Researchers find ‘alarming’ effect on fertility across global species from simultaneous exposuresSimultaneous exposure to toxic chemicals and climate change’s impacts likely generates an additive or synergistic effect that increases reproductive harm, and may contribute to the broad global drop in fertility, new peer-reviewed research finds.The review of scientific literature considers how endocrine-disrupting chemicals, often found in plastic, coupled with climate change’s effects, such as heat stress, are each linked to reductions in fertility and fecundity across global species – including in humans, wildlife and invertebrates.
