On the question of whether animal rights can be extended to plants, philosopher Tom Regan argues that animals acquire rights due to being aware, what he calls "subjects-of-a-life". He argues that this does not apply to plants, and that even if plants did have rights, abstaining from eating meat would still be moral due to the use of plants to rear animals. According to philosopher Michael Marder, the idea that plants should have rights derives from "plant subjectivity", which is distinct from human personhood. Philosopher Paul Taylor holds that all life has inherent worth and argues for respect for plants, but does not assign them rights. Christopher D. Stone, the son of investigative journalist I. F. Stone, proposed in a 1972 paper titled "Should Trees Have Standing?" that if corporations are assigned rights, so should natural objects such as trees.
Whilst not appealing directly to "rights", Matthew Hall has argued that plants should be included within the realm of human moral consideration. His "Plants as Persons: A Philosophical Botany" discusses the moral background of plants in western philosophy and contrasts this with other traditions, including indigenous cultures, which recognise plants as persons—active, intelligent beings that are appropriate recipients of respect and care. Hall backs up his call for the ethical consideration of plants with arguments based on plant neurobiology, which says that plants are autonomous, perceptive organisms capable of complex, adaptive behaviours, including the recognition of self/non-self.
In the study of plant physiology, plants are understood to have mechanisms by which they recognize environmental changes. This definition of plant perception differs from the notion that plants are capable of feeling emotions, an idea also called plant perception. The latter concept, along with plant intelligence, can be traced to 1848, when Gustav Theodor Fechner, a German experimental psychologist, suggested that plants are capable of emotions, and that one could promote healthy growth with talk, attention, and affection. The Swiss Federal Ethics Committee on Non-Human Biotechnology analyzed scientific data on plants, and concluded in 2009 that plants are entitled to a certain amount of "dignity", but "dignity of plants is not an absolute value."
When challenged by People for the Ethical Treatment of Animals to become vegetarian, Timothy McVeigh argued that "plants are alive too, they react to stimuli (including pain); have circulation systems, etc". The Animal Liberation Front argues that there is no evidence that plants can experience pain, and that to the extent they respond to stimuli, it is like a device such as a thermostat responding to sensors.
|“||Inanimate objects are sometimes parties in litigation. A ship has a legal personality, a fiction found useful for maritime purposes... So it should be as respects valleys, alpine meadows, rivers, lakes, estuaries, beaches, ridges, groves of trees, swampland, or even air that feels the destructive pressures of modern technology and modern life...The voice of the inanimate object, therefore, should not be stilled.||”|
The Swiss Constitution contains a provision requiring "account to be taken of the dignity of creation when handling animals, plants and other organisms", and the Swiss government has conducted ethical studies pertaining to how the dignity of plants is to be protected. The single-issue Party for Plants entered candidates in the 2010 parliamentary election in the Netherlands. Such concerns have been criticized as evidence that modern culture is "causing us to lose the ability to think critically and distinguish serious from frivolous ethical concerns".
In 2012 a river in New Zealand was legally declared a person with standing (via guardians) to bring legal actions to protect its interests.
