十四年才能修成正果(a worm turns into a moth in 14 years time)

In Artic circle, In winter, the temperature is under -70 celcius. a lamp moth worm needs 14 years time to go into cocoon and to be a moth.
In winter, the worm is frozen.
In summer, It is only a few weeks time. the worm wakes up and take food-leaves.
It needs 14 years time to take enough food/energy to become a cocoon.
In the 14th year, It becomes an cocoon and a moth, and then mating.
Afer watching this episode- "Frozen Planet, The Epic Journey" from Pearl Channel, last night,

I think, ...
The worm can succeed to become a moth in such tough environment.

Why do we-human being not do our best to have a better life in future, physically and mentally?在北極圈的冬季，溫度只有攝氏零下70度。一隻燈蛾蠕蟲需要14年的時間去變繭和飛蛾。

在冬季，蠕蟲被凍結。

在夏季，這是只有幾個星期的時間。該蠕蟲醒來進食葉子。

它需要在14年的時間裡採取足夠的食物/資成為一個繭。

在14年中，它變成了繭和蛾，然後交配。

Afer看這個情節，“冰凍星球，史詩般的旅程”我認為，...

該蠕蟲可以成功，成為蛾在這樣艱難的環境中。

為什麼我們人類沒有竭盡所能在未來有更好的生活，身體和精神上呢？Reference :蛾 - moth
