Most mothers are aware that breast milk helps boost their baby’s immune levels, but up to now it has been thought that it is mainly because of the mother’s antibodies found in human milk.
Australian Rivers Institute’s Assoc. Prof. Peter Pollard has researched rainforest lakes and rivers to test a provocative theory. The respiration of bacteria living and ‘breathing’ in these freshwater ecosystems is a major pathway for the return of rainforest carbon back to the atmosphere as the greenhouse gas carbon dioxide.
