Man's genius has with God's help produced marvelous technical inventions from creation, especially in our times.

Pope Paul VIMan is suddenly becoming aware that by an ill-considered exploitation of nature he risks destroying it and becoming in his turn the victim of this degradation.

This is a wide-ranging social problem which concerns the entire human family.
