Losing Oxygen
The ability of expressing our fundamental right to breathe clean air is over. The Global Commons of air is rapidly being impacted, in addition to an increase in the concentration of Carbon Dioxide and a decrease in Oxygen concentration. The concentration of toxic gasses and airborne particulate matter in the atmosphere is increasing. While a global compact on the quality of air as a fundamental right, is urgent consideration of its impact on health must also become a matter of concern. he most essential thing for our existence is the ability to breathe. The air that we take for granted is like an invisible river of gasses considered a part of the ‘Global Commons’ or those resources that extend beyond political boundaries. The Commons of air is composed of a mix of gasses, the dominant being Nitrogen at about 78%, followed by Oxygen at 21%. Carbon Dioxide that is contributing to climate change accounts for only 0.04% and demonstrates how small changes in the concentration of gasses in the atmosphere can bring about massive changes to those that live in it.
The Oxygen component of the air we breathe was made by those earliest plants, the Bryophytes, which colonized land from 470 Ma onwards. This land colonization increased atmospheric oxygen to present levels by 400 Ma. The fire-mediated feedbacks that followed have stabilised high oxygen levels ever since, shaping subsequent evolution of life. Oxygen is the most crucial element on earth for the aerobic organisms that depend on it to release energy from carbon-based macromolecules. The current stocks have been maintained over millions of years by plants, terrestrial and oceanic. To sustain a gaseous concentration at around 21% of the air we breathe. This level is required to maintain a healthy body and mind. A lowering of this concentration has consequences. At 19% physiologically adverse effects begin. Impaired thinking and attention, reduced coordination, decreased ability for strenuous work is experienced, at 15% Poor judgment, faulty coordination, abnormal fatigue upon exertion, emotional upset Levels below this lead not only to very poor judgement and coordination but also impaired respiration, lung and heart damage. The question often arises: ‘If the atmospheric Oxygen concentration is 21% how can it vary so widely in different areas ? The answer is that ‘when you add other gasses, smoke and aerosols into the atmosphere, the concentration of atmospheric gasses will decrease in concentration. In some cities like New Delhi or Mexico have Oxygen concentrations measured at about 18% or lower.
There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. Although the magnitude of this decrease appears small compared to the amount of oxygen in the atmosphere, it is difficult to predict how this process may evolve, due to the brevity of the collected records. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health.
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 the Oxygen at a prodigious rate. According to Global Forest Watch we fell about 15 billion trees each year. With one tree one tree producing about 120Kg of Oxygen per year, the loss of Oxygen production through deforestation is massive. The impact on the oceans is becoming just as serious.
As human activities have caused irreversible decline of atmospheric O2 and there is no sign of abatement, It is time to take actions to promote O2 production and pay for industrial use and consumption of O2. Vehicular traffic in cities with poor air flow 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 near the ground where we can breathe it in. You can’t see ozone in the air but bad ozone levels is sometimes called smog. It is formed when chemicals coming out of cars and factories are cooked by the hot sun. Breathing in ground-level 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 a sunburn.
All this becomes even more pressing with the discovery of the “human oxidation field” a beneficial chemical microenvironment formed around the body’s surface that helps protect it from volatile organic compounds (VOCs). This field is generated by the reaction of ozone with oils and fats on our skin, especially the unsaturated triterpene squalene, which constitutes about 10 percent of the skin lipids that protect our skin and keep it supple. The reaction releases a host of gas phase chemicals containing double bonds that react further in the air with ozone to generate substantial levels of OH radicals. As the Ozone levels as in cities rise, the individual ‘human oxidation field’ looses its ability to maintain skin health.
In looking at the question of why there was such a rapid loss in the quality of air, the first study to systematically analyse the global O2 budget and its changes over the past 100 years, found that anthropogenic fossil fuel combustion is the largest contributor to the current O2 deficit, which consumed 2.0 Gt/a in 1900 and has increased to 38.2 Gt/a by 2015.
The inability to defend our fundamental right to breath seems to stem from the ability of any industry to discount the consequences of burning fossil fuels as a ‘negative externality’. Climate Change is one consequence, but the impact that lowered Oxygen concentrations will have on emerging urban populations seem disturbing. There is only one way to arrest the fall in atmospheric Oxygen, increase the rate of photosynthesis. There must be a protection of the existing stocks of photosynthetic biomass and programs that encourage increasing the standing stock of Oxygen to be able to sustain our fundamental right to breathe clean air.

When crisis comes to classroom:
How Sri Lankan children face natural disasters and economic problems
Sri Lanka has always found ways to survive storms. But during the past ten years, the storms have come more often and with more force. Floods have swallowed villages, landslides have buried homes, droughts have dried wells, and cyclones have pushed families out of their coastal towns. Then came the economic crisis in 2022 and 2023, which felt like an invisible disaster happening quietly inside every home. In the middle of all this were our schoolchildren. Their names rarely appeared in newspapers. Many of their stories were never told. A new study brings these voices together and shows how overlapping crises have reshaped education across the island. It also reveals something important: not all children suffered the same way.
This article tells that story through the experiences of teachers, parents and children. It also explains why some regions, some ethnic communities and some families struggled much more than others.
A decade of disruption
Over the past decade, Sri Lanka’s school system has been hit again and again. Floods in Ratnapura, Kalutara and Galle have become almost yearly events. Landslides in Badulla and Nuwara Eliya have cut off whole communities. Cyclones in Batticaloa and Ampara have damaged classrooms and left children in fear. Long droughts in the North and East have forced families to live with empty wells.
Then the economic crisis arrived. It brought fuel shortages, food shortages, transport problems, high prices and a heavy sense of uncertainty. Teachers stood in long queues just to buy a few litres of petrol. Parents struggled to buy exercise books. School buses stopped running. Many children stayed home. A school principal from the hill country said he could not remember a single year without crisis. “One month we have floods. The next month we have landslides,” he said. “The children keep losing learning time.” These experiences echo earlier concerns raised by Angela Little (2003) and Harsha Aturupane (2014), who showed that rural, estate and conflict-affected areas have always faced extra barriers. The new study suggests that recent disasters have made those old inequalities even wider.
When geography decides a child’s future
Sri Lanka is small, but the risks children face depend heavily on where they live. In the flood-prone river areas, schools often close for long periods. Many become temporary shelters filled with families, mats, cooking pots and clothing. Teachers say it can take weeks to clean and reopen classrooms. In the estate sector, children live high in the hills. When a landslide blocks a single narrow road, school simply stops. A teacher in Badulla said she once walked six kilometres during landslide season just to reach her students. “Some days I held on to tree roots to climb,” she said with a tired smile.
In cyclone-prone districts like Batticaloa and Ampara, fear becomes part of childhood. When the wind changes, parents start to worry. School roofs fly off. Books get soaked. Homes crumble. Recovery takes time, and many families cannot afford repairs.
In the drought-hit North and East, children sometimes miss school because they must help their mothers collect water. Teachers say these children return dusty, tired and unable to focus. Lalith Perera (2015) showed how geospatial tools can identify the highest-risk schools. The new study supports his findings and shows that children in these areas lose far more learning days than children in urban schools.
Ethnicity adds another layer to the struggle
Sri Lanka’s ethnic geography shapes children’s lives in deep ways. Tamil families in the North and East still face the long shadow of war-related poverty and lack of resources, as described by Shanmugaratnam (2015) and Samarasinghe (2020). Many schools in these areas are old, understaffed and in poor condition. When a cyclone or drought hits, recovery becomes slow and difficult. A teacher in Mullaitivu said her classroom lost its roof during a storm. “The children sat under a tree for weeks,” she recalled. “They still came. They did not want to fall behind.”
Muslim communities along the Eastern coast face frequent displacement during cyclonic seasons. When fishing families lose their boats and nets, income disappears. Children often miss school because parents cannot afford uniforms or bus fares.
Estate Tamil communities, studied earlier by Little and Jayaweera, continue to face long-term marginalisation. Many children rely heavily on school meal programmes. When the economic crisis disrupted these meals, teachers saw hunger more clearly than ever. Some children fainted in class.
In all these communities, ethnicity and geography combine to create layers of disadvantage that are hard to escape.
The economic crisis: A silent blow to education
The economic crisis of 2022–2023 affected every Sri Lankan home, but its impact was especially hard on low-income families. Economists like Nisha Arunatilake (2022) and Ramani Gunatilaka (2022) have shown how inflation and job losses pushed households into deep stress. These pressures directly affected children’s education.
With no fuel, many teachers could not travel. They walked long distances or hitchhiked. In some schools, several classes were combined because only a few teachers could come. School supplies became expensive. Parents reused old books or bought cheap, low-quality paper. Uniforms were patched many times. Some children wore slippers because shoes were too costly. Food shortages made everything worse. With rising prices, families reduced meals. In the estate sector, teachers saw hunger growing. Attendance fell.
Gender roles also shifted. Girls in rural areas took on childcare and cooking while parents worked longer hours. Boys were pushed into temporary labour. A mother in Monaragala said her teenage son cut timber to support the family. “He comes home exhausted,” she said. “How can he study after that?” Earlier, Selvy Jayaweera (2014) warned that crises deepen gender inequalities. The new study shows that her warning has come true again.
Schools tried to cope, but not all were ready
During field visits, researchers met principals who showed remarkable leadership. Some created disaster committees, organised awareness programmes and kept strong communication with parents. These schools recovered fast. Communities helped clean classrooms. Teachers volunteered for extra lessons. But many schools struggled. Some had no emergency plans. Others had old buildings damaged from past disasters. Some principals lacked training in crisis response. A few schools did not even have complete first aid boxes.
The difference between prepared and unprepared schools became painfully clear. After a cyclone in Batticaloa, one school restarted within a week. A nearby school stayed closed for nearly a month because debris and broken furniture filled the classrooms. Resilience expert Rajib Shaw (2012) highlighted the importance of strong partnerships between schools and communities. This study confirms that his message still holds true.
Families found ways to cope, but children paid the price
Every Sri Lankan family has its own survival strategies. Some borrow money. Some rely on relatives abroad. Some work extra hours. Some move to other districts. But these strategies often disrupt children’s schooling. When a father leaves home for work in another district, children lose emotional support. When a mother works late at a tea estate, older daughters must care for younger siblings. When a family moves temporarily, children lose teachers, routines and friends. A father in Ratnapura said he felt torn. “I want my daughter to study,” he said. “But how can I think of school when the river rises every year and we lose everything?” Years ago, sociologist K. T. Silva (2010) wrote about how poverty and displacement interrupt education. The new study shows that these patterns continue today.
How crises make old inequalities worse
One strong message from the study is that disasters do not create inequality they deepen what already exists. Rural schools with fewer resources suffer greater damage. Estate children who already face hunger become even more vulnerable. Tamil and Muslim families in hazard-prone areas must deal with both environmental and historical burdens.
Climate disasters also come in cycles. One flood does not end the struggle. Children who lose one month of school every year slowly fall behind. Their confidence drops. Their chances of continuing to higher education shrink. Meanwhile, well-resourced urban schools recover quickly. They have strong buildings, better communication and supportive parents. Their losses are small and temporary. The gap between privileged and vulnerable children grows wider each year.
What Sri Lanka can do now
Sri Lanka stands at a turning point. Climate change will bring more storms and droughts. The economy is still fragile. Schools must be prepared.
Every school needs a clear emergency plan. Preparedness should be part of daily school life safer buildings, evacuation routes, first aid training, and strong communication networks. Vulnerable regions need extra support. Flood-prone river basins, cyclone-hit coasts, drought-affected northern districts and the estate sector require more funding and attention. School meals must be protected. For many children, this meal is the difference between hunger and hope.
Teachers need help with transport and crisis training. Families need social protection so children are not forced into labour or long absences. Most importantly, education policy must place fairness at the centre. As Aturupane (2014) explained, equality cannot be achieved by giving all schools the same amount. Some schools need more because their burdens are heavier.
Stories that should guide policy
The most powerful part of this research is not the statistics. It is the stories:
A boy in Ratnapura losing his schoolbag to the floods.A teacher in Badulla walking through mud for her students.A mother in Batticaloa cooking in a cyclone shelter.A girl in Mullaitivu studying under a tree after her classroom roof blew away.A Muslim family in Ampara sheltering in a mosque during every storm.A Tamil child in Kilinochchi missing school to fetch water during drought.
These are the voices policymakers must listen to.
A future that values every child
Sri Lanka’s future depends on the minds of its children. If classrooms become unstable places, the country’s future becomes uncertain. But there is hope. Many teachers showed deep dedication. Many parents worked tirelessly to keep their children in school. Many communities showed unity and strength. If the government builds on this resilience through better planning, fairer funding and stronger support for vulnerable regions children’s dreams can survive the storms ahead. What we choose today will decide whether the next generation inherits disaster or opportunity.

The policy of Sinhala Only and downgrading of English
In 1956 a Sri Lankan politician riding a great surge of populism, made a move that, at a stroke, disabled a functioning civil society operating in the English language medium in Sri Lanka. He had thrown the baby out with the bathwater.
It was done to huge, ecstatic public joy and applause at the time but in truth, this action had serious ramifications for the country, the effects have, no doubt, been endlessly mulled over ever since.
However, there is one effect/ aspect that cannot be easily dismissed – the use of legal English of an exact technical quality used for dispensing Jurisprudence (certainty and rational thought). These court certified decisions engendered confidence in law, investment and business not only here but most importantly, among the international business community.
Well qualified, rational men, Judges, thought rationally and impartially through all the aspects of a case in Law brought before them. They were expert in the use of this specialised English, with all its meanings and technicalities – but now, a type of concise English hardly understandable to the casual layman who may casually look through some court proceedings of yesteryear.
They made clear and precise rulings on matters of Sri Lankan Law. These were guiding principles for administrative practice. This body of case law knowledge has been built up over the years before Independence. This was in fact, something extremely valuable for business and everyday life. It brought confidence and trust – essential for conducting business.
English had been developed into a precise tool for analysing and understanding a problem, a matter, or a transaction. Words can have specific meanings, they were not, merely, the play- thing of those producing “fake news”. English words as used at that time, had meaning – they carried weight and meaning – the weight of the law!
Now many progressive countries around the world are embracing English for good economic and cultural reasons, but in complete contrast little Sri Lanka has gone into reverse!
A minority of the Sinhalese population, (the educated ones!) could immediately see at the time the problems that could arise by this move to down-grade English including its high-quality legal determinations. Unfortunately, seemingly, with the downgrading of English came a downgrading of the quality of inter- personal transactions.
A second failure was the failure to improve the “have nots” of the villagers by education. Knowledge and information can be considered a universal right. Leonard Woolf’s book “A village in the Jungle” makes use of this difference in education to prove a point. It makes infinitely good politics to reduce this education gap by education policies that rectify this important disadvantage normal people of Sri Lanka have.
But the yearning of educators to upgrade the education system as a whole, still remains a distant goal. Advanced English spoken language is encouraged individually but not at a state level. It has become an orphaned child. It is the elites that can read the standard classics such as Treasure Island or Sherlock Holmes and enjoy them.
But, perhaps now, with the country in the doldrums, more people will come to reflect on these failures of foresight and policy implementation. Isn’t the doldrums all the proof you need?

GOODBYE, DEAR SIR
It is with deep gratitude and profound sorrow that we remember Mr. K. L. F. Wijedasa, remarkable athletics coach whose influence reached far beyond the track. He passed away on November 4, exactly six months after his 93rd birthday, having led an exemplary and disciplined life that enabled him to enjoy such a long and meaningful innings. To those he trained, he was not only a masterful coach but a mentor, a friend, a steady father figure, and an enduring source of inspiration. His wisdom, kindness, and unwavering belief in every young athlete shaped countless lives, leaving a legacy that will continue to echo in the hearts of all who were fortunate enough to be guided by him.
I was privileged to be one of the many athletes who trained under his watchful eye from the time Mr. Wijedasa began his close association with Royal College in 1974. He was largely responsible for the golden era of athletics at Royal College from 1973 to 1980. In all but one of those years, Royal swept the board at all the leading Track & Field Championships — from the Senior and Junior Tarbat Shields to the Daily News Trophy Relay Carnival. Not only did the school dominate competitions, but it also produced star-class athletes such as sprinter Royce Koelmeyer; sprint and long & triple jump champions Godfrey Fernando and Ravi Waidyalankara; high jumper and pole vaulter Cletus Dep; Olympic 400m runner Chrisantha Ferdinando; sprinters Roshan Fernando and the Indraratne twins, Asela and Athula; and record-breaking high jumper Dr. Dharshana Wijegunasinghe, to name just a few.
Royal had won the Senior & Junior Tarbats as well as the Relay Carnival in 1973 by a whisker and was looking for a top-class coach to mould an exceptionally talented group of athletes for 1974 and beyond. This was when Mr. Wijedasa entered the scene, beginning a lifelong relationship with the athletes of Royal College from 1974 to 1987. He received excellent support from the then Principal, late Mr. L. D. H. Pieris; Vice Principal, late Mr. E. C. Gunesekera; and Masters-in-Charge Mr. Dharmasena, Mr. M. D. R. Senanayake, and Mr. V. A. B. Samarakone, with whom he maintained a strong and respectful rapport throughout his tenure.
An old boy of several schools — beginning at Kandegoda Sinhala Mixed School in his hometown, moving on to Dharmasoka Vidyalaya, Ambalangoda, Moratu Vidyalaya, and finally Ananda College — he excelled in both sports and studies. He later graduated in Geography, from the University of Peradeniya. During his undergraduate days, he distinguished himself as a sprinter, establishing a new National Record in the 100 metres in 1955. Beyond academics and sports, Mr. Wijedasa also demonstrated remarkable talent in drama.
Though proudly an Anandian, he became equally a Royalist through his deep association with Royal’s athletics from the 1970s. So strong was this bond that he eventually admitted his only son, Duminda, to Royal College. The hallmark of Mr. Wijedasa was his tireless dedication and immense patience as a mentor. Endurance and power training were among his strengths —disciplines that stood many of us in good stead long after we left school.
More than champions on the track, it is the individuals we became in later life that bear true testimony to his loving guidance. Such was his simplicity and warmth that we could visit him and his beloved wife, Ransiri, without appointment. Even long after our school days, we remained in close touch. Those living overseas never failed to visit him whenever they returned to Sri Lanka. These visits were filled with fond reminiscences of our sporting days, discussions on world affairs, and joyful moments of singing old Sinhala songs that he treasured.
It was only fitting, therefore, that on his last birthday on May 4 this year, the Old Royalists’ Athletic Club (ORAC) honoured him with a biography highlighting his immense contribution to athletics at Royal. I was deeply privileged to co-author this book together with Asoka Rodrigo, another old boy of the school.
Royal, however, was not the first school he coached. After joining the tutorial staff of his alma mater following graduation, he naturally coached Ananda College before moving on to Holy Family Convent, Bambalapitiya — where he first met the “love of his life,” Ransiri, a gifted and versatile sportswoman. She was not only a national champion in athletics but also a top netballer and basketball player in the 1960s. After his long and illustrious stint at Royal College, he went on to coach at schools such as Visakha Vidyalaya and Belvoir International.
The school arena was not his only forte. Mr. Wijedasa also produced several top national athletes, including D. K. Podimahattaya, Vijitha Wijesekera, Lionel Karunasena, Ransiri Serasinghe, Kosala Sahabandu, Gregory de Silva, Sunil Gunawardena, Prasad Perera, K. G. Badra, Surangani de Silva, Nandika de Silva, Chrisantha Ferdinando, Tamara Padmini, and Anula Costa. Apart from coaching, he was an efficient administrator as Director of Physical Education at the University of Colombo and held several senior positions in national sporting bodies. He served as President of the Amateur Athletic Association of Sri Lanka in 1994 and was also a founder and later President of the Ceylonese Track & Field Club. He served with distinction as a national selector, starter, judge, and highly qualified timekeeper.
The crowning joy of his life was seeing his legacy continue through his children and grandchildren. His son, Duminda, was a prominent athlete at Royal and later a National Squash player in the 1990s. In his later years, Mr. Wijedasa took great pride in seeing his granddaughter, Tejani, become a reputed throwing champion at Bishop’s College, where she currently serves as Games Captain. Her younger brother, too, is a promising athlete.
He is survived by his beloved wife, Ransiri, with whom he shared 57 years of a happy and devoted marriage, and by their two children, Duminda and Puranya. Duminda, married to Debbie, resides in Brisbane, Australia, with their two daughters, Deandra and Tennille. Puranya, married to Ruvindu, is blessed with three children — Madhuke, Tejani, and Dharishta.
Though he has left this world, the values he instilled, the lives he shaped, and the spirit he ignited on countless tracks and fields will live on forever — etched in the hearts of generations who were privileged to call him Sir (Coach).
