This being a forum of mostly tech workers, many of us can afford to choose more sustainable animal products and support agriculture that promotes biodiversity and carbon sequestration too. If you don't want to give animal products up, then look for sources that engage in regenerative agriculture practices. They tend to be the most humane ways to raise animals as well.
In the end, demand for meat, eggs, and dairy is never going to disappear. Maybe someday lab grown alternatives can be molecularly and structurally equivalent. But until then the most effective change we can make collectively is to change government incentives to farmers so they choose better practices.
There are also environmentally beneficial meats. So much so that when rewilding we sometimes need to add the same animals back (as is happening in Scotland - rewilders are breeding cattle that look like wild ones to make it "natural"). In the UK you can buy venison from wild animals that need to be culled to to preserve the environment.
The problem is systemic and blaming other people for their lifestyle choices is neither effective nor helpful and just leads to further division. It's exactly this sort of division that helps fossil companies to destroy the planet and keep making money.

More than 70% of CO2 from energy, less than 6% from ALL livestock.
I do want to mention that you do also have to look out to get enough of : Omega 3, Calcium, Iodine, Iron, Selenium, Protein.
Takes a bit of work at the start to adapt but it's very doable, and it's not like Omnivores don't have comparable deficiencies from not eating enough plants and fruit. Not to mention other problems that come with eating animal products...
I only supplement with Omega 3, Vitamin D, B12, Iodine (although sometimes I go for wakame). Have been on a plant-based diet for around 4 years now, feeling healthy.
Global meat production is only increasing.
You're delusional with main character syndrome?
You do realize those soybean plantations are not for human consumption, right? And that that's what is factored into the quoted loss of biodiversity?
And if you're not willing to do your part, that just means the rest of us have to pull double duty.
