Animals should not be kept in captivity

Ok So what my opponent does not understand is that my argument is in no way debating the fact that animals are treated well, I base my argument on the fact of the greater good. The fact that animals being kept in captivity are being treated horribly is not the case of the question posed, the big argument I pose to you is the fact that it is necessary Animals must be kept in captivity for necessary medical research, various studies conducted, and yes, even for the enjoyment of our children. If a Tiger in the wild attacks a baby elephant, rips it from its herd, kills it, and then eats on its inside, Is this a tragedy? That tiger doesn't need to kill that animal to survive, it is not it base instinct to kill that animal, it hunts the prey due to the natural order, in the same way that Humans, kill, hunt, capture and eat animals for the natural order. "First of all animals are used for medicine when kept in captivity but like I said people kill these captive animals for medicine killing animals and selling them and using their fur for medicine. If they want to use it for medicine why don't they use some kind of machine they could invent to help make medicine out of animals without killing them and plants could be used as medicine for healing so that's no excuse to say that they need to keep animals captive to kill and produce medicine" On this idea, do we have such a machine? can you show me some way in which we can create vaccines without killing the animals? The time to fight the diseases is only in the present. should we wait for 20 years for these machines to be thought up, created, tested when we have a vaccine ready to use, right here right now. This is natural, the death of animals to further the research of man "To clear all of that away animals should be not kept in captivity because it keeps them away from there true home. Humans should not kill so many innocent animals for money or others. Animals do not like it when they are captive and abused." Animals do not like it? where is that source from? where is the proof in that? did you ask them yourself? It is all necessary to kill animals, even for money, humans are the top of the pecking order and we have a right to kill. These sanctuaries are doing a really good job of taking care of animals and keeping them in the wild where there true home is not being imprisoned. With these sanctuaries animals are able to roam around whenever they please and sanctuaries breed, feed and take care of animals unlike zoos which how they just kill,trade,train them to entertain public, and prison animals. In this decision I would rather live in a sanctuaries then a zoo. living in a sanctuary is still living in captivity, you can not argue against captivity and then give an alternative to it with captivity, I do however understand your point that maybe not all zoo's and other place like this are treating the animals fairly, maybe some are being abused, however this is not the fault of captivity, this is the fault of man. Basically my point is you should be arguing for Animals should not be kept in captivity, You are arguing that they should be treated better in captivity. Also who is to say that observing the animals in a captive environment is a bad thing, perhaps seeing these animals in zoos, is the only way some people might get to see these animals, should we deny access to such beautiful creatures to those who can not possibly see these animals in the wild due to disability or inability to travel? Millions of people visit the thousands of zoos around the world, proving that we simply never grow tired of observing wildlife. Finished
