1
From the poor treatment of animals to uneven food distribution and even climate change,
2
lab-grown food is being hailed by some as a solution for many of today's biggest issues.
3
Our global agricultural system is responsible for over a quarter of all greenhouse gas emissions.
4
Among the worst offenders are beef, dark chocolate, coffee and fish based on emissions per kilogram.
5
There has been a lot of hype around cell-cultivated food, but how viable is the industry?
6
What does it entail and more importantly, will consumers bite?
7
Can you do the honours and lift the lid on your creation?
8
Over a decade ago on the Edge, we reported on the world's first ever cultured beef burger.
9
Unveiled by Professor Mark Post from Maastricht University, it cost around €250,000 to produce.
10
He went on to set up MoSoMeat, a company which aims to bring the burger to the masses, and he's not alone.
11
There are now hundreds of startups developing their own lab-grown products, but just how do they do it?
12
It's a relatively simple procedure and similar for both meat and plant-based production.
13
For meat, simply take stem cells from animal's tissue, add a nutrient-rich solution and watch the cells multiply into the three main components of meat,
14
muscle, fat and connective tissue.
15
Then put the cells into bioreactors or as they're more commonly known, cultivators.
16
The cells are then separated and rearranged to build a final edible product.
17
This part of the process is called scaffolding and can be very complicated.
18
A steak for instance needs a lot more scaffolding than ground meat in a burger.
19
The entire process takes between two and eight weeks but the payoff can be huge.
20
It's estimated that just one thousandth of a pound of cow cells can create up to 4.4 billion pounds of beef.
21
That sounds like an impressive return.
22
So what's the hold up?
23
Well, cost is a big issue.
24
Currently, lab-grown meat is around 40% more expensive than animal meat.
25
And then there's health and safety concerns.
26
All production must happen in a completely sterile environment because the cells have no natural immunity from diseases.
27
And while traditional meat is nutritionally dense, most of its proteins, vitamins and minerals are introduced via animal feed.
28
You have to add these nutrients into cultured meat
29
and it's still unclear whether today's additives provide equal nutritional value in the long term.
30
As a result, regulators can't seem to align on the technology.
31
Singapore became the first country in the world to approve cultured meat for human consumption in 2020.
32
The US followed suit three years later, and the UK's Food Standards Agency approved use for pet food in early 2024.
33
Italy, meanwhile, has banned the production, sale and import of lab-grown meat entirely,
34
with the government citing its potential negative impact on the country's farming industry.
35
France and Romania might do the same.
36
The EU so far has not offered any guidance, but if it does green light use, it could put Brussels on a collision course with angry farmers.
37
Some critics are calling for more research into the environmental impacts of cultured food, especially if production is ramped up significantly.
38
After all, the manufacturing process still requires an energy source, but those championing the industry believe the benefits outweigh the negatives.
39
They say cultured food has the potential to dramatically reduce food waste, tantalise our taste buds with things we've never traditionally eaten,
40
and could provide health benefits by tailoring food to nutritional needs such as removing gluten
41
or saturated fats without compromising on the taste.
42
According to consulting firm McKinsey, cultivated meat could make up as much as half a percent of the world's meat supply by 2030,
43
making it a $25 billion global industry.

Was du lernst

Dieses Video hilft dir, Englisch sprechen zu üben, indem du komplexe Themen wie nachwachsende Lebensmittel klar ausdrückst. Du trainierst, lange Sätze flüssig zu folgen, und lernst, Argumente zu strukturieren – perfekt für Diskussionen. Außerdem verbessert es dein Verständnis von Fachbegriffen wie "bioreactors" oder "scaffolding", die in aktuellen Debatten vorkommen.

Horch auf diese Klänge

Achte auf Verbindungen im gesprochenen Englisch: Zum Beispiel "it cost around" wird oft zu "it cost 'round" reduziert, oder "and watch the cells" wird zu "an' watch the cells" verkürzt. Auch "nutrient-rich solution" hat eine flüssige Überleitung zwischen "nutrient" und "rich", wobei das "t" fast verschwindet. Diese Reduktionen machen das Sprechen natürlicher – und du kannst sie mit Englisch Shadowing üben!

Spreche wie ein Native

Um den Rhythmus des Speakers zu kopieren, betone Schlüsselwörter wie "250.000 Euro", "4,4 Milliarden Pfund" oder "25-Milliarden-Dollar-Industrie". Diese Zahlen tragen die Bedeutung und werden deutlicher gesprochen. Achte auch auf die Intonation in Fragen wie "What does it entail and, more importantly, will consumers bite?" – die Stimme steigt bei "entail" und fällt bei "bite", um die Aufmerksamkeit zu lenken. Nutze eine shadowing site, um direkt hinter dem Speaker zu sprechen: Wiederhole Sätze sofort nach ihm, um Rhythmus und Betonung zu internalisieren. Mit "shadow speech" oder "shadowspeaks" trainierst du nicht nur das Hören, sondern auch das Sprechen – und siehst schnell Fortschritte!

Grammatik in diesem Video

Die Strukturen, die der Sprecher am häufigsten verwendet, mit den genauen Worten aus dem Video:

Passiv be + Partizip Perfekt – wichtig ist, was geschieht, nicht wer es tutbeing hailed · are then separated · is called
Present Perfect have/has + Partizip Perfekt – eine vergangene Handlung, die jetzt noch wichtig isthas been · has banned · has not offered

Was ist die Shadowing-Technik?

Shadowing ist eine wissenschaftlich fundierte Sprachlerntechnik, die ursprünglich für die professionelle Dolmetscherausbildung entwickelt und durch den Polyglotten Dr. Alexander Arguelles populär gemacht wurde. Die Methode ist einfach aber wirkungsvoll: Du hörst englisches Audio von Muttersprachlern und wiederholst es sofort laut — wie ein Schatten, der dem Sprecher mit nur 1–2 Sekunden Verzögerung folgt. Anders als passives Hören oder Grammatikübungen zwingt Shadowing dein Gehirn und deine Mundmuskulatur, gleichzeitig echte Sprachmuster zu verarbeiten und zu reproduzieren. Studien zeigen, dass es Aussprachegenauigkeit, Intonation, Rhythmus, verbundene Sprache, Hörverständnis und Sprechflüssigkeit signifikant verbessert — was es zu einer der effektivsten Methoden für die IELTS Speaking-Vorbereitung und reale englische Kommunikation macht.
