Five Attributes of Persons
1) Consciousness
2) The ability to reason
3) Self-motivated activity
4) Capacity for communication
5) Self-awareness
Person ≠Human: Note that not all humans are persons (e.g., the severely mentally disabled), and not all persons are humans (e.g., intelligent aliens).
No single criterion above is necessary or sufficient to be a person. Combinations of 3 or 4 of these 5 traits might be sufficient in order to count as a person. The more of these 5 features something has, the stronger that thing's right to life is.
Plants are not persons.
People do not think that a child is morally repugnant for plucking blades of grass from the ground, or that a teenager is morally repugnant for mowing the lawn during the summer to earn money.
People possess this intuition because plants are not persons. Killing plants is not morally analogous to killing pigs or dogs.
Ummm, Peter Singer argues that even infants as old as a year or so are not self-aware and therefore that they may be killed. And some disabled people. And... Here's an excerpt from the entry for Peter Singer at Wikipedia:
_________________________
Similar to his argument for abortion, Singer argues that newborns lack the essential characteristics of personhood—"rationality, autonomy, and self-consciousness"[20]—and therefore "killing a newborn baby is never equivalent to killing a person, that is, a being who wants to go on living."[21]
Singer classifies euthanasia as voluntary, involuntary, or non-voluntary. Voluntary euthanasia is that to which the subject consents. He argues in favour of voluntary euthanasia and some forms of non-voluntary euthanasia, including infanticide in certain instances, but opposes involuntary euthanasia.
Religious critics have argued that Singer's ethic ignores and undermines the traditional notion of the sanctity of life. Singer agrees and believes the notion of the sanctity of life ought to be discarded as outdated, unscientific, and irrelevant to understanding problems in contemporary bioethics. Bioethicists associated with the Disability Rights and Disability Studies communities have argued that his epistemology is based on ableist conceptions of disability.[22]
Singer has experienced the complexities of some of these questions in his own life. His mother had Alzheimer's disease. He said, "I think this has made me see how the issues of someone with these kinds of problems are really very difficult".[23] In an interview with Ronald Bailey, published in December 2000, he explained that his sister shares the responsibility of making decisions about his mother. He did say that, if he were solely responsible, his mother might not continue to live.[24]

I myself think that Singer is more disabled than those he says we should be allowed to kill: they are not much of a threat to me, but Singer is.
