More and more native plants in cities will increase microbial diversity and combat the development of noncommunicable diseases such as asthma and inflammatory bowel disease, said researchers at the University of California. South Australia.
In a new article, published in Frontiers in MicrobiologyResearchers at the University of Adelaide have found that people in urban areas badly need more natural habitat to cope with chronic disease rates.
This goal could be achieved through the restoration of microbial biodiversity in urban areas through rewilding.
Lead author, Jacob Mills, of the Environment Institute of Adelaide University, said that evidence indicated that humans needed healthy, natural, and rich environments in bacteria to grow properly in healthy holobionts – a symbiosis between a host and microorganisms dependent on the health of the ecosystem and biodiversity. optimal results for health.
He added that a decrease in biodiversity, including microbial diversity, human habitat resulting from urbanization would be causing the rapid rise in diseases non-communicable in urban populations.
"We are more than humans, cell by cell, we are 57% microbial, we live in ecosystems," Mills said.
"Our symbiotic microbial partners, or our 'old friends', come from our mother and her wider habitat when we are young. These microorganisms play a vital role in our health, especially in the formation and regulation of our immune system.
"In today's urban designs, people are little exposed to their" old friends "and, in part, we have reduced our health due to inadequate training and regulation of the immune system. Most microbes are really beneficial or neutral, they rarely cause disease. "
Researchers say that modern urban housing is poor in macro and microbial biodiversity and discourages contact with the beneficial environmental microbiota.
They also claim that these habitat factors, badociated with diet, antibiotics and others, are badociated with the outbreak of noncommunicable diseases in these societies.
According to the researchers, the restoration of native plant communities in urban areas could have beneficial effects on the health of the generations and generate considerable savings for the health sectors. According to them, if urban catering can reduce health costs by 5%, the European Union could save € 230. 280 million euros a year just for inflammatory bowel disease.
"Restoring plant communities provides habitat for animals and alters soil, water and air conditions, all of which have an impact on the environmental microbiota, thus generating a more natural microbial community" said Mr. Mills.
