All good. Im sure all the animals on planet earth can get a water filter for themselves.

Geography is the study of places and the relationships between people and their environments. Geographers explore both the physical properties of Earth’s surface and the human societies spread across it. They also examine how human culture interacts with the natural environment and the way that locations and places can have an impact on people. Geography seeks to understand where things are found, why they are there, and how they develop and change over time. Read more...

Untapped market. Pun intended.
"We have made the planet inhospitable to human life by irreversibly contaminating it now so that nothing is clean anymore. And to the point that's it's not clean enough to be safe", he said.
"We have crossed a planetary boundary", he said, referring to a central paradigm for evaluating Earth's capacity to absorb the impact of human activity.
"I'm not super concerned about the everyday exposure in mountain or stream water or in the food. We can't escape it... we're just going to have to live with it." "But it's not a great situation to be in, where we've contaminated the environment to the point where background exposure is not really safe."
WTF? It's not safe but you're not concerned?
Also, fuck Dupont.
Wait, I thought that when water evaporated, it became completely pure water vapor. Isn’t that why we get salt crystals and the like?
Pure water picks up all manner of chemicals from the air it falls through. If there is an excess of carbon, sulfur, or toxic chemicals, they can get dissolved or carried by the water to the ground.
That's where acid rain came from.
Whoa, that makes sense but is still wild. Thank you!
Coincidentally, that process is how industrial gas scrubbers work. Imagine a showerhead inside a tank with a ton of macaroni pieces. The dirty air comes from the lower side and and a solvent (water works in many cases) pours through the shower. The contaminants dissolve in the water and air is purified (to an extent). That high surface area works wonders to exchange molecules.
Not all elements evaporate, but many do. Atoms/chrmicals/elements/etc are far more complex than the average education would lead one to believe. Water for example isn't even always H2O, there is H3O water. There's also radioactive water that is physically indistinguishable from water, but you know, radioactive.
Interesting, thank you!
