Every day we witness sudden temperature changes and the natural disasters that occur as a result of them. In particular, the warming of the seasons can be observed as weather changes. Temperature changes are the result of human activity in such a way that harmful substances are released into the environment by human activity, resulting in global warming. In order to talk about climate change, a long-term study of temperature changes, climate, pressure and the resulting consequences is necessary. The consequences of climate change are studied in the environment, where animal and plant ecosystems are disturbed and have a negative impact on human life and health. Climate change can cause various diseases in humans that can be contagious or non-communicable. The exceptional impact of climate change on human health is manifested in the occurrence of cardiovascular diseases. Extremely high or low ambient temperatures, air pollution, harmful substances created as a result of forest fires are only some of the causes that can lead to morbidity or mortality of people. A special response to climate change is shown by people with pre-existing comorbidities, elderly people and small children whose bodies are sensitive to very high or low temperatures. By preventing a vulnerable population sensitive to climate change and by influencing the reduction of climate change, by raising awareness of the importance of nature protection, it is possible to significantly influence the slowing down of global warming and thereby prevent the morbidity and mortality of mankind when it comes to cardiovascular diseases.
