A few hundred years back, Scientists with revolutionary ideas and other so called 'heretics' were routinely burnt at the stake by the Church - today we are horrified by the very thought of it and it’s unbelievable that something like that can be even remotely possible in this day and age. In another 50 to 100 years, we would be similarly horrified at the thought that there was a time when animals were slaughtered for meat.
In keeping with the exponential times that we are living in, lab grown meat is starting to go mainstream a lot faster than expected. Fair guess that within 10 years most countries will have a a fake meat burger on the menu in Burger King, McDonald and even restaurants and smaller fast food joints. Probably ( hopefully ! ) in 20 or 30 years, there won’t be any animals killed for meat anymore. Apart from saving untold misery to the animals, artificial meat will cut down on one of the biggest pollution sources. Rearing, transporting and processing ( cows and pigs especially ) animals is a huge contributor to pollution. In thousands of cattle-for-meat rearing farms, methane present in cow flatulence alone is a big part of what burns a hole in the ozone layer.
Not to mention that eating meat will become a whole lot more ethical and many vegans will turn 'non-vegetarians’ — people who would otherwise like meat but don’t eat it because of the animal suffering involved. From an economic POV, this will expand the non-veg market itself. No wonder then that of the two most promising startups in the fake meat industry - Beyond Meat is having insane valuations on NASDAQ and investors are eagerly waiting for Impossible Foods to go public.
Interesting times ahead !
