What would you name the duck and why?
The "poison" in a snake or spider is simply its way of defending itself against predators (would you rather they carried guns?). Even larger animals protect themselves from predators by using their teeth, claws, horns, and/or sheer size (aren’t you glad bears don’t use bazookas?).
Spiders eat insects (flies, mosquitoes, moths, gnats, etc.). Without spiders, the insect populations would over run the planet, decimating plants (which we humans need for air and food). Spiders have the same motto as many humans – “if you don’t bother me I won’t bother you”.
Snakes eat rodents (mice, gophers, moles, etc.). Sure rattlesnakes are poisonous, but they help keep down the rodent population. I don’t want to meet a rattlesnake, but I’m thankful they’re out there eating the rats that ravage my garden (lizards too). Snakes too have the motto, “if you don’t bother me I won’t bother you”.
Many plants and fungi are non-edible to humans. That doesn’t make them “bad”. "Toadstools" are actually mushrooms. Mushrooms are simply the flower of a much larger fungus organism that dwells underground. That organism helps break down dead material (leaves, grass, wood, etc.) so that plants are able to use it. The mushrooms we see are merely the reproductive part of the organism. Without mushrooms, the planet would be overrun by all the dead trees and other such mater.
Maggots are very useful at braking down matter. Doctors even use them to help heal people (maggots eat the dead and infected skin around wounds). Roaches also help break down feces and rotting matter. Yes, we find these buggers to be disgusting (much like the person who cleans out septic tanks or hauls away our garbage). However, they are necessary and beneficial for life on this planet. I don’t mean to sound gross, but what do you think happens to dead bodies? These (and other) animals help break them down (nature’s recyclers). Otherwise, we’d be up to our necks in dead bodies (human and animal).
We may not fully understand it, but every creature on this planet has a role to play in making it possible for humans to live here.
