Climate change leads to warmer temperatures and increased rainfall, which creates favorable conditions for the breeding and survival of vectors such as mosquitoes and ticks. This results in an increase in the population of vectors and a higher risk of vector-borne diseases.

Air pollution has been linked to a number of health problems, including respiratory problems, cardiovascular diseases, and cancer. However, it has not been shown to improve cognitive function.

Climate change can lead to a number of stressors, such as extreme weather events, food insecurity, and displacement, which can increase the risk of mental health disorders such as depression, anxiety, and post-traumatic stress disorder.

Increasing the use of fossil fuels will worsen climate change and its associated health impacts. Investing in renewable energy, improving energy efficiency, and promoting sustainable agriculture are all ways to reduce greenhouse gas emissions and mitigate the health impacts of climate change.

The primary cause of climate change is human activities that release greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, into the atmosphere. These gases trap heat and cause the Earth's temperature to rise.
