1. Human and non-human animals live in a finite world. Whether the oceans the sky or a landmass, there is only so much space. The human animal is an effective competitor and has a continually expanding population. As the human animal population expands it collapses the volumes within which non-human animals live. This displaces non-human animals. As such, all non-human animals live in continually shrinking spaces.
2. All spaces occupied by non-human animals are designed (affected) by humans. The spaces occupied by non-human animals have a variety of names: zoo exhibit, conservation area, protected area, island. These spaces have “inputs” and “outputs”. Regardless of name or designation zoo exhibits and conservation areas are the same – designed and shrinking spaces, with controlled quantity and quality of inputs and outputs, and a finite number of non-human animals that can be supported.
3. Animals can thus occupy displaced ecologies or in situ ecologies. In situ ecologies, for the time being, require less intervention from human animals to maintain. A green roof, a fish tank, a zoo exhibit are all displaced ecologies. The care and maintenance of displaced ecologies require more resources than in situ (connected) ecologies.
4. Human animals control the quantity and quality of inputs and outputs for non-human animal habitats. In a sense all animal spaces have “bars” that regulate – some things are kept out and some things are allowed through.
5. If the quality of input is less than optimal for a given non-human animal species this is a form of “competition”. Pollution is a form of competition. Waste is a form of competition. Noise is a form of competition.
6. Ultimately, all non-human animals will be faced with extinction, captivity or domestication.
7. When engaged in competition human animals usually choose themselves over non-human animals.
8. We are all animals and subject to the laws of ecology. The world can survive without economy but it cannot survive without ecology. Ecology trumps economy.
9. Given the above the issues relevant to zoos and “captivity” are the same for “the wild” and conservation areas. Human animals need to think more holistically and along longer time frames.
10. The number and diversity of non-human animals should be viewed as positive correlate of the probability of human animal survival.
