Explain to me how a child needs something that will make him ill.
Subjectivly he needs it.
Culture is something more long-term.
How long term? There are some 5000 year old trees around and 10000 year old giant underground fungi.
A silly argument and I don't stand on it, but I thought you should know.
A culture is valuable, but if that includes causing long term suffering of other lifeforms, I don't think it's that precios. Long term does not equal fantastic.
And what is the true importance of life, particularly here on Earth?
To experience life I guess.
What will happen to the universe if Earth ceises to exist? What will happen to the universe if all life ends?
The old "if tree fell in the forest and nobody heard that - did it fall at all" argument.
Nothing important will happen, it will continue to exist, just as that fallen tree, just nobody will be there to behold it.

I think the experience is worth it, and I don't wish to take that experience away from fox, just as I don't want to take it away from myself. I like myself in all names and forms, and all is without a self. The rest is just projections created by psyche - things that don't really exist.
Do your dreams exist or someones wish to chat or that same need of the child for icecream, does law of the conservation of energy apply to it?
That all is illusion and experience is all that matters.
Of course you can go by an argument that those hunters want to experience the sight of foxes being ripped apart, true and correct.
Here my instinct of survival comes into play which says that killing a part of yourself is not a good idea. Suicidal behaviour is considered a psychic illness.
Of course that killing doesn't really destroy anything, but it limits the total ammount of the experience that universe can have of itself. One fox experience less, two, three, thousand.. etc.
