The volunteers should also have only 7 days in which to collect all these animals.
Just a little correction to your theology.
The volunteers would not have to collect any animal.
Noah did not have to collect any animals.
They showed up when it was boarding time.
They also loaded themselves.
Gene 6:20 (KJV) Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every sort shall come unto thee, to keep them alive.
Gene 7:9 (KJV) There went in two and two unto Noah into the ark, the male and the female, as God had commanded Noah.
The animals showed up and went in.
God Bless,
