I think this is a very complex and delicate subject, I always hears about how the foreign people didn’t respect the rights of the native people, this is not only a problem in Chile, is the same in other countries like United States or Brazil.
First we need to understand this problem, the Mapuche Conflict (or Mapuche issue) is referred to the revival and reorganization of the Mapuche communities for autonomy and land reclamation since the return of democracy in Chile primarily through footage claimed and intimidating land owners and staff of these lands with armed or incendiary attacks. Their demands revolve around three areas: judicial independence (own right), the return of the lands, financial claims and cultural identity.
If we understand that these people don’t feel they belong to Chile, is hard to say is there is an easy resolution of this conflict. Moreover the politicians became this entire subject in a circus; for example was applied an antiterrorist law, they expropriate Mapuche’s lands and always make promise they don’t pretend to fulfill; this action made more strained the relation between the Mapuche and the Chileans.
It is hard to see how your own country is separated in different thoughts and with an impossibility to make an agreement about all the need from each faction. Who have to make the first approach, I think the government, but like I say, they transform this subject in a circus, they don’t pretend to take with seriousness the Mapuche conflict.
Also I don’t approve any of the ways used for the Mapuches, I think that sometimes they are really terrorist. There is no possible explanation that can justify they behavior, more people would die because they risky actions, besides no one will be benefit because they criminal and violent actions.
I Hope someone could mediated in this situation and have a peaceful resolution. Sometimes is difficult to understand the human’s actions

Post 8: My thesis
My thesis is the development of a simulation model of the oxygen transport in soil with 3 to 5 % of Organic Matter content, this wasn’t my original subject, but after a few discussions with my tutor we decided this topic as the most suited thesis to develop.
In O’Higgins, agriculture is one of the most important economics activities, and the fruit production is very sensitivity about environmental stress like unbalanced water content in soil, this unbalanced could causes water deficit in plant or stomatal closure because oxygen deficit to root respiration.
Oxygen is necessary to plant and microorganism respiration, without oxygen the soil is unable to maintain his basics functions. In the same way, begin anaerobics processes and the soil accumulates carbon dioxide, this gas inhibits the roots growth.
To improve the irrigation management is necessary to know the behavior of oxygen and water in soil, bad irrigation management generally cause oxygen deficit and the problems that I mention above.
Therefore the main reason to my thesis is to develop a tool to predict the oxygen concentration in soil, however there isn’t the same level of knowledge of this subject than in other countries, even when the soil that were used has less than 2% of organic matter content, making compulsory to our country have studies in this field of research.
I hope that my thesis became a useful tool to the agronomist, which allows to improving the irrigation management in fruits orchards independent of the soil type.
I forgot to mention that the soil type is highly related with the air capacity of a soil and also with the soil capacity to content water or oxygen, plus uncorrected agricultural management, the oxygen content will be diminish to dangerous level to plants growth.
This study could be just the beginning of other thesis that might find more suitable equations to oxygen diffusion or apply the same methodology to other conditions.

Post 7: Environment
First of all, I think that in this particular topic our society not so concern. Let this subject in different topics.
Pollution, could be one of the more important topics related with the human activities and environment, there is no anthropic actions without consequences thus all the activities we make generate environmental pollution. There is any way maintain our activities and generate zero pollution, in my opinion that is impossible, because we generate direct or indirect pollution and pollution could be chemical or physical, is not only related with waste or gas emissions, for example if we use the water of a river and the return the same amount of water to the river course, but with different temperature our activity generate pollution. Pollution is a very complex concept involves a lot of things related with the environment.
Climate change, in my opinion climate is always changing. The Earth is always in cooler o warmer cycles, we have son proves in the analysis that some researcher did in the Antarctic ice. Don’t you remember that in the 80’s we were talking about a new glaciations, because the temperatures were lower than the average of the 60’s or 70’s, but now we are talking that the Earth is getting warmer and this rise of temperature is related with the carbon dioxide. One of the most affrighting things of this assumption is that could be based in wrong information and in exponential model (the exponential model always rise). I think that we are not the problem…we need put all our effort in the previous topic.
Renewable energies, the renewable energies could the solution to the fossils fuels, one of the most important needs to a develop society is the energy, countries like USA or German consumes between 15 to 50 times the energy that we use in Chile, and they are changing from fossils fuels to renewable energies form the wind or the sun. This could the solution to some of our present problems, but we need to research more.
Carbon and Water footprint, the anthropics activities could be measure with these indexes, both are important and represent different thought the how to see the environment. In my opinion both could be used to make the difference in our actions, but nobody is teaching us the relevance of the environment in our life and how every step we make have a repercussions not only in our life but in the Earth.
