I'm just watching the film "the end of meat" theendofmeat.com/en/watch.html which has just been released. I'm watching it on amazon amazon.co.uk/gp/video/detai... , but sure it is streaming elsewhere. It's a German film. One of its themes is the intelligence of pigs, featuring estherthewonderpig.com which is a huge pet pig. However a big thrust of the film is how the big meat companies have seen the writing on the wall and so are going plant based, with nothing of them wanting to be left behind.
It is not just the big companies but also how artisan butchers etc are seeing vegan foods as where they will grow. This means lots of new dairy free cheeses coming on stream.
The film talks about the drive for this being the bad press the meat industry is getting for the planet's climate. It echoes the point that the meat industry causes more climate issue than all transport including aeroplane flights.
Relevant to health the film reports the Oxford University study that if people went vegan the saving of health costs could be 1.3 trillion, but the film is not clear whether this is a global figure or what.
Another thread is the destruction of animal biodiversity, with much of this being caused by animal farming. It highlights how 70% of amazon rainforest destruction is caused by animal farming. It argues if the world went vegan then an area the size of the amazon rainforest could be reforested today and still provide enough food to feed the planet.
The film talks particularly about india which has around 30% vegetarian population and is heading to be the most populous country in the world. It talks about India being one of the biggest meat exporters.
The jainist religion advocates in gudjurat seem to have even offered their bodies to be killed and eaten instead of animals. For anyone who doesn't know, jainists are reported to wipe the ground in front of them as they walk so they don't kill insects etc.
The film finishes with the launch of cultured meat an cutured dulse, which apparently tastes like bacon and according to the film's them could produce enough protien to feed the world. (I'll have to look into cultured dulse more, since this is the first time I have come across the idea.) The point is made that cultured meat is aimed at meat eaters who don't want to become vegans. It says that if by and large vegans adopted this cutured meat that would be a bad outcome.
There is very little focus if any in the film on slaughterhouse killing of animals. For anyone who has watched the BBC film Carnage I guess it takes a similar closing position, that in the future we will look back and think of eating animals as a bad thing.
