          In the article “Urban 'Heat Island' Effect is Only a Small Contributor to Global Warming, and White Roofs Don't Help to Solve the Problem, say Stanford Researchers” by Louis Bergeron, the author presents a new perspective to urban development. The purpose of this article is to establish a relation between urban heat islands and global warming. Based on new scientific researches done by Mark Jacobson, a professor of civil and environmental engineering who led the study, it was found that urban heat islands only had a minor impact on the overall global warming.

In the article Nowhere and Everywhere the Landscape of the Colorado Delta, it is said that, in comparison to 1922, the Colorado river is only 10% of its former size. In 1922, the river was composed of almost two million acres of wetlands. It is said that upstream users are depriving the river from its sources. The biodiversity of the river’s surrounding is dying fast. The explosive population growth of the area is believed to be at cause in this case.

             In the article “As seas rise, saltwater plants offer hope farms will survive”, the author Katy Daigle describes how the flooding of the coastlines in India has affected the agriculture. With climate change happening, more glaciers are melting and the sea levels are rising. This results in the flooding of many coastal farms in the south of Asia. For the 1.26 billion people living in India, relocation is not always an option, especially when food productivity needs to increase by 45% before 2050 if the population wants to be fed.

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.

A study made by an international team of scientific shows that for the half of the 28 extreme weather events last year (2014), climate change had something to do with it. This study as only been done recently because science was not up to the task before. The final goal of the study is to make society realise how climate change is affecting their day-to-day life and not only the life of other species. Scientists say that the raise of the sea ice level in Antarctic, that happened last year, is much less likely to happen in the following years.

In the article “ Resource depletion: Opportunity or looming catastrophe? ”, Richard Anderson, a news reporter at BBC, argues that an accelerated global population growth cannot be sustained with the present models of production in a world with finite resources. The current world population is around 6 billion and is predicted to increase up to 9 billion by 2050. Anderson based himself on McKinsey Global Institute to explain that the vast majority of the new population will be part of the middle class consumers, thus the demands in food and products will be very high.
