Cultured Beef is created by painlessly harvesting muscle cells from a living cow. Scientists then feed and nurture the cells so they multiply to create muscle tissue, which is the main component of the meat we eat. It is biologically exactly the same as the meat tissue that comes from a cow so to all the people whom says it is not real meat, it is meat biologically or go back to school and learn basic biology.
Pros
Space
The Daily Express reports that in the UK, 85% of the total land footprint “is associated with animal products, with the land footprint of commercial lab-grown meat being 99% lower than for normal animal husbandry”.
“We can produce the same amount of meat in factories on 1% of the land it presently takes us to do it,” Prie said.
Sustainability
In America, consumers eat 26 billion pounds (13 million tons) of beef each year, which Wired says “demands a massive industrialised livestock system that is problematic for the planet”.
Worldwide, livestock “may be responsible for 15% of greenhouse gas emissions”, the magazine adds, and switching to lab-grown meat would reduce these emissions by up to 96%.
As such, it has been touted as a possible solution to global warming and climate change, and should theoretically lead to a reduction in deforestation for livestock purposes. Prie adds: “It's sustainable, environmentally friendly, we don't have to cut down rainforests to plant crops to feed animals if you're growing it in factories.”
Animal welfare
The system of farm-based meat production “rarely has the animals’ best interests in mind”, Wired says, and animal welfare in meat-producing farms and factories has long been a source of controversy worldwide.
Lab-grown meat, meanwhile, could be “environmentally and animal-welfare friendly, ethical, and less likely to carry diseases”, The Conversation suggests.
“It could increase the proportion of happy animals on Earth if it replaced intensive farm animal production. By happy, we mean well nourished, comfortable, healthy, free from pain, and able to perform.”
Health benefits
“Doing away with slaughterhouses could reduce the risk of food-borne illnesses, as well as diseases transmitted between live animals and humans,” Faunalytics says.
“In addition, lab-grown meat could easily supplemented with vitamins and minerals that are not found in natural meat and replace animal fats with healthier fats such as omega 3 or other.”
Cons
would produce greenhouses gases if it is run by coal, gas or other emitting substances but unless it is run by green energy, it will produce 94% to 97% less greenhouses gases than the coventional meat.
job losses unless the farmers covert their livestock farms into plant (fruits, veg and other) farms (jobs losses will still occur but in a lesser degree)
overall the Pros outweigh the Cons but sadly few republicans in USA are already against this as it is not "natural" or not "real meat" and somehow they think factory farming is natural :/
