The world is facing an undeniable crisis. Climate change, biodiversity loss, water scarcity, and public health challenges are converging, and cutting across all of them is one undeniable truth: the way we produce food is no longer sustainable. Our reliance on animal agriculture isn’t just damaging the environment—it’s actively threatening the future of our planet and the people who live on it.
But here’s the exciting part: reimagining our food systems doesn’t mean a downgrade. In fact, it’s not about sacrifice at all—it’s about switching to more efficient, sustainable, and innovative ways to produce the food we love. Moving toward vegan, plant-based food systems and incorporating alternative proteins such as precision fermentation and cell-cultured meat offers a future where we can feed the world while healing the planet. Let's explore why this shift is so critical and how it benefits both people and nature.
1. Slashing Greenhouse Gas Emissions with Plant-Based Food Systems and Alternative Proteins
Animal agriculture is responsible for 14.5% of global greenhouse gas emissions, more than the entire transportation sector. This is largely due to methane, a potent greenhouse gas released by livestock, particularly cows and sheep. But it's not just about animals—how we produce protein can fundamentally change this equation.
Plant-based food systems and alternative proteins like precision fermentation (which produces animal-free dairy and meat proteins) and cell-cultured meat (which grows real meat from animal cells without the need for factory farming) can significantly reduce emissions. These systems use far less land, water, and energy than conventional livestock farming. In fact, transitioning to these innovative solutions could cut food-related emissions by up to 70% by 2050, giving us a powerful tool to combat climate change without compromising on the foods we love.
However, the urgency is real. By 2050, food-related greenhouse gas emissions could account for half of the emissions that the world could afford if global warming is to be limited to below 2°C. The longer we delay, the deeper we plunge into irreversible climate damage. Plant-based systems are not a "nice-to-have" option—they are essential if we’re going to have any hope of keeping global warming under control. Every year we continue with business as usual locks in more climate destruction, from which it will be harder and harder to recover. The time to shift is now.
2. Protecting Ecosystems, Saving Biodiversity, and Restoring Ocean Health
The current food system isn’t just warming the planet—it’s tearing apart ecosystems. Animal agriculture is responsible for around 80% of deforestation, the leading cause of habitat loss as forests are cleared to make way for livestock and crops to feed them. This leads to the destruction of habitats, threatening countless species and eroding biodiversity. The ripple effects are felt far and wide, from rainforests to grasslands. But the damage doesn’t stop on land—our oceans are also under immense pressure.
Runoff from animal farms and feed crop production has fuelled algal blooms, which create dead zones in oceans and rivers where marine life cannot survive. The impact is devastating, especially in regions like the Gulf of Mexico. Additionally, the high demand for animal protein has led to overfishing, pushing ocean ecosystems to the brink of collapse, reliant industrial methods that do not discriminate between species and endangered species, including dolphins, turtles and rays frequently caught up in nets and discarded as bycatch dead or dying.
But there’s a better way. Shifting toward plant-based systems—along with innovative solutions like alternative proteins—reduces our need for intensive land use and factory farming, allowing ecosystems to recover. This change also alleviates the strain on oceans by reducing both agricultural runoff and the reliance on overfishing. It’s about creating balance, allowing biodiversity to flourish once again.

3. Solving Food Scarcity by Producing More with Less
The way we currently produce food is highly inefficient. Meat and dairy alone consumes 83% of global farmland but delivers only 18% of the world’s calories. Feeding crops to animals and then eating those animals wastes enormous amounts of resources—land, water, and energy that could be better used to feed people directly.
By embracing plant-based food systems and alternative proteins, we can produce food far more efficiently. These systems require far less land and water, allowing us to grow more food with fewer resources. This shift is crucial in tackling food scarcity, which affects more than 828 million people globally. The world’s poorest, who are already facing the brunt of hunger and malnutrition, stand to benefit the most from a more efficient, plant-forward food system that prioritizes calories and nutrition for people—not animals.
It’s vital that we recognize how high the stakes are. With food insecurity rising and global populations growing, plant-based systems offer one of the few viable solutions for feeding billions without depleting our planet’s remaining resources. If we continue with inefficient animal agriculture, we risk pushing millions more into hunger and scarcity. This isn’t just a food issue—it’s a humanitarian crisis in the making, unless we act now.
4. Conserving Water in a Thirsty World
Water scarcity is one of the greatest threats of the 21st century, exacerbated by climate change and growing demand. And animal agriculture is one of the biggest culprits in this crisis. It takes over 1,800 gallons of water to produce just one pound of beef. In contrast, crops like lentils, beans, and grains use only a fraction of that water.
But it’s not just about plants. Alternative proteins, such as cell-cultured meat and proteins produced via precision fermentation, can further reduce water use. These technologies allow us to create high-quality protein without the massive water footprint of traditional farming, making it possible to feed more people with fewer resources.
Switching to plant-based food systems and embracing alternative proteins would significantly reduce our water consumption, ensuring that more freshwater is available for essential needs like drinking water, sanitation, and maintaining ecosystems.
5. Protecting Public Health
Our current food system isn’t just bad for the environment—it’s risky for human health too. Factory farms create ideal conditions for zoonotic diseases, which are viruses that jump from animals to humans. We've already seen the devastating consequences of this, from avian flu to swine flu and, of course, COVID-19. Moreover, the routine overuse of antibiotics in livestock farming is driving the rise of antibiotic-resistant superbugs, posing a significant public health threat.
Switching to plant-based agriculture and alternative proteins can greatly reduce the need for intensive livestock farming, cutting down on the risks of zoonotic disease outbreaks and the spread of antibiotic resistance. In addition, diets rich in plant-based foods are linked to lower rates of chronic diseases such as heart disease, type 2 diabetes, and certain cancers, leading to healthier populations.
6. Building a Sustainable and Resilient Food Future
A shift to plant-based food systems isn’t just about plants—it’s about the future of food. Technologies like precision fermentation and cell-cultured meat are revolutionizing how we produce proteins, offering foods that are familiar, delicious, and sustainable. These innovations enable us to produce meat, dairy, and other animal products without the environmental toll of traditional farming.
Moreover, plant-based systems and alternative proteins are more resilient to climate shocks. As extreme weather events like droughts and floods become more frequent, these systems offer a more reliable way to produce food with fewer resources. They’re adaptable, sustainable, and far better suited to the changing environmental conditions of our world.
Finally, these systems promote equity. By reducing the land and water demands of agriculture, we can ensure that more resources are available for people, especially in the Global South, where food and water scarcity are most acute.
Conclusion
The future of food isn’t about sacrifice—it’s about innovation. Shifting to plant-based food systems and incorporating alternative proteins like precision fermentation and cell-cultured meat will help solve many of the most urgent problems facing our planet today. From slashing emissions and protecting ecosystems to addressing food and water scarcity and improving public health, these changes are essential to building a sustainable, resilient, and equitable food future.
The best part? We can do all of this while continuing to enjoy the foods we love—just produced in smarter, more sustainable ways. The future of food is exciting, innovative, and full of possibility. And it’s one we can all be part of.
