The emergence of diseases in people can be significantly influenced by environmental degradation and climate change. Changes in climate can alter the habitats and behavior of disease vectors, such as mosquitoes and ticks, which can lead to the spread of infectious diseases. Increased temperatures can expand the geographical range of these vectors, allowing them to thrive in areas where they were previously not found. Additionally, extreme weather events, such as floods and droughts, can disrupt ecosystems and reduce biodiversity, potentially favoring the emergence of novel pathogens.

Environmental degradation, such as deforestation and pollution, also plays a critical role in disease emergence. It can disrupt natural habitats and bring humans into closer contact with wildlife, increasing the opportunity for zoonotic diseases (diseases that jump from animals to humans) to occur. Furthermore, changes in land use and agriculture, driven by climate change and environmental degradation, can result in increased human-wildlife interactions, further raising the risk of disease transmission.

In contrast, the other options mention aspects that generally do not contribute to disease emergence in significant ways. For example, increased rural employment may reflect economic growth and social stability, which often correlate with improved health outcomes. Higher education levels typically lead to better health awareness and practices, thereby reducing disease risk. Finally, stable
