Leather and meat without killing animals | Andras Forgacs

The Future of Biofabrication: Growing Leather Without Animals

Introduction to Biofabrication

• The speaker discusses the initial skepticism faced when starting a company focused on 3D printing human tissues and organs, highlighting significant advancements made since then.

• Questions arose about the potential to grow animal products like meat and leather, leading to a realization that current practices in animal agriculture may be viewed as wasteful in the future.

Environmental Impact of Animal Agriculture

• The global herd of 60 billion animals is maintained for food production, which will need to nearly double as the population grows to 10 billion.

• Livestock contributes significantly to land use, water consumption, and greenhouse gas emissions, posing risks to public health and food security.

Concept of Biofabrication

• Biofabrication involves using cells—the basic unit of life—to grow biological products instead of raising complex animals for simple tissues.

• The speaker emphasizes leather as an ideal starting point for biofabrication due to its widespread use and simpler technical requirements compared to other animal products.

Process of Growing Leather

• To create cultured leather, cells are taken from an animal through a harmless biopsy process. This allows the source animal (e.g., cow or lamb) to live without harm.

• Skin cells are multiplied in culture until they produce collagen, which forms the extracellular matrix essential for leather.

Characteristics and Advantages of Cultured Leather

• The first batch of cultured leather is presented as genuine leather produced without animal sacrifice; it can be shaped into various products without waste.

• Cultured leather offers fine control over properties such as thickness and texture, allowing customization beyond what conventional leather can provide.

Vision for Future Production Facilities

• The speaker envisions facilities where cultured materials like leather or meat could be produced cleanly and transparently, contrasting with traditional factories' hidden processes.

The Evolution of Manufacturing

A New Paradigm in Manufacturing

• The speaker discusses the evolution of manufacturing as a natural progression for humanity, emphasizing its environmentally responsible and efficient nature.

• Highlights the humane aspect of modern manufacturing, suggesting it allows for greater creativity in designing new materials and products.

• Advocates for moving beyond traditional practices that involve killing animals as resources, promoting a more civilized approach to production.
