The environments that we used to see have occurred
in this world for many centuries ago. Environments are composed of two main
parts which are the living and non-living or also known as biotic and abiotic
components. Living parts of the environment are animals, plants, bacteria,
viruses, fungi and other living organisms. For the non-living parts, they
consist of the physical and chemical factors in the environments that affect
the ecosystems such as temperature, soil acidity, light, radiation, water and
so on. The environments were in a very stable state before however when they
are interrupted and exploited by human, the environments have changed and many
disasters have occurred. The population of certain living organisms such as
panda, Sumatran rhinoceros, Sumatran tiger and many more are nearing the risk
of getting extinct.
All
the components in environments play important role to maintain the environment
in stable and balanced state. For example, the sun provides light energy for
the human to be able to see colours, source of energy for plants to carry out
photosynthesis and more whereas plants will provide oxygen and source of food
for the animals as well as human. When the plants died, they will rot and turn
into nutrients that help to increase the soil fertility. However, due to
human’s ego in going for industry, deforestation, urbanization and so on, the
balance within ecosystems has been disturbed. Due to that, many disasters and
diseases happened and it showed that the environments are trying to punish
human by creating all of these. The environments are trying reminding the
responsibilities of human towards the Mother Nature which are taking good care
of the environments and not to interrupt the balance of the ecosystems. The Mother
Nature is trying to warn and remind us that who is the one that giving order by
creating disaster and diseases that bring harms to human.
One
of the examples for the punishment from the environment is the landslide.
Landslide is a geological phenomenon which includes a wide range of ground
movements, such as rockfalls, deep failure of slopes and shallow debris flows,
which can occur in offshore, coastal and onshore environments. Although the
action of gravity is the primary driving force for a landslide to occur, there
are other contributing factors affecting the original slope stability.
Typically, pre-conditional factors build up specific sub-surface conditions
that make the area or slope prone to failure, whereas the actual landslide
often requires a trigger before being released. The contributing factor is the
deforestation by human being. This activity has being carried out by human
being for many years as many profits can be earned by cutting down the trees
and sold them in the form of timber as raw materials for many commercial
products. However, at the same time, the soils loss their support from the
roots of the tree and become easily mobilize due to the deforestation and the
situation even worse when the area involved is at the slope or small hills.
Landslide can bring many effects to human as it can damage the properties,
cause injury and even death in addition to affect number of resources such as
water supplies, waste disposal system and more.

Besides
that, dengue fever is another example showing that the environments are trying
to punish people by causing loss of their life. Dengue fever, also known as
breakbone fever, is an infectious tropical disease caused by the dengue virus.
Symptoms include fever, headache, muscle and joint pains, and a characteristic
skin rash that is similar to measles. In a small proportion of cases the
disease develops into the life-threatening dengue hemorrhagic fever, resulting
in bleeding, low levels of blood platelets and blood plasma leakage, or into
dengue shock syndrome, where dangerously low blood pressure occurs. Dengue is
transmitted by several species of mosquito within the genus Aedes, principally
A. aegypti. Recently, the human populations that are having this fever have
increased in amount and we can relate it to the human activities such as
littering. Littering at anywhere will provide good bedding for the mosquito
Aedes to grow as water will accumulate and it is suitable for them to lay egg.
This will indirectly increase the population of particular mosquitoes and thus
increase the chance for transmission of dengue fever.
