Ode to Mother Nature

Wondering about the size of this place
This world that we live in today
Where do we go to get a look at it all?
Do we have all the time we need?

Mother Nature’s beauty is so spread out
Its as if she has no concept of space
But let her have her freedom to roam
As she spreads her pollen and seed.

I am thankful she always leaves her trace
So I can enjoy all her beauty
How I would love to see the look on her face
But to her I am just one spot very small

I will continue to honor her work and her grace
Even though some in the world watch it fall

Here are the rules for a bref double:

• 4 stanzas: 3 quatrains (or 4-line stanzas) and 1 couplet (or 2-line stanza)
• 3 rhymes: an A rhyme, B rhyme, and C rhyme
• The A and B rhymes appear twice in the first 3 stanzas and once each in the couplet
• The C rhyme is the final line in each of the quatrains
• Each poem has a variable line length, but the lines should be consistent within each poem
