Lakes and rivers cover 7 percent of the country. Catchments - assemblages used to capture and retain rainwater and runoff; an important water management technique in areas with limited freshwater resources, such as Gibraltar.
Overgrazing - the grazing of animals on plant material faster than it can naturally regrow leading to the permanent loss of plant cover, a common effect of too many animals grazing limited range land. Ultraviolet UV radiation - a portion of the electromagnetic energy emitted by the sun and naturally filtered in the upper atmosphere by the ozone layer; UV radiation can be harmful to living organisms and has been linked to increasing rates of skin cancer in humans.
The government has also passed regulations that mandate lower vehicle emissions and more efficient fuel usage. Potable water - water that is drinkable, safe to be consumed.
Soil erosion - the removal of soil by the action of water or wind, compounded by poor agricultural practices, deforestation, overgrazing, and desertification.
The conservation organization said Canada moves more water from one watershed to another than any other country in the world and this activity can be devastating to ecosystems.
Welcome to Canada Canada is largely defined by its size, as the second-largest country in the world, and sparse population, with about 75 percent of Canadians living within miles of the United States of America. The oil and gas industry is a huge source of income for Canada but it is also a massive contributor to greenhouse gas emissions Image credit: The country generates enormous wealth from its oil and gas operations.
Noxious substances - injurious, very harmful to living beings. It works on an international level to encourage other nations to help slow the effects of this problem. Endangered species - a species that is threatened with extinction either by direct hunting or habitat destruction.
Canada is only ranked 16th among the top 25 exporters, with China, Germany and the US taking the top three export spots. Environmental Issues of Canada With the Arctic warming faster than any other biome recently, Canadians are particularly concerned about the impacts of climate change.
Aerosol - a collection of airborne particles dispersed in a gas, smoke, or fog. To tackle greenhouse gas emissions in the electricity sector, the Canadian government has banned the creation of new coal-fired power plants. Biomass - the total weight or volume of living matter in a given area or volume.
Poaching - the illegal killing of animals or fish, a great concern with respect to endangered or threatened species.
Desertification - the spread of desert-like conditions in arid or semi-arid areas, due to overgrazing, loss of agriculturally productive soils, or climate change. Salination - the process through which fresh drinkable water becomes salt undrinkable water; hence, desalination is the reverse process; also involves the accumulation of salts in topsoil caused by evaporation of excessive irrigation water, a process that can eventually render soil incapable of supporting crops.
Afforestation - converting a bare or agricultural space by planting trees and plants; reforestation involves replanting trees on areas that have been cut or destroyed by fire. Acidification - the lowering of soil and water pH due to acid precipitation and deposition usually through precipitation; this process disrupts ecosystem nutrient flows and may kill freshwater fish and plants dependent on more neutral or alkaline conditions see acid rain.
In northernmost Canada only 12 per cent of the land is suitable for agriculture due to the harsh climate, resulting in most of the population of Canada living within a few hundred kilometres of the southern border. Metallurgical plants - industries which specialize in the science, technology, and processing of metals; these plants produce highly concentrated and toxic wastes which can contribute to pollution of ground water and air when not properly disposed.The Most Popular Environmental Issues of See where voters on polling on the most popular Environmental issues of News about climate change and other environmental issues and the people and organizations behind the science.
About "Environment & Nature" Inuit experts and Environment Canada scientists are working together to manage an explosion in snow goose populations. Inuit Circumpolar Conference (ICC) - represents the roughlyInuits of Alaska, Canada, Greenland, and Russia in international environmental issues; a General Assembly convenes every three years to determine the focus of the ICC; the most current concerns are long-range transport of pollutants, sustainable development, and climate.
Environment Canada has issued a special weather statement, saying a cool air mass will invade much of Alberta, “bringing with it weather. Canada: Environmental Issues, Policies and Clean Technology Coal mines, like this one pictured in Alberta, are important for Canada's energy needs.
