Nineteen thousand children [are] dying every day. Does it really matter that we're not walking past them in the street? Does it really matter that they're far away? I don't think it does make a morally relevant difference.

If you're buying animal products and can go to the farm and actually see how the animals are looked after, yes, that's an important point. That's definitely the best way of assuring yourself that the animals are being well treated.

To give preference to the life of a being simply because that being is a member of our species would put us in the same position as racists who give preference to those who are members of their race.

If we all think only of our own interests, we are headed for collective disaster - just look at what we are doing to our planet's climate.

People tend to care about dogs because they generally have more experience with dogs as companions; but other animals are as capable of suffering as dogs are. Few people feel sympathy for rats. Yet rats are intelligent animals, and there can be no doubt that rats are capable of suffering and do suffer from countless painful experiments performed on them. If the army were to stop experiments on dogs and switch to rats instead, we should not be any less concerned.

As we realize that more and more things have global impact, I think we're going to get people increasingly wanting to get away from a purely national interest.

So why don't we make ourselves the last generation on earth? If we would all agree to have ourselves sterilized then no sacrifices would be required - we could party our way into extinction!
