Animal welfare advocacy aims to improve the lives of animals by promoting their well-being, preventing cruelty, and ensuring they are treated with respect and compassion.

Climate change is a global environmental issue that affects all living beings, including animals. While it can indirectly impact animal welfare, it is not a direct animal welfare concern like factory farming, animal testing, or habitat destruction.

The "Five Freedoms" are a set of principles that outline the basic needs and rights of animals to ensure their well-being. They include freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury, and disease, freedom to express normal behavior, and freedom from fear and distress.

Animal testing is used for various purposes, including developing new drugs and treatments for human diseases, studying animal behavior and ecology, testing the safety of consumer products, and developing new agricultural practices.

Animal rights movements aim to secure the rights and interests of animals, often advocating for their liberation from human exploitation and oppression. Campaigning against fur farming, which involves the killing of animals for their fur, is an example of an animal rights movement.

Animal slaughter refers to the intentional killing of animals for food or other purposes. It is a controversial practice that raises ethical and welfare concerns, particularly when animals are subjected to inhumane conditions or unnecessary suffering.

Lethal injection is a common method of animal euthanasia, particularly for companion animals and laboratory animals. It involves the administration of a drug or combination of drugs that quickly and painlessly induce death.

The term "animal entertainment" encompasses various practices where animals are kept in captivity and used for entertainment purposes. This includes animal exhibitions, animal performances, animal tourism, and animal circuses, where animals are trained to perform tricks or engage in activities for human amusement.

Proper care and attention are essential for animal well-being and not a form of animal abuse. Animal abuse typically involves acts or omissions that cause harm, distress, or suffering to animals.

Animal breeding refers to the practice of mating animals with specific traits or characteristics to produce offspring with desired qualities. It is commonly used in agriculture, pet breeding, and research.

Enriched environments are designed to provide animals with opportunities for physical and mental stimulation, which can improve their well-being. They are not typically a concern in factory farming, where animals are often kept in cramped and barren conditions.

The term "hunting" encompasses various practices where animals are pursued and killed for sport, recreation, subsistence, or commercial purposes. Game hunting refers to hunting for sport, trophy hunting involves hunting for prized animal parts, subsistence hunting is done for food, and commercial hunting is carried out for profit.

Species-appropriate diet is essential for animal well-being in zoos. Zoos typically provide animals with diets that meet their nutritional needs and preferences.

The terms "animal experimentation," "animal testing," "animal research," and "animal studies" all refer to the practice of using animals in scientific research to investigate various aspects of biology, medicine, and other fields.

Enriched environments are not typically a concern in circuses, as they are designed to provide animals with opportunities for physical and mental stimulation. However, circuses often raise concerns about inadequate training methods, lack of veterinary care, insufficient rest and recovery time, and confinement to small cages.
