I copy paste the first two from the bingo board.

First:
Yes, animals kill in the wild - to survive. We humans are, as opposed to predators, omnivores. We know how to grow crops, vegetables, etc. and cultivate fields. We have a choice, a conscience and have morals.
Are you identifying with the intelligence and life situation of that of a lion? Do you also commonly ask yourself "What would a lion do in my place right now"? Are lions that kill newborns of other lions, for example, really good role models?

I can add to this regarding your question about more intelligent animals. So because some animals choose to kill, does that justify you doing so when you know it causes suffering? That does not make sense.

Second:
There are no nutrients that stem exclusively from animals. Originally derived from bacteria and microorganisms, they are accumulated in the food chain via plants and animals. You can leave out the middleman, which is the animal. Accordingly, a balanced vegan diet can meet needs at any stage of life. For certain chronic diseases (type 2 diabetes, some cancers and heart disease), positive effects are even to be expected. Admittedly, it requires an initial conversion effort, since you have to get your nutrients via other foods and sometimes supplements. But don't worry - it's not rocket science and it's for a good cause.

Third:
I actually didn't find this one on the bingo board, so kudos. And this is sort of a grey area argument that isn't really the core of the vegan proposition. But anyway my personal opinion is that it is ethical to kill for self defense (depending on the situation), even for an animal of "higher intelligence". The same way as killing a person in self defense can be ethical in certain situations. But at the same time I don't think we have an obligation to "step in" and save animals that are subject to predation etc in the wild, see the argument under "first". This argument is quite close to the common one about killing for conservation, which is quite hillarious when you think about it. We have killed off all the natural predators, so the prey animals become overpopulated so we have to step in to kill them off for their own good.

Fourth:
Not directly on the board, but anyway. We don't need a honey bee industry for crop production. There are alternatives. And it makes more sense to use native pollinators anyways (see also here https://doi.org/10.1890/02-0626 ).

And bee farming is exploitative. We cut off the wings of the queen to force her to stay. Forcibly impregnate her, and steal the honey. See more here https://youtu.be/clMNw_VO1xo

And as for your last point, ofc we cause environmental harm, that is unavoidable. Don't let perfect be the enemy of good. Should we just give up and torture and kill sentient beings because we can't avoid causing some harm to the environment? How does that make any sense?
