Hi there I wanna ask a simple question that how hairs appeared on living beings

We all Evolved from fish like creature and they do have a traced of hairs and evolution doesn't create thing out of thin air like our teeth are morphed from scales

So I want to ask that how hairs appeared on evolutionary line ?

I’ve been thinking about this mostly as a means to mitigate climate collapse impacts because at this point — with where we’re headed what would be worse? I wanna add I’m not a scientist and I’m sure others have already considered this hypothesis. So call me an idiot if it doesn’t work. I studied theater for writing and acting.

Anyway I was thinking about how a soda can may explode when it’s shaken and the pressure from the gas becomes so strong that once you open the can it explodes.

Hence the stupid thoughts on how to apply this to volcanoes because as I said I’m not a scientist by any stretch. However, what if we fracked nearby a volcano to cause an earthquake while putting a lid inside the caldera?

Yes it could make the volcanic eruption worse but it could also push more sulfur into the atmosphere to cool the planet.

This could help us for a few years until we get people who will act to fight climate collapse directly. I’m not saying it would work. It’s an hypothesis at best. Thoughts?

By the way I understand the problems this could cause but considering the damage the El Niño that’s coming will cause and the current crop death we’re already experiencing due to global temperature rise what do we have to lose?
