< Back to Issue 7 Staying at the Top of Our Game: the Evolutionary Arms Race by Aizere Malibek 22 October 2024 edited by Rita Fortune illustrated by Aizere Malibek Organisms have been competing for biological domination since the beginning of life. Evolutionary adaptations arise from genetic mutations, which propel biodiversification and allow organisms with favourable traits to survive and reproduce. This is the foundation of Charles Darwin’s Theory of Evolution, explaining the rise of antimicrobial resistance and contagious viruses, while also offering solutions to these threats in public health and medicine. Mutations in the DNA of pathogens allow them to adapt to our immunological defences and invade our bodies. Conversely, the variation in our immune cells allows us to detect and defend against pathogens as a counter-adaptation. Medicine has advanced dramatically in the recent decades, with novel vaccines, antivirals and antibiotics being developed quicker than ever before. Unfortunately, persistent pathogens have found a way to survive attacks from our immune systems and drugs, making it difficult to devise an effective cure for these infections. Take HIV, for instance: the virus activates programmed cell-death in our CD4+ T immune cells and alters their metabolism as a survival mechanism (Gougeon, 2003; Palmer et al., 2016). In turn, this directly reduces the immune system’s ability to defend against the virus. This is further complicated by the high mutation rate of HIV, leading to rapid resistance to various treatment options (Gupta et al., 2018). Fortunately, scientific discoveries are helping us develop solutions for infectious diseases. It was found that HIV is susceptible to immune responses in its initial immature stages, which has become a target of the current pursuits in vaccine development for the virus (Picker et al., 2012). Vaccines are beneficial in these cases because they expose memory cells in order to inactive microbial antigens, which are a key cell involved in our active immune responses. This allows our bodies to tackle the pathogens more efficiently, reducing the symptoms and long-term effects of infection. Another emerging treatment option is through CRISPR-Cas9 technology. Originally discovered as a bacterial defence system against viruses, CRISPR allows scientists to precisely edit genes. This technology is being explored not only for its potential to correct genetic disorders, but also as a weapon against pathogens. Researchers are looking into using CRISPR to target viral DNA in infected human cells, cutting it out before the virus can replicate (Mengstie & Wondimu, 2021). If successful, CRISPR could be a game-changer in the fight against diseases like HIV, influenza, and even the next pandemic. However, HIV is just one example of this ongoing evolutionary arms race between pathogens and humans. The phenomenon isn’t restricted to just viruses; bacteria and fungi have also become significant opponents. The rise of antibiotic resistance in bacteria is an alarming and rising public health issue today. Antibiotics are increasingly losing their efficacy due to misuse and overprescription. Pathogens like Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ) have developed multiple resistance mechanisms, including the production of enzymes that break down the antibiotic molecules before they can exert their effect (Reygaert, 2018). Methicillin-resistant Staphylococcus aureus (MRSA) is a prime example of antibiotic resistance. Initially, methicillin was developed to treat penicillin-resistant strains of bacteria. However, as methicillin became widely used, new strains of S. aureus emerged that could resist the potent drug. MRSA infections are now incredibly difficult to treat and pose a serious public health threat, particularly in hospitals and healthcare settings where immunocompromised patients are most vulnerable (Collins et al., 2010). Vaccines are not as effective against bacteria and fungi due to the more complex structures of these organisms. So how do we stay ahead in this race? One promising area of research is the development of next-generation antibiotics and antivirals. Researchers are now investigating bacteriophages—viruses that specifically infect bacteria—as a potential solution to antibiotic-resistant infections. These phages, which evolve alongside bacteria, could be used to target and destroy harmful bacterial strains without the collateral damage caused by traditional antibiotics (Plumet et al., 2022). While scientific innovation is key to staying ahead in the evolutionary arms race, public health policies play an equally important role. Misuse of antibiotics, for instance, has significantly accelerated the rise of antibiotic-resistant bacteria outside healthcare settings (David & Daum, 2010). Governments and healthcare organisations are now pushing for stricter regulations on antibiotic prescriptions and promoting the responsible use of these drugs. Global collaboration is also essential. Pathogens don’t respect national borders, and the spread of infectious diseases is a global issue. Initiatives like the World Health Organisation’s Global Antimicrobial Resistance Surveillance System (GLASS) are crucial in monitoring and controlling the spread of resistant pathogens worldwide. By sharing data and resources, countries can better coordinate their responses to emerging threats, mitigating the risks posed to global health. The dynamic shifts in power between humans and pathogens continues to unfold in this evolutionary arms race. While scientific innovation is allowing the development of new tools, from vaccines to gene-editing technologies, we must also adopt policies that promote responsible drug use and global cooperation. In this race, staying at the top of our game requires constant vigilance, innovation, and adaptation—because pathogens certainly aren’t slowing down. The stakes are high, but with continued research and collaboration, we have the potential to maintain the upper hand in this ever-evolving battle for survival.

< Back to Issue 6 Cosmic Carbon Vs Artificial Intelligence by Gaurika Loomba 28 May 2024 Edited by Rita Fortune Illustrated by Semko van de Wolfshaar “There are many peculiar aspects of the laws of nature that, had they been slightly different, would have precluded the existence of life” - Paul Davies, 2003 Almost four billion years ago, there was nothing but an incredibly hot, dense speck of matter. This speck exploded, and the universe was born. Within the first hundredth of a billionth of a trillionth of a trillionth second, the universe began expanding at an astronomical rate. For the next 400 million years, the universe was made of hydrogen, helium, and a dash of lithium – until I was born. And thus began all life as you know it. So how did I, the element of life, the fuel of industries, and the constituent of important materials, originate? Stars. Those shiny, mystical dots in the night sky are giant balls of hot hydrogen and helium gas. Only in their centres are temperatures high enough to facilitate the collision of three helium-4 nuclei within a tiny fraction of a second. I am carbon-12, the element born out of this extraordinary reaction. My astronomical powers come from my atomic structure; I have six electrons, six protons, and six neutrons. The electrons form teardrop shaped clouds, spread tetrahedrally around my core, my nucleus, where the protons and neutrons reside. My petite size and my outer electrons allow my nucleus to exert a balanced force on other atoms that I bond with. This ability to make stable bonds makes me a major component of proteins, lipids, nucleic acids, and carbohydrates, the building blocks of life. The outer electrons also allow me to form chains, sheets, and blocks of matter, such as diamond, with other carbon-12 atoms. Over the years of evolution, organic matter buried in Earth formed fossil fuels, so I am also the fuel that runs the modern world. As if science wasn’t enough, my spiritual significance reiterates my importance for the existence of life. According to the Hindu philosophy, the divine symbol, ‘Aum’ is the primordial sound of the Cosmos and ‘Swastika’, its visual embodiment. ‘Alpha’ and ‘Omega’, the first and last letters of the Greek alphabet, represent the beginning and ending, that is the ‘Eternal’ according to Christian spirituality. When scientists photographed my atomic structure, spiritual leaders saw the ‘Aum’ in my three-dimensional view and the ‘Swastika’ in my two-dimensional view. Through other angles, the ‘Alpha’ and ‘Omega’ have also been visualised (Knowledge of Reality, 2001). I am the element of life, and within me is the divine consciousness. I am the beginning and I am the end. My greatness has been agreed upon by science and spirituality. In my absence, there would be no life, an idea humans call carbon chauvinism. This ideology and my greatness remained unquestioned for billions of years, until the birth of Artificial Intelligence. I shaped the course of evolution for humans to be self-conscious and intelligent life forms. With the awareness of self, I aspired for humans to connect back to the Cosmos. But now my intelligent toolmakers, aka humans, are building intelligent tools. Intelligence and self-consciousness, which took nature millions of years to generate, is losing its uniqueness. Unfortunately, if software can be intelligent, there is nothing to stop it becoming conscious in the future. Soon, the earth will be populated by silicon-based entities that can compete with my best creation. Does this possibility compromise my superiority? A lot of you may justifiably think so. The truth is that I am the beginning. Historically, visionaries foresaw asteroid attacks as the end to human life. These days, climate change, which is an imbalance of carbon in the environment, is another prospective end. Now, people believe that conscious AI will outlive humans. Suggesting that I will not be the end; that my powers and superiority will be snatched by AI. So the remaining question is, who will be the end? I could tell you the truth, but I want to see who is with me at the end. The choice is yours. References Davies, P. (2003).

< Back to Issue 2 What’s the forecast for smallholder farmers of Arabica coffee? For millions of smallholder farmers residing in the rural highlands of East Timor and Ethiopia, Arabica coffee is a major source of income. Yet, weather patterns are threatening their future livelihoods. With global coffee yields predicted to dramatically reduce in coming decades, how will this touch Melbourne’s privileged cafe culture? by Hannah Savage 10 December 2021 Edited by Ashleigh Hallinan & Irene Yonsuh Lee Illustrated by Aisyah Mohammad Sulhanuddin The world loves its coffee. After crude oil, coffee is the most exported commodity in the world and global demands are projected to skyrocket alongside demographic growth (2). With a strong inclination by Australian citizens to participate in our bourgeois cafe culture, Australian demand can be expected to mimic this trend. However, as climate change continues to throw curveballs, pressures to satisfy these demands will be felt by all in the supply chain. There are many species of coffee beans, yet global consumption relies only on a narrow genetic selection. Coffea Arabica is the dominant coffee bean species in commercial production (approximately 70 percent), followed by Coffea Robusta (2). Agricultural research and breeding of these crops are not extensive, considering their high sensitivity to climate. If Arabica was a child, it would be the no-mash-touching-the-peas type. Though a laborious crop to farm, this fussy plant has low yield when too much shade deprives it of sunlight or too little shade shrinks soil moisture levels. It insists on altitudes 1000-2000m above sea level and 2000mm of rainfall per annum (2). Moreover, the optimal air temperature for Arabica is 18-21 degrees Celsius (3). With these environmental specifications, it is expected that half of the world’s optimal areas for growth of Arabica and Robusta are expected to be lost by 2050 due to climate change (13). After Hurricane Maria hurtled across Puerto Rico in 2017, 80 percent of coffee trees were destroyed and rural livelihoods were flattened overnight (4). Climate change does not pay sympathy towards poor and marginalized rural communities. Frequency and intensity of extreme weather is increasing in many developing nations. Changes in temperature, weather events and rainfall patterns are already challenging the ability of farmers to adapt. Rainfall distribution is becoming more erratic and unpredictable. This is a key concern to farmers as rain patterns correlate with timing of flowering and fruit production (2). Flowering is usually triggered by the first rains of the wet season, yet unpredictable rains during the year may cause flowering at undesirable times. Unsynchronized ripening requires additional harvesting cycles, costing farmers more money and labour. In addition, water scarcity and warmer air temperature also have profound impacts on harvests. Prolonged drought leads to misshapen or small beans with marks and imperfections (3). Low moisture and heat stress causes wilting, death of crops or acceleration of bean growth (3). At temperatures above 23 degrees, fruit ripens too fast for a rich, sweet coffee flavour to develop (2). What will thrive from these changing climatic conditions are pests, diseases and coffee rust fungus, which are becoming more prevalent in areas previously unfavourable for their survival (5). The insect Coffee berry borer has been a particular challenge to coffee producers globally, as it feeds on coffee beans and damages plantations. One to four generations of these critters are born each fruiting season (5). Climate change brings uncertainty to the future livelihoods of millions of smallholder coffee farmers around the world, who produce 70 percent of the world’s coffee (6). While world leaders dance around pretty statistical graphs of their carbon-cutting “achievements”, there is the underlying issue that global efforts to lower emissions will not have equal consequences across geographical locations. Poorer economies abundant in fossil fuel resources are pressured to implement policies that further increase their vulnerability and are left grappling to find quick coping strategies. Although it accounts for only a small percentage of global coffee production, East Timor is one of the most economically dependent on coffee. East Timor, the small-island nation 700km north-west of Darwin, has relied on its oil sector for economic development in recent decades, but now interest from foreign traders is depleting with global trends towards renewable energy. The coffee industry has been identified by the East Timor government as being a key opportunity for sustained economic growth and reduction of rural poverty. More than 18 percent of Timorese households rely on coffee production as their primary source of income (7). Coffee producers have a poverty rate of 47.9 percent, which is higher than the national rate of poverty, 40.3 percent (7). Many coffee-producing households are without electricity or access to clean water and regular meals. Figure 1: Distribution of coffee-selling households in Timor-Leste (7). Timorese Arabica coffee farmers today celebrate achieving yields their grandparents would have considered inadequate in the early 20th century during Portuguese occupation. This reflects how much the climate has changed across generations. Rain, once predictable to begin at the end of every November, is now inconsistent and reduced (1). Unfortunately, adaptive solutions often demand high investment and low reward in the initial implementation stages. Farmers may be reluctant to remove their aging, unproductive coffee trees and replant new ones for fear of losing a major source of income while waiting for financial output from the new growth (9). There is the temptation to instead plant new crops between existing ones, which exploits soil nutrients and harms coffee yields. Small short-term rewards also discourage poorer farmers from participating in collective reforestation projects (9). There is much work to be done to restore ecosystems devastated from rainforest clearances during Indonesian colonisation in 1975, which occurred mere months after independence from Portugal. Shade trees that characterise these tropical rainforests play important roles in supporting coffee growth. If farmers grow coffee crops amongst the rainforest, crops will benefit from wind shelter and rich soil nutrients (8). Shade reduces daytime air temperature and increases humidity. In the region of Baguia, the collaboration project WithOneSeed, (co-founded by Melbourne’s own ‘The Corner Store Cafe’ owners), actively alleviates poverty by restoring rainforests and granting farmers profits from carbon credit trades. Farmers plant an indigenous shade tree, carbon credits are purchased by foreign customers to offset fossil fuel emissions and a remuneration of 50cents per tree is given to farmers each year so long as the tree survives (10). WithOneSeed therefore provides rural coffee producers with income before trees mature and re-establishes tara bandu, customary resource management that sustained Timor Leste’s environment for centuries pre-colonisation. Organic beans are purchased from smallholder farms at a fair price by The Corner Store and roasted in Oakleigh. The supply chain is transparent and traceable and profits go towards funding WithOneSeed planting. Plus the coffee is good quality and grown without nasty chemicals! (11) Simple adaptive responses are also being made by coffee producers in the world’s fifth largest Arabica producer, Ethiopia (3). As Arabica has been said to originate here, it is perhaps unsurprising that 16 percent of the population rely on coffee for their livelihood. Figure 2: The main coffee growing areas of Ethiopia (3). In the case of a global temperature rise of 2.4 degrees Celsius, land areas suitable for coffee production in Ethiopia would be expected to decline by 21 percent (12). Resilience for smallholder Arabica producers now depends on creative solutions using limited technology and resources available to rural communities. Relocating farms to higher altitudes of Ethiopian highlands is one solution. But this transition comes at a cost for coffee producers in the form of social network losses. While climate conditions of higher land might be more suitable, other factors such as land tenureship rights and soil quality may pose new obstacles (13). As rain seasons shorten and dry seasons lengthen, Ethiopian coffee producers aim to boost irrigation by diverting nearby streams. This is an ancient and cost-effective solution that enables coffee to successfully be grown in areas classified unsuitable (3). Similarly, coffee producers are carrying out traditional techniques of mulching, where laying compost over soil conserves soil moisture (3). However, more government investment in supporting these adaptations is needed to keep ahead of global warming (3). Sustainable agriculture also needs to be met with fair prices. Many Ethiopian farmers do not have access to foreign traders who will pay premium prices that outweigh production costs. Coffee prices are determined by the international market, or “C price”, which is based on the theory that cost is proportional to global demand, with no consideration of quality or organic farming practices (14). This supports and encourages cheap, unsustainable agricultural practice because sustainable or not, farmers will receive the same revenue for their produce. To combat this, Ethiopian business CoQua, based in Addis Ababa city, facilitates opportunities for private producers to link with international clients and initiate direct lines of trade (14). Through CoQua, Melbourne’s Seven Seeds cafe were able to establish a trade relationship with private smallholder Ethiopian Arabica producers. Seven Seeds claim to pay 3.56 times the “C price” (14). Continue as we may to remain disconnected from the challenges of an environmentally fragile coffee industry, it is only a matter of time before global reduction makes noticeable impacts on Melbourne’s shielded society. What will happen when coffee stocks fail to meet Melbourne demand? Seven Seeds co-owner Mark Dundon told The Sydney Morning Herald that he predicts coffee prices will rise, despite general reluctance of consumers to spill more than one bank note from their wallets for a flat white (14). And why shouldn't we pay more for our hot beverages if producers vulnerable to food insecurity are paying more from the brunt of climate change? The following decades have a bitter outlook, but the recent pandemic outbreak enhanced our ability to envision rapid global disruptions where no corner of the world is excluded. Certainly a disruption to Melbourne coffee culture is a trivial issue in the grand scheme of things, but as consumers it is one worth considering now. The future for Melbourians to satisfy their cultural addiction balances dangerously on a series of environmental conditions being met in foreign highlands. While it’s true that being a “smart consumer” can feel like a matter of blind faith (how fair is fair trade?), favouring businesses that have ethical, direct lines of trade with smallholder producers is one small, immediate solution towards building a sustainable future for our treasured beans and those in the firing line of climate change.
