In conventional scientific approaches, degraded ecosystems (e.g. conventional agroecosystems due to tillage and high doses of chemical inputs) are attempted to be revived mainly through nutrients, organic matter and water management. However, they do not provide a complete answer to the issue of sustainability of the ecosystems. It is now reported that sustainability of the ecosystems is an outcome of chemical signaling in the food web, in which microbes have got the central role to play (Seneviratne, 2015). Now, it is also known that developed microbial communities in biofilm mode and their exudates contribute more than their monoculture microbes in reinstating sustainability of the degraded ecosystems through increased biodiversity and ecosystem functioning.

The same concept can be applied to human body ecosystem. It is reported that the intake of antimicrobials like antibiotics is harmful to the human health. Sometimes, people use Probiotics after intake of antibiotics. They are mixtures of beneficial gut bacteria, but not in biofilm mode. Thus, in future medicines, developed microbial communities in biofilm mode and their exudates should be adopted for treating ailments. Then, they would help increase native biodiversity of gut bacteria, thus resulting in enhanced functioning of human body ecosystem for a healthy life.
