‘natural’ hazards, we mean things that happen as part of nature like earthquakes and fl oods. ‘Human-made’ hazards, for the purposes of this fact sheet, are hazards that are created by people, such as petroleum products and hazardous substances.

What Man Causes To Nature: Natural Disasters.
Scientists state that human activities have become a trigger for many natural disasters. Do scientists big up our influence on nature or not? All kinds of human activities leave the indelible imprint on nature, whether we like it or not. Scientists focus extensively on estimating the level of human engagement to the occurrence of natural disasters.
Some people still doubt that humanity is able to influence nature to that extent; however, pallid statistics claim the opposite. The Centre for Research on the Epidemiology of Disasters CRED has been studying this issue human causing natural hazards over 40 years and has published the report according to which within 19 years 6, natural disasters took 1. The number of reported natural disasters increases every year.
One of the reasons for it is the development of the data collection methods and raising awareness of different agencies that actively search for information about natural disasters.
However, the main reason is the increasing number of hydro-meteorological disasters: droughts, floods, typhoons, etc. Within 20 years the number of such disasters tripled from to per year. It is telling that the number of natural geological disasters that cannot be influenced by humans volcanic eruptions, landslides, etc, human causing natural hazards.
remained the same. We used to blame climate change as a reason for all the natural disasters. However, it seems that humanity conceives disasters as a new DIY project, human causing natural hazards. So what human activities can have an impact on natural disasters?
When do the rivers start to flood? Usually, it happens when the water starts to overflow the banks of the river and spreads out onto the surroundings. There may be several reasons for it:. All these are the natural factors that increase the possibility of the flood. But how can human increase the possibility of a flood? Here is a list of activities that are responsible for it:. Deforestation is rightfully considered to be one of the most destructive activities. People destroy vegetation that protects the topsoil and absorbs excess rainwater with its roots.
As a result, high water freely spreads in the region leaving less time for rescue activities. Agriculturesimilar to deforestation, destroys the topsoil so it has to possibility to absorb rainwater. Consequently, more water will wash into human causing natural hazards riverbed and the water system becomes overloaded.
The water level rises and that inevitably leads to floods. Urban development is another aspect that increases the possibility of flooding. First and foremost, all the surfaces in the town or city are covered with cement or asphalt.
Naturally, these materials do not absorb rainwater human causing natural hazards it has to search human causing natural hazards the remaining water channels. Any blunder in the venting system may lead to the water spill over. In addition, levees are often used as a way to gain more land for a settlement. One of the downsides of levees is the water level rising in the rivers near the cities.
Potentially, human causing natural hazards, the levees issues may human causing natural hazards a huge flood when all the excess water that was restrained by the levees starts to spread in the surroundings. Same is with the destruction of the natural wetlands. People ditch swamps, destroy natural obstacles for watercourses and water collection areas. As a result, excess water finds new ways and they all trend near or through human settlements, human causing natural hazards.
Hydroelectric power is impossible without dam constructions, human causing natural hazards. Apart from the dangers of earthquakes, dams can cause floods. The whole process of obtaining electric power through the water power plant requires a huge reservoir of water which flow is thoroughly regulated.
Any miscalculation may lead to the catastrophe. Earthquakes : One of the recent examples is the earthquake in China in Newly created Zipingpu Reservoir contained million tons of water that and all that weight pushed on the crust fracture. It took more than 1, lives and damaged more thanhouses and buildings. Dams : Banqiao Dam in China collapsed in claimed more thandeaths. Avalanches : In the Philippines have witnessed one of the most disastrous avalanches in history.
A rockslide leveled a mountain village Giunsaugon to the ground killing thousands of people. The reason for it was uncontrolled deforestation and mining around the village. Landslides : On 20 th December a landslide in Shenzhen killed 70 people and destroyed 14 factory buildings, human causing natural hazards. The reason for it was an artificially made dump of the excavated soil with a height over meters that was brought down by the heavy rain.
All the examples depicted above show that the reason was human activity, be it faulty levees system or incogitant deforestation. Saved human causing natural hazards, well-thought-out draining systems in the settlements, correct placement of dams or scrupulous regulation of mining and fracking could save thousands of lives. All in all, the increasing number of disasters that are caused or worsened by humans is a warning sign, human causing natural hazards.
Rising awareness and engagement of the governmental agencies is the only way to improve the situation and flesh out a more responsible way of the interaction with nature.
Otherwise, the situation will worsen every day causing more and more deaths of the civilian population. Need a stunning essay on human activities that have impact natural disasters?
