The narratives of The Handmaid's Tale name several environmental changes with impact on the ecological and political situation of the pre-Gileadean United States of America.
Global Warming Edit
According to the title of a book by Joseph Lawrence, global warming had a serious impact on American prosperity (See Commander Lawrence's Bookshelf).
The Republic of Gilead responded to these climate changes by reportedly reducing its carbon emissions by 78% in the first three years of its existence.
In the alternate reality of the narrative, large territories of the continental United States, referred as the Colonies
, have been heavily polluted for decades by pesticides and radioactive fallout
The religion-based ideology of Gilead sees infertility as a penal "plague"
sent by God, in response to air pollution "with chemicals and radiation and poison"
