Critical Thinking

  According with Jonathan Foley, feeding nine billion of people will be a big challenge for the humanity. The increment of the population by 2050 mean that we will increase the demand of meat, and in consequence we will need to double the crop production.  She thinks that we will need to balance between the demand of food, and the serious problems that the raise of the agriculture cause to the planet. Among the most dangerous complications of the agriculture that she mentions are pollution, emission of greenhouse gases, and reduction of the biodiversity. That’s why she proposes five steps that cut the environmental impact of the agriculture worldwide .    “The first step is to stop creating new farmland and instead use existing agricultural areas. This will prevent the destruction of rain forest and grasslands.”   The second step is to employ modern Tecnologies that permit reuse the existent lands. This will increase the yields on farms that are not productive.    The third step is to

How to Build Sitopia: Urban Gardens

     The worldwide population is currently around 7 billion, and is continuing to rise. It is projected that the population of the world will reach 9 billion by the year 2050. This massive increase in population will present a challenge regarding the question of how to feed so many people. Feeding a city is a complex process: it requires the harvesting of food, transporting, selling, purchasing, preparing, consuming and disposing of food waste. Carolyn Steel proposes that one answer to this upcoming challenge is that of the sitopia. A sitopia is an urban community built around its food system, that seeks to raise awareness among its inhabitants, encouraging them to eat healthy food and simultaneously create a balance between the needs of humans and the needs of the environment. According to Steel, "food belongs at the heart of society, not at its periphery. *" That is why we need to recognize the importance of the food in our lives, and build our cities around the places wher

Challenges for Foreign Students

(Bradbury, 1999).  Education is a right for all human beings, and it needs to be accessible for all people without discrimination. However, in some countries, education might be difficult for some students who encounter some challenges such as lack of resources or inadequate infrastructure. In the United States, there is a huge quantity of resources and technologies; even so, foreign students face three big challenges that they need to overcome: language barriers, class schedule, and financial issues.      The first challenge is language barriers that prevent students from communicating ideas and acquiring knowledge.

Advertising and Social Media

  Advertising has changed the process of communication after social networks appeared.  Before social networks, traditional advertisement used media such as newspaper, radio and television to communicate a commercial message. The goals of these messages are to influence the behavior of consumers. Communication in these types of advertisements is focused on visual or audio messages sent from one sender to several receivers. Additionally, communications in these types of media are unidirectional and they are directed to a sector of the population that is anonymous to the advertiser. However, new media like social networks have completely changed the communication process in advertising. Communication is no longer unidirectional, it is now bidirectional or multidirectional. An example of this is when a user shares content and it goes viral. Online social networks also eliminate geographical and temporal barriers by allowing advertisements to be seen anywhere and anytime. This helps the ad
