Scarcely does a day pass when a natural disaster does not take place. Floods, hurricanes, harsh weather patterns, earthquakes, and avalanches are some of the natural disasters that take place round the world. However, the geographical studies – physical and human – show that these disasters are brought due to the over exploitation of the resources by the human beings. In some cases, they are out of human control. But in most of the cases the disasters are caused by the lack of geographical understanding and the lack of knowledge of the safe limits of nature’s exploitation.
Knowing the increasing natural disasters which are wreaking havoc on humanity, it is important to study these natural disasters and their reasons. The following paragraphs will give the details of some natural disasters caused by the human neglect of nature and its laws.
Hardly is there any serious natural disaster then the increasing global warming. The term global warming refers to the increasing temperature of the globe due to the addition of more greenhouse gases then the nature’s carrying capacity.
Global warming takes place due to the addition of the greenhouse gases like carbon Di oxide, methane, Nitrogen Di oxide, and CFCs through industry. It is said that the concentration of these gases has increased manifold due to the increase in the industry and use of Coal.
Consequently, the world has become a hotter place, triggering many natural disasters like unpredictable weather patterns and rise in the sea levels. Moreover, the heavy rains and melting of the glaciers is also part of these disasters.
Another natural disaster which has engulfed the world is the acute shortage of water. Water being the prime necessity of humans is decreasing drastically due to the over exploitation of this resource. The national geographic magazine in its March 2010 edition showed the grave concern over the increasing scarcity of the precious resource. According to it, Africa is facing the worst shortage where people have to walk for kilometers to fetch water even for drinking purposes let alone the other usages.
Loss of biodiversity
Biodiversity refers to the number of species – fauna and flora - at the particular place. It adds beauty to a place and gives it a special touch. Unfortunately, the world biodiversity is decreasing day by day, for the forests are being cut in order to set up industries and other human settlements.
Biodiversity is of great use for humanity. It makes the environment in equilibrium. Besides, many species of flora and fauna are beneficial for human health. However, the cutting of forests is leading to the loss of biodiversity which in consequence trigger natural disasters.
Mass wasting is also among some natural disasters which are against the human survival. Sometimes, mass wasting leads to little tremors of earthquake, while some other times, it leads to the blockade of roads and communication highways.
It is the result of cutting of forests without plantation. Consequently, the surface becomes porous and rough, increasing the silting in rivers and dams. Mass wasting is also triggered by the indiscriminate cutting of forest.
The 21st century has witnessed the acme of development. But at the same time, it has also witnessed some worst natural disasters like global warming, mass wasting, loss of biodiversity, and water shortage. These disasters are because of the indiscriminate usage of resources by human beings. However, mankind will have to mend its ways, if it wants a better future for coming generations.
