Air pollution in Mexico

When I was riding the both articles I identified that of course the scientific article has so much more information than the article that I just found on a website. Also I realize that the scientific article for me it is so much difficult to understand because most of them writer use so many different terms or words that are difficult to understand. Both articles are a little bit different because one of them is about the effects of air pollution in Mexico and it is the scientific article. The other article for me is more understandable because is more directly about air pollution but both of them have relation because is similar topic but in different way.

 Soil erosion in Mexico

On these two articles we can see that the information is a little bit different because one is more related with the soil erosion in some parts of Mexico such as the 80% of the land is subject to erosion. The central state of Michoacán has one of the highest levels of soil erosion, with more than 2 million hectares affected, 70% of the surface area. The second article explain more about soil erosion caused by prehispanic agriculture this scientific article has more information about the why and how the prehispanic agricultures helps to accelerated the soil erosion. Something interesting I saw was that both articles are so different because maybe is a different topic I was trying to find similar articles but I couldn’t.  (Universidad Nacional Autónoma de México, Universidad Michoacana San Nicolas de Hidalgo, Colegio de Postgraduados en Agrociencias).  (UE 2002-2006)  cited 1/27/2014.

The article I like 

The article I think is more important for me is the one that is about the (air pollution in Mexico). For me it is a very important article because the air in Mexico is has been polluted principality for the smock of the many cars that most of them have not catalytic converter and the CO2 that cars make is so bad for our environment. Also is because there are so many people living in the city so consumption and the burning of fossil fuels are enormous. Some of the chemicals that affect and are bad for the air such as: Sulphur Dioxide, Nitrogen Dioxide, Carbon Monoxide, those are some of the main contaminants that cause air pollution in Mexico City.
