depending on what you mean by "extreme heat and cold" and maybe "deadly animals", that would describe much of the middle of the country.
"Deadly animals"? Dogs, typically just above unarmed humans in the food chain, are everywhere. All that separates them from bears and big cats is good behavior.
I did some Census work in 2010, and around noon I went to a house whose human inhabitants had left, but their four Rottweilers remained. I must have looked the wrong way at them. They did not slowly approach the door; they charged it. I was not sure how long the latch would last. I was able to back away slowly to my car. Those dogs must have thought that I was a burglar.
They suggested that they would attack as a group, and four such dogs make for all practical purposes one
tiger. Remember that dogs have most of the usual characteristics of animals such as bears and Big Cats that we recognize as potential man-eaters: power, strength, agility, speed, cunning, and voracity. Their good behavior is all that keeps them from killing us. But remember: their good behavior depends upon our good behavior in their presence. Burglars of course are meat.
Most instances of lethal attacks of large predators upon people result from violation of that animal's territory. Unarmed, we do not defend ourselves well from any such animals, including dogs. Even the kitten-sized Yorkshire terrier can give people injuries requiring hospitalization. Bites and scratches (watch those claws!) are obvious enough, but any knock-down or take-down is effectively a fall, dangerous enough in its own right.
The 'trained attack dog' is less capricious than the ordinary dog, but it has been trained to attack much like a leopard, an animal within the range of size of dogs. It attacks without warning, not giving any preliminary roars -- excuse me, barks -- that scare one.
So -- don't burglarize houses. Don't lurk in shrubbery with the intention of committing a mugging. Just don't make a leopard or bear out of one large dog, or a tiger out of a pack of dogs.
Danger is all relative. The most dangerous animal is another human being, especially one working in concert with a murderous State. More people were killed in any of several Nazi murder camps than by all the bears, Big Cats, wolves, dogs, hyenas, crocodiles, and alligators combined. Second-most-dangerous is the mosquito, vector of malaria. For some, a bee sting is more dangerous than a bear attack.
Some people still smoke. Some people still speed or drive drunk. Some people stick around with abusive spouses. Go figure.
