Alarming Fertility Drop: Chemicals Plus Climate Change
27 Apr
Summary
- Combined chemical and climate stressors cause alarming fertility decline.
- Endocrine disruptors and heat stress impact fertility across species.
- Urgent action needed to curb chemicals and climate change.

A comprehensive review of scientific literature reveals that the combined effects of toxic chemicals and climate change are likely driving a significant global drop in fertility. Organisms worldwide, from invertebrates to humans, face reproductive harm from endocrine-disrupting chemicals found in plastics and everyday products, alongside environmental shifts like increasing heat stress.
While the individual impacts of these stressors are known, their simultaneous exposure creates an additive or synergistic effect, intensifying reproductive issues. Experts express alarm over this dual threat, noting that chemicals like phthalates and PFAS, and climate impacts such as rising temperatures, disrupt hormones and impair fertility across diverse species.
This research highlights the pervasive nature of these issues, with similar harms observed across different taxonomic groups. Addressing this global challenge necessitates immediate action to reduce the use of toxic chemicals and mitigate climate change, as exemplified by international efforts to ban harmful substances.
