First One, Then I Seem None

First I am one, then I seem none,
In death I birth new life.
What’s raised exceeds me,
For on bent knee,
I add to a world that’s rife.

What am I?

A seed. One seed turns into a plant or tree and seemingly disappears. When a plant dies, the seeds can be harvested to create new plants. From a single seed, hundreds more are created, vastly exceeding the original. Gardeners care for plants on bent knee and each new plant helps make the air fresher.

Two long rows lined side by side,
One sole unit can decide,
If the rows will unite or divide.

I Make Men Crazy

I can make men crazy,
I shine when you retire.
I move water without a touch,
My colors may cause you ire.

The moon. The moon has a long association with being crazy (lunar being the basis for a lunatic). It shines at night, when you go to bed. The moon’s gravity creates the ocean tides and when the moon is different colors it can mean bad weather is on its way.
