While climate change can indirectly lead to mental health problems, such as anxiety and depression, due to the stress of dealing with its impacts, it is not a direct impact in the same way as the other options.

All of these population groups are more vulnerable to the health impacts of climate change due to their weaker immune systems, reduced ability to regulate body temperature, and increased susceptibility to disease.

Climate change can affect the spread of waterborne diseases through all of these mechanisms.

Allergies are not a mental health impact of climate change, although they can be exacerbated by climate change-related factors such as increased pollen production and air pollution.

Climate-related stress is the term used to describe the process by which climate change can indirectly lead to mental health problems, such as anxiety and depression, due to the stress of dealing with its impacts.

Ignoring the problem of climate change will only make its health impacts worse. Reducing greenhouse gas emissions, investing in climate adaptation measures, and promoting healthy lifestyles are all ways to reduce the health impacts of climate change.

Climate-related disease transmission is the term used to describe the process by which climate change can lead to changes in the distribution of diseases, such as the spread of mosquito-borne diseases to new areas due to changes in temperature and precipitation patterns.

Hypothermia is a condition that occurs when the body loses heat faster than it can produce heat, leading to a dangerously low body temperature. It is not a health impact of extreme heat events, which are characterized by high temperatures.

Climate-related extremes is the term used to describe the process by which climate change can lead to changes in the frequency and intensity of extreme weather events, such as heat waves, droughts, floods, and wildfires.

Ignoring the problem of climate change will not protect you from its health impacts. Staying hydrated, wearing sunscreen, and seeking shelter from extreme weather events are all ways to protect yourself from the health impacts of climate change.

Climate-related food insecurity is the term used to describe the process by which climate change can lead to changes in the availability and quality of food, making it more difficult for people to access enough food to meet their needs.

Cancer is not a direct health impact of air pollution, although it can be exacerbated by air pollution-related factors such as inflammation and oxidative stress.

Climate-related vector-borne disease transmission is the term used to describe the process by which climate change can lead to changes in the distribution of vector-borne diseases, such as the spread of malaria to new areas due to changes in temperature and precipitation patterns.

Ignoring the problem of air pollution will only make its health impacts worse. Reducing emissions from vehicles, promoting the use of renewable energy sources, and planting trees are all ways to reduce the health impacts of air pollution.

Climate-related disaster risk is the term used to describe the process by which climate change can lead to changes in the frequency and intensity of natural disasters, such as floods, droughts, and wildfires.
