"Half of the global population already lives in cities, and by 2050 two-thirds of the world's people are expected to live in urban areas" (Leen)says the National Geographic. When one thinks about how crowded our cities are now, its hard to imagone how bad itll be in 2015.

In the radio interview analysis on BBC News diffused on November 20th, 2008 Mukul Devichand looked at urban development of London, Delhi and Mumbai. He contrasted cities across the planet to understand why cities are repeating the same odd choices and architectural model. He came to the conclusion that “cities are competing for economic supremacy and globalised services” (Devichand, 2008 para 3).

The article, “Collective rights ‘offer hope for global fisheries’” by Mark Kinver released in 2013 on BBC News reflects the problem of overfishing and the possible solutions to this global issue. Ragnar Arnason from Iceland University emphasized on the fact that the previous trials failed to protect the fishery industry (Kinver, 2013, para 1). Indeed, he said that there is major problem of global over-exploitation of fish. According to him, the problem started due to the improvement of technology available for fishers and the rise in human population.

The article Greenhouse Gases Hit Record High Amid Fears of CO2 Saturation Point, published by Brian Clark Howard, has as a goal to inform people about the issues brought up by greenhouse gases, which cause global warming. Howard emphasizes on the fact that, even there is no actual scentific concensus on the matter, a saturation point of CO2 gases which can be absorbed in oceans, plants, etc. may soon be reached. Moreover, the emissions of carbon dioxide have increased considerably since the 1980's.

In the article, “Study finds snowpack in California’s Sierra Nevada to be lowest in 500 years” by Nicholas St. Fleur released last September in The New York Times describes how the global warming affects California. This region of the United States has a “Mediterraneanlike” climate. In other words, most precipitations occur during the winter and summers are dry (St. Fleur, 2015, para.10). Therefore, the snowpack is used to fill a third of potable water for California’s reservoir. This water supply can also be used to fight wildfires and produce electricity (St. Fleur, 2015, para.5).

In the article, ‘UN ‘concerned’ by world population growth trends,’ by Camille Ebden released in 2011 on BBC News reflects upon the population growth issue that the Earth is undergoing. Indeed the population of our planet increased dramatically in the last centuries. Our global population could even reach a population of 14 billion by 2100 if humans stay passive about the situation. This situation mostly affects developing countries since they have the higher rates of population growth and they are more affected by famine (Ebden, 2011, para.4-5).
