Vegetative phase, reproductive phase, then what

I have passed reproductive age.  From the point of view of plants, it is not only passed the vegetative phase, but also the reproductive phase.

It seems that we shouldn't look at life this way, otherwise it's like...

However, photosynthesis provides energy for plants to grow, plants stretch their body under the sun.  This kind of plant life has always been a desirable life. However, in this world, we have to face climate change, face the endless expansion and deforestation by human beings, scary insects, etc.  It seems that plant life is not easy.

我已經過了生育的年齡了，從植物角度來看，那不但是已經過了 vegetative phase，也過了 reproductive phase 嗎？....

好像不能這樣來看人生，不然就好像...。

不過可以靠著光合作用生長、在太陽下舒展身軀的植物人生，一直是一種令人嚮往的生活啊，不過現世要面對氣候變遷，面對人類無止境的擴張砍伐，還有我一直害怕的蟲，植物人生也不見得容易。
