Animals are feeling sentient beings, there is worse effect to environments and the world with animal agriculture and there is much more water, land and resources used, and it isn’t even better for our health. So we in our modern society do not need any of the things from animals. There is no good reason for people to not know about this, so all this should be communicated. People decide what to do themselves, and hopefully they will the right way.
I wouldn’t even guess at the statistics of nutritional education, but I would believe you that most people don’t know about algae oil. What I’m saying is that there exist a significant number of people who do know about the inherent cruelty of factory farming, and the availability of cruelty-free alternatives, and they still won’t change their habits or consumption. It’s not a big secret anymore, and the internet exists to provide all information to anyone who wants it.
It’s like assuming Americans use the imperial measurements because they don’t know about metric. Sure, many Americans don’t know the metric system, but just learning it exists and understanding the advantages doesn’t compel Americans to switch.
Going vegan is a disruption. At a minimum, it means changing the groceries you buy. It means reading ingredients and scanning menus at all your favorite restaurants. It means depriving yourself of some previous enjoyment.
There are many people who don’t know the extent of cruelty. There are many people who are unaware of their options. And there are many people who, upon learning these things, immediately change their consumption behaviors because the thought of enjoying food or products that come from suffering is abhorrent. For OP, just knowing that suffering is not required for survival is enough motivation to stop consuming animal products. My point is that it is a mistake to assume that the same knowledge would move the needle for most people.
I said I don’t want to guess at statistics, but let’s do a thought experiment. Imagine you went to a barbeque and told everyone standing around that you had a video showing how the animals people are eating are treated. How do you suppose people would react to you offering to show them that video? How many would watch it? How many would react with anger and disgust because they already know what’s in the video? How many of them would trade their burger for a veggie patty?
My point is, it’s not that they don’t know. People know. People don’t want to think about it. And yes, share the info and maybe a few more people stop eating meat. I’m not suggesting that you or OP shouldn’t share information. All I’m saying is that if you expect it to be enough, you’re setting yourself up for a lot of disappointment.
