The Evolution of Acid Rain

acid rain is a naturally occurring phenomenon. When volcanoes go off, they blow a ton of sulfur into the sky. And that causes the rain to take on the sulfur and then the rain gets acidic. So there's an extinction event that happened before the dinosaurs all died out about 250 million years agoThat might actually have been caused by acid rain. Since the 1940s, the rain has been getting 2% more acidic every single year. Nobody really notices it doesn't cause any health effects. There's no reason why you would notice this.
