I think it is funny to make this an ethics discussion when there is plenty of evidence that bacon and sausage cause digestive tract cancers. Meat is also pretty expensive unless heavily subsidized.
I think the main focus should be on educating people that a healthy diet contains a very small amount of meat even though the meat industry has managed to make people think it should be in every meal.
While researching another issue, I found some evidence that a vegan diet can be better than the average meat diet. This could be because the meat in pet food is of poor quality and is more likely to be spoiled than plants.
You could of course grow mice or purchase expensive meats but once it is well-rearched, a vegan diet may be a more economical way to provide a good nutrient profile.
Does it matter? A discussion is not about signalling that you support the correct side even though social media seems to think so.
Growing it in a lab is likely worse that growing it in an animal. Synthetic imitations are the only efficient replacement.
I calculated at one point that if you ride a bike instead of a car but replenish the calories with pure beef, it is better to ride the car. So diet matters.
Of course there is a limit. The question is how high it is. For instance, at high enough CO2 concentrations, the greenhouse effect doesn’t get much stronger anymore. Also, the more CO2, the faster it dissapears by eroding rocks. That happens on a geological timescale, though.
If we did something to lower temperature, I’d be very worried about the CO2 concentration’s other effect: feeling like suffocating all the time.
You can patch bugs but a buggy game will never be like Factorio. Also, fanmade fixes tend to introduce some wonkyness.
it is better than the competition but it will never be like Google before 2019 because they’ll never build their own index.
