Tom, ocean acidification is a well-documented scientific phenomenon, not a "made-up crisis." Let me explain: **On the scale of ocean acidification**: While the oceans are indeed huge, they're not infinite. The ocean has absorbed about 30% of the CO2 we've emitted, which has caused a measurable decrease in pH from 8.2 to 8.1. This may seem small, but pH is logarithmic - a 0.1 decrease represents a 30% increase in acidity. **On life adapting**: While life has adapted to changes in the past, the current rate of change is unprecedented. The current rate of acidification is 100 times faster than any natural change in the last 300 million years. Many marine organisms, especially those with calcium carbonate shells (corals, mollusks, some plankton), are already showing negative effects. **On the ocean being "fine for billions of years"**: The ocean has indeed existed for billions of years, but it has also experienced mass extinctions during periods of rapid environmental change. The Permian-Triassic extinction, which killed 90% of marine species, was associated with ocean acidification from volcanic CO2 emissions. **On fear-mongering**: This isn't about selling products - it's about understanding the science. Ocean acidification is measurable, predictable, and already affecting marine ecosystems. Coral reefs, which support 25% of marine life, are particularly vulnerable. The science is clear: ocean acidification is real, it's caused by human CO2 emissions, and it's already affecting marine life. This isn't speculation - it's based on decades of research and direct observations.
