Humans have been eating meat for millions of years. Archaeological evidence shows that our ancestors were consuming meat as far back as 3.4 million years ago. The nutrients from meat, especially protein and fat, played a crucial role in our evolution by providing the energy needed to develop larger brains.
In ancient times, obtaining meat meant hunting, but today, we can easily order meat products like burgers without leaving our homes. Globally, we consume over 365 million tons of meat each year, with countries like the United States and Australia leading in per capita consumption. As developing nations become wealthier, their meat consumption is expected to rise, which poses a significant environmental challenge. The meat industry is a major contributor to greenhouse gas emissions, with food production accounting for about a third of global emissions.
Many people believe we need to reduce or eliminate meat from our diets to combat climate change, but changing dietary habits can be difficult. This is where lab-grown meat comes into play. Scientists are working on creating meat in laboratories, which could allow us to enjoy meat without harming animals. This technology, though complex and controversial, is becoming more feasible.
The idea of growing meat without slaughtering animals isn’t new. In 1931, Winston Churchill envisioned a future where we could grow animal parts separately. Fast forward to 2013, when the first lab-grown burger was consumed, and now numerous startups are exploring this technology. Lab-grown meat, also known as cultured meat, uses regenerative science to grow meat from stem cells. These cells are collected from animals without causing harm and are then cultivated in a bioreactor with nutrients and growth factors to develop into muscle or fat cells.
One major challenge in producing lab-grown meat is the reliance on fetal bovine serum (FBS), which is derived from cow fetuses. FBS is essential for cell growth but contradicts the goal of creating animal-free products. It prevents stem cells from self-destructing, but finding a replacement has proven difficult. Currently, lab-grown meat production requires a significant amount of FBS, making it hard to achieve a truly slaughter-free product.
Researchers are working on synthetic or plant-based alternatives to FBS, but these solutions are still in development. Another hurdle is the cost, with current estimates suggesting lab-grown meat could cost around $10,000 per pound. Scaling up production is necessary to reduce costs, which requires substantial investment in facilities and resources.
Despite these challenges, there is optimism in the industry. The Good Food Institute has published analyses indicating that costs could decrease significantly as technology advances. Innovations in biotechnology may lead to more affordable production methods, allowing us to enjoy meat without the environmental impact of traditional farming.
Personally, I find it challenging to reduce meat in my diet, but I understand the importance of making changes for the environment. While I don’t think the responsibility for environmental change should solely fall on consumers, there’s a moral argument for reducing meat consumption. To help with this, I’ve started using the Fabulous app, which assists in building routines and habits over time. It breaks down goals into manageable steps, making it easier to incorporate healthier habits into daily life.

Engage in a structured debate with your classmates. Divide into two groups: one supporting lab-grown meat and the other advocating for traditional meat. Research and present arguments on environmental impact, ethical considerations, and economic factors. This will help you critically analyze the pros and cons of each option.
Conduct research on the use of stem cells in lab-grown meat production. Prepare a presentation that explains the science behind stem cell cultivation and its application in creating cultured meat. This activity will deepen your understanding of the technological aspects of lab-grown meat.
Work in groups to develop a business plan for a startup focused on lab-grown meat. Analyze current production costs and propose strategies to reduce them. Consider factors like scaling production and alternative growth mediums. This exercise will enhance your skills in economic analysis and strategic planning.
Conduct an environmental impact assessment comparing lab-grown meat and traditional meat production. Use data to evaluate greenhouse gas emissions, land use, and water consumption. Present your findings in a report, highlighting the potential benefits and challenges of lab-grown meat for sustainability.
Reflect on your own dietary habits and consider the role of meat consumption in your life. Participate in a workshop that uses tools like the Fabulous app to set goals for reducing meat intake. Share your experiences and strategies with peers to support each other in building sustainable habits.

Humans have been consuming meat since the beginning of our existence. Archaeologists have found marks on bones from tools that suggest we have been carnivorous for as far back as 3.4 million years ago, when our earliest hominid ancestors roamed the Earth. The protein and fat content of meat was crucial for the development of humans, as it allowed us to free up energy used in digesting plants and redirect it to building larger brains.
However, these evolutionary changes occurred during a time of hunter-gathering, where obtaining meat required hunting. Fast forward to today, and we can order a burger for delivery without leaving our homes. Globally, we consume over 365 million tons of meat each year, with countries like the US and Australia averaging around 120 kilograms per person annually. As developing countries grow wealthier, meat consumption is expected to rise, contributing to a climate crisis. The meat industry is one of the largest contributors to greenhouse gas emissions, with food production as a whole accounting for a third of all emissions globally.
Many believe it’s time to reduce or eliminate meat from our diets, but changing long-standing habits is challenging. What if there was a way to enjoy meat without harming animals? This is the goal of many scientists working on lab-grown meat, a technology that is both controversial and complex. Lab-grown meats could potentially replace the need to raise and kill animals, and this reality is becoming increasingly feasible.
The concept of growing meat without killing animals has been around for a long time. In 1931, Winston Churchill suggested that we could grow parts of animals separately. Fast forward to 2013, when the first lab-grown burger was eaten, and since then, numerous food tech startups have emerged. Lab-grown or cultured meats utilize regenerative science practices to grow meat without the need for an entire animal. The process begins with stem cells, which are harvested from the animal without causing harm. These cells are placed in a bioreactor with nutrients and growth factors to promote replication and differentiation into muscle or fat cells.
However, there is a significant challenge: the use of fetal bovine serum (FBS), which is derived from the blood of cow fetuses. This serum is crucial for the growth of lab-grown meat, but it contradicts the goal of creating animal-free products. FBS is essential because it prevents the replicating stem cells from self-destructing, but it is not easy to replace. Currently, lab-grown meat requires a substantial amount of FBS, making it difficult to achieve a truly slaughter-free product.
Efforts are underway to find synthetic or plant-based alternatives to FBS, but these solutions are still in development. The cost of lab-grown meat is another hurdle, with estimates suggesting that it could be around $10,000 per pound using current technology. Scaling up production is necessary to reduce costs, but it also requires significant investment in facilities and resources.
Despite these challenges, there is optimism in the industry. The Good Food Institute has published analyses suggesting that costs could decrease significantly in the coming years as technology advances. Innovations in biotechnology may lead to more affordable production methods, potentially allowing us to enjoy meat without the environmental impact of traditional farming.
