The topics of climate change and ecosystem disruption are at the forefront of global discussion. Accordingly, there is a sense of urgency among citizens, environmental experts, and political leaders for action and policy change. While the effect of a changing climate on the environment is well recognized, its impact on the human body has not been sufficiently described. In our review, we will attempt to outline some of these effects. We will discuss how the recent surge of immunologic disease may be related to the changing profile of microorganisms and antigens in our every-day environment. We will explore how the introduction of antibiotics may result in an altered gut microbiome, and subsequently abnormal neurodevelopment. Finally, we will discuss a possible link between chemical preservatives and neoplastic disease.
