You see all kinds of animals drinking from puddles, ponds, etc and they are fine, whereas us humans can’t do it without getting sick.
In: Biology
Almost every (wild) animal is riddled with parasites, microbes or larger critters that are making them less healthy. Meanwhile, humans in developed areas are comparatively parasite free.
Adding a parasite to an infected animal will only marginally change their health, but adding one to an uninfected human can drastically hurt their health.

How many wild animals are wandering your neighborhood, drinking from ponds and getting regular checkups to see that they’re healthy?
Animals get infections and parasites all the time, and just die from them.
Mainly:
* animals do it routinely, so they build up a tolerance, often living in a very limited area; and
* they aren’t always fine but you don’t notice when they suffer or die; people dying is a much bigger deal for risk-averse people who have an extremely long average lifespan and access to medical care.
they dont. wild animals are often not in top condition due to various health condition asscosiated with drinking contaminated water. it’s just they’re wild, and being in wild, showing that you’re sick or unhealthy is bad for your survival and breeding chance.
the animals that are sick enough to display that they’re sick, usually just die from predation, die to their own sickness, or unable to find mates because they are undesirable
Well humans have doubled our average life expectancy partly because we have become safer in what we drink and eat
it affects animals too.
Some die from it too.
Humans have this knowledge and it spares us suffering and death.
That is probably why humans are the most populous species of mammals IIRC.
we arent, we just got sick and tired of people dieing from bad water and can do something about it, so we did.
If you are OK with parasites then drink whatever. Most wild animals are riddled with parasites, even domesticated animals need regular treatment.
We are the only ones who know what parasites are and how they get inside your guts. Wild animals get sick all the time, if they didn’t the parasites would die out
Humans are animals, first. Second, we learned to cook and this changed the way our gut works
