Loss of free atmospheric Oxygen: We are taking out more than ecosystem can put back

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.

Tribute to a distinguished BOI leader

Published

on

Mr. Tuli Cooray, former Deputy Director General of the Board of Investment of Sri Lanka (BOI) and former Secretary General of the Joint Apparel Association Forum (JAAF), passed away three months ago, leaving a distinguished legacy of public service and dedication to national economic development.

An alumnus of the University of Colombo, Mr. Cooray graduated with a Special Degree in Economics. He began his career as a Planning Officer at the Ministry of Plan Implementation and later served as an Assistant Director in the Ministry of Finance (Planning Division).

He subsequently joined the Greater Colombo Economic Commission (GCEC), where he rose from Manager to Senior Manager and later Director. During this period, he also served at the Treasury as an Assistant Director. With the transformation of the GCEC into the BOI, he was appointed Executive Director of the Investment Department and later elevated to the position of Deputy Director General.

In recognition of his vast experience and expertise, he was appointed Director General of the Budget Implementation and Policy Coordination Division at the Ministry of Finance and Planning. Following his retirement from government service, he continued to contribute to the national economy through his work with JAAF.

Mr. Cooray was widely respected as a seasoned professional with exceptional expertise in attracting foreign direct investment (FDI) and facilitating investor relations. His commitment, leadership, and humane qualities earned him the admiration and affection of colleagues across institutions.

He was also one of the pioneers of the BOI Past Officers’ Association, and his passing is deeply felt by its members. His demise has created a void that is difficult to fill, particularly within the BOI, where his contributions remain invaluable.

Mr. Cooray will be remembered not only for his professional excellence but also for his integrity, humility, and the lasting impact he made on those who had the privilege of working with him.

When elephants fight, it is the grass that suffers

Published

As a small and open country, Singapore will always be vulnerable to what happens around us. As Lee Kuan Yew used to say: “when elephants fight, the grass suffers, but when elephants make love, the grass also suffers“. Therefore, we must be aware of what is happening around us, and prepare ourselves for changes and surprises.” – Prime Minister Lee Hsien Loong, during the debate on the President’s Address in Singapore Parliament on 16 May, 2018, commenting on the uncertain external environment during the first Trump Administration.

“When elephants fight, it is the grass that suffers”

is a well-known African proverb commonly used in geopolitics to describe smaller nations caught in the crossfire of conflicts between major powers. At the 1981 Commonwealth conference, when Tanzanian President Julius Nyerere quoted this Swahili proverb, the Prime Minister Lee Kuan Yew famously retorted, “When elephants make love, the grass suffers, too”. In other words, not only when big powers (such as the US, Russia, EU, China or India) clash, the surrounding “grass” (smaller nations) get “trampled” or suffer collateral damage but even when big powers collaborate or enter into friendly agreements, small nations can still be disadvantaged through unintended consequences of those deals. Since then, Singaporean leaders have often quoted this proverb to highlight the broader reality for smaller states, during great power rivalry and from their alliances. They did this to underline the need to prepare Singapore for challenges stemming from the uncertain external environment and to maintain high resilience against global crises.

Like Singapore, as a small and open country, Sri Lanka too is always vulnerable to what happens around us. Hence, we must be alert to what is happening around us, and be ready not only to face challenges but to explore opportunities.

When Elephants Fight

To begin with, President Trump’s “Operation Epic Fury”.

Did we prepare adequately for changes and surprises that could arise from the deteriorating situation in the Gulf region? For example, the impact the conflict has on the safety and welfare of Sri Lankans living in West Asia or on our petroleum and LNG imports. The situation in the Gulf remains fluid with potential for further escalation, with the possibility of a long-term conflict.

The region, which is the GCC, Iraq, Iran, Israel, Jordan, Syria and Azerbaijan (I believe exports to Azerbaijan are through Iran), accounts for slightly over $1 billion of our exports. The region is one of the most important markets for tea (US$546 million out of US$1,408 million in 2024. According to some estimates, this could even be higher). As we export mostly low-grown teas to these countries, the impact of the conflict on low-grown tea producers, who are mainly smallholders, would be extremely strong. Then there are other sectors like fruits and vegetables where the impact would be immediate, unless of course exporters manage to divert these perishable products to other markets. If the conflict continues for a few more weeks or months, managing these challenges will be a difficult task for the nation, not simply for the government. It is also necessary to remember the Russia – Ukraine war, now on to its fifth year, and its impact on Sri Lanka’s economy.

Mother of all bad timing

What is more unfortunate is that the Gulf conflict is occurring on top of an already intensifying global trade war. One observer called it the “mother of all bad timing”. The combination is deadly.

Early last year, when President Trump announced his intention to weaponise tariffs and use them as bargaining tools for his geopolitical goals, most observers anticipated that he would mainly use tariffs to limit imports from the countries with which the United States had large trade deficits: China, Mexico, Vietnam, the European Union, Japan and Canada. The main elephants, who export to the United States. But when reciprocal tariffs were declared on 2nd April, some of the highest reciprocal tariffs were on Saint Pierre and Miquelon (50%), a French territory off Canada with a population of 6000 people, and Lesotho (50%), one of the poorest countries in Southern Africa. Sri Lanka was hit with a 44% reciprocal tariff. In dollar terms, Sri Lanka’s goods trade deficit with the United States was very small (US$ 2.9 billion in 2025) when compared to those of China (US$ 295 billion in 2024) or Vietnam (US$ 123 billion in 2024).

Though the adverse impact of US additional ad valorem duty has substantially reduced due to the recent US Supreme Court decision on reciprocal tariffs, the turbulence in the US market would continue for the foreseeable future. The United States of America is the largest market for Sri Lanka and accounts for nearly 25% of our exports. Yet, Sri Lanka’s exports to the United States had remained almost stagnant (around the US $ 3 billion range) during the last ten years, due to the dilution of the competitive advantage of some of our main export products in that market. The continued instability in our largest market, where Sri Lanka is not very competitive, doesn’t bode well for Sri Lanka’s economy.

When Elephants Make Love

In rapidly shifting geopolitical environments, countries use proactive anticipatory diplomacy to minimise the adverse implications from possible disruptions and conflicts. Recently concluded Free Trade Agreement (FTA) negotiations between India and the EU (January 2026) and India and the UK (May 2025) are very good examples for such proactive diplomacy. These negotiations were formally launched in June 2007 and were on the back burner for many years. These were expedited as strategic responses to growing U.S. protectionism. Implementation of these agreements would commence during this year.

When negotiations for a free trade agreement between India and the European Union (which included the United Kingdom) were formally launched, anticipating far-reaching consequences of such an agreement on other developing countries, the Commonwealth Secretariat requested the University of Sussex to undertake a study on a possible implication of such an agreement on other low-income developing countries. The authors of that study had considered the impact of an EU–India Free Trade Agreement on the trade of excluded countries and had underlined, “The SAARC countries are, by a long way, the most vulnerable to negative impacts from the FTA. Their exports are more similar to India’s…. Bangladesh is most exposed in the EU market, followed by Pakistan and Sri Lanka.”

So, now these agreements are finalised; what will be the implications of these FTAs between India and the UK and the EU on Sri Lanka? According to available information, the FTA will be a game-changer for the Indian apparel exporters, as it would provide a nearly ten per cent tariff advantage to them. That would level the playing field for India, vis-à-vis their regional competitors. As a result, apparel exports from India to the UK and the EU are projected to increase significantly by 2030. As the sizes of the EU’s and the UK’s apparel markets are not going to expand proportionately, these growths need to come from the market shares of other main exporters like Sri Lanka.

So, “also, when elephants make love, the grass suffers.”

Impact on Sri Lanka

As a small, export dependent country with limited product and market diversification, Sri Lanka will always be vulnerable to what happens in our main markets. Therefore, we must be aware of what is happening in those markets, and prepare ourselves to face the challenges proactively. Today, amid intense geopolitical conflicts, tensions and tariff shifts, countries adopt high agility and strategic planning. If we look at what our neighbours have been doing in London, Brussels and Tokyo, we can learn some lessons on how to navigate through these turbulences.

QR-based fuel quota

Published

on

The introduction of the QR code–based fuel quota system can be seen as a timely and necessary measure, implemented as part of broader austerity efforts to manage limited fuel resources. In the face of ongoing global fuel instability and economic challenges, such a system is aimed at ensuring equitable distribution and preventing excessive consumption. While it is undeniable that this policy may disrupt the daily routines of certain segments of the population, it is important for citizens to recognize the larger national interest at stake and cooperate with these temporary measures until stability returns to the global fuel market.

At the same time, this initiative presents an important opportunity for the Government to address long-standing gaps in regulatory enforcement. In particular, the implementation of the QR code system could have been strategically linked to the issuance of valid revenue licenses for vehicles. Restricting QR code access only to vehicles that are properly registered and have paid their revenue dues would have helped strengthen compliance and improve state revenue collection.

Available data from the relevant authorities indicate that a significant number of vehicles—especially three-wheelers and motorcycles—continue to operate without valid revenue licences. This represents a substantial loss of income to the State and highlights a weakness in enforcement mechanisms. By integrating the fuel quota system with revenue license verification, the government could have effectively encouraged vehicle owners to regularise their documentation while simultaneously improving fiscal discipline.

In summary, while the QR code fuel system is a commendable step toward managing scarce resources, aligning it with existing regulatory requirements would have amplified its benefits. Such an approach would not only support fuel conservation but also enhance government revenue and promote greater accountability among vehicle owners.
