Answer:
TITLE: CLIMATE CHANGE
Introduction
Climate change refers to the long-term changes in the climate that occur over decades, centuries or longer. It is caused by rapidly increasing greenhouse gases in the Earth’s atmosphere due primarily to burning fossil fuels (e.g., coal, oil, and natural gas).
These heat-trapping gases are warming the Earth and the Oceans resulting in rising sea levels, changes in storm patterns, altered ocean currents, changes in rainfall, melting snow and ice, more extreme heat events, fires, and drought. These impacts are projected to continue and in some cases, intensify, affecting human health, infrastructure, forests, agriculture, freshwater supplies, coastlines, and marine systems.
BODY
People can become ill if exposed to contaminated drinking or recreational water. Climate change increases the risk of illness through increasing temperature, more frequent heavy rains and runoff, and the effects of storms. Health impacts may include gastrointestinal illness like diarrhea, effects on the body's nervous and respiratory systems, or liver and kidney damage.
Climate impacts can affect exposure to waterborne pathogens (bacteria, viruses, and parasites such as Cryptosporidium and Giardia); toxins produced by harmful algal and cyanobacterial blooms in the water; and chemicals that end up in water from human activities.[1]
Changing water temperatures mean that waterborne Vibrio bacteria and harmful algal toxins will be present in the water or in seafood at different times of the year, or in places where they were not previously threats.
CONCLUSION
Natural systems around the world are being affected by regional climate changes, particularly temperature increases, and that these temperature increases are very likely to be the result of anthropogenic emissions of greenhouse gases.
