Indigenous Peoples' Medicine in Canada

Since time immemorial Indigenous peoples in Canada have been using plants and other natural materials as medicine. Plant medicines are used more frequently than those derived from animals. In all, Indigenous peoples have identified over 400 different species of plants (as well as lichens, fungi and algae) with medicinal applications. Medicine traditions — the plants used, the ailments treated, protocols for harvesting and application, and modes of preparation — are similar for Indigenous peoples across the country. In many Indigenous communities, there are recognized specialists trained in traditional medicine, and their practice often reflects spiritual aspects of healing as well as physical outcomes. In many cases, the therapeutic properties of Indigenous medicines are attributable to particular compounds and their effects on the body, but in other instances, their application is little understood by western medical practitioners. Within Indigenous communities, specific methods of harvesting and preparation of medicines are considered intellectual property of particular individuals or families.

Natural Gas in Canada

Natural gas ranks among the fastest-growing energy sources in Canada and is seen by many in the energy industry as a game-changer, a comparatively clean, low-cost and versatile fuel. It can directly generate power and heat and can be chemically altered to produce a wide range of useful commodity chemicals. It burns cleaner and more efficiently than other fossil fuels, releasing significantly fewer harmful pollutants into the atmosphere. Natural gas is colorless, odourless, shapeless, lighter than air and contains a mixture of several hydrocarbon gases, which are organic compounds consisting of some combination of hydrogen and carbon molecules. The primary consumers of natural gas are the industrial (54.1 per cent), residential (26.6 per cent) and commercial sectors (19.3 per cent). Canada is the fifth largest natural gas producer after the United States, Russia, Iran and Qatar. Currently, all of Canada’s natural gas exports go to the United States through a network of pipelines, making Canada the largest foreign source of US natural gas imports. At the end of 2016, Canada had 76.7 trillion cubic feet of proven natural gas reserves and had produced 152 billion cubic metres of natural gas that year. It is forecasted that global natural gas consumption will double by 2035.

Navigation

Evidence suggests that the Phoenicians, Arabs and ancient Greeks were familiar with the use of nighttime positions of stars and constellations to aid in marine navigation, but this knowledge was lost to Europeans in the Dark Ages and only regained after about the year 1000 from the Arabs.
