What are hazards of population explosion?
Increased Risk of Infection Urban crowding and changes in the environment due to over-exploitation of resources by humans can lead to the emergence of various infectious ailments. Also, antimicrobial resistance can lead to bigger and life-threatening issues.
How many people live in hazardous areas?
Around 500 million (in 2000) people live on or close to volcanoes. By 2025 it is estimated that 600 Million people will be living in tectonically active areas. For example, 961,000 people live in Naples, Italy, despite being at the foot of the dangerous Mount Vesuvius.
How do natural hazards affect population?
In addition, disasters can lead vulnerable populations to suffer permanent injury which may reduce their capabilities, and even decrease the ability to work, to live independently and care for themselves [3].
What are the hazards in the world?

What is an example of overpopulation?
Overpopulation cause pollution. Mexico city, for example, is overpopulated and air pollution is an issue. When you wait longer with your car, you cause atmospheric pollution. In some instances, overpopulation cause wars and conflicts (such as some parts of Africa).
What is a hazard prone area?
The mortality risk due to hazards in a geographic area is the product of the probability of a hazard taking place in that area and the average vulnerability to hazards. An area is defined as hazard prone area if the mortality risk is higher than a certain threshold.
What is population density near a hazard event?
Population density – the greater the number of people in an area the greater the potential for disaster. Magnitude – the size of the event massively affects the impact it has. Every step up the Earthquake Richter scale represents a 31 fold increase in energy released. Frequency – how often the hazard occurs.
What type of hazard is virus?
Biological hazards include bacteria, viruses, fungi, and other living organisms that can cause acute and chronic infections by entering the body either directly or through breaks in the skin.
