| Will you eat lab grown meat vs the actual animal meat? Lab grown meat is nothing but synthetic proteins developed using in vitro cells of animals rather than from slaughtered animals. Compared to regular meat, a cultured meat can have positive moral, health, environmental, cultural, and economic effects. It’s well known that meat is more harmful to the environment that automobiles ( Related Thread (Meat / Beef production is more harmful to the environment than cars!!)). It is estimated that 14.5% of all green house emissions come from animal meat. That figure is equivalent to all of the transportation industry on earth - trucks, buses, trains, planes, ships, cars etc. Infact, avoiding dairy and meet is the single largest way to reduce your environmental impact, not reducing plane travel and buying that electric car.

Winston Churchill foresaw the biggest food innovation of the 21st century back in 1931: "We shall escape the absurdity of growing a whole chicken in order to eat the breast or wing, by growing these parts separately under a suitable medium."
Today that prospect nears, but is still so new it doesn't have a widely agreed-upon name: cultured meat, clean meat, lab-grown meat, cultivated meat or, by its detractors, test tube meat.
All those terms denote meat grown from animal cells, rather than from a living, sentient animal. I'll call it cultured meat, but regardless of name, it may start arriving at small scale in 2022 from companies such as Mosa Meat, Memphis Meats, Aleph Farms, and Meatable. It will be positioned as a more sustainable, environmentally friendly option for meat eaters. But who it will appeal to and at what price remains a different story.
Meat production's footprint on natural resources is an accepted issue. The Food and Agriculture Organization of the United Nations says the livestock sector "is increasing pressure on ecosystems and natural resources" and "in some cases its impact on ecosystems is out of proportion with the economic significance of the sector." The FAO also estimates that 26% of the earth's land that isn't covered in ice is used for livestock grazing, and that 33% of all crop lands are used to grow crops to feed to livestock that are fed to people in a sort of nutritional bucket brigade.
Cultured meat doesn't require grazing land or tons of feed. Instead it's grown in bioreactors like those already used to produce pharmaceuticals and ethanol. A few animal cells are chosen for the type of meat desired, and placed on a biological scaffold to grow into the right shape and structure in a bioreactor that turbocharges cell growth from a speck to a serving.

The alternative meat market, on the whole, was worth US$14 billion in 2019 – just one per cent of the US$1.4 trillion global meat industry. But Barclays estimates it will grow ten times its size to US$140 billion by 2029.
Tissue culture from plant and animal cells is not in itself a new technology, and the former has been used to produce high yielding clones of economically important crops like rubber and banana.
But tremendous advances in molecular science, cell culture technology, bioreactor engineering and food science make it possible to assemble cells into tissues which resemble the meat from slaughtered animals.
Lab-grown meat further aligns closely with the “Singapore Food Story”, an initiative by the Government to strengthen the country’s food security. One of its major thrusts is to encourage innovation in alternative proteins at home.
With limited land and water resources, Singapore’s potential to improve its food self-sufficiency is to rely on technology-enabled farming and culturing meat in bioreactors.
Both are akin to growing food in traditional agriculture systems, albeit using less space and capitalising on the country’s high technological capabilities.
These reasons have provided the impetus for Singapore to move its agriculture into controlled environments, such as vertical vegetable farms. | Source Quote:
When it comes to making realistic lab-grown meat, one of the hardest things to replicate is not the taste, but the feel. In a new study, researchers created a spongy 3D scaffold out of soy protein that both scientists and tasters say made a clump of bovine cells feel like the real deal, Inside Science reports. Scientists have been able to grow “nuggets” of muscle cells to use for hamburgers and meatballs (above). But for this new study, they wanted to create something that felt more like a steak. So they seeded and grew three cell types—smooth muscle, endothelial cells, and satellite cells—a combination that gave the end product more meatlike texture properties than the scaffold alone, the researchers write in Nature Food. When three volunteers tasted the “steak,” they reported a good taste, aroma, and, most importantly, texture. The researchers say their new scaffold could help scale up the production of different types of cultured meats—and provide protein sources beyond animal agriculture. | Source Quote:
Scientists at the University of Bath have grown animal cells on blades of grass, in a step towards cultured meat.
If the process can be reproduced on an industrial scale, meat lovers might one day be tucking into a slaughter-free supply of "bacon".
The researchers say the UK can move the field forward through its expertise in medicine and engineering.
Lab-based meat products are not yet on sale, though a US company, Just, has said its chicken nuggets, grown from cells taken from the feather of chicken that is still alive, will soon be in a few restaurants.
Chemical engineer Dr Marianne Ellis, of the University of Bath, sees cultured meat as "an alternative protein source to feed the world". Cultured pig cells are being grown in her laboratory, which could one day lead to bacon raised entirely off the hoof. | Source Quote:
There's increasing concern about the impact of meat consumption on the planet. Around a quarter of the greenhouse gas emissions that are driving up temperatures are estimated to have come from agriculture.
Beef production is considered the worst offender with cattle emitting methane and nitrous oxide from their manures, but also from their digestive processes.
There are also additional gases from fertiliser application to land, from the conversion of land for pasture or feed production.
Because of these impacts on the climate and because of a range of other concerns about issues such as welfare and sustainability, scientists have in recent years sought to develop meat that can be grown from animal cells in factories or laboratories. | Source
