Euthanasia
Passive euthanasia means letting a person die. A terminally ill person is allowed to die, even if treatment could help them to live longer. This includes removing life support, such as a ventilator which is being used to keep the person alive, or by not giving them food or water. Active euthanasia means doing something to end a person's life. This could be giving them an injection or pills that will cause their death.
