Impact on spheres
A cyclone such as 2B impacts the four spheres in many ways, since by affecting only one the others are
being impacted as well. First of all, let’s start where it all takes place: the hydrosphere and lithosphere.
These hurricane-type storms caused dreadful damage to the hydrosphere in many short and long term
consequences to these two particular storms. Along Bangladesh southern region there is a river delta
that was particularly impacted by the cyclone. It soon became a vulnerable spot since it laid in the
cyclone’s path, making it prone to the flood’s devastation. Some islands were entirely wiped out. Also, it
stratified the waters of the rivers, creating a midst of gigantic water confusion and polluted water. It also
moved huge quantities of sand, which even reshapes some of the coast. On the other side, several crops
were destroyed by the tides, leaving billions of victims to starve to death. However, not all was lost for
some soil still prevailed due to its previous abundance and fertility.
The way it impacts the atmosphere plays a total different role in the devastation. The winds were very
potent indeed, for they were potent in speed and intensity. The rainfall in the atmosphere is also
involved in this, for it was one of the main causes for precipitation. The air was also highly polluted due
to the debris and waste that was left behind. This rain and air pressure also triggered inland flooding,
which we have already been discussing about. Pressure was also impacted by the cyclone, since the air
pressure levels went to dangerously low level.
If all of these consequences impacted the lithosphere, hydrosphere and atmosphere greatly, the
biosphere was as devastated as any of the other spheres. It was specifically catastrophic the marine
ecosystems. The salt industry was impacted because of the ocean’s water exchange, and most of the
shrimp and fishes were lost. This represents a huge loss not only to the industry but also to the overall
ecosystem. As the majority of experts know, it has been proved that when several populations of
species that are fundamental to the food web the entire ecosystem is most likely to collapse due to a
lack of this heterotrophic level.
The marine environment was not the only one to be affected. Millions of cattle were lost, which became
another burden to the victims. But what weighed the most was the destruction of the communities and
houses. Billions lost their homes to the tides and floods, leaving them homeless and in a massive
wreckage. It has been estimated that the overall lose of all property was around $1.5 billion dollars. This
caused the expense for the building materials to rise up, making it more difficult for it to regenerate. The
casualties were numerous, including more than 135,000 deaths The majority of the victims were
drowned, making it difficult to find corpses. Those who were not killed by the cyclone also had to
encounter different health issues such as plagues and diseases.
Although all of these effects are catastrophic enough, there is one affair that remains untouched. By all
of these individuals factors Bangladesh is now in a higher risk of vulnerability. Even a simple tropical
storm could trigger some of these consequences, making it in an endless pattern of agony for those that
live in the coastal populations. Therefore it is important to take precautions when the alarms are fired
even if it is only a small warning, for even the smallest of the events can trigger these horrid
consequences.
