◄Previous: 3 Reflecting on some limitations of metagenomics

# 4 Conclusion

In conclusion, metagenomics is a powerful approach that transformed how scientists study life by allowing them to analyse genetic material from any sample.

Metagenomics makes it possible to explore complex communities of organisms that cannot easily be grown in the laboratory, greatly expanding our understanding of ecosystems and the limits of life. Additionally, metagenomics is a powerful tool at the service of human, animal, and environmental health, with applications ranging from tracking new pathogens, monitoring biodiversity, and discovering useful enzymes and medicines.

At the same time, recognising the limitations of metagenomics is essential for appreciating what it can and cannot do. As sequencing technologies improve and analytical methods become more accurate and accessible, metagenomics will continue to grow as a key tool across many scientific fields.
