Question

Explain two human developments that would increase the risk of people being affected by natural hazards.

Answer 1

Two human developments that would increase the risk of people being affected by natural hazards:

Development of Refineries:

• Refineries burn fossil fuel, which results in a great release of toxic substances into the atmosphere.

• This is referred to as air pollution. These wastes are classified as CFC's (chlorofluorocarbons) they attack the molecules of ozone in the atmosphere, which releases much oxygen to the earth, but leaving less and less ozone molecules which protect the earth from direct effects of the sunlight.

• These effects include increase in temperature which negatively affects the ice that is stored in the North and South region of the earth

Development of rural areas

• This is a subtle means of natural hazard, because during urbanization, many species of plants and even some animals are destroyed.

• It is a natural hazard, because these plants or animals might prevent some certain things from happening.

• For example, grasses stops water erosion, trees serve as wind breaks to prevent wind from becoming sand storms
