Ocean acidification: Herring could benefit from an altered food chain
As soon as they start life, it's all about survival for juvenile young fish. They must learn to catch prey and to escape enemies. Additionally, at this stage of their lives they are highly sensitive to environmental factors such as temperature, oxygen and the pH of the water. Exactly these factors are currently changing on a global scale: temperature is rising, the oxygen content of the ocean is decreasing and more and more carbon dioxide (CO2) from the atmosphere dissolves in the seawater, where it forms carbonic acid and lowers the pH level. But not only directly, also indirectly elevated CO2 affects the survival of fish larvae, because it can change their food supply.
Course Grains Better Than Rice For Health, Environment
Shifting away from white, polished rice to a diet that includes more wheat and coarse grains can improve how Indians deal with micronutrient deficiencies, and reduce greenhouse gas (GhG) emissions associated with paddy cultivation, says a new study.
