Environmental issues in Canada
There are many different types of environmental issues in Canada which include air and water pollution, climate change, mining and logging. Environmental issues based in Canada are discussed in further detail below. Climate change. Melting of the Arctic and its effects on marine ecosystems. Scientists across the world have already started to notice massive reductions in Canada's Arctic sea ice cover, particularly during the summertime. The shrinking of this ice results in the disruption of the ocean circulation, and changes in climate and weather around the world. The 2019 "Canada's Changing Climate Report", written  by scientists from institutions around the globe, states that the impacts of climate change on Atlantic Canada will be very diverse. One impact is that the sea ice will become thinner and will also form for much shorter periods of the year. And with less sea ice than the region usually gets now, wave seasons will become more intense. Atlantic Canada will see a relative rise in sea levels everywhere - a rise which is estimated to be 75 to 100 cm by the year 2100. Scientists also predict that even if emissions decrease, a 20-cm rise is expected to  take place during the course of the next 20 to 30 years. As the ocean warms and subtropical waters move north, the ocean will become warmer and saltier, and since warmer water holds less oxygen than cooler water, marine ecosystems can suffer and become less sustainable because of this lower oxygen level. In the journal, "Science", which was published in March 2019, it explains that warmer waters could actually increase fish stocks in certain regions, like the halibut found off the coast of Newfoundland and Greenland but other species such as the Atlantic Cod and albacore tuna might not be  able to cope with the conditions so well. Conservation. The Rainforest Action Network and indigenous groups have campaigned to protect the boreal forest of Canada from logging and mining. In July 2008 the Ontario government announced plans to protect some of the area from all industrial activity. Logging. Logging of old growth forest continues in Canada. The Ancient Forest Alliance is an environmental group in British Columbia, dedicated to stopping logging in endangered old growth forests, and ensuring the sustainable logging of second growth forests. The forests of Clayoquot Sound are still being logged. There are ongoing protests over the  logging and in 1993 it was the site of the largest act of peaceful civil disobedience in Canada. Pollution. Chemical pollution. The Aamjiwnaang First Nation community has expressed concern regarding its proximity to chemical plants, as birth rates of their people have been documented by the American journal "Environmental Health Perspectives" as deviating from the normal ratio of close to 50% boys, 50% girls. The ratio as found between 1999 and 2003 by the journal was roughly 33% boys, and 67% girls. The First Nation is concerned that this abnormal trend is due to adverse effects of maternal and fetal  exposure to the effluent and emissions of the nearby chemical plants. This is the first community in the world to have a birth rate of two girls to every boy. Mining pollution. Canada, like most other countries with significant
