Late blight was responsible, in large part, for the Irish Potato Famine in the 1840âs, which resulted in the death and mass emigration of millions of people. Each year, Late blight reduces the yields of potatoes and tomatoes in the field and can cause major losses in potato tubers in storage. Late blight is found in most potato and vegetable growing regions of Canada and North America. Major outbreaks occur occasionally in Alberta (the last one was in 1993).
Disarmament is the act of reducing, limiting, or abolishing weapons. Disarmament generally refers to a country's military or specific type of weaponry. Disarmament is often taken to mean total elimination of weapons of mass destruction, such as nuclear arms.
Nuclear decommissioning is the dismantling of a nuclear power plant and decontamination of the site to a state no longer requiring protection from radiation for the general public. The main difference from the dismantling of other power plants is the presence of radioactive material that requires special precautions.
