Poooossstgraduate studies

As I was telling last blog post, I would like to continue studying after finish my career. There is so many cool things to study: Climate, Ecology, Genetics, etc. Nevertheless, I will focus my mind and energies on the subject I consider to be the most important for us right now. Hence, maybe I will study a Master in Climate Change or Urban Ecology, those are the areas I think will be important to understand on the future, considering the needs of the millions of people that live together right now, and the unsustainable conditions that underlies all this. In the future, I will consider to make a doctorate, but that is "flour from another sack" paraphrasing an expression that we have here on Chile.
I would like to study abroad, know other lands, other countries and cultures, and hence other realities that seem distant from me, but are as important to understand as mine, and thereby have a more complex formation on my area. The exactly country I don´t know, and I don´t really mind. It should be where the university that I need is. And the study system I don´t really mind either, it just has to give me the sufficient time to know the place.
I think is relevant to say that, even if I study abroad or not, I will come back to my country to give something back, considering that I have make all my studies in the educational public system. Maybe it isn´t the best there is, but it has give me the conditions and tools to be who I am now.
