Best answer: I feel like it's an evolutionary thing. Waaay back in the day, humans had to constantly fight and kill predators to survive as well as hunt and kill prey so they could eat. As time went on and we evolved and progressed to the point we're at now, the need to fight and hunt for survival is gone. But I think... show more

Like, isn't that useless, to be scared or find lizards disgusting, if they can't really hurt us? Plus, they eat other insects that could hurt they actually benefit us Don't say "I'm not scared of them"/"I don't find them gross". You *do* know that most others show more

How I see it is why would we be dead forever? It’s hard to explain how I think. So think about this: why would we be DEAD FOREVER?

Best answer: The world is full of mutts. I can remember back when I was a kid (I am 83) there were kids who would say, "I am a full blooded such and such." Probably their own parents didn't know who were all of their 8 great grandparents. Nations have invaded and occupied others and the original population... show more

Best answer: No. The human body converts food into fuel by (over-simply stated) burning (oxidizing) that food. The matter - the elements that make up the food - do not disappear when digested. The nutritious elements are utilized by the body but eventually excreted (typically in different form). The non-nutritious elements are... show more

So as a black person, I should be under the sun because my ancestors survived in Africa exposed to high UV sun exposure and this is my habitat. So whats the consequences of not living in my habitat? I don't live in a hot country.

Best answer: Probably. It's unfair to say "mice" or "rats" which aren't single species. Sure, there are more mice than humans, but that's combining a couple of dozen species of mice, which is unfair. Similarly, we (probably) outnumber any individual rat species. Oddly, I can't find any... show more
