SpaceX prepares for the Great Filter – but why?
What’s Elon Musk’s gameplan to get humans to thrive in the universe all about?
Two weeks ago, Ed Publica did a news story on Elon Musk’s tweet. It sure was a headline topic in itself. “We are mapping out a game plan to get a million people to Mars,” posted Musk. “Civilization only passes the single-planet Great Filter when Mars can survive even if Earth supply ships stop coming.”
Press releases that came in the wake of the tweet, never did engage with Musk’s invocation of – the Great Filter – which as the astronomer Seth Shostak once stated, a ‘variant on the Fermi paradox’.
The Fermi paradox was borne out of an idea proposed by the enigmatic 20th century theoretical physicist, Enrico Fermi, who posed a profound, philosophical question: If an intelligent civilization were capable of space travel, and extraterrestrial life existed, then where are they?
The question itself was a paradoxical idea. Either of course, aliens don’t exist – or if they do, then they’re hiding in plain sight, not wanting to be contacted. Perhaps in the latter case, aliens want to avoid being colonized or wiped extinct by a civilization with superior technology. No one knows what the answer is. We don’t know yet if it even is a paradox with an answer.
But the Great Filter theory, proposed by an economist, Robin Hanson in 1998 makes an interesting argument that offers a possible resolution against the Fermi paradox. Maybe life is uncommon, or can easily go extinct. There can be some factors at play to stop a civilization from thriving and spawn a population to safeguard it.
Maybe humanity’s destined to live, and then die on earth – only to live on Mars, until every resource exhausts and human genes are ferried to distant exoplanets to hopefully spawn and recreate humanity there. Or perhaps humanity’s alone amongst the trillions of stars in the universe, because someone has to make the first step to show how difficult it is for life to thrive.

How feasible is this?
Musk’s prophetic vision is more his vision for humanity – reminiscent in science fiction novels and films.
There’s a line from the movie Interstellar (2014), when Michael Caine, playing an astrophysicist, says, ‘We’re not meant to save the world, we’re meant to leave it.’ In the movie, earth gets plagued by crop blight, and people starve to death when food resources are hard to sustain. Although the problem was foreseeable, we were too late to act on it. And that was the main driver of the plot. Astronauts were dispatched into a wormhole and tunnel through into a different galaxy light years away. Humanity was doomed, and so the astronauts prepared human embryos to take our place and be the Adam and Eves of their species.
The Great Filter and the Fermi paradox are at best a useful thinking exercise about the myriad ways human imagination really works.
Musk’s idea to colonize Mars makes some sense in that it’s about taking a small step to demonstrate we can demonstrate a necessary first step of survival.
But then space is cruel and indifferent. The Martian atmosphere is completely thin, with almost zero atmospheric pressure. It’s not even about the carbon dioxide in what’s left in that atmosphere – there’s just barely any atmosphere there. Musk probably is aware of this, given he has a physics background!
For instance, how do we pressurize a whole planet? The optimism is that technology can circumvent these problems.
This technology, possibly in a few decades, can seem like ‘magic’ to us. The Great Filter and the Fermi paradox are at best a useful thinking exercise about the myriad ways human imagination really works.
And until we demonstrate basic physics that works in its favor, aren’t these just wishful fantasies?
For instance, how can SpaceX ‘gameplan’ Mars’ colonization, if the company doesn’t itself survive the Great Filter test? Who else in the world is taking this seriously apart from Elon Musk?
‘Colonizing’ space
Musk’s gameplan invites more questions, since there’s barely any discussion that he leads on it.
Musk is polarizing to his critics, who question the need for expensive space exploration programs that have no direct benefit on our economy.
Musk’s usage of the term ‘colonization’ can be seen to resonate with the sentiment in the 15th century when the West discovered the rest of the world through the sea-route. However, it didn’t fare well for the rest of the world. One notable example is when Christopher Columbus, ‘discovered’ North America, when he was in search of India – he and his men began the subjugation of Native Americans.

Meanwhile, the Portuguese voyager Vasco da Gama arrived at the shores of India, in Kozhikode. That opened up routes for vessels of the East India Company from across Europe to trade – and then colonize Indians.
I’m not suggesting Musk has nefarious plans at play. However, what’s the chance that future government policies somehow get blindsided, or ignorant of advice from experts outside science on the political implications of space exploration?
And what better ‘gameplan’ can there really be if it starts with experts from a diversity of fields huddling together for an enlightening discussion?

India’s Young Dream Is Changing. Are We Ready?
From skills and employment to entrepreneurship, purpose and global aspirations, India’s youth are redefining what a successful future looks like.
India’s young generation is navigating a changing job market, skills gap, career pressures and global ambitions. What can India do to build a more secure and purposeful future for its youth?
India’s youth are shaping the destiny of the modern nation state, and the country’s demographic dividend is often cited as its greatest economic advantage. Yet in the post-pandemic era, that advantage sits uneasily alongside a labour market being reshaped by technology, and alongside growing anxieties about work-life balance. Degrees and formal qualifications matter less than they once did; skills now decide who gets hired. The conventional career ladder is giving way to entrepreneurship, and local ideas are finding global audiences through a digitally connected world.
India’s Youth Face a Changing Job Market
Even in the age of the internet, young people in India’s remote villages need more than connectivity to compete for jobs. Better English communication, soft skills training and technical know-how could do much to empower farmers and young people in rural areas. The Union government’s Deen Dayal Upadhyaya Grameen Kaushalya Yojana, aimed at upskilling rural youth, is a step in this direction, but the scheme’s reach and impact deserve closer scrutiny than they currently receive.
Reducing unemployment cannot be the government’s job alone. It calls for a collective effort: a social reform movement that goes beyond electoral politics and pushes for constructive dialogue on the concerns of young people. Independent media has a role here too, in pursuing solutions-driven journalism, without fear or favour, that surfaces localised ideas for financial security and wellbeing.
Dignity of Work, Voice in Parliament
A social renaissance built on universal access to education and life-skills training, paired with a national minimum wage across sectors, would restore a basic sense of dignity to every working citizen. A national mission on youth concerns, one that cuts across party lines, is overdue. Greater youth representation in Parliament could combine the experience of older leaders with the energy of a younger population, in service of the Gandhian ideal of Sarvodaya, the upliftment of all through equal access to education, services and mentorship.
Life After the Civil Services Exam
Many young Indians aspire to the civil services, and a whole industry of coaching academies has grown around that aspiration. But only a small fraction of aspirants clear every stage of the examination and enter the service. For the rest, failure need not be an ending. Careers in media, academia and research are open to those willing to look beyond government employment. Aspirants would do well not to pour years into preparation alone; short courses and internships alongside exam preparation build a resume rich in the domains they actually care about, whatever path they eventually take.
Beyond the Rat Race
The pursuit of social prestige, at the expense of everything else, breeds burnout and a routine that feels mechanical rather than meaningful. A professional life worth having offers more than financial security; it offers peace of mind and a sense of contentment. That kind of self-reliance and purpose is possible, but it requires young people to define success on their own terms rather than borrow someone else’s definition of it.
The same is true of attention. Shrinking attention spans, a by-product of life on the smartphone, are a legitimate cause for concern in a hyper-connected era. A weekly or monthly digital holiday, however modest, can restore clarity of thought and make room for the kind of offline interaction that a screen cannot replace.
An Aspirational, Global Generation
India’s youth remain aspirational, drawn to opportunities in Europe, the Gulf and North America, and increasingly to frontiers beyond Earth. Geopolitical tensions in the Middle East, the war in Ukraine and a volatile global economy have not dimmed that ambition. Policymakers could do more to meet it at home, by building India into a genuine hub for higher education, with international students, faculty and university campuses. That transformation has already begun in pockets. What is missing is a coherent, pan-Indian policy to carry it forward, and with it, India’s aspiration to become a genuine centre of global learning.

From Soil to Profit: How Organic Turmeric Changed the Fortunes of a Tribal Farming Family
A tribal farming family in Rajasthan’s Banswara district improved its livelihood through organic turmeric farming, value addition and diversified agriculture.
A farming couple in Rajasthan’s Banswara district transformed their livelihood through organic turmeric farming, value addition and a nutrition garden, demonstrating how sustainable agriculture and crop diversification can strengthen rural incomes and food security.
In India’s tribal regions, farming has never been merely a means of livelihood—it has been a way of life carried forward across generations. Yet changing markets, rising input costs and climate uncertainty are encouraging some farmers to combine traditional knowledge with new approaches.
Mangalsingh Ganaga, a farmer from Phalwa village in Rajasthan’s Banswara district, is one such example. By introducing organic turmeric cultivation alongside his existing crops and adding value through processing, he improved his household income while demonstrating how sustainable farming can create new opportunities for smallholders.
Organic Turmeric Farming And The Turnaround
Turmeric has long been an inseparable part of Indian kitchens and Ayurvedic medicine. Rich in curcumin—the compound responsible for its distinctive yellow colour and medicinal properties—it has traditionally been used to treat ulcers, digestive disorders and a range of other ailments. Because turmeric is used in almost every Indian household, demand remains steady throughout the year, making it an attractive crop for farmers who have access to quality seed, organic cultivation techniques and local markets.
Building on Traditional Farming
Phalwa village, located in Anandpuri tehsil of Banswara district, is a predominantly tribal settlement where agriculture and livestock remain the backbone of rural livelihoods.
Mangalsingh cultivates six bighas of irrigated land, growing maize, black gram, sesame and patharia rice during the kharif season, followed by chickpea and wheat in the rabi season. His household also maintains four buffaloes, three cows, two bullocks and five goats, providing milk, farm labour and a steady supply of organic manure.
Although he had long wanted to experiment with natural farming methods, he lacked the technical guidance to do so.
“I had always wanted to try something new alongside my traditional farming, but I didn’t know where to begin. Once I learned about organic farming and received proper guidance, I finally had the confidence to experiment on my own land,” says Mangalsingh.
The turning point came when he met Lalita Makwana, a community facilitator with VAAGDHARA, a Banswara-based organisation working with tribal farming communities. Through the Gram Swaraj Self-Help Group, he was introduced to VAAGDHARA’s Sachchi Kheti (True Farming) programme, which trains farmers in organic cultivation and sustainable agricultural practices.
Learning Organic Farming
Through VAAGDHARA’s Farmer Field School, Mangalsingh gradually reduced his dependence on chemical fertilisers and pesticides, replacing them with farmyard manure and dashparni extract, a traditional bio-pesticide prepared by fermenting ten bitter or pungent leaves—such as neem and custard apple—with cow urine and cow dung.
Rather than replacing his existing crops, he adopted a mixed-cropping system by cultivating maize alongside turmeric. The approach not only reduced production risks but also created an additional income stream from the same piece of land.

To maximise returns, he moved beyond selling raw turmeric. Instead, he processed part of his harvest into turmeric powder and packaged it for sale, allowing him to secure a substantially higher market price.
Adding Value Increased Income
Under the Sachchi Kheti programme, Mangalsingh received five kilograms of turmeric seed, which he planted on a 20 × 25-foot plot using approximately 400 kilograms of cow-dung manure from his own livestock. Technical guidance throughout the cultivation cycle—from sowing to harvesting—came through VAAGDHARA’s Farmer Field School.
He sowed the crop in the first week of July 2025 and harvested it in May the following year, producing 60 kilograms of turmeric from the initial five kilograms of seed.
Rather than selling the entire harvest as raw produce, he adopted a value-addition strategy:
>> 20 kg of raw turmeric sold at ₹150 per kg, earning ₹3,000
>> 30 kg processed into turmeric powder and sold at ₹400 per kg, earning ₹12,000
>> 10 kg retained for household consumption and seed for the next planting season
The turmeric generated gross sales of ₹15,000. Because the seed was supplied through the programme and the manure came from his own livestock, cash input costs remained relatively low. He also found ready buyers without travelling to distant markets, as word spread locally about the chemical-free turmeric.
A Nutrition Garden Brings Additional Income
The family’s transformation did not end with turmeric.
Mangalsingh’s wife, Shantidevi Ganaga, received a vegetable seed kit through VAAGDHARA’s Poshan Vatika (Nutrition Garden) initiative. The kit included seeds for okra, cowpea, bottle gourd, ridge gourd, tomato, brinjal, cluster beans, fenugreek, spinach and chilli.
The garden supplied fresh vegetables for the family’s own consumption while generating an additional income through surplus sales.
“The nutrition garden not only improved our family’s diet but also gave me an income of my own. Selling the surplus vegetables helped strengthen our household finances,” says Shantidevi.

Over the course of the year, she earned around ₹60,000 by selling vegetables—making a significant contribution to the family’s overall income while improving household nutrition.
Diversification Builds Resilience
Both Mangalsingh and Shantidevi continue to participate in VAAGDHARA’s Farmer Field School, where community facilitators provide technical guidance while encouraging farmers to exchange experiences and learn from one another.
The family’s journey highlights a broader lesson for smallholder agriculture: diversification strengthens resilience. Grain crops, organic turmeric, livestock and vegetables together provide multiple income streams, reducing dependence on any single crop or growing season.
Programmes such as Sachchi Kheti and the Nutrition Garden initiative aim not only to improve farm incomes but also to encourage environmentally sustainable agriculture that supports long-term soil health and reduces dependence on chemical inputs.
Lessons Beyond One Farm
For Mangalsingh and Shantidevi Ganaga, organic farming has become more than a change in cultivation practices—it has become a pathway to greater economic security and improved food security.
Their experience illustrates how technical guidance, value addition and diversified farming can work together to strengthen rural livelihoods. Whether such success can be replicated more widely will depend on sustained farmer training, market access and continued support for sustainable agriculture. But for one tribal farming family in southern Rajasthan, a small turmeric plot and a nutrition garden have already demonstrated how innovation rooted in local knowledge can deliver lasting change.

How India’s Agrarian Crisis Is Making Nutritious Food Unaffordable
India’s agrarian crisis is reducing farmer incomes while making healthy diets increasingly expensive. Here’s why India’s food system needs urgent reform.
India’s agrarian crisis is shrinking farmer incomes while driving up the cost of healthy diets, exposing deep flaws in the country’s food system and nutrition security.
When the figures are carefully unpacked, one thing becomes unmistakable: Indian agriculture is passing through a deep and prolonged crisis. The sector is no longer a reliable source of income, and government support has not reached farmers in the measure needed to restore profitability. The farmer who, a few decades ago, owned his own soil is today gradually turning into a daily-wage labourer. Of a farming family’s total monthly earnings, barely one-third now comes directly from agriculture; the remaining share, nearly two-thirds, has to be made up through government or private jobs, wage labour, or small enterprises. In other words, farming alone is no longer enough to run a household.
How India’s Agrarian Crisis Is Making Nutritious Food Unaffordable
What is more worrying is that, even as the sector remains under pressure, the number of new entrants is rising rather than falling — and most are joining not as landowning farmers but as farm labourers. As landholdings are divided into smaller and smaller fragments, income from farming declines rapidly, forcing families to depend increasingly on non-agricultural sources to survive. This is reflected in suicide statistics too: of the total agricultural suicides recorded in 2023, the latest year for which the National Crime Records Bureau has released data, more than half — at least 56.5 per cent — were of farm labourers. This is not a sudden trend; it has been consistent for years. Of the 10,786 farm-sector suicides recorded that year, 4,690 were landowning farmers or cultivators, while 6,096 were farm labourers — that is, workers who own no land in their name, hold no crop insurance cover, and have no support to fall back on if the season fails. It is precisely this group of daily-wage workers that has today moved to the very centre of the agrarian crisis.
A survey by the National Bank for Agriculture and Rural Development (NABARD) paints a similarly stark picture: over the past five years, nearly 30 per cent of farming families reported crop losses caused by untimely rain, pest and disease attacks, cyclones or drought, and 12 per cent suffered unexpected drops in market prices. Faced with these shocks, families were left with only two options — exhaust their savings or borrow from moneylenders. The reality is so stark that, per NABARD’s All India Rural Financial Inclusion Survey (NAFIS) 2021-22, covering the five-year window from 2016-17 to 2021-22, the average farming household is left with a monthly surplus of just ₹1,951 after covering its expenses — and it is precisely out of this gap that the cycle of debt is born.
The average debt on a farming household stood at ₹91,231, marginally higher than the ₹89,074 average for non-farming households. The Parliamentary Standing Committee on Agriculture, Animal Husbandry and Food Processing has said the situation demands close monitoring and precisely targeted interventions, so that farmers can sustainably bear the burden of their debt while continuing to invest in agriculture. The committee stated that the department concerned must ensure farmers do not get trapped in an unbearable cycle of debt, and that the schemes designed for them actually deliver benefits on the ground.
And this crisis will not stop here. A powerful super El Niño is taking shape, and weather experts fear it may disrupt the coming monsoon. Farmers already entering the new season in loss, and under the weight of debt, have little capacity left to absorb another shock. In this new era of shifting climate, providing farmers with a coherent, far-sighted policy framework is not a lofty demand — it is the bare minimum.
The Rising Cost of Nutrition
The crisis in the fields echoes directly in urban kitchens, and today the sharpest edge of inflation is falling on the ordinary person’s plate. In India, a nutritious and balanced diet is becoming more expensive every year, moving further out of reach for crores of families. According to the UN’s latest report, The State of Food Security and Nutrition in the World 2026, the per capita cost of a healthy diet in India has risen by more than 48 per cent since 2017. The minimum cost of a daily balanced diet for an average Indian, which stood at $2.77 (PPP) in 2017, reached $4.11 in 2025 — a rise of roughly 34 per cent compared to 2021, when the figure for India stood at $3.07 (PPP). Purchasing power parity (PPP) does not depend on currency exchange rates alone; it also accounts for local prices of goods and services in a given country, and so more truly reflects the burden falling on an ordinary person’s pocket.
The average global per capita cost of a healthy diet has risen from $2.94 (PPP) in 2017 to $4.28 in 2025, an increase of nearly 46 per cent
This rise in prices hits poor and economically weaker families hardest, because the moment prices rise, it is nutrient-rich foods such as fruits, vegetables, milk and eggs that first begin disappearing from their plates. If a healthy diet continues to remain this expensive, the path to a balanced diet will become even harder for families already struggling with malnutrition. According to the definition set by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO), a diet can be called healthy only when it simultaneously provides the body with sufficient energy, essential nutrients, variety and balance — mere fullness of the stomach is not the criterion.

The global picture is not very different. The average global per capita cost of a healthy diet has risen from $2.94 (PPP) in 2017 to $4.28 in 2025, an increase of nearly 46 per cent. The situation among India’s South Asian neighbours is even more severe than India’s own. In Bhutan, this cost has reached $6.17, a rise of 49 per cent compared to 2017. In Bangladesh it stands at $4.59 with a 48.5 per cent rise, in Sri Lanka at $5.21 with a 35 per cent rise, in Pakistan at nearly $3.94 with roughly a 33 per cent rise, and in Nepal at $4.19 with a 26 per cent rise. In other words, India’s cost is higher than Pakistan’s but lower than Nepal’s, Bangladesh’s, Sri Lanka’s and Bhutan’s. Yet it must not be forgotten that in a country with as vast a population as India, even a small rise in cost can have a massive impact on the plates of millions upon crores of households.
There is, however, one reassuring point: the number of people worldwide unable to afford a healthy diet has declined from 297 crore (37.4 per cent) in 2021 to 269 crore (32.7 per cent) in 2025. Even so, nearly one in every three people in the world today still cannot afford the cost of nutritious food, and it is the African continent that is scorched worst in this regard, where 66.6 per cent of the population finds a healthy diet beyond reach.
It is also worth understanding exactly where the larger share of the cost goes. The greatest expense falls on fruits, vegetables, milk, eggs, meat and other fresh and animal-based foods, while grains such as rice and wheat remain comparatively cheap. It is precisely during the journey from farm to consumer — through processing, transport, storage, cold chains and wholesale distribution — that the bulk of the cost gets added. As much as 70 to 75 per cent of the total amount a consumer pays for their diet is spent purely within this middle chain. The result is that the farmer does not receive adequate reward for his labour, and the consumer too does not get produce at a fair price — both sides end up at a loss.
Taking the example of poor households in India, staple grains such as rice and wheat are easily available through government schemes or subsidised markets. But the prices of pulses, green vegetables, fruits and milk — the very foods that give the body real strength and immunity — have risen so much that they are slipping beyond the monthly budget of an ordinary family. The outcome is that even as malnutrition and anaemia persist in the country on one hand, the inability to afford nutritious food is growing on the other. This makes one thing entirely clear: merely supplying grain is not enough; the real test lies in delivering nutrient-rich components such as fruits, vegetables, pulses, milk and eggs to every plate at affordable rates. For this, irrigation, cold chains, research, food processing and the supply chain will all need to be strengthened, while also curbing the wastage of food.
The FAO has issued one more warning in its report: that tensions in the Strait of Hormuz and an effective El Niño persisting until the end of 2026 could together place additional strain on global food and fertiliser prices in the period ahead. According to the organisation’s Chief Economist, Máximo Torero Cullen, the real crisis facing the world is not a shortage of food but the rising cost of nutritious diets, and that boosting local production could bring this cost down significantly.
It must be kept in mind that if nutritious food keeps slipping beyond the reach of the ordinary person, the consequences will not remain confined to hunger alone — they will cast their shadow over children’s growth, women’s health, working capacity and the country’s overall economic productivity. This malnutrition will keep hollowing out bodies from within, generation after generation. Therefore, the goal before India can no longer remain limited merely to “food for all”; it must become “nutritious food for all.” Local production, a strengthened supply system and nutrition-centred policies have today become the greatest need of the hour.
The suicide of a farmer in the field and the vanishing nutrition from a child’s plate — these two events may appear separate on the surface, but their roots lie buried in the same systemic failure
Vanishing Diversity on Children’s Plates
It is said that the habits that take root on a child’s plate in early childhood go on to shape the direction of health for an entire lifetime. Yet today, essential components such as fruits, vegetables, pulses and dry fruits are gradually vanishing from the plates of crores of children across the world. This reality has come to light through an extensive study conducted by researchers at Tufts University and published in the journal BMJ Global Health. Analysing data from more than 1,200 dietary surveys conducted across 185 countries between 1990 and 2018, the study assessed the consumption, among children and adolescents from birth to nineteen years of age, of five plant-based food groups: fruits, non-starchy vegetables, starchy vegetables, pulses, and nuts and seeds. According to the researchers, these components are important not only for physical growth but equally for learning ability, mental agility and protection from many diseases later in life, and yet most children are eating far fewer fruits and vegetables than experts recommend.
The suicide of a farmer in the field and the vanishing nutrition from a child’s plate — these two events may appear separate on the surface, but their roots lie buried in the same systemic failure. The farmer does not get a fair return for his sweat, and the consumer does not get the nutrition he needs on his plate, and it is the chain standing between these two ends that keeps reaping the greatest profit. As long as this imbalance within the chain remains uncorrected, this cyclical curse will keep returning every year in a new form — sometimes in the shape of a farmer in the field, and sometimes in the shape of a malnourished child.
