Dealing with the problem of animal waste has been studied. We must remember that Noah and his sons were smart people, and that they had a long time to prepare for the voyage. Extensive planning took place. Part of this planning was to design suitable enclosures for different types of animals, and to design them with labor-saving features in mind. It would not be possible to clean each cage individually, nor would it be necessary if enclosures such as those mentioned on the slide were employed.

Pests such as insects and rats could have been controlled through the use of ducks, cats and other animals that effectively control pest populations. Even though Noah is told to take two of every type of animal, this should be regarded as a MINIMUM, and does not prevent him from taking, say, dozens of ducks and cats on board.

Earthworms provide another solution for getting rid of waste materials (they are natural biologic agents for the immediate biodegradation of manure).
