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.

In the Article written by Fiona Woo, questions have risen about whether or not sustainable urban development remains the best procedure to follow in our daily lives. “Sustainable development is not enough anymore”, says Woo. As a population, we have already exceeded the limits. The capability for future generation to meet its own needs is a very meagre possibility. People living in urban areas increase every year. In fact, statistics of people migrating to cities demonstrate that the people currently living in urban areas in Africa will triple by 2050.

In the article “Study shows urbanisation's impact on biodiversity” Mark Kinver, discusses the positive effects urban cities have on biodiversity. Now you must be wondering how a city can be biodiverse, well a lot of cities actually preserve certain areas such as parks and gardens, etc. and keep them green a healthy allowing things such as birds and plants to continue to live and grow throughout the city. Now Urbanization has caused species to decline yes but at least they are trying to gain back some of the species that urbanization caused some of to leave.

In the news article " how the world could be running out of fish" it refers back to our older generations and discusses how we use to be hunters and gathers and that now fish are the only wild anmals that we hunt in large numbers. Many of the animals left on the planet are not hunted as much as they use to  because there simply isn't  a great number of certain species.  Certain marine animals like whlaes won't even be seen by future generations because of the potential risk certain species are of becoming extinct.

In the article “Signs From Earth: The Heat Is On” by Joel Achenbach and Heidi Schultz they discuss how to many peoples beliefs global warming is not important enough to worry about because the next generation will have to deal with it and that generation is our generation. Most think that warning of global warming are just a scare tactics to scare us out of our cars and on our feet. This subject is very important and not just a scare tactic.

This article written by John Warrick, presents two studies about how global warming could slow down or even shut down the ocean circulation in the Atlantic’s ocean, North America and Europe. Indeed, the purpose of this article is to demonstrate, through research made by teams of scientists, the perturbations of the global ocean current caused by climate change. It shows how the direction of the waters in the ocean changed and how rapidly the melting Artic ice is close to halt the ocean’s normal circulation. The first study, done by three scientists from the Alfred Wegener Institute in Germany, explains how the rapid melting of the ice in Greenland could reverse the circulation of the ocean in the Atlantic. In fact, this is an important system where cold dense saltwater is pushed into the deep ocean and warms Europe’s climate by helping transport water to the north. All this is shown through computers. Also, they used new methods to estimate in more details how much the melting of the ice could really affect ocean circulation. This melting ice becomes freshwater that goes into saltwater. Indeed, freshwater is less dense than saltwater. Thus, freshwater coming from ice disrupts the normal flow. The second research, done by some scientists from Texas, illuminates us by explaining how the Earth climate changed the ocean circulation 12,000 years ago. The climate that we have now is a consequence of what happened 12,000 years ago. Finally, the author states that there are temperature changes associated with a slowdown of the ocean circulation. Therefore, he suggests that we should immediately act and try to stop the change as long as it is possible. Ocean circulation plays a big role in the global climate because of the water they transport. Indeed, without ocean circulation the poles would be colder and the equator would be warmer. All this is to say that we need to be more careful and prevent stopping that circulation cycle for good. We should all try to live a better life that takes into consideration climate change. There are personal lifestyle changes that can be made that could help reduce our carbon impact for instance. For example, we can try to take more often public transport, which will result in less pollution. There is so much that each individual can do. At the end, as a population, we can make a huge change in our environment. http://www.washingtonpost.com/news/energy-environment/wp/2015/09/07/new-...

Journalist Barrie McKenna discusses the potential of one of Canada’s most abundant natural resources: water. Should Canada consider exporting water to other countries, such as the United States, for profit? McKenna says we should.
