In the article “Just How Far Will Urban Sprawl Spread?” by Dave Levitan, he explains the impacts of explosive growth in the cities we live in. According to Levitan, “in 1990, 40% of the global population lived in cities, in 2010, we reached the 50% threshold, and the percentage is projected to jump all the way to 70% by 2050. The rapid Increase in population in cities will mean more cities, bigger cities, and of course more sprawl according to Levitan.

Aly Thomson, Canadian Press contributor, in her article "Canada Overfishing: Cod Stock, Other Species May Never Bounce Back, Study Says", summarized a study that states that the cod population, along with other Canadian fish species, haven't been able to reproduce and grow their numbers or to even keep a steady population due to overfishing. Thomson also explained that fish species usually have a normal, periodic population growth and decline cycles but the cod population hasn't reached its norm level in over twenty years which is a very scary thing to think about.

              Elizabeth Palermo argues in her article "King Crabs Arrive in Antarctic, with Claws Out for Biodiversity" that king crabs could be invading the whole seafloor of Antarctica due to climate change. She states that these crustaceans do live all over the globe, especially in the Alaskan coast. However, it was only discovered recently by scientists that they had advanced to the cold seawaters of Antarctica. According to the studies, the king crabs could throw the ecosystem into disorder.

The article entitled "Species and ecosystem impacts" on the David Suzuki Foundation's website speaks mainly of the climate change going on in Canada and the effects that they will have on the ecosystems there. It also describes how this hanging climate is forcing animals and plants into migration. Sadly though, species aren't able to migrate at a fast enough pace to keep ahead of human induced climate change thus many species will go extinct because of human activities.

              The article "Cheap Oil an Opportunity for Fossil Fuel Price Reform" written by Glada Lahn argues that fuel costs should increase according to the severity it causes on health, carbon and resource degradation. She claims that the cut on fuel costs does not aid the environment's situation since it makes people buy more cheaper oil, hence, they produce more carbon dioxide (CO2) emissions from combustion.

The Skeena watershed on the northern coast of British Columbia is one of the most beautiful and important watersheds in Canada, as freshwater conservation specialist James Casey explains, it is a "rich ecosystem [that] also supports a rich economy that includes fisheries and tourism. The home to countless species, including the rare, pale-spirit bear found in that area, the Skeena watershed is an important natural site and should be treated and protected as such. Unfortunately, that is not the case. The Skeena watershed is not protected under any policy of conservation.
