THE BURJ DUBAI

Dubai is a city located in the Persian Gulf. It is famous for its hundreds tourists attractions, and its skyscrapers like the Burj Dubai, the tallest tower on the world. This building and other structures shape the plan of the governments to transform Dubai in an important touristic center. The reason to make this transformation is because the oil in this region is going to end.

The Burj Dubai was open in January 2010, is the tallest building on the word with 828 m (2,717ft). The inspiration to design this tower was a plant native from the desert, it is called the Hymenocallis. It’s a flower with six petals.

Aurora Borealis
Aurora Borealis is a natural light in the sky. This natural effect occurs during the night in the Polar Regions. Auroras result from emissions of photons in the Earth's upper atmosphere, above 80 km (50 miles). Also, it’s related with solar wind, and collisions between magnetic ions and earth’s atmosphere.

I think that a wonder could be created for both nature and humans, because both of them have the capacity to develop amazing things in our lifes.The nature can create spaces to relax our minds such as an attractive landscape. However, humans can build places that could turn our life different, creating nature spaces for people to enjoy and entertain. Sometimes these places come from natural forms like Burj Dubai, for example.If I will have to choose between one of these, I think that my decision will be the aurora borealis because I prefer natural creations. Nature design original things and people could not manipulate these amazing and wonderful shows. For this reason, I am sure that natural designs are the most spectacular inventions around the world.

POLLUTION AND ITS CONSEQUENCES.

The world is rapidly urbanizing with significant changes in our living standards, lifestyles, social behavior and health. These changes can affect the environment because the nature was in balance before the human activities. However, the develop the industries came to supply their needs as it is the case of Medellin, specifically in the south.

The man is a weapon of destruction for the environment because he cannot measure the damages that is causing to the world. For example, when a person creates an industry is not conscious of the waste that he is putting on nature, especially in the air. The pollution is one of the air pollutants that is affecting the environment and the people, who live in big industrial cities. When people think about air pollution, they usually think about smog, but what the people do not know, is that the pollution can also exist inside their homes. In the smog there are present many chemical substances that affect people health.

Urban air pollution kills around 1.2 million people each year around the world, mainly due to cardiovascular and respiratory diseases. A major proportion of urban air pollution is caused by motor vehicles, although industrial pollution, electricity generation and in least developed countries household fuel combustion are also major contributors  

In the last years, pollution has been increasing in Medellin because of contaminated wind comes from many industries located in the south, and all the contamination cannot go out the “valle de aburra” because there is a layer of hot wind that covers the Aburra valley, and on it there is a cold one that does not let the wind rise and go out. Also, the mountains like “el alto de san Miguel” do not let the air circulate out of the valley.

Cities around the world are making many decontamination projects because they are nothing that their lifes are directly related to the environment, and with technological, and industrial development they are not only destructing the world but also their lifes.

Finally, pollution can affect people health killing many people around the word, and these problems are caused by human activities altering the normal cycle of nature. Each person has to be aware about the damages that come with the development.
