Industrial livestock farming is responsible for around 15 percent of global greenhouse gas emissions. It also requires huge amounts of land and water and is thought to be contributing to the rise in antibiotic-resistant infections in humans. This is why more and more scientists and entrepreneurs are conducting research on alternatives to conventional meat production.

In California, Joshua Tetrick is working on a method of growing meat in a bioreactor. He multiplies the muscle cells of chickens in huge tanks and cultivates them with plant-based nutrients. The resulting cell pulp is molded into fibrous meat with the help of a plant scaffold. A kilo still costs many hundreds of dollars. But Joshua Tetrick hopes that production can be scaled up to a globally relevant level. After all, with ‘Good Meat’ he was one of the first two companies in the USA to receive a license for cultured meat.

At the University of California, Alison Van Eenennaam is trying to make meat production more efficient. Using the gene editing tool CRISPR she’s altered the genetic make-up of a cow so that its offspring are exclusively male. This is a great advantage, as male calves grow faster and consume fewer resources than female calves to produce the same amount of meat – thereby reducing the carbon footprint of livestock farming.

For Pasi Vainikka from ‘Solar Foods’ in Helsinki, these are all just intermediate steps on the way to a truly sustainable future food: he’s cultivating a whole new category of food in gigantic fermenters: Bacteria that are fed with CO2 and hydrogen and blended to create a product called ‘Solein’. A flavorless, protein-rich basic ingredient that can replace eggs and milk in practically all foods.

Science journalist Ingolf Baur meets some of the researchers and entrepreneurs seeking alternatives to industrial livestock farming around the world.

Sometimes it seems like a bad dream: floods, air pollution, traffic jams. Sometimes it feels like we’re surrounded by eco-monsters. But they can be defeated. YouTuber Alex Lin presents state-of-the-art devices. Arthur Zhang builds machines for upcycling plastics. And Japanese researchers are even working on mirrors in space.

DW presents: UNSEEN (Five-part documentary series)
Invisible guests in your food, your hometown sinking, unhealthy dust hiding in your lungs. Discover heroes with amazing solutions – and inspiration for a better life!

UNSEEN opens your eyes. We travel through Southeast Asia and discover stories about people whose lives could be yours. In Indonesia, children suffer from air pollution – something doctors, architects and entrepreneurs are fighting with innovative and original concepts. Then we head to Malaysia for an episode in learning how to deal with microplastics in food. We follow a fan of great cuisine on his own personal journey. What’s safe to eat and drink? Which products are good, and which don’t measure up? Next up is Thailand’s capital Bangkok, one of Asia’s sinking cities. Its inhabitants prepare for future floods, adapting their city and seeking tools to make their homes safe. In Vietnam we get caught in gridlock. Nothing new! But this time, we’re stuck with some cool rappers teaching people how not to go crazy in traffic. And finally, in Taiwan, it’s all about green tech. Learn about the hopes and limits of the new technologies being developed to solve life’s challenges. Join us on an exciting trip in five episodes – one that will open your eyes to beastly challenges and promising solutions!
