Do earthworm lives matter? If so, why do we keep feeding them to fishes.?

Earthworm lives matter only insofar as they are of use to us as fertilizer, bait, food, pets, etc. :-)

That's not to say we should disproportionately abuse them on account of being worms, however.

you ever see that illustration
of the little being eaten by the bigger
and it goes up the ladder of life?
everything is food for the higher ups on the food chain.
haha
 

yes, they matter to the fish

Earthworms DO matter, and to a lot more than our wishes as anglers or gardeners.

Like a vast array of invertebrates living on or in the soil they fulfil roles of their own, and not just as food for birds and other animals. Earthworms help aerate the soil by their burrowing, and help break down fallen leaves by eating them.
