Modern civilisation and advanced technology are as natural as wild animals

I'm not sure really, maybe this theory isn't perfect and there are a few flaws in it. I came up with this explanation below but I'm no expert so maybe I'm just talking out of my ass. I just hate to sound like a pompous pseudo-intellectual know-it-all who thinks he's an expert just cos he has a vague understanding of this kind of stuff, and who can never admit when he's wrong, lol.

But it seems to me anyway that (like any organism) everything we do, we do because it would benefit us, whether it will benefit us in the long term or in the short term. The long term benefits are health and the short term benefits are pleasure.

For animals in the wild, pleasurable short term benefits are usually also healthy things that would benefit them in the long term, eg. eating sugary food. A small amount of naturally occurring sugary food (eg. fruits) would be beneficial for animals and they'd never usually have the risk of eating too much of it, so it would be advantageous for them to crave it so that they'll definitely eat it whenever they have the opportunity. So because of that, if they were given an unlimited amount of it, then it would be natural for them to eat so much of it that it would be very unhealthy.

Humans have an unlimited amount of sugary food, however we're unique in that we're aware that eating too much of it is unhealthy. So we choose not to eat it because it would be beneficial to us in the long term. But because animals are unaware and more guided by their instincts, it would be unnatural for them to choose not to eat it if they had the choice. But then people who eat sugary food despite knowing that it's unhealthy are still doing it because it's beneficial, it's just that they're choosing the short term pleasure benefits over the long term health benefits. Same thing for the screens, people are choosing the short term pleasure benefits over the long term health benefits.
