The purpose of this episode is to discuss the impact climate change has on food and food stability. While listeners are familiar with the basic science of climate change, this episode is meant to serve as the introduction to the wide array of subtopics that climate change intersects throughout the world. We will discuss the impact climate change has on agriculture and water availability, how island and urban communities can respond to climate change, and what steps should be taken as an individual to address the impending effects.

The purpose of this episode is to share an in-depth analysis of how climate change has impacted global health and provide next-step solutions that listeners can implement in their daily lives. We will introduce topics such as the impact of climate change on available drinking water, why climate change is increasing the geographic spread of diseases, and how the health community is responding to these changes. At the end of this episode, we hope that listeners will have had an introduction to an increasingly important angle of climate change that needs to be addressed.
