Environmental impact of electricity generation electricity sector is unique among industrial sectors in its very large contribution to emissions associated with nearly all air issues. Electricity generation produces a large share of Canadian nitrogen oxides and sulphur dioxide emissions, which contribute to smog and acid rain and the formation of fine particulate matter. It is the largest uncontrolled industrial source of mercury emissions in Canada. Fossil fuel-fired electric power plants also emit carbon dioxide, which may contribute to climate change. In addition, the sector has significant impacts on water and habitat and species. In particular, hydro dams and transmission lines have significant effects on water
The Nitrogen Fix The Nitrogen Fix The Nitrogen Fix is a 1980 science fiction novel by Hal Clement, and illustrators David B. Mattingly, and Janet Aulisio. The plot revolves around a nomadic family in a future where all oxygen in the Earth's atmosphere has combined with nitrogen, so the atmosphere is mostly nitrogen with traces of water, nitrogen oxides and carbon dioxide, and the seas are very dilute nitric acid. The family is allied with an alien, an octopus-like being, who can survive in the new atmosphere. Humans must live in shelters with oxygen-generating plants, or use suitable breathing equipment.
