Like all forms of prejudice, speciesism is UGLY and HURTFUL. Despite what society teaches you, harming others for your own pleasure is always wrong. Unlearn what you've been taught. Live the Golden Rule. Be vegan.
If you can imagine such a world, then you've just imagined one where all the rest of humanity's ills have been transcended as well. The age of money, power, control, and various levels of abusive enslavement must give way to a new age.
