Climate change can impact the spread of diseases and pests in several ways. Warmer temperatures can expand the range of disease-carrying organisms like mosquitoes, allowing them to thrive in new regions. Changes in precipitation patterns can also create ideal breeding grounds for pests and pathogens. Additionally, extreme weather events such as hurricanes and floods can disrupt ecosystems, leading to increased transmission of diseases. Overall, climate change can contribute to the proliferation and spread of diseases and pests, posing risks to human and animal populations.
