, Tokyo Bay's bluefin tuna population shrank.
Today, there is not a bluefin tuna population in Tokyo Bay. However, Japanese scientists have established a successful tuna fish farming technique. Farm-raised tuna does not have a direct environmental impact on the Tokyo Bay estuary.
Indonesian, American, and Japanese governments and environmental groups struggle to promote sustainable development in estuaries. Sustainable development aims to preserve the environment while satisfying people's economic standard of living.
Edo Tokyo, the most populous city in the world, was originally known as Edo, which means "estuary. Largest Estuary in the World Because the definition of "estuary" is fluid, determining which one is the world's largest is an ongoing debate. However, many scientists say that that St. Lawrence River, which connects the Great Lakes to the Atlantic Ocean, is the world's largest estuary. The St. Lawrence River is about 1, kilometers miles long. Between Land Some Native Americans called estuaries the "Between-Land" because they are not quite land and not quite water.
Also called an alpha predator or top predator. Hurricanes are the same thing as typhoons, but usually located in the Atlantic Ocean region. The last ice age peaked about 20, years ago. Also called glacial age.
Usually rivers enter another body of water at their mouths. Pesticides can be fungicides which kill harmful fungi , insecticides which kill harmful insects , herbicides which kill harmful plants , or rodenticides which kill harmful rodents. Also called an autotroph. Also called a storm tide.

Common freshwater wetlands can include marshes and swamps, and are typical of the upper Sacramento—San Joaquin River Delta. Another type of wetland habitat is riparian habitat, which is found along streams and lakes and typically supports verdant stands of water-loving plants. In all these kinds of wetlands, submerged and partially submerged vegetation provide food and refuge for a myriad of species, and also capture sediment and pollutants. Land development has claimed much of the wetland habitat in the Bay Area, but a number of restoration projects, including those spearheaded by the National Park Service and its partners at Crissy Field, Drakes Estero, Muir Beach, and the Giacomini and Banducci farms, are attempting to reverse that trend.
