Holobiont concept: how Gut Health Can Impact Environment, Climate Change and Agriculture Sustainability

To better understand how improve animal health and performance will reduce the impact on nature, it is appropriate to comprehend the concept of holobiot. It is defined as a biomolecular network between the host genome, their organelles and all the microbiome associated.

The holobiont theory consider the host and microbiota as a unique entity where cooperation or mutualism is stablish to have the better fitness of both systems. Considering the Earth as interconnection of holobionts, it is possible to understand the cascade impact of the climate change in the environmental, microorganism, animal and human life.

Climate changes will affect the biodiversity in different system and however this could be imperceptive for animal and human at the begin, it would increase the proportion in the time.

The dysbiotic holobiont environmental promote changes in microbiota-host immune axis and abnormal immune response that induce metabolic disease in the host. The mainly objective of the talk will be to brainstorm, at light of scientific literature, the interaction between climate changes impact on soil diversity, crops quality, animal and human microbiota and their consequences in sustainability.
