The theme for World Environment Day 2012 is ‘Green Economy: Does it include you? A Green Economy is “one that results in improved human well-being and social equity, while significantly reducing environmental risks and ecological scarcities”. In its simplest expression, a green economy can be thought of as one which is low carbon, resource efficient and socially inclusive. A Green Economy thus reduces carbon emissions and pollution, enhances energy and resource efficiency, and prevents the loss of biodiversity.
The importance of microbes on green economy is becoming more prominent. Their biosynthetic capabilities have been valuable in finding solutions for several problems to mankind have encountered in maintaining the quality of the environment. Researchers have been hard at work developing green energy from bacteria, fungi and algae. Green technologies such as bio-fuels, bio-plastics, bio-gas, electricity generation and waste treatment harnessing the capabilities of microbial systems for clean, alternative energy resources with considerable success.
Many different species of microorganisms not only play a key role in promoting bio-diversity and ecosystem stability, but also been used as bio-sensors for environmental monitoring. In this issue, article on probiotics and microbial insecticides review a few important applications of bacteria and fungi to human and animal health. Other interesting reports on microorganisms are also available.
