Food-tech's here to feed the world without devouring it

Picture this: 295 million people face severe hunger right now. Meanwhile, traditional farming consumes 70% of global freshwater, emits 11 billion tonnes of carbon dioxide annually and is responsible for 90% of deforestation worldwide.

Every year, we lose about 12 million hectares, roughly the size of Greece, to drought and erosion. With an expected 10 billion mouths to feed by 2050, the current food supply trajectory simply isn't sustainable.

But there is hope. Technology breakthroughs in food production are now a science fiction writer's envy. Remember 2013's $330,000 lab-grown burger? Today, cultivated meat pioneers like Upside Foods have slashed costs to about $20 (under lab conditions), a staggering reduction. Singapore became the first country to approve cultivated chicken commercially in 2020, followed by the US in 2023. Yet, production remains minuscule. Eat Just's pilot facility currently produces only about 3kg of lab-grown chicken per week, compared to 4,000-5,000kg at a regular shop. Although meaningful scale is years away, cultivated meat's environmental potential is compelling: studies on beef show it could cut emissions and land use by up to 90% and reduce water use by around 80% compared to conventional beef (in a best-case scenario, assuming the use of renewable energy).
