Climate change does not only raise the temperatures and it won’t bring us just warmer seasons. It will bring threats to our health.
Extreme weather conditions will appear more often and more frequent, such as hurricanes, floodings, and heat waves. Older people, children, pregnant women, homeless people, and people with certain medical conditions will be affected the most. Especially in developing countries and coastline areas will this be an issue.
Rising sea levels will destroy homes and affect the supply of fresh water. It will also heighten the risk of water-borne diseases and infections and other diseases spreading quickly over big areas. Also, the supply of medical and health services will be disrupted. People will have to wait to get food, water, and medical treatment. These are all essential and needed things in a functioning system.
Exposure to extreme heat can cause dehydration, heat strokes, cardiovascular, respiratory, and cerebrovascular diseases. Breathing problems, heart attacks, and apoleptic insults are the consequences.Furthermore, the high temperatures raise the ozone level in the air which will increase the breathing problems and heart attacks.
Another threat will be malaria and dengue fever. These diseases are influenced by the weather. Climate change will create perfect breeding conditions for mosquitos which then will spread the diseases. Malaria already kills almost 600,000 people every year and this number will increase.
According to the World Health Organization climate change is expected to cause 250,000 additional deaths per year from 2030 – 2050.This is based on the numbers of deaths due to malnutrition, malaria, diarrhoea, and heat stress. In addition that, the direct damages costs to health is estimated to be between US$ 2-4 billion per year by 2030. Health care will probably more expensive than ever and this will affect low-income people.
These are only a few examples of the effects climate change will have on our health. Unfortunately, there are a lot more, overwhelming negative effects. Of course we can try to adapt to those changes, but that won’t stop climate change. The people in countries with a weak health system—mostly developing countries—will suffer the most.
