Acid Rain and Its Effects

The video discusses the effects of acid rain on aquatic life, highlighting how it lowers pH levels and increases aluminum, causing stress and mortality in fish. It explains prevention methods like reducing sulfur dioxide emissions and using clean energy. The video also covers the broader environmental impact, including effects on birds and biogeochemical cycles. Technological solutions like scrubbers and catalytic converters are introduced, along with legislative measures like the Clean Air Act. Finally, it addresses the reversibility of acid rain effects, noting that recovery can take centuries.
