Phytoplankon - microscopic marine plants - could help prevent global warming. How would they do this? And is it right for man to interfere with nature in a bid to save the planet?Key facts
- Phytoplankton are tiny marine organisms which live in their billions in the oceans around the world and form the basis of marine food chains.
- Phytoplankton reduces the amount of carbon dioxide in the atmosphere by absorbing the gas and releasing oxygen through photosynthesis.
- Due to water pollution and global warming the concentration of phytoplankton in the oceans is reducing.
- Human ability to affect phytoplankton growth has both benefits and threats; managing nature is never straightforward.
