In 1939, Swiss chemist Paul Müller discovered DDT (dichloro-diphenyl-trichloroethane), a synthetic pesticide that would revolutionize agriculture by enabling large-scale pest control. DDT's effectiveness in increasing crop yields made it a widely adopted solution during the mid-20th century, particularly in post-war agricultural practices. However, its later association with environmental harm and health risks led to significant regulatory changes and a reevaluation of pesticide use, highlighting the complex relationship between agricultural innovation and ecological sustainability.

The development of synthetic pesticides like DDT in 1939 sparked environmental awareness, influencing poetry by writers such as Rachel Carson. Their works highlighted nature's fragility, urging readers to consider the consequences of human intervention, thus laying the groundwork for the eco-poetry movement.
