For years scientists have been developing meat in the lab using cells from living animals. It could soon provide an alternative to today's factory farming - requiring less land and being more environmentally friendly.
After years in the lab, will meats derived from animal cells finally break into the mainstream consumer market? The products could have huge implications for the planet, human health and animal welfare.
Vertical farming and lab meat are new trends in agriculture that some say could feed the rising populations of our megacities. Kerstin Schweitzer offers a first glimpse of the future at the Global Food Summit in Munich.
Humans need to eat more beans and lentils and less red meat to protect the planet and our own health, researchers said. Meat intake for adults would be limited to 14 grams per day, that's about half a slice of bacon.
Meat would actually cost about triple its current market price if we factored in its environmental impact. Could a "meat tax" cut consumption and help do what needs to be done to fight climate change?
