Plants must have light in order to grow
所以它们为了得到充足的阳光
and will do anything to get as much as they need.
会各出奇招
The forest might appear to be the perfect place for plants to thrive.
森林似乎是 最适合植物生长的地方
Yet down here on the forest floor
但是对刚刚萌芽的新生植物来说
is one of the hardest places imaginable for a young plant to begin its life.
森林的地面是最难讨生活的地方
The canopy above is so thick that only a little sunlight can filter through.
上方的树冠层 浓密到只能透出一丝丝阳光
For this sapling, too little light means death.
这棵树苗得不到足够的阳光 只好黯然退出人生舞台
But plants on the forest floor need not be passive.
但是地面上的植物 也可以主动出击
If the light won't come to them, they can go to the light.
既然这里照不到光 就到有光的地方去
But they still have a problem.
但它们还是有一个问题
The light is 50 metres above them.
有光的地方离地面有五十公尺
So, they must climb.
它们只好往上爬
It's much easier to use another plant as scaffolding.
若能把其他植物当踏脚石 往上爬就轻松多了
