James Bay Project
In 1971, Hydro-Québec and the government of Quebec initiated the James Bay Project, a monumental hydroelectric-power development on the east coast of James Bay. (See also Hydroelectricity in Canada.) Over the course of two phases, a total of eight generating stations were built, allowing for the pollution-free production of a significant portion of Quebec’s electricity. However, the project also profoundly disrupted the environment and the Indigenous communities living in the region, the effects of which are still being felt today.
A star is a large, self-luminous sphere of hot gas held together by its own gravitational force.
A pingo is an ice-cored hill typically conical in shape, growing and persisting only in PERMAFROST. The word "pingo" is of Inuit origin and was first used in the English-language literature by the botanist Alf E.
Harvestmen are Arachnids of the order Opiliones. Harvestmen is the preferred term but they are commonly called daddy-long-legs - even though many have short legs.
Artiodactyla is an order of even-toed mammals that walk on their toenails (unguis). This and the other order of hoofed mammals, the Perissodactyla, are collectively called ungulates.
The cuckoo (Cuculidae) is a family of birds with about 130 species, including common cuckoos, anis, couas, coucals and roadrunners, distributed almost worldwide.
Hummingbird is a common name for New World family Trochilidae, which numbers more than 300 species.

Bonnet Plume River
The Bonnet Plume River begins its journey in the Mackenzie Mountains on the Yukon and NWT border.
Associations between PLANT roots and FUNGI are mycorrhizae and are thought to occur on roots of 95% of all SEED PLANTS. They are probably essential to the survival in nature of both partners. The plant derives an enhanced ability to absorb essential minerals and greater resistance to root diseases.
Wind-scorpions are spiderlike and hairy. Their most striking feature is the enormous chelicerae, which are often about 25% of their body length.
A vertebrate is a member of the phylum Chordata.
Cranberries are tart, red berries. In Canada, most commercial production is in British Columbia and Québec.
Keystone XL Pipeline
Keystone XL was a proposed 1,947 km long pipeline project that would have carried crude oil from Alberta to Nebraska. It was owned by Calgary-based TC Energy Corporation. The pipeline was named XL for “export limited.” First proposed in July 2008, it was the prospective fourth phase of TC Energy’s existing Keystone Pipeline system. In Canada, Keystone XL had the support of both the federal and Alberta governments. However, the project faced significant opposition and legal challenges on environmental grounds. In January 2021, United States president Joe Biden cancelled its permit on his first day in office. On 9 June 2021, TC Energy and the Alberta government announced the termination of the Keystone XL pipeline.
The pear (genus Pyrus) is a common name for over 20 species of fruit-bearing and ornamental trees of the rose family.
Meteors, Meteorites and Impact Craters
The solar system contains many objects smaller than the planets (or their satellites) travelling in individual orbits about the SUN; space between the planets also contains myriad dust grains in the micron size range. Near Earth, dust concentrations are only a few hundred particles per cubic kilometre, but 35 000 to 100 000 t of extraterrestrial material enters the atmosphere annually, swept up by our planet from debris that is in its path or crosses its path.
In Canada the official national meteorological service definition of a blizzard is a period of 6 or more hours with winds above 40 km/h, with visibility reduced to below 1 km by blowing or drifting snow, and with windchills over 1600 W/ m2 (watts per square metre).
