Constant Climatic changes pose a great challenge to Human Health. Even though toxins and disease pathogens are a threat to health, Climate change may cause health effects that are potentially harmful. These threats include impacts from heat waves, air pollution that causes ailments, severe storms and many infectious diseases.
Assessing the glaring effects of climate change to human health should realistically include setting up a capacity to manage the unpredictable climate conditions. Due to the health risks occasioned by the climatic change, there is needed to set up and run a vibrant public health infrastructure.
Since we live in a global village, increased of risks associated with diseases emanating from other countries should be considered. Climate change has made poor countries suffer greatly. Due to global trade that requires a lot of travelling between different countries, diseases are bound to flare-up in any part of the world. Extreme climatic conditions such as severe draught and storms also undermine the public health infrastructure that is in place.
It is worthy noting that;
• There has been a significant increase recorded in illness and death that has been caused by extreme heat waves. There is also death caused by extreme cold weather.
• It will be difficult to protect human health because set air quality standards won’t be met due to Warming of the environment.
• Weather conditions that are extreme have caused physical and psychological problems to mankind. This has led to stress and depression related ailments.
• There is a marked increase in diseases that are transmitted by water, food and insects.
• Due to rising carbon dioxide concentration and temperatures, production of pollen is increased hence a number of plants with high rate of allergenic pollen have a prolonged pollen season. This presents a health risk to human beings.
Environmental contamination and emergence of infectious diseases has caused public health concerns world wide. Health threats have also affected the relationship between human beings with physical, biological and chemical conditions of our natural environments.
Over population has exerted pressure on health facilities and made it extremely difficult to maintain a sustainable public health policy and practice. Zoonotic and vector- borne ailments, airborne contaminants, Water contaminants and bio – accumulative contamination in the food chain have caused public health threats all over the world and require concerted efforts to develop solutions that are scientifically viable.
There is therefore need to understand as a prerequisite the ecological and environmental health so as to protect public health. Our scientists play an important and significant role in ensuring that our country has relevant scientific information and knowledge that will help us understand diseases that are a constant threat to human health and come up with preventive measures.
