Learning Outcomes By the end of the lesson, students will be able to: Use different types of maps (e.g. road, topographical, thematic) to interpret geographic relationships, including changes over time in a specific location explain how human activities (e.g. agricultural and urban development, waste management, parks development, forest harvesting, land reclamation) affect, or are affected by, the environment identify the role of government in managing resources and protecting the environment assess how the effects of urban growth (e.g. development on former farm lands, destruction of wildlife habitats, draining of marshes) alter the natural environment present findings from research on ways of improving the balance between human and natural systems (e.g. recycling, river clean-ups, ecological restoration of local woodlots or schoolyards, industrial initiatives to reduce pollution) explain how selected factors cause change in human and natural systems (e.g. technological developments, corporate and government policies, zoning by-laws, natural hazards, global warming) gather geographic information from primary sources (e.g. field research, surveys, interviews) and secondary sources (e.g. reference books, mainstream and alternative media, CD-ROMs, the Internet) to research a geographic issue

Teacher Activity Student Activity Lesson Create a line graph showing changes in Development the Beluga population since 1977. (cont’d) Identify the issues of pollution, disease, human disturbances that harm them and actions taken to preserve and protect them. Conclusion Discuss the status of the Beluga Students contribute to the class population with students. Note that our discussion. individual environmental decisions can have significant impacts on them or on other threatened or endangered species.
Lesson Extension Students can investigate the distribution and status of other threatened or endangered species in Canada. Polar bears, for instance, provide a convenient tie-in with the issue of global warming.
Assessment of Student Learning The teacher may collect one or both of the worksheets. The information may be included on a unit test.

Activity Source of the St. Lawrence is Lake
Mouth: (A gulf is an arm of a sea or ocean partly enclosed by land; yet larger
than a bay)
Direction of flow:
Length: kilometres to the head of St. Louis River, Minnesota, USA
Origin of name: on St. Lawrence’s Day in 1535, explorer gave the Saint’s
name to a bay at the river’s mouth; in the early 1600s, it was adopted for the entire river. The Mohawk name is
Kaniatarowanenneh, meaning “ ”
Fed by Lake Ontario, Canada’s “great river” drains about million square
kilometers. The St. Lawrence is framed by the Highlands to the north and the
Mountains to the south. It starts out as a freshwater waterway from just east of
, Ont., and forms the border with the United States to Cornwall, Ont. It then broadens into a number
of lakes on its way to Montréal.
From Trois-Rivières to Québec, the freshwater flow is with the tides. The
riverbed drops dramatically at the mouth of the River, where fresh water mixes
with cold Arctic water. At its estuary, the St. Lawrence doubles in width to more than
kilometres before emptying in the Gulf of St. Lawrence An estuary is the wide part of a
river where it nears the sea; fresh and salt water mix.

River life In an awesome avian spectacle: every spring and fall, more than greater snow geese stage in the tidal marsh of the Cap Tourmente National Wildlife Area, on the north shore of the
St. Lawrence River. The geese build up their for the 3,000-kilometre trip to their prime breeding grounds on and Bylot islands or for the 900-kilometre journey back to their wintering grounds along the Eastern Seaboard of the United States. Once they’re done feeding on the roots of during the fall migration, the tidal marsh at Cap
Tourmente is stripped bare. Jacques Cartier, and Jesuit priests all wrote about the great flocks at Cap Tourmente in accounts of their travels. At the beginning of the
century, the greater snow geese were near extinction. Today, their numbers stand at more than , due in part to the establishment of wildlife and restrictions on hunting.
Cultural legacy The St. Lawrence is at the heart of most major developments in early Canadian history. When
first explored the river in 1535, were already settled in communities at Stadacona (Québec City) and (Montréal). It was known as
until the early 1600s. As the main route into the interior of the continent, the
St. Lawrence was used by French explorers and traders to establish a colonial . By the mid-18th century, most of the land along the river between Montréal and Québec was divided into the long, narrow farms of the system. The mighty river served as a route for commerce, starting with the and later with . With the completion of the St. Lawrence Seaway — a system of locks, canals and channels linking the Great
Lakes and the St. Lawrence River with the Atlantic Ocean — in , the river became one of the most important transportation and industrial corridors in the world.

Current state For centuries, the St. Lawrence River has been intensively developed. By the second half of the 20th century, its banks were largely between Montréal and Québec and its waters heavily . In 1970, the Canadian government conducted its first water-quality study of the St. Lawrence. efforts to protect the waterway have only been introduced in the last years. Some of the main sources of pollution include municipal and industrial .
A recent report by the St. Lawrence Action Plan, a Canada-Quebec initiative, indicates that the river is now than it was during the second half of the 20th century. The level of
contamination has decreased and some animal populations, such as the northern , which was on the verge of disappearing in the 1960s, have recovered. In some areas, the water is safe enough for and freshwater fish are generally fit to eat. But contaminants trapped in still present a threat to the St. Lawrence. The population is still endangered, though its population has stabilized in recent years. And the river’s continues to be affected by habitat loss and other human disturbances, as well as the invasion of foreign species.
