Metaphor

Descriptive Metaphor:

"Humans are to planet as: A plant is to it's soil"

I imagine a plant whose roots suck the rich nutrients from the soil and also takes the water. The plant also uses the soil of support and without the soil a plant can't survive, only its a water plant like sea weed. Sea weed is good with sushi. Anyways Humans need the planet to survive and keep our posture.

"Humans are to planet as: A Drought is to a farm"

A drought simply dries our a farm, making it useless to other species. A Farm is home to many animals and a drought takes away the water supply which key to survival. We humans rob the earth of it's essential properties and by taking for example the trees, we are affecting other animals and their habitat.

Normative Metaphor:

"Humans are to planet as; bee is to a sunflower"

A bee and a sunflower has a special give-give relationship. We humans should more often give then take since the earth or the planet has been giving so much."
