Clearly another one whizzed right past that pointy little head.  In fact, I do NOT care about all living things.  Here, in descending order, is my list of the ten living things I care about least:

10) Pacific hagfish (Eptatratus stoutii)

9)   Mosquitofish (Gambusia affinis)

8)   Swine (Sus scrofa)

7)   Starlings (Sturnus vulgaris)

6)   Cockroaches (Periplaneta americana)

5)   Gnats (Culex pipiens)

4)   Chytrid fungus (Batrachochythria dendrobatidae)

3)   Dog Tapeworms (Dipylidium caninum)

2)   Ringworm fungus (Dermophycosis spp.)

1)   Roy Anthony (Homo patheticus)

I acknowledge that all except the last probably do serve some purpose--at least within their natural ranges.
