Impact of Climate Change on Marine Life
Climate change poses a significant threat to marine ecosystems, primarily through its effects on fish populations and key organisms like phytoplankton. Increasing levels of carbon dioxide are making oceans more acidic, which impairs the survival of phytoplankton—essential food for small fish. Warmer water temperatures are leading to the formation of low oxygen dead zones, disrupting marine life growth and reproduction. Furthermore, the destruction of coastal habitats limits breeding grounds for fish, ultimately contributing to the anticipated decline in fish stocks.
