Nowadays, there is very little we can do about [<nowiki/>wild animal suffering]. But it is critical to start questioning the idea that we should not do anything. This is crucial so that in the future, some day, the problem can be addressed. If a community of human beings is stricken by a flood, a famine, violence, or is stricken by an epidemic, we think that if there is something we can do to help them, we should do it. Why not in the case of nonhuman animals? Normally we think that this is the way life in the wild. However, few of us who state this would be willing to let other humans die of disease, starvation or cannibalism. What is the reason for this different consideration of humans and other animals? Many reasons can be given, but all of them are merely excuses. The real motive of this dissimilar attitude is speciesism. Moreover, none of us would like to be left to die suffering in conditions such as the ones described above. In this way, if we are neither egotistical nor speciesist, and we therefore assume that we are willing to treat other animals as we would like to be treated, then we must conclude two things: not only should we care about the animals that are exploited by human beings, but we also must care about the animals that live in freedom. We must reflect on what we can do for them. This is the consequence of antispeciesism that is the most difficult to accept, and it is, in fact, a reason why many animal rights advocates are not really capable of taking a antispeciesist stance. Only those who are truly capable of leaving their most deeply rooted speciesist prejudices behind can manage to address this question. But if - as I have said above - speciesism is an unjustifiable position, we must have enough courage and responsibility to not look the other way.

The profound cultural devaluation of other animals that permits the violence that underlies the animal industrial complex is produced by far-reaching speciesist socialization. For instance, the system of primary and secondary education under the capitalist system largely indoctrinates young people into the dominant societal beliefs and values, including a great deal of procapitalist and speciesist ideology. The devalued status of other animals is deeply ingrained; animals appear in schools merely as caged “pets,” as dissection and vivisection subjects, and as lunch. On television and in movies, the unworthiness of other animals is evidenced by their virtual invisibility; when they do appear, they generally are marginalized, vilified, or objectified. Not surprisingly, these and numerous other sources of speciesism are so ideologically profound that those who raise compelling moral objections to animal oppression largely are dismissed, if not ridiculed.

Then, I claim that if we abandon a speciesist viewpoint we should change completely the way in which we should intervene in nature. Rather than intervening for environmental or anthropocentric reasons, we should do it in order to reduce the harms that nonhuman animals suffer. This conflicts significantly with some fundamental environmental ideals whose defence is not compatible with the consideration of the interests of nonhuman animals.

The animal liberation movement is fighting what is arguably the most entrenched and widespread form of exploitation in human history: speciesism.

The 1960s revolutions against racism, sexism and classism nearly missed out the animals. This worried me. Ethics and politics at the time simply overlooked the nonhumans entirely. Everyone seemed to be just preoccupied with reducing the prejudices against humans. Hadn’t they heard of Darwin? I hated racism, sexism and classism, too, but why stop there? As a hospital scientist I believed that hundreds of other species of animals suffer fear, pain and distress much as I did. Something had to be done about it. We needed to draw the parallel between the plight of the other species and our own. One day in 1970, lying in my bath at the old Sunningwell Manor, near Oxford, it suddenly came to me: SPECIESISM!

Speciesism is not suffered by species as such, b<nowiki/>ut by their individual members. There is a common confusion regarding this point. In most cases, this is probably due only to linguistic expression. But sometimes it may also be due to the fact that nonhuman animals are usually considered not as individuals but as mere live exemplifications of a species (because of widespread speciesist attitudes). Hence individuals are frequently identified with the species they belong to. But just as the group of all triangles does not have the properties that triangles themselves have, the interests of an individual cannot be said to be the interests of his or her species.

Many people think we shouldn't worry about [wild animal suffering]. Some people hold speciesist views according to which we should only care about what happens to human beings. Others hold environmentalist positions that entail that we should just care about the conservation of ecosystems or species and disregard the interests of individual nonhuman animals. According to those holding these views, nonhuman animals can be sacrificed for the sake of environmental conservation (though, interestingly, they seldom maintain this view when human beings are affected). However, if we agree that the interests of all sentient animals must be taken into account we should reject these anthropocentric and environmentalist views as speciesist.

The project of human liberation and environmental sustainability will fail without giving equal importance to anti-speciesism and animal liberation. We cannot leave intact the predatory and violent mentalities that inform our exploitative relations with animals and inform our exploitation of other humans and natural world. And to make these connections, we must all fight the Right and the rise of fascism, which has appropriated ecology for its own political purposes.

the fact that no one has come up with a really convincing reason for giving greater moral weight to members of our own species, simply because they are members of our species, strongly suggests that there is no such reason. Like racism and sexism, speciesism is wrong.

It is the responsibility of each of us—every man, woman, and child on this planet—to try to lessen the total amount of suffering in our world. … Speciesism, like racism, is a learned attitude, and both can be unlearned.

There can be no full or even adequate understanding of the systemic problems of capitalist society, of the origins and dynamics of hierarchy, and of a future rational, autonomous, ethical, and ecological society until we address the 10,000-year legacy of speciesism and the barbaric exploitation of other animals.

Let's lay it right on the line. Bigotry and racism are among the deadliest social ills plaguing the world today. But, unlike a team of costumed super-villains, they can’t be halted with a punch in the snoot, or a zap from a ray gun. The only way to destroy them is to expose them — to reveal them for the insidious evils they really are.

So what is the alternative to traditional anthropocentric ethics? Antispeciesism is not the claim that "All Animals Are Equal", or that all species are of equal value, or that a human or a pig is equivalent to a mosquito. Rather the antispeciesist claims that, other things being equal, equally strong interests should count equally. Experiences that are subjectively negative or positive in hedonic tone to the same degree must count for the same.

I’ve only known a vegan life and have been constantly teaching others of the joys and benefits of being a vegan … As an adult, I THANK my Mother profusely for being extremely honest with me as a kid and for never hiding the truth about milk, “meat”, animal experimentation … There is speciesism and that is about as cruel as it gets because it sets the stage and practice for cruelty amongst human beings. … Discrimination is discrimination—as abuse is abuse … regardless of an animals human or nonhuman form, gender, ethnicity, ability, sexual orientation or level of intelligence/knowledge it should be our birthright to LIVE our lives peacefully and harmoniously without inflicting pain on others. People who inflict intentional pain without moral or ethical regard for other human or nonhuman animals are just reminders of how much further we have to go until oppression is completely eradicated.
