However, you are one syllable short on the second line (6 instead of 7).
Perhaps you can move trees to the end of that line and add one word to the last line (up or out). That would help the flow of ideas as well.
A great little haiku, gives a new perspective on lifes endless cycle.
The last line points to hope over circumstance and can be linked to many things, such as a country ravaged after war, or a family that has suffered a loss.
I love the simplicity of using a haiku- they really get straight to the point. The meaning that I feel behind this is great- even though bad things happen, good things can take their place. Good job :)
