Climate change is a long-term alteration in the statistical distribution of weather conditions over periods ranging from decades to millions of years. The world is currently experiencing a drastic change in temperature. This change can be felt in areas with tropical climates where the weather is getting hotter every day. Changes in global temperatures and precipitation over time are due to natural variability or human activity. It is also caused by the accumulation of greenhouse effects (Arrhenius, 1896). Should we, as humans, let this problem get worse? Climate change will affect everything, including humans, flora and fauna, and the environment. One of the effects of climate change is how it will affect people. Climate change will have a considerable impact on the health of the population. The health of the population will be mainly affected by air pollution and respiratory problems will present the greatest risk of health effects. Increased mold and pollen due to rising temperatures could also cause respiratory problems such as asthma in some people. If the effects of climate change were to become worse than they are now, people around the world would face serious problems. Food security will be affected and diseases can therefore be easily transmitted. Food- or water-borne illnesses are contracted by eating or drinking. For example, hepatitis A is a viral disease that interferes with liver function. It can be spread by consuming food or water contaminated with feces (CIA World Factbook, 2011). In addition to being infected with hepatitis A, people around the world can potentially be infected with hepatitis E, bacterial diarrhea, and typhoid fever. Climate change will also have an impact on the s...... middle of paper... ...it is unlikely that species of flora and fauna will have time either to adapt to this warming , or to adjust their distribution areas to follow the change in climatic zones. To conclude, global warming is already disrupting millions of people. lives daily in the form of destructive weather and habitat loss (Houghton, 2007). What is already happening is just the tip of the melting iceberg, as it is our children and grandchildren who could suffer the most from the effects of climate change. The effects of climate change are likely to be severe and irreparable. If we do not reduce the rate of climate change, hundreds of millions of people could be exposed to famine, water shortages, extreme weather and a loss of 20 to 30 percent of animal and plant species. If humanity has the capacity to destroy the planet, we can also help protect and preserve it..
