marine organisms

Oceans and seas absorb significant amounts of carbon dioxide (CO₂) from the atmosphere. With increased uptake of CO₂, the pH level of seawater decreases, making it more acidic. This chemical change affects the development of marine organisms. Indirectly, humans will also be affected, for example through the effects on commercially important species in fisheries and aquaculture.

The German Environment Agency is committed to protecting the oceans, which are more important than ever. They buffer climate change, host biodiversity, provide food and raw materials, serve as living and recreational spaces, and are transport routes. At the same time, the North and Baltic Seas face many human activities, leaving their marine environment in poor condition.
