I am no biologist (as you'll soon see), and I realize that all the living things here on Earth are supposed to be here for some reason, such as worms are good for the soil, spiders and birds eat the other bugs, ants and bees do their jobs as well, etc. However, there are definitely some things that I wonder what their purpose in the universe is...
Here is a list of creatures that I believe if they were to disappear tomorrow, very few (if any) other living things would miss them:
Ticks
Gnats
Mosquitos
Jellyfish
Sloths
Talk Show Hosts
and, of course Politicians
I would have also included pigeons in this list, however, it appears that they are now all employeed by
Google. Here is a
job description for them. Later.
