Natural disasters-Increasing natural disasters

From definition of natural disasters to its causes,effects on human life,it's increasing numbers and frequency.
Today's Crunch Issue:
Natural disasters-Increasing natural disasters:
                                                                             A natural disaster is defined as a consequence when a natural calamity affects humans and/or the built environment such as drought,earthquakes,famine,extreme temperatures,flood,insect infestation,slides,volcanic eruption,wave/surge,wild fire,wind storm e.t.c.

       Now it is clear from the definition that a natural disaster is a natural calamity.So,responsible of natural disaster is nature.It is true to some extent,but natural disaster numbers,intensity and frequency is increasing every year.It is not that nature become cruel,but we are cruel to the nature.we(all human beings) are the main cause of all these increasing natural disasters.Today men are very advanced in every field,but these advancement also cause some natural problems to all of the earth planet.such as Global warming,ozone depletion,deforestation,increase in diseases,extinction of many plant and animal species and many other problems has been created for the whole mankind.The nature is not preserved in it's origional shape.
Natural disaster,intensity and frequency are not increasing itself.But it is increasing due to the above problems
(Global warming,ozone depletion,deforestation,increase in diseases,extinction of many plant and animal species e.t.c)as mentioned.And if men did not make any effort to control the above problems.There will be many more intense and greater number of natural disaster in the future.As scientist had already told of greater and more intense natural disaster in the future.
Increasing natural disasters:
Increasing natural disasters. With growing population and infrastructures the world’s exposure to natural hazards is inevitably increasing. This is particularly true as the strongest population growth is located in coastal areas (with greater exposure to floods, cyclones and tidal waves). To make matters worse any land remaining available for urban growth is generally risk-prone, for instance flood plains or steep slopes subject to landslides. The statistics in this graphic reveal an exponential increase in disasters. This raises several questions. Is the increase due to a significant improvement in access to information? What part does population growth and infrastructure development play? Finally, is climate change behind the increasing frequency of natural hazards?

Following step should be taken to minimize the natural disaster destruction:

  • Minimize the potential risks by developing disaster early warning strategies.
  • Prepare and implement developmental plans to provide resilience to such disasters.
  • Mobilize resources including communication and tele-medicinal services.
  • To help in rehabilitation and post-disaster reduction.
