In the novel "Oryx and Crake" by Margaret Atwood, Crake explains to Jimmy the unsustainable nature of human reproduction in relation to limited resources. He highlights that mankind, unlike other species, does not restrain its reproductive habits even as food becomes scarce. This observation points to a fundamental flaw in humanity's approach to survival, as the increase in population cannot be maintained alongside decreasing food supplies.

Crake suggests that human beings cling to hope and imagination, even envisioning ways to escape death or prolong existence. This longing for immortality reflects a deeper psychological need to transcend limitations, implying that people are driven by a desire for continuity even in the face of dire circumstances. The conversation underscores a critical commentary on human nature and the fragile balance between resource availability and population growth.
