Leather is a hugely popular material for a range of products, but this(popular) comes at a price. The global leather industry kills over a billion animals every year. This (cause) many to ask the question: is it possible to meet the global demand of leather without (do) any harm to animals? A process called biofabrication (生物制作) may be the answer.
Biofabrication is not new; it is already commonly used in medicine. Scientists have applied the technique to grow body parts like ear, skin, and bones for transplants (移植). But it can also (use) to make other products, such as leather. Scientists will be able to make biofabricated leather with whatever qualities they want, such as extra softness, greater strength, or even different colors and patterns.
But how (exact) does biofabrication work? (grow) leather, scientists begin by taking some cells from an animal, not hurting animal in any way. They then set the cells apart and grow them in a lab. This process takes millions of cells and expands them into billions. Next, the scientists take the cells and spread them out to form thin sheets, are then put together to combine into a little (thick) sheets. Anyone can then dye and finish the leather and design it in any way they like.
Andras Forgacs supports biofabrication. He says it may even be a "natural evolution of manufacturing for mankind." We will be able to make the products we need in an efficient, responsible, creative way.
