How do natural disasters affect the world?

Hint: Natural disasters are devastating events that occur as a result of volcanic, geographical, or hydrological factors which can result in deaths, property destruction, and social and environmental disturbance. It includes floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunami and storms etc.

Complete answer:
- Natural disasters affect millions of people every year, and their consequences can be disastrous. Natural disasters can devastate entire countries in an instant, from the collapse of buildings to the spread of disease. Tsunamis, earthquakes, and typhoons wreak havoc not just on land, but also on people's lives in both densely populated cities and rural villages.
- Population relocation is one of the most immediate consequences of natural disasters. When countries are devastated by earthquakes or other natural disasters, many people are forced to flee their homes and seek refuge in other areas.
- Flooding can cause stagnant water, which encourages bacteria to breed and malaria-carrying mosquitoes to breed causing health problems.
- Food is often scarce following natural disasters. Thousands of people go hungry around the world as a result of crop destruction and lack of food resources, whether it occurs immediately during a flood or steadily during a drought.
-Many children experience post-traumatic stress disorder (PTSD), a severe psychological illness caused by intense trauma when they are exposed to scenes of devastation and the deaths of friends and loved ones.

Note:
- According to a United Nations study from 2014, disasters have impacted 4.4 billion people worldwide since 1994, claiming 1.3 million lives and causing US $2$ trillion in economic losses.
- Following natural disasters, women and children in developing countries are frequently the most vulnerable population groups.
- The Philippines is home to eight out of ten of the world's most vulnerable cities to natural disasters.
