Changes in the environmental microbiome in the Anthropocene.

Area of Science:

• Microbial ecology and environmental science
• Biogeochemistry and global change research

Background:

• Human activities are a significant driver of environmental change, extending beyond climate and land cover to impact microbial communities.
• These alterations in the microbial world are occurring alongside documented shifts in biodiversity and chemical composition.

Discussion:

• The profound effects of human-induced microbial changes on Earth's biogeochemical processes are critical to understand.
• Global biology and human health are demonstrably influenced by these microbial shifts, highlighting interconnectedness.

Key Insights:

• Human activity is reshaping microbial ecosystems globally.
• Microbial changes directly impact essential biogeochemical cycles and overall planetary health.
• The sustainability of the Anthropocene is intrinsically linked to the state of microbial life.

Outlook:

• Further research is needed to fully elucidate the long-term consequences of microbial alterations.
• Mitigation strategies may be required to preserve ecosystem functions and human well-being.
