Environment Agency faces landfill tax bill worth millions to clear illegal waste Exclusive: โ€˜extremely unhelpfulโ€™ policy seen as deterrent to clearing thousands of dump sites across England

The government canโ€™t afford to clear up the gigantic waste mountain because it would have to pay millions of pounds to the government.

So will someone please fund us?!
@matehg.bsky.social, Marc, Shamik and I have been working tirelessly to secure funding to explore this important knowledge gap

Weโ€™ve started digging into these interactions, in the field and in the lab, thanks to small consumables budgets, studentships and fieldwork grants. But this only scratches the surface of whatโ€™s needed

Why this matters:

Soils store more carbon than the atmosphere and vegetation combined ๐ŸŒฒโ›…

Even small reductions in microbial CUE could weaken soils as carbon sinks ๐Ÿฆ 

This adds a biological feedback to climate change that is overlooked in carbon-cycle models ๐Ÿ“ˆ

We think that when soil microbes are exposed to antimicrobial compounds & warming, they may allocate more carbon to defence and maintenance, than to growth ๐Ÿฆ 

This lowers their carbon-use efficiency, meaning more carbon is respired as COโ‚‚ & less is retained in biomass and stored in the soil ๐ŸŒฑ

Soils worldwide are warming - fastest in the Arctic ๐Ÿปโ€โ„๏ธ where vast amounts of Earthโ€™s carbon is stored ๐ŸŒก๏ธ

Simultaneously, global antibiotic use is rising ๐Ÿ’‰ and antimicrobial compounds are increasingly leaking into natural environments ๐Ÿ’Š

What does this mean for the microbes controlling soil carbon? ๐Ÿฆ
