“Ocean Acidification Is a Time Bomb”: This Silent Threat Is Accelerating Extinction and Pushing Earth Toward an Irreversible Collapse

sustainability-times.com/clima

"One of the great paradoxes of ocean acidification lies in its invisibility. Unlike an oil spill or coral bleaching, this threat does not present an obvious visual cue. 'There is no clear alarm signal,' notes Steve Widdicombe, Scientific Director at Plymouth Marine Laboratory. On the shoreline, nothing suggests that water pH has dropped critically. This absence of direct perception complicates public and political awareness, despite already measurable impacts."

Sustainability Times · “Ocean Acidification Is a Time Bomb”: This Silent Threat Is Accelerating Extinction and Pushing Earth Toward an Irreversible Collapse - Sustainability TimesIN A NUTSHELL 🌊 The oceans have surpassed a critical acidification threshold, endangering marine ecosystems and biodiversity. 🐚 Key species like coral reefs and pteropods are severely affected, impacting food chains and coastal economies. 🔬 The invisibility of this threat complicates public awareness and political response, despite its profound impacts. 🌍 Urgent action is needed

How long would it take for humans to go extinct if we stopped having babies?

"If humans were to go extinct, it could open up opportunities for other animals to flourish on Earth. On the other hand, it would be sad for humans to go away because we would lose all of the great achievements people have made, including in the arts and science."

Live Science · How long would it take for humans to go extinct if we stopped having babies?Even though there are 8 billion people on Earth today, a catastrophe could send that number much lower within a few decades.

Living things on Earth always bounce back after a mass extinction, re-speciate and re-populate. It will take all of human ingenuity to make sure that any of us are still around after the ongoing mass extinction that we have caused. We started this way back in the late Ice Age and it has only accelerated since, prominently when we invented agriculture and then industrialism. We didn't know better back then.

@sanderturnhout Wonderful article, thank you, if lost a bit in my phone translation, but the last sentence says it all: "In this way, the portraits of the dodos show that nature restoration is not only about saving a species, but rather about restoring the relationship between people and nature. And that is urgently needed to prevent us from following the path of the dodo ourselves." #extinction #habitatloss #climatechange #pollution #nature
