The greatest danger to human health in the current world is not atomic but it is Air pollution and climate change. In recent years the world has seen a change of climate conditions that have impacted the natural way of life such as rainfall patterns. NASA researchers have found that the surface of the planet is warming, and many of the hottest years on record have occurred in the last two decades. The warm weather has been a result of the air pollution happening in the world. Therefore this analysis will discuss air pollution and climate change as the greatest danger to human health in the world today.
Climate change and air pollution lead to high temperatures. Exceptionally high air temperatures, especially among elderly people, directly contribute to fatalities from respiratory and cardiovascular diseases. Ozone levels and other air contaminants that intensify respiratory and cardiovascular conditions are also exacerbated by high temperatures. In intense temperatures, pollen as well as other aero-allergen levels are also greater. These can cause asthma, affecting about 300 million individuals. It is expected that continuing temperature rises would exacerbate this pressure.
Internationally, the amount of weather-related natural disasters recorded has almost multiplied since the 1960s annually, such as disasters result in more than 60,000 fatalities mostly in underdeveloped nations. Increasing extreme weather events as well as rising sea levels households, healthcare centers, and other vital resources get destroyed. People can be required to move, which in turn raises the risk of developing certain types of health consequences, from mental illnesses to communicable illnesses. Freshwater sources are likely to be affected by highly erratic rainfall trends. Lack of clean water can threaten hygiene and raise the chances of diarrhea disease, which annually kills more than 500,000 children as young as 5 years. Water shortage contributes to drought and starvation in extreme situations. Climate change is likely to cause the severity and frequency of droughts on a global and regional scale by the end of the 21st century. wa floods and intense rainfall are also increasing in severity and frequency. Floods pollute water resources, increase the risk of infectious diseases, especially waterborne, and establish breeding sites for pests transporting illnesses such as mosquitoes. In the majority of the poorest areas, rising temperatures and unpredictable rainfall are likely to reduce the yield of food products. This will raise the risk of anemia and under-nutrition, causing many deaths yearly.
Climatic conditions highly impact waterborne illnesses and the virus is spread by snails, insects, or other cold-blooded animals. Global warming is expected to extend the transmission seasons of major vector-borne diseases and also to change their geographical distribution. The climate also heavily influences the outbreak of malaria. Malaria is spread by Anopheles mosquitoes, and it leads to the death of more than 400 million people per year in some African nations, mostly below the age of 5 years. The Aedes dengue mosquito vector is also extremely susceptible to climate changes, and research shows that it is probable that changing climate will keep increasing dengue exposure. It thud further indicates that climate is a major problem that has impacted the health of many people across the world.
Changes in water temperatures indicate that Vibrio waterborne bacteria and toxic algae contaminants are present in seafood and water or in areas at various times of the year where they have not traditionally been threatened. Water bodies used for leisure raw fish fishing reservoirs and waters, of drinkable water would be rapidly polluted by flooding and runoff leading to increased extreme rainfall, and storm surge. Extreme weather conditions and severe storms can harm or surpass water infrastructure capability (such as wastewater treatment plants), thus raising the risk of pollutants becoming exposed to citizens. The increased levels of temperatures can lead to a surge in cases of Salmonella as well as another food poisoning due to bacteria since bacteria develop more quickly in warmer climates. These diseases might cause gastrointestinal discomfort and, in extreme cases, death. Food safeguarding activities can help prevent these diseases even as the temperature rises. Climate change might have a number of impacts of which might raise the risk of exposure to chemical pollutants in food. For instance, higher ocean temperatures can contribute to increased mercury concentrations in seafood, and changes in severe weather events by stormwater runoff can add pollutants into the food chain. For certain plants, higher amounts of carbon dioxide in the atmosphere can serve as a nutrient, but low levels of proteins and important minerals in crops like potatoes, rice, and wheat, make these foods less nutritional.
The planet has seen a shift in weather conditions in recent times that have changed the normal way of life, such as seasonal rainfall. Climate change refers to a change over an extended period of time in normal weather conditions, such as rainfall and temperature in a region. NASA researchers also found that the planet’s surface is warming, and in the last two decades, several of the hottest years on record also occurred.
