About World Microbiome Day
- Marine microbes produce most of the oxygen we breathe and can absorb as much carbon dioxide as plants do on land.
- Microbes in the soil fix nitrogen – changing it from a gas in the atmosphere to a form in the soil that plants can use to grow.
- Some microbes even have the capacity to break down methane gas, helping to slow climate change.
- In our homes, composting microbes help us recycle our green waste (plants, vegetables, fruits) and recover nutrients to enrich the soil in our gardens.
- Up to a third of the food we consume is produced by microbes. We can use microbes to extend the shelf-life of our foods and prevent food waste by fermenting foods at home.
- At a larger scale, microbes can contribute to the circular economy by converting waste (e.g. food production waste) into fuel and thus provide new and sustainable opportunities for the food and feed production.
Most frequent questions and answers
The 2021 theme is ‘Sustainability’ with a focus on how microbes can contribute to a sustainable future. Despite their ubiquity and diversity, the importance of microbes for maintaining healthy global ecosystems is often overlooked. Microbes already have a tremendous effect on the health and balance of the environments we live in.
