Crowding.
Crowding is the situation in which case a large number of animals, including man, are restricted in environmental space. Such an occurrence may start with just a few animals. In plants, including bacteria in culture, agriculture may be considered as an artificial example of this process. We see the ontogenic forms of crowding developing from stress into superorganisms (such as certain social insects) and from stress into pathological crowding in animals, plants and man. Crowding is shown by environmental changes such as in the introduction of new species of certain rodents and lagomorphs into the Australian environment. Aspects of crowding play a role during the housing of zoos, domestic or laboratory animals. Space limitations and overpopulation initiates stress and infections such as tuberculosis and tumours. This is found in man himself in the development of slums through to urbanisation as seen in Asia particularly, in prisons, in the workplace, in the school or home.
