Climate change is becoming an ever-growing threat to human health and biology. Research an incident from within the last 5 years where climate change has impacted a population of humans in a biological sense. This can include changing patterns or incidences of disease, or a new disease spreading; impacts on health and nutrition due to drought; impacts on health and mortality due to extreme weather (hot or cold); etc. News articles are acceptable sources, as are scientific journals. In your response be sure to describe the population (where they live, who they are), the way the climate has changed around them, the biological impact of the climatic change, and if applicable, ways that that population is dealing with the new threat to human health and biology.
