who discovered Victoria Falls

think of the ozone layer as the planet's own natural sunscreen. when you spend as much time out on the open water as i do, you really learn to respect how brutal the sun's rays can be without any protection. that thin layer up there in the atmosphere filters out most of the harmful ultraviolet radiation before it hits us. without it, we'd be looking at some serious health problems, like major skin damage and all sorts of other issues that would make just being outside almost impossible.

it's not just about us humans getting a bad sunburn either. it's the whole ecosystem that would be in trouble. those uv rays can mess with the growth of plants and the tiny organisms at the bottom of the ocean food chain. if those guys start dying off, the whole thing falls apart pretty quickly. keeping that shield intact is honestly the only reason we can live comfortably on this rock, so it's a pretty big deal to keep it in one piece.
