poly

Polygamy is a normal thing that we can consider it in Africa?

Recently I thought about it and I came to the conclusion that:

Be POLIG in Africa is the only spsosob survival, Meic one woman is not enough teeth prrzezyc tapes.

Eg. How one woman can carry a bucket of water, for example, or perform other actions? she can not do it because there is no time for it and are just needed two people /

However, in Europe, it seems to me that something like this can not be accepted because of an development of the child, if he could have two mothers and one father?
