Human wastes and global warming
My ponds are at record low levels this year. This, coupled with drought and heat leaves them susceptible to a lethal algae bloom. The smallest pond died once a few years ago, and now has no fish. The largest pond is filling with algae and coming dangerously close to full cover. Needs rain now.
Enormous blooms of algae painting the waters green, sickly blue, or blood-red. Algae producing toxins making water unsafe to drink or swim in. Making fish, shellfish and crabs unsafe to eat. Generating life-snuffing dead zones of low oxygen and, potentially, producing deadly hydrogen sulfide gas ranging our lakes, seas, and oceans.
This is what happens when the world is forced to warm, when run-off due to climate change induced extreme rainfall events increases, when the land that run-off comes from is loaded with fossil fuel based fertilizers, and when fossil fuel burning itself generates a constant fall-out of nitrogen from the skies. In ancient hothouse events, similar forces generated mass extinctions in the world’s waters. And through fossil fuel burning we’re setting off a related hothouse type stress to the life-giving liquid we all rely upon. A stress that is yet worsened due to the efficiency with which we are…
