Nature is never at fault. Nature does what evolution designed it to do.
Feeding alligators will alter their natural behavior. That alligator heard human splashing around and was hoping for a free meal. A normal gator, would hear all that splashing and avoid that area.
I don't think we need a poll here, but I would guess a significant majority of the parents on here would never let a toddler in that water after dark.
We do blame people for shark attacks. As this forums most likely shark attack victim, I know I stand a significantly higher risk of a provoked attack. Unprovoked, a swimmer just in the wrong place at the wrong time. Provoked, spearfishing and any feeding activities. I have guided a few spearfisherman, and I do like diving with sharks. If I get bit, it won't be nature, it will be a shark that was fed by humans, or knows the sound of a spear gun.
I have to respectfully disagree with you here.. unprovoked, no-human-at-fault, accidents do happen. That's why they're always so tragic when they do happen.
I am also a diver, very much an avid diver before my son, have been since age 10..and diving is the #1 reason for my move to Key West. I have had many shark dives all over the world, and I'm always very careful, I don't consider a shark attack high risk..because they are so rare, with divers and with beach goers.
I also surf (not well), and have surfed in Costa Rica 20+ days.. the biggest danger to surfers in CR is Crocodiles, not sharks, I know the crocs are most likely somewhere around..but I surf anyway.
I also kayak in waters that contain venomous snakes.. and I get out of my kayak to swim and do a rope jump.
I camp where there are bears around.
I've never been attacked during any of the above, and I pray that neither myself or a loved one ever will be attacked. However, I think it is absolutely horrible and wrong to blame the victim or guardians if those attacks would happen.
The Lane Graves incident got to me.. badly. I swam in that lagoon with my parents and siblings growing up...we all were fully aware that there are gators in Florida freshwater.,..also, less than 9 months prior to the Lane Graves accident, my son was sitting in that water. I KNEW that there were alligators in there, my Parents also knew.. yet Neither I nor them would never think that this would happen to me or my loved ones.
This is why the fence arguments are stupid. The gators have always been there, this was just a horrific accident of nature...it didn't mean that there is a sudden problem, it's just a side effect of wildlife, one that we never want to see.. so the reactions are to build a bubble around us.
The Graves handled it like I would hope that many would.. as realizing that sometimes bad things happen to good people, but you can make good from tragedy.
