A method and means for transporting a quantity of comestibles (preferably at lowered temperatures) where at least continual monitoring of at least the oxygen level of the atmosphere to which the comestible is subjected is carried out. Preferably the carbon dioxide level is also monitored. Automatic adjustment of the oxygen content and carbon dioxide content in response to the monitoring is carried out using a positive infusion of ambient air and the scrubbing of the gas atmosphere to which the comestibles are subjected respectively. Ideally the comestibles are of a respiring nature such as would be the case with plants (whether cut or uncut), fruit and vegetables and they are carried in a container suitable for shipping where a seal of the container sufficient to ensure that less oxygen from the ambient air can diffuse into the container than is required for respiration by said quantity and sufficient to ensure a product of carbon dioxide by said quantity as a result of respiration than can diffuse from the container.

A shipping container adapted for having a quantity of respiring comestibles selected from plants, fruit and vegetables disposed and sealed therein sufficient to insure that less oxygen from the ambient air can diffuse into the container than is required for respiration by said quantity and sufficient to insure a production of carbon dioxide by said quantity than can diffuse from the container, means to monitor the temperature of the environment within said container, means to monitor oxygen content within said container, means to monitor carbon dioxide content within said container, means responsive to the means to monitor the temperature of the environment within said container to adjust at least downwardly the temperature of the environment towards a predetermined value, means responsive to the means to monitor the oxygen content within the environment of said container to cause a positive infusion of ambient air into said container should the oxygen level within the environment fall below a predetermined value, and means responsive to the means to monitor the carbon dioxide within the environment to cause the passage of gas within the envorinment through means to scrub at least some carbon dioxide from the atmosphere of the environment should it rise above a predetermined value.
