Humans impact the physical environment in many ways: overpopulation pollution burning fossil fuels and deforestation. Changes like these have triggered climate change soil erosion poor air quality and undrinkable water.
How an increase in the acidity of ocean water can affect humans corals and other ocean creatures with calcite skeletons?
Coral. Many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing CO2 levels and decreasing pH in seawater. For example increasing ocean acidification has been shown to significantly reduce the ability of reef-building corals to produce their skeletons.
How does ocean acidification affect coral?
What are steps that can be taken to reduce the impact humans have on ocean acidification?
The most effective way to limit ocean acidification is to act on climate change implementing solutions to dramatically reduce the use of fossil fuels. If we dramatically cut our global warming emissions and we limit future warming we can significantly reduce the harm to marine ecosystems.
