概要

TLDRThe video discusses the promise of lab-grown food as a solution to critical issues like poor animal treatment and climate change. It highlights the environmental impact of traditional agriculture and the rise of cultured meat, illustrated by the first cultured beef burger introduced by Professor Mark Post. The production process is explained, focusing on the use of stem cells and bioreactors. Despite challenges such as high costs and regulatory hurdles, advocates believe lab-grown food can significantly reduce waste and adapt to nutritional requirements. The industry is projected to grow substantially by 2030.

タイムライン

  • 00:00:00 - 00:04:05

    Lab-grown food is being recognized as a potential solution to significant contemporary issues, such as animal treatment, food distribution inequality, and climate change, as agriculture contributes over a quarter of greenhouse gas emissions. High emission foods, including beef and dark chocolate, emphasize the need for alternative solutions. The viability of the cell-cultivated food industry, its processes, and consumer acceptance are examined.

ビデオQ&A

  • What is lab-grown food?

    Lab-grown food is food produced by culturing cells, typically meat from animal stem cells, in a controlled environment.

  • How is lab-grown meat produced?

    Lab-grown meat is produced by taking stem cells from animals, placing them in bioreactors with nutrient solutions, and allowing them to multiply into muscle, fat, and connective tissues.

  • What are the main challenges facing lab-grown meat?

    The main challenges include high production costs, health and safety concerns, regulatory approval, and the need for nutrient supplementation.

  • Which countries have approved lab-grown meat?

    Singapore was the first to approve lab-grown meat in 2020, followed by the U.S. in 2023, while the U.K. approved it for pet food in 2024.

  • What potential benefits does lab-grown food offer?

    Lab-grown food could reduce food waste, improve health by customizing nutritional content, and potentially create new food experiences.

  • How significant could the lab-grown meat industry become?

    According to McKinsey, lab-grown meat could represent half a percent of the global meat supply by 2030, potentially becoming a $25 billion industry.

    From the poor treatment of animals to uneven  food distribution and even climate change,
  • 00:00:05
    lab-grown food is being hailed by some as a  solution for many of today’s biggest issues.
  • 00:00:11
    Our global agriculture system is responsible for  over a quarter of all greenhouse gas emissions.
  • 00:00:16
    Among the worst offenders  are beef, dark chocolate,
  • 00:00:20
    coffee and fish, based on emissions per kilogram.
  • 00:00:24
    There has been a lot of hype  around cell-cultivated food,
  • 00:00:27
    but how viable is the industry?
  • 00:00:29
    What does it entail and, more  importantly, will consumers bite?
  • 00:00:34
    Can you do the honors and  lift the lid on your creation?
  • 00:00:37
    Over a decade ago on The Edge we reported on  the world’s first ever cultured beef burger.
  • 00:00:42
    Unveiled by Professor Mark Post from Maastricht
  • 00:00:45
    University it cost around  250,000 euros to produce.
  • 00:00:50
    On August 5th 2013, Professor  Mark Post from Maastricht
  • 00:00:50
    University unveiled the world’s  first-ever cultured beef burger.
  • 00:00:50
    At the time it cost around  250,000 euros to produce.
  • 00:00:50
    And most crucially, will consumers bite?
  • 00:00:51
    He went on to set up Mosa Meat,
  • 00:00:52
    a company which aims to bring the burger  to the masses, and he’s not alone.
  • 00:00:57
    There are now hundreds of start-ups  developing their own lab-grown products.
  • 00:01:01
    But just how do they do it?
  • 00:01:02
    It’s a relatively simple procedure, and similar  for both meat and plant-based production.
  • 00:01:07
    For meat, simply take stem cells from animals’
  • 00:01:10
    tissue and put them into bioreactors, or as  they’re more commonly known, cultivators.
  • 00:01:11
    Then add a nutrient-rich solution  and watch the cells multiply into
  • 00:01:14
    the three main components of meat:  muscle, fat and connective tissue.
  • 00:01:19
    Then put the cells into bioreactors or, as  they're more commonly known, cultivators.
  • 00:01:24
    These cells are then separated and  rearranged to build a final edible product.
  • 00:01:28
    This part of the process is called  scaffolding and can be very complicated.
  • 00:01:32
    A steak, for instance, needs a lot more  scaffolding than ground meat in a burger.
  • 00:01:37
    The entire process takes between two and  eight weeks, but the payoff can be huge.
  • 00:01:42
    It’s estimated that just 0.001 pounds of cow  cells can create up to 4.4 billion pounds of beef.
  • 00:01:50
    That sounds like an impressive  return, so what’s the hold up?
  • 00:01:53
    Well, cost is a big issue.
  • 00:01:56
    Currently, lab-grown meat is around  40% more expensive than animal meat.
  • 00:02:01
    And then there’s health and safety concerns.
  • 00:02:03
    All production must happen in a completely sterile
  • 00:02:06
    environment because the cells have  no natural immunity from diseases.
  • 00:02:10
    And while traditional meat is nutritionally dense,
  • 00:02:13
    most of its proteins, vitamins and  minerals are introduced via animal feed.
  • 00:02:18
    You have to add these nutrients  into cultured meat, and it’s still
  • 00:02:21
    unclear whether today’s additives provide  equal nutritional value in the long-term.
  • 00:02:26
    As a result, regulators can’t  seem to align on the technology.
  • 00:02:30
    Singapore became the first country in the world to
  • 00:02:32
    approve cultured meat for  human consumption in 2020.
  • 00:02:36
    The U.S. followed suit three years  later and the U.K.’s Food Standards
  • 00:02:40
    Agency approved use for pet food in early 2024.
  • 00:02:44
    Italy, meanwhile, has banned the production,  sale and import of lab-grown meat entirely,
  • 00:02:50
    with the government citing its potential negative  impact on the country’s farming industry.
  • 00:02:55
    France and Romania might do the same.
  • 00:02:57
    The EU so far has not offered any  guidance, but if it does green
  • 00:03:01
    light use, it could put Brussels on a  collision course with angry farmers.
  • 00:03:06
    Some critics are also calling for more research  into the environmental impact of cultured food,
  • 00:03:11
    especially if production  is ramped up significantly.
  • 00:03:15
    The manufacturing process, after  all, still requires an energy source,
  • 00:03:19
    but those championing the industry believe  the benefits outweigh the negatives.
  • 00:03:24
    They say cultured food has the potential  to dramatically reduce food waste,
  • 00:03:29
    tantalize our taste buds with things  we’ve never traditionally eaten
  • 00:03:33
    and could provide health benefits by  tailoring food to nutritional needs,
  • 00:03:37
    such as removing gluten or saturated  fats, without compromising on the taste.
  • 00:03:41
    According to consulting firm McKinsey, cultivated meat could make up as much as
  • 00:03:46
    half a percent of the world’s meat supply by 2030, making it a 25-billion-dollar global industry.
