Environment Of Canada
The environment is the subject of ministries at the federal and provincial level in Canada, with the current highest environmental government official being the national Minister of the Environment Steven Guilbeault. Canada's large landmass and coastline make it very susceptible to any climate changes, so any contemporary changes of climate in the country are of national concern. Of the factors caused by human intervention that can affect this environment, activities that sustain the economy of Canada such as oil and gas extraction, mining, forestry and fishing are influential. The increase in greenhouse gas emissions in Canada between 1990 and 2015 was mainly due to larger emissions from mining, oil, and gas extraction and transport. In 2011 United Nations said Canada's environment was the best in the world. Several governmental programs have been created to mitigate 20th and 21st century climate change, such as the One-Tonne Challenge. In late 2005 Canada hosted the United Na ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Carbon Tax
A carbon tax is a tax levied on the carbon emissions required to produce goods and services. Carbon taxes are intended to make visible the "hidden" social costs of carbon emissions, which are otherwise felt only in indirect ways like more severe weather events. In this way, they are designed to reduce carbon dioxide ( ) emissions by increasing prices of the fossil fuels that emit them when burned. This both decreases demand for goods and services that produce high emissions and incentivizes making them less carbon-intensive. In its simplest form, a carbon tax covers only CO2 emissions; however, it could also cover other greenhouse gases, such as methane or nitrous oxide, by taxing such emissions based on their CO2-equivalent global warming potential. When a hydrocarbon fuel such as coal, petroleum, or natural gas is burned, most or all of its carbon is converted to . Greenhouse gas emissions cause climate change, which damages the environment and human health. This negative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pesticides In Canada
The use of pesticides in Canada is regulated by the Pest Management Regulatory Agency, a division of Health Canada via the ''Pest Control Products Act'' . Pesticides are used predominantly by the agricultural sector. In 2016, 20% of reported pesticide sales were non-agricultural sector products (including forestry, aquaculture and assorted industrial uses), and just under 5% were domestic sector products. History The importation and sale of pesticide products has been regulated in Canada since 1927, originally under the federal ''Act to Regulate the Sale and Inspection of Agricultural Economic Poisons''. This Act was replaced in 1939 by the ''Pest Control Products Act'' (PCPA) and Regulations. Up until the 1940s, pesticides were primarily organic or inorganic substances (such as sodium chlorate and sulphuric acid) derived from natural sources. However these natural products had drawbacks such as their high rates of application, lack of selectivity and high phytotoxicity. In the ...

Climate Change In Canada
Climate is the long-term weather pattern in an area, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them. The climate of a location is affected by its latitude/longitude, terrain, altitude, land use and nearby water bodies and their currents. Climates can be classified according to the average and typical variables, most commonly temperature and precipitation. The most widely used classification scheme was the Köppen climate classification. The Thornthwaite system, in use since 1948, incorporates evapotranspiration along with temperature an ...
