Beaver

The beaver (Castor canadensis) is a herbivorous mammal. It is Canada’s largest rodent and the second-largest rodent in the world (after the capybara). It is primarily nocturnal and lives a semi-aquatic life. The beaver is one of the only mammals, other than humans, that can manufacture its own environment. It is known for building dams, canals and lodges. Its colonies are created by one or more beaver-built dams, which provide still and deep water for protection against predators. An emblem of Canada older than the maple leaf, the beaver has had a greater impact on Canadian history and exploration than any other animal or plant species. (See also Fur Trade in Canada.)

Flea

Fleas are very small, wingless, laterally flattened insects of the order Siphonaptera. They’re best known for being external parasites on mammals and occasionally birds. Adult fleas live in the fur or feathers of their hosts, feeding on their blood to survive and reproduce. While fleas do feed off humans, more common host animals include rodents, dogs and cats. The “human” flea, Pulex irritans, actually attacks a broad range of mammal species, and the same is true of most flea species that bite humans. About 2,000 species and subspecies are known worldwide, with at least 127 found in Canada, most of them in British Columbia and Alberta.

Dinosaurs and Canada

Dinosaurs were a group of animals that dominated the land environments of every continent. They lived from the late Triassic period to the end of the Cretaceous period (225 to 65 million years ago). However, birds are the direct descendants of dinosaurs, meaning dinosaurs are still common today. Paleontologists have found more than 100 different species of dinosaurs in Canada. The primary site of these fossils is Dinosaur Provincial Park, Alberta. Well-known dinosaurs first named from Canadian specimens include Albertosaurus, Centrosaurus, Corythosaurus, Dromaeosaurus,Gorgosaurus, Lambeosaurus, Pachyrhinosaurus, Parasaurolophusand Styracosaurus.

Coal in Canada

Coal is a fossil fuel that has been used as a source of energy in Canada since the 18th century. Canada is home to 0.6 per cent of the world’s coal resources. Most of the country’s coal reserves (over 95 per cent) are found in AlbertaBritish Columbia and Saskatchewan. In recent years, the environmental movement has opposed the coal industry for disrupting local ecosystems, creating adverse health effects and for its large contribution to the carbon-dioxide emissions that drive climate change. In an effort to curb harmful emissions, the federal government has signalled its intention to phase out traditional coal-fired electricity by 2030, and Alberta has a plan to achieve the same goal as a province.
