A troubling trend with global echoes and local implications

At a time when biodiversity loss, climate change, and food insecurity dominate international headlines, and sustainable development are at the forefront of global priorities, it seems paradoxical that the systematic study of plants — botany — is quietly disappearing from high school syllabi across the world. Both globally and here in Sri Lanka, botany is gradually being absorbed into broader biology curricula, or worse, omitted altogether, raising serious concerns for the future. This shift is not just a curiosity of education policy; it is shaping a generation that is alarmingly disconnected from the very organisms that sustain life on Earth.

Recent research underscores this concern. A 2023 study published in BMC Biology Education found that only 9% of secondary school biology exam questions across ten countries pertained to plants. Meanwhile, a meta-analysis in New Phytologist (2022) documented declining enrolments in botany and plant taxonomy courses at universities globally, linking it to reduced curricular emphasis in schools.

The global erosion of plant science education

Around the world, educators and scientists have sounded the alarm over what is sometimes called “plant blindness” — the tendency of people, especially urban populations, to overlook plants in favour of more charismatic fauna. Studies in the US, UK, and Australia have documented a steady reduction in botany-specific content in school syllabi. Biology courses overwhelmingly favour human physiology, genetics, and zoology, often relegating plants to a few cursory chapters.

For instance, a 2019 survey of secondary school biology curricula across several OECD (Organisation for Economic Co-operation and Development) countries found that less than 15% of biology syllabus time was dedicated to plant-related topics. Universities report that fewer students choose botany majors, leading to shortages of trained botanists — ironically, just as we need them most to tackle agricultural resilience, forest restoration, and conservation.

The Sri Lankan story: from colonial botany to modern neglect

Sri Lanka’s experience mirrors this global trend but also has a unique historical arc. During the British colonial period, botany was a prominent part of school education. Many early syllabi (e.g. 1902 & 1921 Ceylon Education Codes) included separate subjects on botany and plant classification, reflecting both colonial interests in plantation crops and the global push for natural history education. Students examined local flora, collected specimens, and engaged with plant taxonomy.

By the 1990s, however, reforms gradually merged botany and zoology into a single subject: general biology. While intended to modernise science education, this merger drastically curtailed the depth of plant studies. A glance at our own G.C.E. Ordinary Level and Advanced Level biology syllabi reveals a disproportionate emphasis on human biology. Today, at G.C.E. A/L level, botany is reduced to a handful of chapters on plant histology, physiology, and reproduction, with scant attention to Sri Lanka’s astonishing plant diversity.

Consequences at university level: a shrinking knowledge base

This shift is evident in our undergraduates. A 2021 survey conducted among first-year biology majors at two Sri Lankan universities revealed that fewer than 15% could identify even five common endemic plant species. Their understanding of fundamental plant taxonomy — once the backbone of biological education — was described by lecturers as “abysmal.”

The consequences ripple into higher education and research. Universities now struggle to fill botany specialisations, impacting critical fields such as conservation biology, plant systematics, and herbal pharmacognosy. Ironically, this occurs as Sri Lanka grapples with forest degradation and the need to sustainably harness its rich endemic flora.

Botany as a stand-alone subject, once offered alongside zoology, has all but disappeared from school syllabi. At A/L level, botany is merely a component within the broader biology syllabus. Consequently, fewer students develop a deep interest or expertise in plant sciences before entering university, affecting enrolment in specialising Honours Degrees in botany, plant biotechnology, and related fields.

The global plant blindness problem

This is not a uniquely Sri Lankan failing. International scholars warn of “plant blindness,” a term coined by Wandersee & Schussler, describing how humans fail to notice plants in their environment and undervalue their importance. A 2022 paper in Science Advances reported that biology textbooks worldwide devote less than 10% of pages to plants, despite plants constituting over 80% of Earth’s biomass.

Why does it matter?

Plants underpin life on Earth. They produce oxygen, regulate climate, stabilise soils, provide food, medicine, clothing, and shelter. In Sri Lanka, where over 1,400 plant species are endemic and traditional knowledge of medicinal plants is rich, understanding our flora is not merely academic — it is part of our cultural and economic heritage. Moreover, traditional knowledge systems, from Ayurveda to local agroforestry practices, hinge on a deep familiarity with plants. When the next generation is not taught to recognise even the common species around them, we sever links to this ecological and cultural inheritance.

Neglecting plant science education threatens our ability to conserve biodiversity, manage ecosystems, and innovate in agriculture and herbal industries. With climate variability already affecting tea, coconut, and rice yields, we need more — not fewer — young minds trained in plant science.

A call to restore balance

Internationally, there is growing recognition of this gap. Organizations such as the Botanical Society of America and campaigns like “Plant Love Stories” work to re-engage young people with plants. Initiatives such as the “Plants in Our World” curriculum in Europe and botanic garden outreach programs aim to restore balance. Some countries are revising curricula to integrate more ecological and plant-based studies.

Sri Lanka too must consider revising syllabi to reinstate rigorous botany components — from plant anatomy and systematics to field-based identification exercises. Reintroducing school herbaria, medicinal plant gardens, local flora surveys, and digital plant ID tools could stimulate interest. Universities could partner with schools for hands-on taxonomy workshops, reconnecting students with the extraordinary diversity outside their classroom doors.

In conclusion

As we confront environmental challenges that are inherently tied to plants — from deforestation to food insecurity — we cannot afford a generation indifferent to botany. Addressing this educational blind spot is essential not only for scientific advancement but for safeguarding our ecosystems and cultural legacy.

If we truly aim for a sustainable future, it is time to bring botany back to the centre stage of our classrooms, both globally and right here in Sri Lanka.

The Indian Ocean as a zone of peace

Published

on

Late Prime Minister Sirimavo Bandaranaike

Recently, we all held our breath when a conflict began to develop very close to Sri Lanka. The sinking of the Iranian frigate IRIS Dena in the Indian Ocean took place in international waters about 30 miles from Sri Lanka’s southern coast. As the whole world watched, the President and the Government of Sri Lanka were faced with a humanitarian crisis. A second Iranian ship was also in distress and needed assistance. Although Sri Lanka’s maritime history dates back to 5th

Century BCE, this type of geopolitical crisis has been very rare.

Sri Lanka considered it the moral responsibility of the country to help out those affected during this geopolitical crisis. It chose to activate its role as a custodian of the Indian Ocean. Perhaps, not many individuals are aware of Sri Lanka’s historical role in calling on the United Nations to declare the Indian Ocean a Zone of Peace. In 1971, under the leadership of the first woman prime minister of the world, Sirimavo Bandaranaike, Sri Lanka, together with Tanzania brought forth a resolution to the 26th Session of the General Assembly of the United Nations to declare the Indian Ocean a “Zone of Peace.” This was done to avoid it being used by superpower rivalries to gain military control of the region. Sri Lanka’s Ambassador Shirley Amarasinghe, the President of the 31st general Assembly of the UN was responsible for working on this resolution as with others dealing with the “Law of the Sea”.

The shadow of a Truman moment in the Iran war

Published

on

Wars often produce moments when leaders feel compelled to seek a decisive stroke that will end the conflict once and for all. History shows that such moments can generate choices that would have seemed unthinkable only months earlier. When Harry S. Truman authorised the atomic bombings of Hiroshima and Nagasaki in 1945, the decision emerged from precisely such wartime pressures. As the conflict involving the United States, Israel and Iran intensifies today, the world must ensure that a similar moment of desperate calculation does not arise again.

The lesson of that moment in history is not that such weapons can end wars, but that once the logic of escalation begins to dominate wartime decision-making, even the most unthinkable options can enter the realm of strategic calculation. The mere possibility that such debates could arise is reason enough for policymakers everywhere to approach the present conflict with extreme caution.

As the war drags on, both Donald Trump and Benjamin Netanyahu will face mounting pressure to produce decisive results. Wars rarely remain confined to their original scope once expectations of rapid victory begin to fade. Political leaders must demonstrate progress, military planners search for breakthroughs, and public narratives increasingly revolve around the need for a conclusive outcome. In this environment, media speculation about “exit strategies” or “off-ramps” for Washington can unintentionally increase pressure on decision-makers. Even well-intentioned commentary can shape the climate in which leaders make decisions, potentially nudging them toward harder, more dramatic actions.

Neither the United States nor Israel lacks the technological capability associated with advanced nuclear arsenals. The nuclear arsenals of advanced powers today are far more sophisticated than the devices used in 1945. While their existence is intended primarily as deterrence, prolonged wars have historically forced strategic communities to examine every available option. Even the discussion of such possibilities is deeply unsettling, yet ignoring the pressures that produce such debates can be dangerous.

For that reason, policymakers and societies on all sides must recognise the full range of choices that prolonged wars can place before leaders. For Iran’s leadership and its wider strategic community, absorbing this reality may be essential if catastrophic escalation is to be avoided. From Tehran’s perspective, the conflict may well be seen as existential. Yet history also shows that wars framed as existential struggles can generate the most dangerous strategic decisions.

The intellectual climate in Washington has also evolved. A number of influential voices in Washington now argue that the United States has become excessively risk-averse and that restoring global credibility requires a more assertive posture. Such arguments reflect a broader shift toward the language of renewed deterrence and strategic competition. Yet this very logic can make it politically harder for leaders to conclude conflicts without visible demonstrations of strength.

The outcome of this conflict will also be watched closely by other major powers. In 1945, the atomic decision was shaped not only by the desire to end a brutal war but also by the strategic message it sent to rival states observing the emergence of a new geopolitical era. Today, other significant powers will similarly draw lessons from how the United States manages both the conduct and the conclusion of this conflict.

This is why cool judgment is essential at this stage of the war. Whether the original decision to go to war was wise or ill-advised is now largely beside the point. Once a conflict has begun, the overriding priority must be to prevent escalation into something far more dangerous.

In such moments, the international system can benefit from the quiet diplomacy of actors that retain a degree of strategic autonomy. Among emerging nations, India stands out as a major emerging power in this regard. Despite its energy dependence on the Gulf and deep economic engagement with the United States, India has consistently demonstrated a capacity to maintain independent channels of communication across geopolitical divides.

This unique positioning may allow New Delhi to explore, discreetly and without public fanfare, avenues for de-escalation with Washington, Tel Aviv and Tehran alike. At moments of heightened tension in international politics, the world sometimes requires what might be called an “adult in the room”: a state capable of engaging all sides while remaining aligned exclusively with none.

If the present conflict continues to intensify, the value of such diplomacy may soon become evident. The most important lesson from 1945 is not only the destructive power of nuclear weapons but the pressures that can drive leaders toward choices that later generations struggle to comprehend. History shows that when wars reach their most desperate phases, restraint remains the only safeguard against catastrophe.

Practicality of a trilingual reality in Sri Lanka

Published

on

Dr. B.J.C. Perera (Dr. BJCP) in his article ‘Language: The symbolic expression of thought’ (The island 10.03.2026) delves deeper into an area that he has been exploring recently – childhood learning. In this article he writes of ‘a trilingual Sri Lanka’, reminding me of an incident I witnessed some years ago.

Two teenagers, in their mid to late teens, of Muslim ethnicity were admitted to the hospital late at night, following a road traffic accident. They had sustained multiple injuries, a few needing surgical intervention. One boy had sustained an injury (among others) that needed relatively urgent attention, but in itself was not too serious. The other had also sustained a few injuries among which one particular injury was serious and needed sorting out, but not urgently.

After the preliminary stabilisation of their injuries, I had a detailed discussion with them as to what needed to be done. Neither of them spoke Sinhala to any extent, but their English was excellent. They were attending a well-known international school in Colombo since early childhood and had no difficulty in understanding my explanation – in English. The boys were living in Colombo, while their father would travel regularly to the East (of Sri Lanka) on business. The following morning, I met the father to explain the prevailing situation; what needs to be done, urgency vs. importance, a timeline, prioritisation of treatment, possible costs, etc.

Doctor’s dilemma

The father did not speak any English and in conversation informed me that he had put both his boys into an International School (from kindergarten onwards) in order to give them an English education. The issue was that the father’s grasp of Sinhala was somewhat rudimentary and therefore I found that I could not explain the differences in seriousness vs, urgency and prioritisation issues adequately within the possible budget restrictions. This being the case and as the children understood exactly what was needed, I then asked the sons to ‘educate’ the father on the issues that were at hand. The boys spoke to their father and it was then that I realised that their grasp of Tamil was the same as their father’s grasp of Sinhala!

In the end I had to get down a translator, which in this case was a junior doctor who spoke Tamil fluently; explained to him what was needed a few times as he was not that fluent in English, certainly less than the boys, and then getting him to explain the situation to the father.

What was disturbing was having related this episode at the time to be informed that this was not in fact not an isolated occurrence. That there is a growing number of children that converse well in English, but are not so fluent in their mother tongue. Is English ‘the mother tongue’ of this ‘new generation’ of children? The sad truth is no and tragically this generation is getting deprived of ‘learning’ in its most fundamental form. For unfortunately, correct grammar and syntax accompanied with fluency do not equal to learning (through a language). It is the natural process of learning two/three languages (0 to 5 years) that Dr. BJCP refers to as being bilingual/trilingual and is the underlying concept, which is the title of Dr. BJCP’s article ‘Language: The symbolic expression of thought’.

“Introduction into society”

It is critical to understand at a very deep level the extent and process of what learning in a mother tongue entails. The mother’s voice is arguably the first voice that a newborn hears. Generally speaking, from that point onwards till the child is ‘introduced into society’ that is the voice he /she hears most. In our culture this is the Dhorata wedime mangalyaya. Till then the infant gets exposed to only the voices of the immediate /close family.

Once the infant gets exposed to ‘society’ he /she is metaphorically swimming in an ocean of language. Take for example a market. Vendors selling their wares, shouting, customers bargaining, selecting goods, asking about the quality, freshness, other families talking among themselves etc. The infant is literally learning/conceptualizing something new all the time. This learning process happens continuously starting from home, at friends/relatives’ houses, get-to-gathers, festivals, temples etc. This societal exposure plays a dominant role as the child/infant gets older. Their language skills and vocabulary increase in leaps and bounds and by around three years of age they have reached the so-called ‘language explosion’ stage. This entire process of learning that the child undergoes, happens ‘naturally and effortlessly’. This degree of exposure/ learning can only happen in Sinhala or Tamil in this country.

Second language in chilhood

Learning a second language in childhood as pointed out by Dr BJCP is a cognitive gift. In fact, what it actually does is, deepens the understanding of the first language. So, this-learning of a second language- is in no way to be discouraged. However, it is critical to be cognisant of the fact that this learning of the second language also takes place within a natural environment. In other words, the child is picking up the language on his own. As readily illustrated in Dr. BJCP’s article, the home environment where the parents and grandparents speak different languages. He or she is not being ‘forcefully taught’ a language that has no relevance outside the ‘environment in which the second language is taught’. The time period we (myself and Dr. BJCP) are discussing is the 0 to 5-year-old.

It does not matter whether it is two or three languages during this period; provided that it happens naturally. For as Dr. BJCP states in his article ‘By age five, they typically catch up in all languages…’ To express this in a different way, if the child is naturally exposed to a second /third language during this 0 to 5-year-old period, he /she will naturally pick it up. It is unavoidable. He /she will not need any help in order for this to happen. Once the child starts attending school at the age of 5 or later, then being taught a second language formally is a very different concept to what happens before the age of 5.

The tragedy is parents, not understanding this undisputed significance of ‘learning in/a mother tongue’, during the critical years of childhood-0 to 5; with all good and noble intentions forcefully introduce their child to a foreign tongue (English) that is not spoken universally (around them) i. e., It is only spoken in the kindergarten; not at home and certainly nowhere, where the parents take their children.

Attending school

Once the child starts attending school in the English medium, there is no further (or minimal) exposure to his /her mother tongue -be it Sinhala or Tamil. This results in the child losing the ability to converse in his/her original mother tongue, as was seen earlier on. In the above incident that I described at the start of this article, when I finally asked the father did he comprehend what was happening; his eyes filled with tears and I did wonder was this because of his sons’ injuries or was it because his decisions had culminated in a father and a son/s who could no longer communicate with each other in a meaningful way.

Dr BJCP goes on to state that in his opinion ‘a trilingual Sri Lanka will go a long way towards the goals and display of racial harmony, respect for different ethnic groups…’ and ‘Then it would become a utopian heaven, where all people, as just Sri Lankans can live in admirable concordant synchrony, rather than as a splintered clusters divided by ethnicity, language and culture’. Firstly, it must be admitted from the aspect of the child’s learning perspective (0 to 5 years); an environment where all three languages are spoken freely and the child will naturally pick up all three languages (a trilingual reality) does not actually exist in Sri Lanka.

However, the pleasant practical reality is that, there is absolutely no need for a trilingual Sri Lanka for this utopian heaven to be achieved. What is needed is in fact not even a bilingual Sri Lanka, but a Sri Lanka, where all the Sinhalese are taught Tamil and vice versa. Simply stated it is complete lunacy– that two ethnic communities that speak their own language, need to learn another language that is not the mother tongue of either community in order to understand one another! It is the fact that having been ruled by the British for over a hundred years, English has been so close to us, that we are unable to see this for what it is. Imagine a country like Canada that has areas where French is spoken; what happens in order to foster better harmony between the English and French speaking communities? The ‘English’, learn to speak French and the ‘French’ learn to speak English. According to the ‘bridging language theory of Sri Lanka’, this will not work and what needs to happen is both communities need to learn a third language, for example German, in order to communicate with one another!

Learning best done in mother tongue

eiterating what I said in my previous article – ‘Educational reforms: A Perspective (The Island 27.02.2026) Learning is best done in one’s mother tongue. This is a fact, not an opinion. The critical thing parents should understand and appreciate is that the best thing they can do for their child is to allow/encourage learning in his/her mother tongue.

This period from 0 to 5 years is critically important. If your child is exposed naturally to another language during this period, he /she will automatically pick it up. There is no need to ‘forcefully teach’ him /her. Orchestrating your child to learn another language, -English in this instance- between the ages of 0 to 5 at the expense of learning in his /her mother tongue is a disservice to that child.
