What does it means by extinction? Wikipedia defines extinction in
terms of biology and ecology as the end of an organism or a group of organism,
normally a species. The moment of extinction is generally considered to be the
death of the last individual of the species, although the capacity to breed and
recover may have been lost before this point. Besides of this fact, there are
10 most amazing extinct animals which are Tyrannosaurus Rex (extinct 65 million
years ago), Quagga (extinct since 1883), the Tasmanian Tiger (extinct since
1883), Steller’s Sea Cow (extinct since 1768), Irish Deer (extinct about 7,700
years ago), Caspian Tiger (extinct since 1970), Aurochs (extinct since 1627),
Great Auk (extinct since 1627), Cavelion and Dodo (extinct since 17th
century).
One of important question
that should we asked ourselves is what are the reasons that lead to animal
extinction? The answer could be lack of consideration in appreciating animals and the importance to
preserved them. This is what might happened to Dodo bird in Mauritius. The
Dutch and Portuguese brought along with them hungry convicts and sailors that
killed it for food. Not only that, the unfortunate bird faced breeding threat
when the introduced animals such as monkey, dogs and rats destroyed their eggs
in the ground. Nowadays, the same situations happens. Some hunters kills
animals to sell their parts in the illegal market. For example, tigers are
killed for their furs and bones, while elephants for their trunks.
Besides that, habitat destruction is another reason that caused to
animal extinction. In these modern world, our planet is altered and modified to
fulfill the demand of development. Usually, the change will occur at a fast
pace. Thus, the animals lives there will have no time to react and adjust to
the new environment and circumstances. They face difficulty to gather enough
food to survive or Not only animals,
buat also plants species will be endangered. The reasons for this is that
habitat destruction will caused the soil loss its microbes that support
tropical forest.
Not only that, another factor for species extinction is pollution.
Pollution will automatically changes the habitat of animals. It plays a significant
role in extinction. For an example, water pollution is harmful to be drink by
animals. Furthermore, toxic waste from industrial sectors pollute the food
chain and devastates the animals. As a result, there will be lesser of safe
food and drinks. Imagine if this happens to a span of animal living area, all
the animals species that lived there will be in a great danger and thus,
extinction will happens in a blink of an eye.
