    Yep for those curious how it harms native bees:

    But scientists say competition with honey bees may also play a role. In a 2017 report in Conservation Letters, researchers calculated that during three months, honey bees in a typical 40-hive apiary collect the equivalent amount of pollen and nectar as 4 million solitary wild bees. “Brilliant foragers,” honey bees can “dominate floral resources and suppress native bee numbers,” says lead author Jim Cane, a retired federal biologist who heads the nonprofit WildBeecology.

    Honey bees also carry diseases that can infect natives, including deformed wing virus and the parasite Crithidia bombi. Researchers have found that native bees near apiaries can suffer a high incidence of such illnesses.

    Also some fun facts: most North American native bee species don't even live in hives or produce honey for themselves at all. They also almost never sting too

    Unlike honey bees, more than 90 percent of our nearly 4,000 native bee species live not with other bees in hives but alone in nests carved into soil, wood or hollow plant stems. Often mistaken for flies, the majority are tiny and do not have queens or produce honey. Without a hive’s larvae and food supplies to defend, “native bees almost never sting,” Mizejewski say

  • Quite a range of things. It's so many It's hard to list them all. Some of these are more global than others:

    Eyestalk ablation is the removal of one (unilateral) or both (bilateral) eyestalks from a crustacean. It is routinely practiced on female shrimps (or female prawns) in almost every marine shrimp maturation or reproduction facility in the world, both research and commercial.

    https://en.wikipedia.org/wiki/Eyestalk_ablation

    Chick culling or unwanted chick killing is the process of separating and killing unwanted (male and unhealthy female) chicks for which the intensive animal farming industry has no use. It occurs in all industrialised egg production, whether free range, organic, or battery cage.

    https://en.wikipedia.org/wiki/Chick_culling

    A gestation crate, also known as a sow stall, is a metal enclosure in which a farmed sow used for breeding may be kept during pregnancy.[1][2][3] A standard crate measures 6.6 ft x 2.0 ft (2 m x 60 cm).[4][5]

    [...]

    There were 5.36 million breeding sows in the United States as of 2016, out of a total of 50.1 million pigs.[8] Most pregnant sows in the US are kept in gestation crates.

    Ventilation shutdown (VSD) is a means to kill livestock by suffocation and heat stroke in which airways to the building in which the livestock are kept are cut off. It is used for mass killing — usually to prevent the spread of diseases such as avian influenza. Animal rights organizations have called the practice unethical.

    From global estimates

    It’s estimated that three-quarters – 74% – of land livestock are factory-farmed

    [...]

    Combine land animals and fish, and the final estimate comes to 94% of livestock living on factory farms.

  • The method of mass killing are quite brutal too. In the last outbreaks, primarily these were the two primary methods:

    Ventilation shutdown (VSD) is a means to kill livestock by suffocation and heat stroke in which airways to the building in which the livestock are kept are cut off. It is used for mass killing — usually to prevent the spread of diseases such as avian influenza. Animal rights organizations have called the practice unethical. The addition of carbon dioxide or additional heat to the enclosure is known as ventilation shutdown plus (VSD+).[1][2][3][4][5]

    Foam depopulation or foaming is a means of mass killing farm animals by spraying foam over a large area to obstruct breathing and ultimately cause suffocation.[1] It is usually used to attempt to stop disease spread.[2] Foaming has also been used to kill farm animals after backlogs in slaughtering occurred during the COVID-19 pandemic.[3] Foam depopulation has been used on poultry and pigs and has seen initial research for use on cattle.[4] It has faced criticism from some groups. Some veterinarians have called it inhumane,[5] along with many animal rights and animal welfare organizations who cite the pain caused by suffocation or the harm experienced by the stray survivors.[6][7]

  • The science doesn't agree with that

    It is the position of the Academy of Nutrition and Dietetics that appropriately planned vegetarian, including vegan, diets are healthful, nutritionally adequate, and may provide health benefits for the prevention and treatment of certain diseases. These diets are appropriate for all stages of the life cycle, including pregnancy, lactation, infancy, childhood, adolescence, older adulthood, and for athletes. Plant-based diets are more environmentally sustainable than diets rich in animal products because they use fewer natural resources and are associated with much less environmental damage. Vegetarians and vegans are at reduced risk of certain health conditions, including ischemic heart disease, type 2 diabetes, hypertension, certain types of cancer, and obesity. Low intake of saturated fat and high intakes of vegetables, fruits, whole grains, legumes, soy products, nuts, and seeds (all rich in fiber and phytochemicals) are characteristics of vegetarian and vegan diets that produce lower total and low-density lipoprotein cholesterol levels and better serum glucose control. These factors contribute to reduction of chronic disease

    https://pubmed.ncbi.nlm.nih.gov/27886704/

    Nevertheless, several RCTs [randomized controlled trials] have examined the effect of vegetarian diets on intermediate risk factors of cardiovascular diseases (Table 1). In a meta-analysis of RCTs, Wang et al. (22) found vegetarian diets to significantly lower blood concentrations of total, LDL, HDL, and non-HDL cholesterol relative to a range of omnivorous control diets. Other meta-analyses have found vegetarian diets to lower blood pressure, enhance weight loss, and improve glycemic control to greater extent than omnivorous comparison diets (23-25). Taken together, the beneficial effects of such diets on established proximal determinants of cardiovascular diseases found in RCTs, and their inverse associations with hard cardiovascular endpoints found in prospective cohort studies provide strong support for the adoption of healthful plant-based diets for cardiovascular disease prevention

    Well-planned vegan and other types of vegetarian diets are appropriate for all stages of the life cycle, including during pregnancy, lactation, infancy, childhood, and adolescence. Vegetarian diets offer a number of nutritional benefits, including lower levels of saturated fat, cholesterol, and animal protein as well as higher levels of carbohydrates, fiber, magnesium, potassium, folate, and antioxidants such as vitamins C and E and phytochemicals

  • Feed additives don't change overall methane emissions much, and not at all near what's touted by grossly misleading stats

    What’s more, feeding cattle algae is really only practical where it’s least needed: on feedlots. This is where most cattle are crowded in the final months of their 1.5- to 2-year lives to rapidly put on weight before slaughter. There, algae feed additives can be churned into the cows’ grain and soy feed. But on feedlots, cattle already belch less methane—only 11 percent of their lifetime output

    [...]

    Unfortunately, adding the algae to diets on the pasture, where it’s most needed, isn’t a feasible option either. Out on grazing lands, it’s difficult to get cows to eat additives because they don’t like the taste of red algae unless it’s diluted into feed. And even if we did find ways to sneak algae in somehow, there’s a good chance their gut microbes would adapt and adjust, bringing their belches’ methane right back to high levels.

    [...] All told, if we accept the most promising claims of the algae boosters, we’re talking about an 80 percent reduction of methane among only 11 percent of all burps—roughly an 8.8 percent reduction total
