Periodic mass dieoffs result in vast numbers of the fish washing up on shore; estimates by various governments have placed the percentage of Lake Michigan's biomass, which was made up of alewives in the early 1960s, as high as 90%. Try birdwatching. According to the bi-national (U.S. and Canadian) resource book, The Great Lakes: An Environmental Atlas and Resource Book: "The largest Great Lakes fish harvests were recorded in 1889 and 1899 at some 67,000 tonnes (66,000 long tons; 74,000 short tons) [147 million pounds].  The lakes themselves also have a moderating effect on the climate; they can also increase precipitation totals and produce lake effect snowfall.. Pleasure boats can also enter or exit the Great Lakes by way of the Erie Canal and Hudson River in New York. [clarification needed], Overfishing has been cited as a possible reason for a decrease in population of various whitefish, important because of their culinary desirability and, hence, economic consequence. Native habitats and ecoregions in the Great Lakes region include: Logging of the extensive forests in the Great Lakes region removed riparian and adjacent tree cover over rivers and streams, which provide shade, moderating water temperatures in fish spawning grounds. Algae such as diatoms, along with other phytoplankton, are photosynthetic primary producers supporting the food web of the Great Lakes, and have been effected by global warming. A few more interesting facts: One such merchant was John P. Clark, a shipbuilder and merchant who began selling fish in the area of Manitowoc, Wisconsin where whitefish was abundant. By Anonymous 1 hour, 51 minutes ago. Since general freight these days is transported by railroads and trucks, domestic ships mostly move bulk cargoes, such as iron ore, coal and limestone for the steel industry.  Invasive species, particularly zebra and quagga mussels, may be at least partially responsible for the collapse of the deepwater demersal fish community in Lake Huron, as well as drastic unprecedented changes in the zooplankton community of the lake. Only four bridges are on the Great Lakes other than Lake Ontario because of the cost of building structures high enough for ships to pass under. Historically, the Great Lakes, in addition to their lake ecology, were surrounded by various forest ecoregions (except in a relatively small area of southeast Lake Michigan where savanna or prairie occasionally intruded). , Several Native American populations (Paleo-indians) inhabited the region around 10,000 BC, after the end of the Wisconsin glaciation. The Great Lakes Water Quality Agreement, signed in 1972 and renewed in 2012, commits Canada and the United States to restore and maintain the chemical, physical and biological integrity of the Great Lakes ecosystem. Dunbar. Major ports on the Great Lakes include Duluth-Superior, Chicago, Detroit, Cleveland, Twin Harbors, Hamilton and Thunder Bay. Millions of hawks, … Doty, ship that sank in Lake Michigan 112 years ago, found largely intact near Milwaukee", "Federal Statute on Great Lakes. GREAT LAKES. 907-262-7949. Call or email us today so we can help answer your questions. Hundreds of ships have met their end on the lakes. The influx of parasitic lamprey populations after the development of the Erie Canal and the much later Welland Canal led to the two federal governments of the US and Canada working on joint proposals to control it. In 1872, a treaty gave access to the St. Lawrence River to the United States, and access to Lake Michigan to the Dominion of Canada. Sport fishing, commercial fishing, and Native American fishing represent a U.S.$4 billion a year industry with salmon, whitefish, smelt, lake trout, bass and walleye being major catches. Particularly, the 1825 opening of the Erie Canal and the Welland Canal a few years later. , The Great Lakes are an important source of fishing. The area of each rectangle is proportionate to the volume of each lake. Both the province of Ontario and the state of Michigan include in their boundaries portions of four of the lakes: The province of Ontario does not border Lake Michigan, and the state of Michigan does not border Lake Ontario. 1. , The physical impacts of climate change can be seen in water levels in the Great Lakes over the past century. Mercury compounds have been used in paper mills to prevent slime from forming during their production, and chemical companies have used mercury to separate chlorine from brine solutions. Snow belts are found in Wisconsin, Michigan, Ohio, Pennsylvania, and New York, United States; and Ontario, Canada. Local sewage treatment authorities then must release untreated effluent, a mix of rainwater and sewage, into local water bodies. They protect against frost during transitional weather, and keep the summertime temperatures cooler than further inland. Annually, only about 1% is "new" water originating from rivers, precipitation, and groundwater springs that drain into the lakes. Because the lakes are great. Although Lake Baikal in Russia has a larger volume of water, the combined area of the Great Lakes—some 94,250 square miles (244,106 square kilometres)—represents the … This page was last edited on 24 December 2020, at 21:12. , The Great Lakes coast measures approximately 10,500 miles (16,900 km);, but the length of a coastline is impossible to measure exactly and is not a well-defined measure (see Coastline paradox).  Since the glaciers covered some areas longer than others, this glacial rebound occurred at different rates. Great Lakes Gelatin Company’s Gelatin products are the finest available.  Lake Champlain briefly became the sixth Great Lake of the United States on March 6, 1998, when President Clinton signed Senate Bill 927.  The total surface is 94,250 square miles (244,106 km2), and the total volume (measured at the low water datum) is 5,439 cubic miles (22,671 km3), slightly less than the volume of Lake Baikal (5,666 cu mi or 23,615 km3, 22–23% of the world's surface fresh water). Doty was found in Lake Michigan by an exploration diving team led by dive boat Captain Jitka Hanakova from her boat the Molly V. The ship sank in October 1898, probably attempting to rescue a small schooner, Olive Jeanette, during a terrible storm. Posted on April 22, 2012 by Hurricane River Publishing. These fast-growing planktivorous fish have heavily colonized the Mississippi and Illinois river systems.  Reports about this issue on the U.S. side highlight five large municipal systems (those of Detroit, Cleveland, Buffalo, Milwaukee and Gary) as being the largest current periodic sources of untreated discharges into the Great Lakes.. Lake Huron was the first of the Great Lakes to be discovered by Europeans. Land below the glaciers "rebounded" as it was uncovered. This is a laker with a conveyor belt system that can unload itself by swinging a crane over the side. Moreover, between 1879 and 1899, reported whitefish harvests declined from some 24.3 million pounds (11 million kg) to just over 9 million pounds (4 million kg). While the organisms living on the bottom of shallow waters are similar to those found in smaller lakes, the deep waters contain organisms found only in deep, cold lakes of the northern latitudes. The ships also have a distinctive design (see Lake freighter). ", By 1801, the New York Legislature found it necessary to pass regulations curtailing obstructions to the natural migrations of Atlantic salmon from Lake Erie into their spawning channels. Fish and Wildlife Service estimates that the economic impact of the zebra mussel could be about $5 billion over the next decade. , On both sides of the Canada–United States border, the proliferation of dams and impoundments have multiplied, necessitating more regulatory efforts.  In 2013, record low water levels in the Great Lakes were attributed to climate change. The Great Lakes Waterway connects all the lakes; the smaller Saint Lawrence Seaway connects the lakes to the Atlantic oceans.  The lakes have been a major source for transportation, migration, trade, and fishing, serving as a habitat to many aquatic species in a region with much biodiversity. The Great Lakes are used to supply drinking water to tens of millions of people in bordering areas. Other protective legislation was passed, as well, but enforcement remained difficult. The Great Lakes began to form at the end of the last glacial period around 14,000 years ago, as retreating ice sheets exposed the basins they had carved into the land, which then filled with meltwater.  The largest among them is Manitoulin Island in Lake Huron, the largest island in any inland body of water in the world.  Both of these islands are large enough to contain multiple lakes themselves—for instance, Manitoulin Island's Lake Manitou is the world's largest lake on a freshwater island. , Since the 19th century an estimated 160 new species have found their way into the Great Lakes ecosystem; many have become invasive; the overseas ship ballast and ship hull parasitism are causing severe economic and ecological impacts. This corresponds to thinking of lakes Erie and Ontario as "down south" and the others as "up north".  The ruffe, a small percid fish from Eurasia, became the most abundant fish species in Lake Superior's Saint Louis River within five years of its detection in 1986. Yes, the Great Lakes are all connected. The largest and last major freighter wrecked on the lakes was the SS Edmund Fitzgerald, which sank on November 10, 1975, just over 17 miles (30 km) offshore from Whitefish Point on Lake Superior. Mercury has been known for health related problems such as birth defects in humans and animals, and the near extinction of eagles in the Great Lakes region. Köppen climate classification Dfa (in southern areas) and Dfb (in northern parts) with varying influences from air masses from other regions including dry, cold Arctic systems, mild Pacific air masses from the West, and warm, wet tropical systems from the south and the Gulf of Mexico. The Rush–Bagot Treaty signed in 1818, after the War of 1812 and the later Treaty of Washington eventually led to a complete disarmament of naval vessels in the Great Lakes. International treaties regulate large diversions. , The Great Lakes have a humid continental climate, , The water level of Lake Michigan–Huron had remained fairly constant over the 20th century, but has nevertheless dropped more than 6 feet from the record high in 1986 to the low of 2013. By the 1960s, the small silver fish had become a familiar nuisance to beach goers across Lakes Michigan, Huron, and Erie. The Great Lakes basin accumulates a significant portion of the planet’s fresh water, and the entire vast ecosystem is a critical bellwether for troubling changes worldwide. From the interior to the outlet at the Saint Lawrence River, water flows from Superior to Huron and Michigan, southward to Erie, and finally northward to Lake Ontario. The lakes are prone to sudden and severe storms, in particular in the autumn, from late October until early December. When I first moved to Florida from Northern Michigan, I started having a Great Lakes withdrawal every year. Still missing are the two last warships to sink in the Great Lakes, the French minesweepers, Inkerman and Cerisoles, which vanished in Lake Superior during a blizzard in 1918. Several species of crayfish have also been introduced that may contend with native crayfish populations. Caught in a 1679 storm while trading furs between Green Bay and Michilimacinac, she was lost with all hands aboard. Hastings, D. and P.K.  The peoples of the Great Lakes traded with the Hopewell culture from around 1000 AD, as copper nuggets have been extracted from the region, and fashioned into ornaments and weapons in the mounds of Southern Ohio. Handcrafted duck and goose calls using exotic & domestic woods, & acrylics. This protein is fully digestible and contains 19 different amino acids. When a second fault line, the Saint Lawrence rift, formed approximately 570 million years ago, the basis for Lakes Ontario and Erie were created, along with what would become the Saint Lawrence River. Federal and state regulations control substances like PCBs. All measurements at Low Water Datum. This bill, which reauthorized the National Sea Grant Program, contained a line declaring Lake Champlain to be a Great Lake. In 2009, the lakes contained 84% of the surface freshwater of North America; if the water were evenly distributed over the entire continent's land area, it would reach a depth of 5 feet (1.5 meters). Even late in winter, the lakes often have no icepack in the middle. Implementation of secondary treatment of municipal sewage by major cities greatly reduced the routine discharge of untreated sewage during the 1970s and 1980s.  The second-largest island is Isle Royale in Lake Superior. … and the lakes are changing, in ways that are difficult to predict, and that should concern all of us who love and depend on this vital heritage. Commercial tug-and-barge traffic on these waterways is heavy.. The five Great Lakes have borders with eight U.S. states—Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin—and one … The entire crew of 23 drowned, except one, Charles Pitz, who floated on a life raft for almost seven hours.. The main business of many of the passenger lines in the 19th century was transporting immigrants.  This was followed by record high levels in all lakes except Ontario in the late 2010s and 2020. The lake's surface area is 23,000 square miles (59,600 square kilometers) and its volume is 850 cubic miles (3,540 cubic km). Since the late 19th century, lakers have carried bulk cargoes of materials such as limestone, iron ore, grain, coal, or salt from the mines and fields of the upper Great Lakes to the populous industrial areas farther east. The goby is considered undesirable for several reasons: it preys upon bottom-feeding fish, overruns optimal habitat, spawns multiple times a season, and can survive poor water quality conditions. Create a free website or blog at WordPress.com. Change ), You are commenting using your Google account. One of the more common sights on the lakes has been since about 1950 the 1,000‑by‑105-foot (305-by-32-meter), 78,850-long-ton (80,120-metric-ton) self-unloader.  At least two human water use activities have been identified as having the potential to affect the lakes' levels: diversion (the transfer of water to other watersheds) and consumption (substantially done today by the use of lake water to power and cool electric generation plants, resulting in evaporation). This is a result of significant expenditures to date on both infrastructure and technology, and robust regulatory systems that have proven to be, on the whole, quite effective. Logging, urbanization, and agriculture uses have changed that relationship. Many of the larger cities owe their existence to their position on the lakes as a freight destination as well as for being a magnet for immigrants.  Throughout history, fish populations were the early indicator of the condition of the Lakes and have remained one of the key indicators even in the current era of sophisticated analyses and measuring instruments. This is enough water to cover the 48 contiguous U.S. states to a uniform depth of 9.5 feet (2.9 m). , The Great Lakes contain 21% of the world's surface fresh water: 5,472 cubic miles (22,810 km3), or 6.0×1015 U.S. gallons, that is 6 quadrillion U.S gallons, (2.3×1016 liters). 62, Iss.  With these two canals an all-inland water route was provided between New York City and New Orleans. Lake Huron is the only Great Lake bordered by one state, Michigan. In the early 21st century, Lake Superior's shores are 91% forested, Lake Huron 68%, Lake Ontario 49%, Lake Michigan 41%, and Lake Erie, where logging and urbanization has been most extensive, 21%. The Blue Water Bridge is, for example, more than 150 feet high and more than a mile long.. Concerns by the mid-19th century included obstructions in the rivers which prevented salmon and lake sturgeon from reaching their spawning grounds. Historically, evaporation has been balanced by drainage, making the level of the lakes constant. No one of the Lakes is larger than Lake Baikal or Lake Tanganyika (East Africa).. As the slightly warmer, moist air passes over the colder land surface, the moisture often produces concentrated, heavy snowfall that sets up in bands or "streamers". Photosynthesis carried out by diatoms comprises about one fifth of the total photosynthesis. Great Lakes Calling. I can not find campbell's Tomato Garden soup anywhere.  Some of these lakes even have their own islands, like Treasure Island in Lake Mindemoya in Manitoulin Island.  In 2009, it was predicted that global warming will decrease water levels. In 1996 a rare tropical or subtropical storm was observed forming in Lake Huron, dubbed the 1996 Lake Huron cyclone. "Evolution of the Great Lakes Water Quality Agreement", Paul Muldoon and Lee Botts, Michigan State University Press, 2005, Burkhardt Steffen, Amoroso Gabi, Riebesell Ulf, Sültemeyer Dieter, (2001), CO. Brian N. Popp, Edward A. Call Us. Of the total 10,500 miles (16,900 km) of shoreline, Canada borders approximately 5,200 miles (8,400 km), while the remaining 5,300 miles (8,500 km) are bordered by the United States. The agreements strengthen protection against abusive water withdrawal practices within the Great Lakes basin. Although a drop of lake water may contain 1 million bacteria cells and 10 million viruses, only since 2012 has there been a long-term study of the lakes' micro-organisms. " The commission reported that all urban sewage treatment systems on the U.S. side of the lakes had implemented secondary treatment, as had all on the Canadian side except for five small systems. New York and Wisconsin's jurisdictions extend into two lakes, and each of the remaining states into one of the lakes. Map: The Great Lakes Drainage Basin A map shows the five Great Lakes (Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario), and their locations between two countries - Canada and the United States (US). Some icebreakers ply the lakes, keeping the shipping lanes open through other periods of ice on the lakes. A similar phenomenon allows wineries to flourish in the Finger Lakes region of New York, as well as in Prince Edward County, Ontario on Lake Ontario's northeast shore. , Scientists understand that the micro-aquatic life of the lakes is abundant, but know very little about some of the most plentiful microbes and their environmental effects in the Great Lakes. It is some 300 miles (500 km) long and 30 to 140 miles An alternate track is via the Illinois River (from Chicago), to the Mississippi, up the Ohio, and then through the Tennessee–Tombigbee Waterway (a combination of a series of rivers and lakes and canals), to Mobile Bay and the Gulf of Mexico. The Great Lakes Circle Tour is a designated scenic road system connecting all of the Great Lakes and the Saint Lawrence River.. , Though contrary to federal laws in both countries, those treatment system upgrades have not yet eliminated Combined sewer Overflow events.  Yet in 2019–2020 lake levels on Lake Michigan-Huron had again returned to record high levels. Some lake freighters are too large to use the Seaway, and operate only on the Waterway and lakes.  The retreat of the ice sheet left behind a large amount of meltwater (see Lake Algonquin, Lake Chicago, Glacial Lake Iroquois, and Champlain Sea) that filled up the basins that the glaciers had carved, thus creating the Great Lakes as we know them today. These vessels are traditionally called boats, although classified as ships.. Only barges can access the Illinois Waterway system providing access to the Gulf of Mexico via the Mississippi River. More recently an electric fence has been set up across the Chicago Sanitary and Ship Canal in order to keep several species of invasive Asian carp out of the area. 78 lives were lost making it the largest loss of life in Lake Superior and the greatest unexplained loss of life in the Great Lakes. Some water is diverted through the Chicago River to operate the Illinois Waterway but the flow is limited by treaty.  Because of the uneven nature of glacier erosion, some higher hills became Great Lakes islands. 1 talking about this. Ships that primarily trade on the lakes are known as lakers.  By 1848, with the opening of the Illinois and Michigan Canal at Chicago, direct access to the Mississippi River was possible from the lakes. This gigantic lake contains 10 percent of all the world's fresh surface water. Possible schemes for bottled water plants and diversion to dry regions of the continent raise concerns. Due to their sea-like characteristics (rolling waves, sustained winds, strong currents, great depths, and distant horizons) the five Great Lakes have long been called inland seas. In 1831, Alexander MacGregor from Goderich, Ontario found whitefish and herring in unusually abundant supply around the Fishing Islands. The shoreline is 3,827 miles (6,157 km), taking into account its many islands, according to the Environmental Protection Agency (EPA). Great Slave Lake, lake, in southern Northwest Territories, Canada, near the Alberta border. An organization representing more than 100 cities in Canada and the U.S. is calling for steps to deal with the recently discovered problem of "microplastic" pollution in the Great Lakes.  The changes in the size or in the function of the primary producers may have a direct or an indirect impact on the food web. This is most noticeable along Lake Superior's shores. Some of these forests are second or third growth (i.e. , Until 1970, mercury was not listed as a harmful chemical, according to the United States Federal Water Quality Administration. After railroads and surface roads developed, the freight and passenger businesses dwindled and, except for ferries and a few foreign cruise ships, have now vanished. The names of the great lakes are: The Superior,Huron, Erie, Michigan, and Ontario. They are lakes Superior, Michigan, Huron, Erie, and Ontario. Between 2012 and 2019 more than 160 new species have been discovered..  Presque Isle Bay in Pennsylvania is formally listed as in recovery, as is Ontario's Spanish Harbour. Global Land One-kilometer Base Elevation (GLOBE) v. 1. , Blue-green algae, or Cyanobacteria blooms, have been problematic on Lake Erie since 2011. National Geophysical Data Center (1999). By the mid-1980s, most jurisdictions bordering the Great Lakes had controlled phosphate detergents, resulting in sharp reductions in the frequency and extent of the blooms.  In the first half of the 20th century large luxurious passenger steamers sailed the lakes in opulence. The greatest concentration of shipwrecks lies near Thunder Bay (Michigan), beneath Lake Huron, near the point where eastbound and westbound shipping lanes converge. For instance, Western Michigan has apple and cherry orchards, and vineyards cultivated adjacent to the lake shore as far north as the Grand Traverse Bay and Nottawasaga Bay in central Ontario. , Several species of exotic water fleas have accidentally been introduced into the Great Lakes, such as the spiny waterflea, Bythotrephes longimanus, and the fishhook waterflea, Cercopagis pengoi, potentially having an effect on the zooplankton population. , The alewife first entered the system west of Lake Ontario via 19th-century canals. Great Lakes, chain of deep freshwater lakes in east-central North America comprising Lakes Superior, Michigan, Huron, Erie, and Ontario. Not coincidentally, this status allows neighboring states to apply for additional federal research and education funds allocated to these national resources. In general, they are on or near the Canada–United States border. Michigan has the longest shoreline of the United States, bordering roughly 3,288 miles (5,292 km) of shoreline, followed by Wisconsin (820 miles (1,320 km)), New York (473 miles (761 km)), and Ohio (312 miles (502 km)).  The International Joint Commission in 2009 summarized the change: "Since the early 1970s, the level of treatment to reduce pollution from waste water discharges to the Great Lakes has improved considerably. Change ), You are commenting using your Facebook account. Another operation cropped up in Georgian Bay, Canadian waters plentiful with trout as well as whitefish. Public outcry forced the company to abandon the plan before it began. This summer, for several reasons, I’ve elected to spend my vacation in the Smokey Mountains.  Several ferries currently operate on the Great Lakes to carry passengers to various islands, including Isle Royale, Drummond Island, Pelee Island, Mackinac Island, Beaver Island, Bois Blanc Island (Ontario), Bois Blanc Island (Michigan), Kelleys Island, South Bass Island, North Manitou Island, South Manitou Island, Harsens Island, Manitoulin Island, and the Toronto Islands. They are one of the great natural features of the continent and of the Earth.  Researchers at the Mowat Centre said that low levels could cost $19bn by 2050.  The United Nations' Intergovernmental Panel on Climate Change in 1997 predicted: "the following lake level declines could occur: Lake Superior −0.2 to −0.5 m, Lakes Michigan and Huron −1.0 to −2.5 m, and Lake Erie −0.9 to −1.9 m".  This describes when older sewerage systems, which combine storm water with sewage into single sewers heading to the treatment plant, are temporarily overwhelmed by heavy rainstorms. Studies conducted by the Environmental Protection Agency have shown that when the mercury comes in contact with many of the bacteria and compounds in the fresh water, it forms the compound methyl mercury, which has a much greater impact on human health than elemental mercury due to a higher propensity for absorption. The mollusks are efficient filter feeders, competing with native mussels and reducing available food and spawning grounds for fish. National Geophysical Data Center, NOAA. Even though I lived in Ft. Lauderdale at the time and had access to the ocean whenever I wanted, it just wasn’t the same as Lake Michigan. Already I can feel the Great Lakes starting to pull me in their direction.  Discharge of toxic substances has been sharply reduced. More vessels have been lost in the Whitefish Point area than any other part of Lake Superior. Removal of trees also destabilized the soil, with greater volumes washed into stream beds causing siltation of gravel beds, and more frequent flooding. When the sailing ships gave way to steamships, they were called steamboats—the same term used on the Mississippi. As of 2007, four car ferry services cross the Great Lakes, two on Lake Michigan: a steamer from Ludington, Michigan, to Manitowoc, Wisconsin, and a high speed catamaran from Milwaukee to Muskegon, Michigan, one on Lake Erie: a boat from Kingsville, Ontario, or Leamington, Ontario, to Pelee Island, Ontario, then onto Sandusky, Ohio, and one on Lake Huron: the M.S. While enormous public investments such as the Deep Tunnel projects in Chicago and Milwaukee have greatly reduced the frequency and volume of these events, they have not been eliminated. By taking CO2 out of the water, to photosynthesize, diatoms help to stabilize the pH of the water, as otherwise CO2 would react with water making it more acidic. Barges from middle North America were able to reach the Atlantic Ocean from the Great Lakes when the Welland canal opened in 1824 and the later Erie Canal opened in 1825. , Alan B. McCullough has written that the fishing industry of the Great Lakes got its start "on the American side of Lake Ontario in Chaumont Bay, near the Maumee River on Lake Erie, and on the Detroit River at about the time of the War of 1812". The Great Lakes basin supports a diverse, globally significant ecosystem that is essential to the resource value and sustainability of the region. 19. ", https://www.glerl.noaa.gov/data/wlevels/data/miHuronLevelsFeet.png, "Genesee, Oakland counties adopt historic name for water group", "Origin and evolution of the Great Lakes", "Lake levels report weighs Great Lakes basin's glacial legacy", "Ice Volcanoes of the Lake Erie Shore Near Dunkirk, New York, U.S.A.", "Great Lakes Water Levels Sensitive To Climate Change", "Gobies up, alewives down in Lake Michigan", "Predicting Invasive Species in the Great Lakes", "Briefing Paper: Great Lakes Nonindigenous Invasive Species", "Risk Assessment for Asian Carps in Canada", "Deepwater demersal fish community collapse in Lake Huron", "Minuscule microbes wield enormous power over the Great Lakes. The largest loss of life in a shipwreck out on the lakes may have been that of Lady Elgin, wrecked in 1860 with the loss of around 400 lives on Lake Michigan. The Great Lakes are also connected by the Chicago Sanitary and Ship Canal to the Gulf of Mexico by way of the Illinois River (from the Chicago River) and the Mississippi River. It will require the Ontario government to set science-based targets and develop action plans to address the most severe threats to the Great Lakes, such as habitat loss, the influx of invasive species, and mounting toxic pollutants. *** Our premium gelatin, made of ONE simple ingredient, provides you with exceptional cooking functionality at a fair price.
