Because animals have rights, it is unethical to exploit them and kill them for our own pleasure or economic benefit (George, 1994). Its assumed that cars produce most if not all the greenhouse gas emissions however livestock has a big say in air pollution. INTRODUCTION Just because cognitive abilities of animals are not as developed as those of humans, it does not suggest that they are incapable of feeling pleasure or pain and it doesn’t give humans any reason to inflict pain upon them. It will then go on to discuss the way the international community should address global food security while reducing the animal agriculture industries effect on the environment. However, the environmental impacts are deleterious. Deep muscle myopathy, fluid accumulation and skeletal disorders associated with accelerated muscle growth and restricted movement can be seen quite commonly in facilities where animals are mass produced for meat (Smil, 2002).
