Right to Life – Right to breathe clean air
By Dr. Ranil Senanayake
‘When you cannot take a breath, nothing else matters’ – American Lung Association
The most important thing in our lives that we forget is the air that we breathe. The air or atmosphere is part of the great global commons that every living being depends on. What is it?
Air is 78 percent nitrogen, 21 percent oxygen, 0.93 percent argon and 0.04 percent carbon dioxide. Although oxygen is the third most abundant element in the universe, free molecular oxygen (O2) is one of the rarest things in the entire universe. The only place known to have an atmosphere with O2 is planet Earth.
An exercise: Close your eyes, take a deep breath and know that your breath was made possible by a plant, somewhere at some point in time on this planet. Take a minute to be thankful for your easy breath. On average, a human needs about 750 kg of oxygen per year. All of humanity consumes about 7 billion tonnes per year.
The free oxygen in the atmosphere is 1.2×1015 tonnes (12,000,000,000,000,000 t), but it is unstable in our planet’s atmosphere and must be constantly replenished by photosynthesis in green plants. Without plants, our atmosphere would contain almost no O2. An important thing that needs international address is the fact that the system that replenishes the oxygen of our atmosphere is under threat. We remove the vegetation that produces oxygen at a prodigious rate. According to Global Forest Watch, we fell about 15 billion trees each year. With one tree producing about 120 kg of oxygen per year, the loss of oxygen production is massive. The impact on the oceans is becoming just as serious.
Oxygen is not only consumed by transport and steel production, it is also used to improve the thermal efficiency of fuel. Oxygen is used to treat polluted water and hazardous wastes and for the gasification process of coal. The gas can also replace chlorine in the pulp and paper industry in order to reduce pollution. Oxygen also finds large applications in the medical industry. The unaccounted uses from rocketry and the military have begun to eat into the replenishment rate of oxygen into the global commons at a prodigious rate.
Currently, at 20 percent, any drop in the local oxygen concentration can be disastrous, below 19.5 percent it can have adverse physiological effects and in atmospheres with less than 18 percent oxygen, it is life-threatening. While the concentration in the global commons is still acceptable, many large cities today are recording a drop in the local oxygen concentration with a rise in urban pollution.
As human activities have caused an irreversible decline of atmospheric O2 and there is no sign of abatement, it is time to take action to promote O2 production and pay for industrial use and consumption of O2. Vehicular traffic in cities with poor airflow design transforms molecular oxygen O2 into Ozone (O3). Ozone is good when it is high up in our atmosphere. It protects us from sunburn. Ozone is bad when it is close to the ground where we can breathe it in. You can’t see Ozone in the air but bad Ozone levels are sometimes called smog. It forms when chemicals coming out of cars and factories are cooked by the hot sun.
Breathing in Ozone can make you cough. It can also make it harder for you to breathe. Ozone might even make it hurt to take a breath of air. When you breathe in Ozone, it makes the lining of your airways red and swollen, like your skin would get with sunburn.
Unfortunately, adding to the problems of mining the global commons of air for its oxygen, there is also the issue of unchecked pollution. Air pollution has become a very serious and very visible burden on humanity. The WHO estimated that it was responsible for three million premature deaths worldwide per year in 2012; much of this mortality is due to exposure to small particulate matter of 2.5 to 10 microns in diameter (PM10) which causes cardiovascular and respiratory disease, and cancers.
Air pollution adversely impacts even healthy people; the effects include respiratory irritation or breathing difficulties during exercise or outdoor activities. The current health status and the pollutant type and concentration, or and the length of exposure to polluted air, determines the rate of cardiovascular and respiratory disease, and cancers. High air pollution levels can cause immediate health problems.
The air in Colombo is already of poor quality. PM10 has an annual average of 36 µg/m3 (micrograms per cubic meter). That’s 3.6 times the safe level set by the WHO. While the well-being of the citizens of Colombo seems the least important to the planners of our future, we need to inform ourselves on the cost we have to pay, so that we could defend ourselves from the consequences of ill-informed decision making.
The current air pollution level in all of Sri Lanka has an annual average of 22 µg/m3 of PM2.5 particles which is 2.2 times the WHO safe level. It has also been estimated that 7,792 people died from air pollution-related diseases and that the rate is increasing each year. The top illness caused by air pollution is Ischemic heart disease. Further, 33 children die of air pollution-related diseases every year. Currently, the main source of ambient air pollution in Sri Lanka is vehicular emissions, which in Colombo contributes to over 60 percent of total emissions. But, lurking in the activities of the proposed Port City and Megapolis, there is a huge hidden danger. The danger that uncontrolled construction debris will pose to air quality and to the health of the residents of Colombo city as well as creating a barrier to oceanic breeze that keep the air in Colombo reasonably clean.
As the skyline around Colombo will be increasingly blocked by current unplanned construction, the through-flow of air will be reduced. We can already feel the effect when we breathe at midday in Colombo.
Construction activities that contribute massively to air pollution, include landfilling, operation of diesel engines, demolition, burning and working with toxic materials. All construction sites generate high levels of dust (typically from concrete, cement, wood, stone and silica) which can carry for large distances over a long period. Construction dust is classified as PM10 or particulate matter less than 10 microns in diameter, invisible to the naked eye.
Another emerging threat to the air quality of this nation is the possibility that the Hambantota area could be used to house oil and chemical industries. The history of such industries has been one of polluting, as much as any government will let them. The air quality of this nation must be seriously addressed in the legislature and strong controls placed on activities that affect the quality of air.
It has been noted that the combined effects of ambient (outdoor) and household air pollution cause about seven million premature deaths every year, largely as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections. The pollutant load in the atmosphere needs to be strongly controlled as it interferes with our right to breathe.
Up till now there has been no serious attain paid to the quality of the air that we breathe. This raises a question: ‘If I and my ancestors enjoyed a certain quality of breath, is not the reduction of that quality an infringement of my established right?’

Panadura debate: special exhibition most welcome
The special exhibition displaying original manuscripts relating to the Panadura Debate at Rankoth Vihara is welcome and, as Nishantha Peiris mentions (News, 30 Aug), the debate gained international interest following the publication of a book containing the speeches made in the debate. The credit for this must be given to John Capper, the then editor of the Ceylon Times. He published an account of each day’s proceedings in his paper and the full text of the speeches in a book entitled ‘Full Account of the Buddhist Controversy Held at Pantura in August 1873.
The preface of the book stated: ‘In the belief that an authentic account of the Controversy which took place at Pantura in August last, between a Buddhist Priest and two Ministers of the Protestant religion, will be read with interest by a large number of persons here and in Europe. I have produced the proceedings in the present form. The report has been revised by the respective disputants, so that it may be taken as a correct account of what passed’.
Capper’s book was picked up by J M Peebles who was in India, who then published an extended version in the United States. If an original copy of Capper’s book is available in Sri Lanka, it should be exhibited in the Rankoth exhibition.
Yours faithfully,

In Memory of Dr Upatissa Pethiyagoda
It is with a deep sense of sadness that I record the passing of Dr Upatissa Pethiyagoda, who died on 27 August 2026 at the age of 94. To many, he was a distinguished scientist, accomplished administrator, diplomat and public intellectual. To me, he was much more than that.
Dr Pethiyagoda was a proud product of Trinity College, Kandy. At a time when a first class in Botany was a rarity, he obtained one and subsequently pursued postgraduate studies in London. His scientific career reflected not only his knowledge but, more importantly, an enquiring and restless mind that was never satisfied with simply accepting what was known.
In the 1970s, he headed the Plant Physiology Department of the Tea Research Institute of Sri Lanka. He was part of a formidable team of scientists that included Drs R L de Silva, R L Wickramasinghe, P Sivapalan, Tilak Wettasinghe and W Danthanarayana. They were scientists who contributed enormously to the development of the tea industry in Sri Lanka, and Dr Pethiyagoda stood comfortably among them.
In 1978, he moved to the Coconut Research Institute as its Director. It was there that I had the privilege of working with him. Those years left a lasting impression on me.
Dr Pethiyagoda was, in every sense, a complete scientist. Although his formal specialisation was plant physiology, he was remarkably comfortable discussing almost anything scientific. What distinguished him was his curiosity. He questioned the science behind the ordinary things that most of us simply accepted. I remember his asking questions such as, why is an orange green in Sri Lanka? It was typical of him: an apparently simple observation would lead him to ask what lay behind it.
That curiosity never left him.
After his tenure at the CRI, he undertook an FAO assignment in the Middle East, working on the improvement of date palms. There he was exposed to agriculture under conditions of severe water scarcity. He pursued this further during a visit to Israel, learning about agronomic practices suited to such environments. Later, when he worked with the Mahaweli Authority, he was able to translate that knowledge into practice, introducing high-value horticultural crops to Systems B and C.
What impressed me was not merely that he acquired knowledge, but that he connected knowledge from one context to another and turned it into practical solutions. His enquiring mind and analytical ability enabled him to do this with remarkable effectiveness.
He was equally impressive as a communicator. Dr Pethiyagoda was an eloquent speaker, whether he was talking about science, agriculture, public policy or the everyday affairs of our country. His speeches were often laced with wit, humour and the occasional tongue-in-cheek remark. But beneath the humour was a very serious mind. He was forthright in his opinions and, importantly, he was not afraid to express them, whatever the possible repercussions.
His contributions to the media demonstrated this courage.
Writing about the travel to London by a former President, he observed:
“Where a person enjoys immunity by virtue of his position, this carries a reciprocal obligation to exercise an abundance of exemplary behaviour. In effect, immunity is best exercised, when the need to invoke it, is never allowed to arise.”
[Immunity Does Not Confer Impunity – Colombo Telegraph]
That was quintessential Pethiyagoda—precise, pointed and impossible to misunderstand.
He was equally outspoken about the government’s decision to ban inorganic fertiliser with ‘immediate effect’. He was deeply distressed by what he believed would be the consequences for farmers, particularly the poorer farming community. He would speak about it almost every day, driven not by political considerations but by his conviction that science and evidence had been disregarded.
In one of his writings on the subject, he remarked:
“What the ‘Vipathmaga’ caper taught us was that advice of sundry ‘Experts’ can be disastrous. Professors of Surgery, clergymen and Pediatricians are not the best equipped to advise on fertilisers, as much as a Soil Scientist should not prescribe treatment for a sick child.’ [Some Lessons That Can Be Learned Even From Disasters – Colombo Telegraph]
And in another article, his frustration was summed up in the memorable words:
“Stupidity, like History, has a way of repeating itself.”
[Unscrambling eggs – Colombo Telegraph]
These were not simply provocative statements. They reflected a scientist who believed deeply that public decisions, particularly those affecting agriculture and the livelihoods of farmers, should be based on evidence and sound scientific advice.
Perhaps, what I will remember most about Dr Pethiyagoda is that his curiosity survived almost to the very end of his life.
Very recently, he was still asking questions and pursuing ideas. He was interested in the possible genetic differences between the waraka and wela varieties of jak, because he wondered whether the wela variety might have commercial potential for cellulose extraction. He was disappointed that he could not find relevant scientific literature in Sri Lanka. More than the particular subject, what struck me was that at 94 he was still thinking about a scientific question, looking for evidence and wondering whether an apparently ordinary resource could have an important national application. He lamented the lack of interest among scientists and academics in such questions of national importance. That concern, too, was very much part of who he was.
Dr Pethiyagoda also served as President of the National Academy of Sciences, Sri Lanka. Unfortunately, he was unable to complete his term because he was appointed Ambassador to Italy, with representation at the Food and Agriculture Organization in Rome. Even in that role, he remained very much the scientist. I understand that he made a significant contribution to FAO discussions. As Ambassador, he also had the unenviable task of entertaining Sri Lankan Ministers of Agriculture who attended FAO sessions. I know from my own conversations with him that those informal dinners were not merely social occasions. He would discuss agricultural issues with the Ministers, and I have little doubt that his views—and the force with which he expressed them—sometimes influenced their thinking.
Looking back, what I admired most about Dr Pethiyagoda was not any particular position he held or any particular achievement. It was the way he thought.
He questioned.
He analysed.
He connected ideas.
He challenged conventional wisdom.
And he was willing to say what he believed to be true.
He also demonstrated that science should not remain confined to laboratories, research papers or academic institutions. For him, science was a way of looking at the world and, ultimately, a means of improving the lives of people.
It is perhaps ironic that, only a few months ago, he wrote about “The Cost of Dying”, as distinct from the “Cost of Living”. In that article, he reflected on the manner in which our mortal remains should be disposed of, observing: “I am in two minds regarding the manner in which the mortal remains are disposed of, ‘according to the will of the deceased’. But with the cessation of the breath, ownership or tenancy ceases.” Even in contemplating death, he brought his characteristic questioning mind to the subject. What particularly caught my attention, however, was his explanation of the Buddhist practice of holding dânes (almsgivings) for monks of the local temple in the seventh day and third month following a death. I had never really thought about the significance of this practice before. That, too, was typical of Dr Pethiyagoda: he could take something that we had accepted as ordinary and familiar and make us stop, think and see it differently.
His passing has created a colossal vacuum in Sri Lanka’s scientific community. People of his intellectual breadth, curiosity, courage and independence are rare. We may not always have agreed with everything he said, but we could never doubt that he had thought deeply about it and that he had the courage of his convictions.
For those of us who had the privilege of knowing him, there is sadness in his passing. But there is also gratitude—for having known such an extraordinary mind, for having learnt from him, and for having witnessed at close quarters his unwavering commitment to science and to the development of our country.
I shall remember Dr Pethiyagoda with great affection and immense respect.
Ranjith Mahindapala
Past President, National Academy of Sciences of Sri Lanka.

A neighbour’s view of India’s strategic strengths
What India chooses to do with the strategic freedom it has built over eight decades may be the defining question of its next phase
by Milinda Moragoda
In the emerging global economy, countries will increasingly seek multiple sources of energy, technology, capital, minerals and markets. India can contribute by helping create an open network rather than another exclusive bloc.
As India marks eight decades of Independence, its strategic position has changed almost beyond recognition. Yet the central question of strategic autonomy remains. What India chooses to do with the strategic freedom it has built over eight decades may be the defining question of its next phase.
India has spent the past decade expanding its strategic choices — deepening ties with the US, Europe and Japan while maintaining important ties with Russia and strengthening engagement with the Gulf, Africa and Southeast Asia. Australia and New Zealand are also becoming increasingly important partners in the wider Indo-Pacific. At the same time, India has sought a larger voice for the developing world in international institutions. Strategic autonomy has traditionally been understood in diplomatic terms: the ability to maintain freedom of action without being drawn into competing power blocs. In an increasingly interconnected world, however, that freedom will depend just as much on economic choices.
The objective should be strategic interdependence — building sufficiently diverse relationships that dependence on any one country or economic system does not become a vulnerability. India is unusually well placed to pursue this. Its geography connects the Gulf and wider West Asia, the manufacturing economies of Asia, Africa across the Indian Ocean and the Eurasian space extending through Russia. The opportunity, therefore, is to become a connector between economies increasingly fragmented by geopolitical competition.
India’s relationship with Japan is extending into advanced manufacturing, technology, energy, semiconductors and critical minerals. Its engagement with the US is deepening across technology, investment, advanced manufacturing, energy and strategic cooperation, while its engagement with Europe is becoming increasingly economic and technological. Its relationships with the Gulf are expanding beyond energy into investment and connectivity. Australia and New Zealand add an important southern dimension to its wider Indo-Pacific engagement, while Southeast Asia provides pathways into wider Asian production networks.
Russia remains an important part of this equation. India’s continuing engagement with Moscow, alongside its deepening relationships with Washington, Tokyo, Europe and the Gulf, demonstrates that strategic autonomy gives India the flexibility to maintain important relationships across geopolitical divides.
China inevitably occupies a special place in this landscape. India’s answer cannot be either excessive dependence or complete separation. It will require strengthening domestic capabilities, diversifying supply chains and building partnerships elsewhere, while retaining space for engagement where interests permit.
India possesses another asset that few countries can match: a large, globally active and influential diaspora. Yet the diaspora can also present challenges, as political currents within these communities do not always align with India’s interests and can occasionally create sensitivities in its relations with host countries. The greater opportunity lies in nurturing the economic, intellectual and cultural connections the diaspora can create, while respecting its diversity and independence. In the emerging global economy, countries will increasingly seek multiple sources of energy, technology, capital, minerals and markets. India can contribute by helping create an open network rather than another exclusive bloc.
Ports, shipping routes, energy corridors, digital infrastructure, supply chains and trade agreements increasingly shape strategic influence. India’s challenge is to bring these strands together without turning them into a closed sphere of influence.
India’s economic rise will be more sustainable if other countries see themselves as participants in its growth rather than simply as markets for it. The value for India lies in making these relationships complementary rather than choosing among them. India’s leadership of the Global South can now move beyond representation in international forums towards creating an international economic environment in which developing countries have greater choices. India’s own experience is relevant here. It has moved from a relatively closed economic model towards deeper global integration while retaining a strong emphasis on domestic capability. The lesson is that openness and strategic autonomy need not be contradictory.
As the G20 meets again in Miami in December, India can continue to argue that the Global South should not merely seek greater representation within existing institutions, but a greater stake in shaping the economic networks and institutions of the future. An economically integrated Indian Ocean could allow countries such as Sri Lanka, Bangladesh and the Maldives to participate more deeply in regional supply chains, logistics, energy, tourism, technology and services. Influence based on shared prosperity is more durable influence based on dependence. India’s strategic opportunity, therefore, lies in becoming one of the principal connectors of a changing world.
