Environment and Society: A challenge to teach

Teaching the undergraduate environmental science 1 course at UP is extremely challenging since I had to consign the syllabus to the trash bin! Why? It is because the traditional idea of chopping down the environmental system into its spheres e.g. lithosphere, atmosphere, biosphere, cryosphere, hydrosphere etc with their problems may not reflect what is happening in nature. Of course we have to introduce these "sphere" concepts because it allows us to have a good initial grasp of the various physical and biological processes happening. However in nature, what happens in the hydrosphere for example has a direct effect on the atmosphere and of course on the biosphere. All these processes are linked.

That everything is linked in nature is the central tenet of environmental science and environmentalism. The natural processes are linked and so too is the damage we humans inflict on these processes. Perhaps the history of our dealings with the environment can be simply summarized on how we use resources. Here is where I take off and teach about the story of humans and their relationship with the environment.

So we start with human evolution, the beginnings of agriculture, human population growth, biodiversity to globalization in the 21st century. It is a challenge to integrate this story since there are many disciplines to discuss. For instance with biosphere economics, we have to talk about capital both from the classical sense and the postmodern sense. Of course no one gets through the concept of capital without reading Karl Marx. So I have to brush up on my Marx! And so do the students.

Public health is no longer viewed just as a health care delivery issue but also as an environmental issue. Would you believe that the present brain drain of Filipino health workers is not just an economic issue but an environmental one? It is because the demographic transition in developed countries has resulted in a more resource intensive lifestyle and this requires skilled health professionals to fill the need.

These are the challenges we have to face. Environment is a complex system with a complex past and future.

President Manuel Luis Quezon's Code of Ethics

Being a denizen of Kyusi, in honour of the man who gave my city its name and for being the most colourful prez the Philippines ever had, I have the pleasure to post Manuel L Quezon's Code of Ethics on his birthday. Let us profit from the wisdom of the Kastila.

1. Have Faith in the Divine Providence that guides the destinies of men and nations.

2. Love your country for it is the home of your people, the seat of your affection and the source of your happiness and well-being. It's defense is your primary duty. Be ready to sacrifice and die for it if necessary.

3. Respect the Constitution which is the expression of your sovereign will. The government is your government. It has been established for your safety and welfare. Obey the laws and see that they are observed by all and that public officials comply with their duties.

4. Pay your taxes willingly and promptly. Citizenship implies not only rights but obligations.

5. Safeguard the purity of suffrage and abide by the decisions of the…

Simoun's lamp has been lit, finally.. not by one but by the many!

"So often have we been haunted by the spectre of subversion which, with some fostering, has come to be a positive and real being, whose very name steals our serenity and makes us commit the greatest blunders... If before the reality, instead of changing the fear of one is increased, and the confusion of the other is exacerbated, then they must be left in the hands of time..."
Dr Jose Rizal "To the Filipino People and their Government"
Jose Rizal dominates the Luneta, which is sacred to the Philippine nation as a place of martyrdom. And many perhaps all of those executed in the Luneta, with the exception of the three Filipino secular priests martyred in 1872, have read Rizal's El Filibusterismo. Dr Rizal's second novel is a darker and more sinister one that its prequel but has much significance across the century and more after it was published for it preaches the need for revolution with caveats,  which are when the time is right and who will instigate it.

Kartilla of the Katipunan

In celebration of Andres Bonifacio Day on Nov 30, I am blogging my English translation of the Katipunan's Code of Ethics or Kartilla (Kartilya). Recruits to the revolutionary association had to learn these by heart. The code was first written by Emilio Jacinto. The Kartilya remains as relevant today as in 1896 .

My apologies for errors in translation. I know there are better translations than this one.

1) A life not spent for a holy and noble cause is like a tree without shade or a noxious weed.

2) Acts that stem from pride and selfishness do not come from a desire to help others..

3) True holiness comes from helping others, charity towards others and the measure of such is in each reasonable act or word.

4) Dark or white your skin may be, all men are equal though one may be greater in knowledge, material wealth, beauty these do not add to one’s humanity.

5) Those who are men of goodwill put honour before concern for self and those who do no good puts the self before honour.

6) For an ho…
